AMQPClassic Control
Properties Methods Events Config Settings Errors
An easy-to-use AMQP 0.9.1 client implementation, with support for RabbitMQ extensions.
Syntax
AMQPClassic
Remarks
The AMQPClassic control provides an easy-to-use AMQP 0.9.1 client implementation, and it also supports certain RabbitMQ extensions to the AMQP 0.9.1 specification. The control supports both plaintext and TLS-enabled connections over TCP.
Connecting
The AMQP 0.9.1 transport protocol has two layers: an overall connection between the client and server, and one or more channels running over that connection.
The control implements both layers, so the first step is to initiate the overall connection. Set the AuthScheme, User, Password, SSLEnabled, and VirtualHost properties if necessary, then call the ConnectTo method, passing it the server's hostname and port number. (If the server in question is not running RabbitMQ, disabling the RabbitMQCompatible configuration setting before connecting is also recommended.)
The next step is to create at least one channel, which can be accomplished by using the CreateChannel method. The control allows creating any number of channels, up to the limit specified by the MaxChannelCount configuration setting.
Connecting and Creating a Channel
// The examples in this documentation use a RabbitMQ server, which requires SASL Plain auth.
amqpc1.AuthScheme = AmqpclassicAuthSchemes.smSASLPlain;
amqpc1.User = "guest";
amqpc1.Password = "guest";
amqpc1.SSLEnabled = true;
amqpc1.ConnectTo("amqpclassic.test-server.com", 5671);
amqpc1.CreateChannel("channel");
Once the control has connected to the server, and one or more channels have been opened, the control can begin manipulating exchanges and queues, publishing messages, and creating consumers.
Note that most AMQP 0.9.1 operations can themselves vary in their complexity. The examples below are intentionally simple for the sake of clarity and brevity, but links are provided for many other parts of the control's API where more detail can be found.
Declaring Exchanges
The DeclareExchange method is used to declare (i.e., create, or verify the existence of) exchanges on the server. While all AMQP servers provide a default, direct-type exchange that all queues are bound to automatically (using their name as the routing key), more complex use-cases will often require creating additional exchanges of varying types.
Declaring an Exchange
// Declare a direct-type exchange.
amqpc1.DeclareExchange("channel", "MyExchange", "direct", false, false, false, false);
Exchanges can also be deleted using the DeleteExchange method.
Declaring Queues
The DeclareQueue method is used to declare (i.e., create, or verify the existence of) queues on the server. Unlike with exchanges, the server does not provide any queues by default, so declaring a queue is always necessary (unless one has already been created by another client, or configured ahead-of-time on the server itself).
Declaring a Queue
// Declare a queue.
amqpc1.DeclareQueue("channel", "MyQueue", false, false, false, false, false);
Queues may also be deleted or purged using the DeleteQueue and PurgeQueue methods.
Binding Queues to Exchanges
The BindQueue method is used to bind a queue to an exchange. Exchanges use the information held by their queue bindings to determine which messages to forward to which queues.
Note that all AMQP 0.9.1 servers automatically bind all queues to their default exchange (which is always a direct exchange with no name) using each queue's name as the binding's routing key. This makes it easy to send a message to a specific queue without having to declare bindings; just call PublishMessage, pass empty string for ExchangeName, and the name of the desired queue for RoutingKey.
Binding a Queue to an Exchange
// Bind a queue to an exchange. Messages will only be delivered to the queue if their routing key is "MyRoutingKey".
amqpc1.BindQueue("channel", "MyQueue", "MyExchange", "MyRoutingKey", false);
Queues can also be unbound from exchanges using the UnbindQueue method.
Publishing Messages
To publish a message, populate the Message property's properties, and then call the PublishMessage method.
Publishing a Message
amqpc1.Message.Body = "Hello, world!";
// Publish a message to the server's default (no-name) exchange, using the name of a specific queue as the routing key.
amqpc1.PublishMessage("channel", "", "MyQueue", false, false);
// Publish a message to the "MyExchange" exchange, using the routing key "MyRoutingKey".
amqpc1.PublishMessage("channel", "MyExchange", "MyRoutingKey", false, false);
Note that outgoing messages may be handled differently by the server if the channel they are sent over is in transaction or (for RabbitMQ only) "publish confirmations" mode. Refer to the EnableTransactionMode and EnablePublishConfirms methods for more information.
Receiving Messages
There are two possible ways for the control to receive a message:
- Messages can be asynchronously pushed to the control from the server. At any point in time, the server may push a message to the control from a queue that the Consume method has been used to attach a consumer to.
- Messages can be synchronously pulled from the server by the control. The RetrieveMessage method is used to attempt to pull (or "retrieve") messages from a specific queue.
Regardless of how they are received, all incoming messages cause the ReceivedMessage property's properties to be populated and the MessageIn event to fire.
Receiving a Message
// MessageIn event handler.
amqpc1.OnMessageIn += (s, e) => {
if (e.MessageCount == -1) {
// The server pushed a message to us asynchronously due to a consumer we created.
Console.WriteLine("The server pushed this message to us via consumer '" + e.ConsumerTag + "':");
Console.WriteLine(amqpc1.ReceivedMessage.Body);
} else if (e.DeliveryTag > 0) {
// We pulled a message from a queue with the RetrieveMessage() method.
Console.WriteLine("Message successfully pulled:");
Console.WriteLine(amqpc1.ReceivedMessage.Body);
Console.WriteLine(e.MessageCount + " messages are still available to pull.");
} else {
// We tried to pull a message, but there were none available to pull.
Console.WriteLine("No messages available to pull.");
}
};
// Attach a consumer to "MyQueue".
amqpc1.Consume("channel", "MyQueue", "consumerTag", false, true, false, false);
// Or, try to retrieve a message from "MyQueue".
amqpc1.RetrieveMessage("channel", "MyQueue", true);
Note that the MessageIn event always fires if RetrieveMessage is called successfully, even if there were no messages available to retrieve; refer to MessageIn for more information.

All channels are in normal mode when they are created; there's nothing special about a channel in normal mode.
Channels can be put in transaction mode using the EnableTransactionMode method. While a channel is in transaction mode, all messages published and acknowledgements sent over it will be part of a transaction, and the server will wait to process them until the transaction is either committed or rolled back.
Channels can be put in publish confirmations mode using the EnablePublishConfirms method. While a channel is in publish confirmations mode, the server will acknowledge each message published by the control. The control will wait to fire the MessageOut event until it receives this acknowledgment. (Note that this mode is only available when the RabbitMQCompatible configuration setting is enabled.)
Note: Switching a channel to transaction or publish confirmations mode is a permanent action; the channel will then remain in that mode for the remainder of its lifetime.

This property includes the name of the local host or user-assigned IP interface through which connections are initiated or accepted.
Syntax
amqpclassiccontrol.LocalHost[=string]
Default Value
""
Remarks
The LocalHost property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.
In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the control initiate connections (or accept in the case of server controls) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.
If the control is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).
Note: LocalHost is not persistent. You must always set it in code, and never in the property window.

Default Value
0
Remarks
This property must be set before a connection is attempted. It instructs the control to bind to a specific port (or communication endpoint) in the local machine.
Setting this property to 0 (default) enables the system to choose an open port at random. The chosen port will be returned by the LocalPort property after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this property when a connection is active will generate an error.
This property is useful when trying to connect to services that require a trusted port on the client side.
Data Type
Integer
MessageAppId Property (AMQPClassic Control)
The Id of the application that created the message.

This property is read-only.
Data Type
String
SSLServerCertSubject Property (AMQPClassic Control)
This is the subject of the certificate used for client authentication.
Syntax
amqpclassiccontrol.SSLServerCertSubject
Default Value
""
Remarks
This is the subject of the certificate used for client authentication.
This property must be set after all other certificate properties are set. When this property is set, a search is performed in the current certificate store to locate a certificate with a matching subject.
If a matching certificate is found, the property is set to the full subject of the matching certificate.

Data Type
String
SSLServerCertEncoded Property (AMQPClassic Control)
This is the certificate (PEM/Base64 encoded).
Syntax
amqpclassiccontrol.SSLServerCertEncoded
Default Value
""
Remarks
This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.
When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.
To read or write binary data to the property, a Variant (Byte Array) version is provided in .SSLServerCertEncodedB.
This property is read-only and not available at design time.
Data Type
Binary String
Timeout Property (AMQPClassic Control)
This property includes the timeout for the control.
Syntax
amqpclassiccontrol.Timeout[=integer]
Default Value
60
Remarks
If the Timeout property is set to 0, all operations return immediately, potentially failing with a WOULDBLOCK error if data cannot be sent immediately.
If Timeout is set to a positive value, data is sent in a blocking manner and the control will wait for the operation to complete before returning control. The control will handle any potential WOULDBLOCK errors internally and automatically retry the operation for a maximum of Timeout seconds.
The control will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.
If Timeout expires, and the operation is not yet complete, the control fails with an error.
Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.
The default value for the Timeout property is 60 seconds.
Data Type
Integer
User Property (AMQPClassic Control)
A username to use for SASL authentication.
Syntax
amqpclassiccontrol.User[=string]
Default Value
""
Remarks
This property contains a username to use for SASL authentication.
This property is not available at design time.
Data Type
String
VirtualHost Property (AMQPClassic Control)

Syntax
amqpclassiccontrol.VirtualHost[=string]
Default Value
"/"
Remarks
This property specifies the virtual host to connect to on the server, and is set to / by default.
Note that the configuration of the server defines what virtual hosts are available.
This setting cannot be changed while connected.
This property is not available at design time.
Data Type
String
BindQueue Method (AMQPClassic Control)
Binds a queue to an exchange.
Syntax
amqpclassiccontrol.BindQueue ChannelName, QueueName, ExchangeName, RoutingKey, NoWait
Remarks
This method is used to bind the queue named QueueName to the exchange named ExchangeName. Exchanges use bindings to determine which queues to route messages to.
Multiple bindings between the same queue and exchange with different RoutingKeys and/or arguments are allowed; requests that would create a duplicate binding are ignored. No queue will ever receive duplicate copies of any message, regardless of what bindings are present on the server.
Note that all AMQP 0.9.1 servers automatically bind all queues to their default exchange (which is always a direct exchange with no name) using each queue's name as the binding's routing key. This makes it easy to send a message to a specific queue without having to declare bindings; just call PublishMessage, pass empty string for ExchangeName, and the name of the desired queue for RoutingKey.
ChannelName controls what channel the control will send the request over. While any channel can technically be used, keep in mind that the server will close it if a channel error occurs. For this reason, it is good practice to make requests such as this one using a channel that is not involved in message publishing or consumption.
QueueName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters.
The server's default exchange may be specified by passing empty string for ExchangeName. Otherwise, ExchangeName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters.
The RoutingKey parameter specifies the binding's routing key. Exchanges that use routing-key-based logic make some sort of comparison between the routing keys of incoming messages and this value to decide which messages should be forwarded to the specified queue. Examples of exchange types which use routing keys include:
- direct exchanges, which compare (for equality) the routing keys of incoming messages to the routing keys of each queue bound to them.
- topic exchanges, which match the routing keys of incoming messages against the routing pattern of each queue bound to them.
Not all exchange types make use of routing keys, in which case empty string can be passed for the RoutingKey parameter. Examples of exchange types which don't use routing keys include:
- fanout exchanges simply forward incoming messages to all queues bound to them, unconditionally.
- header exchanges only forward messages that include certain headers. When binding a queue to a header exchange, add items to the Arguments collection to describe the headers that eligible messages must have, and whether they must have any or all of those headers.
Note that the format of the RoutingKey parameter and/or the content of the Arguments collection may differ slightly between server implementations. Refer to your server's documentation to determine what it expects to receive for each exchange type that it supports.
The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.
An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:
- No queue with the given QueueName exists.
- No exchange with the given ExchangeName exists.
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
Binding a Queue to an Exchange
// Bind a queue to an exchange. Messages will only be delivered to the queue if their routing key is "MyRoutingKey".
amqpc1.BindQueue("channel", "MyQueue", "MyExchange", "MyRoutingKey", false);
CancelConsume Method (AMQPClassic Control)
Cancels an existing consumer.
Syntax
amqpclassiccontrol.CancelConsume ChannelName, ConsumerTag, NoWait
Remarks
This method requests that the server cancel the consumer identified by the given ConsumerTag on the channel specified by ChannelName.
The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.
An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because no consumer with the given ConsumerTag exists.
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
CloseChannel Method (AMQPClassic Control)
Closes a channel.
Syntax
amqpclassiccontrol.CloseChannel ChannelName
Remarks
This method closes the channel named ChannelName and removes it from the Channels properties.
If no channel with the given ChannelName exists, an exception will be thrown.
CommitTransaction Method (AMQPClassic Control)
Commits the current transaction for a channel.
Syntax
amqpclassiccontrol.CommitTransaction ChannelName
Remarks
This method commits the current transaction for the channel with the given ChannelName. A new transaction is started immediately after the current one is committed.
Refer to EnableTransactionMode for more information about transactions.
An exception is thrown if a channel with the given ChannelName doesn't exist, or if the server returns an error because the channel does not have transaction mode enabled.
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
Config Method (AMQPClassic Control)
Sets or retrieves a configuration setting.
Syntax
amqpclassiccontrol.Config ConfigurationString
Remarks
Config is a generic method available in every control. It is used to set and retrieve configuration settings for the control.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.
To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).
To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
Connect Method (AMQPClassic Control)
This method connects to a remote host.
Syntax
amqpclassiccontrol.Connect
Remarks
This method connects to the remote host specified by RemoteHost and RemotePort.
For instance:
component.RemoteHost = "MyHostNameOrIP";
component.RemotePort = 7777;
component.Connect();
ConnectTo Method (AMQPClassic Control)
This method connects to a remote host.
Syntax
amqpclassiccontrol.ConnectTo Host, Port
Remarks
This method connects to the remote host specified by the Host and Port parameters. For instance:
component.ConnectTo("MyHostNameOrIP", 777)
Consume Method (AMQPClassic Control)
Starts a new consumer for a given queue.
Syntax
amqpclassiccontrol.Consume ChannelName, QueueName, ConsumerTag, NoLocal, NoAck, Exclusive, NoWait
Remarks
This method instructs the server to start a new consumer on the queue named QueueName; once the consumer is created, it will cause messages enqueued to the specified queue to be delivered to the control over the channel specified by ChannelName.
Consumers last as long as the channel they were created on, or until they are cancelled using the CancelConsume method. Each time a message is delivered to the control, it is immediately added to the IncomingMessages collection, the ReceivedMessage property is populated, and the MessageIn event fires.
ConsumerTag is a string which uniquely identifies the new consumer on the specified channel. If empty string is passed for ConsumerTag, the server will generate a consumer tag automatically when it creates the . this auto-generated consumer tag can then be retrieved by querying the ConsumerTag configuration setting after this method returns.
The NoLocal parameter, if True, ensures that the consumer never consumes messages published on the same channel. (Note that this functionality is not available on RabbitMQ servers, which ignore the NoLocal parameter).
The NoAck parameter controls whether the server will expect the control to acknowledge the each message delivered. Refer to MessageIn for more information about acknowledging messages.
The Exclusive parameter, if True, will cause the control to request that the server create an exclusive consumer. Attaching an exclusive consumer to a queue prevents any other consumers from consuming messages from that queue.
The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.
Additional arguments may be sent with this request by adding them to the Arguments collection. Arguments are server-dependent; refer to your server's documentation to determine if any additional arguments apply for this request.
An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:
- No queue with the given QueueName exists.
- The given ConsumerTag is already in use on the specified channel.
- An exclusive consumer was requested for a queue which already has consumers attached to it.
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
Receiving a Message
// MessageIn event handler.
amqpc1.OnMessageIn += (s, e) => {
if (e.MessageCount == -1) {
// The server pushed a message to us asynchronously due to a consumer we created.
Console.WriteLine("The server pushed this message to us via consumer '" + e.ConsumerTag + "':");
Console.WriteLine(amqpc1.ReceivedMessage.Body);
} else if (e.DeliveryTag > 0) {
// We pulled a message from a queue with the RetrieveMessage() method.
Console.WriteLine("Message successfully pulled:");
Console.WriteLine(amqpc1.ReceivedMessage.Body);
Console.WriteLine(e.MessageCount + " messages are still available to pull.");
} else {
// We tried to pull a message, but there were none available to pull.
Console.WriteLine("No messages available to pull.");
}
};
// Attach a consumer to "MyQueue".
amqpc1.Consume("channel", "MyQueue", "consumerTag", false, true, false, false);
// Or, try to retrieve a message from "MyQueue".
amqpc1.RetrieveMessage("channel", "MyQueue", true);
CreateChannel Method (AMQPClassic Control)
Creates a new channel.
Syntax
amqpclassiccontrol.CreateChannel ChannelName
Remarks
This method creates a new channel with the name ChannelName and adds it to the Channels properties. If a channel with the given ChannelName already exists, an error will be thrown.
Connecting and Creating a Channel
// The examples in this documentation use a RabbitMQ server, which requires SASL Plain auth.
amqpc1.AuthScheme = AmqpclassicAuthSchemes.smSASLPlain;
amqpc1.User = "guest";
amqpc1.Password = "guest";
amqpc1.SSLEnabled = true;
amqpc1.ConnectTo("amqpclassic.test-server.com", 5671);
amqpc1.CreateChannel("channel");
DeclareExchange Method (AMQPClassic Control)
Verifies that an exchange exists, potentially creating it if necessary.
Syntax
amqpclassiccontrol.DeclareExchange ChannelName, ExchangeName, ExchangeType, Passive, Durable, AutoDelete, NoWait
Remarks
This method is used to verify that an exchange named ExchangeName exists; and potentially creates it if no such exchange exists.
ChannelName controls what channel the control will send the request over. While any channel can technically be used, keep in mind that the server will close it if a channel error occurs. For this reason, it is good practice to make requests such as this one using a channel that is not involved in message publishing or consumption.
ExchangeName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters, and must not begin with amq. unless the Passive parameter is True.
ExchangeType specifies the exchange type. All servers support the direct and fanout exchange types, and most should also support the topic and header exchange types. Some servers may support additional, custom exchange types as well. Refer to your server's documentation for more information about each exchange type, and to determine what exchange types it supports other than direct and fanout.
If Passive is True, the server will only verify that an exchange with the given ExchangeName actually exists (regardless of how it is configured).
If Passive is False, and no exchange named ExchangeName currently exists, the server will create one.
If Passive is False, and there is a preexisting exchange named ExchangeName, the server will verify that its current configuration matches the given parameters and arguments.
Durable specifies what happens to the exchange in the event of a server restart. Durable exchanges will be recreated, while non-durable (transient) exchanges will not.
AutoDelete specifies whether the server should automatically delete the exchange when all queues have been unbound from it. Note that this parameter is only sent if the RabbitMQCompatible configuration setting is enabled; it is ignored otherwise.
The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.
Additional arguments may be sent with this request by adding them to the Arguments collection. Arguments are server-dependent; refer to your server's documentation to determine if any additional arguments apply for this request.
An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:
- One of the parameter constraints described above was violated.
- One of the verification cases described above fails.
- The value passed for ExchangeType did not correspond to an exchange type supported by the server.
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
Declaring an Exchange
// Declare a direct-type exchange.
amqpc1.DeclareExchange("channel", "MyExchange", "direct", false, false, false, false);
DeclareQueue Method (AMQPClassic Control)
Verifies that a queue exists, potentially creating it if necessary.
Syntax
amqpclassiccontrol.DeclareQueue ChannelName, QueueName, Passive, Durable, Exclusive, AutoDelete, NoWait
Remarks
This method is used to verify that a queue named QueueName exists; and potentially creates it if no such queue exists.
After each successful call to this method, the control populates the QueueMessageCount property, as well as the QueueConsumerCount and QueueName configuration settings. Refer to each one for more information.
ChannelName controls what channel the control will send the request over. While any channel can technically be used, keep in mind that the server will close it if a channel error occurs. For this reason, it is good practice to make requests such as this one using a channel that is not involved in message publishing or consumption.
If creating a new queue, empty string can be passed for QueueName to have the server automatically generate a name for the new queue (which can then be retrieved using the QueueName configuration setting). In all other cases, QueueName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters, and must not begin with amq. unless the Passive parameter is True.
If Passive is True, the server will only verify that a queue with the given QueueName actually exists (regardless of how it is configured).
If Passive is False, and no queue named QueueName currently exists, the server will create one.
If Passive is False, and there is a preexisting queue named QueueName, the server will verify that its current configuration matches the given parameters and arguments.
Durable specifies what happens to the queue in the event of a server restart. Durable queue will be recreated, while non-durable (transient) queue will not. (Note that the messages in durable queues will still be lost unless they are marked as persistent.)
Exclusive, if True, indicates that the queue may only be accessed by the current connection. Exclusive queues are deleted when the current connection closes.
AutoDelete specifies whether the server should automatically delete the queue when all consumers have finished using it. (Note that auto-delete queues aren't eligible for deletion until after a consumer attaches to them for the first time.)
The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.
Additional arguments may be sent with this request by adding them to the Arguments collection. Arguments are server-dependent; refer to your server's documentation to determine if any additional arguments apply for this request.
An exception is thrown if no channel with the given ChannelName exists, if QueueName empty string and NoWait is True, or if the server returns an error because:
- One of the parameter constraints described above was violated.
- One of the verification cases described above fails.
- An attempt was made to verify (i.e., the Passive parameter was True) another connection's exclusive queue.
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
Declaring a Queue
// Declare a queue.
amqpc1.DeclareQueue("channel", "MyQueue", false, false, false, false, false);
DeleteExchange Method (AMQPClassic Control)
Deletes an exchange.
Syntax
amqpclassiccontrol.DeleteExchange ChannelName, ExchangeName, IfUnused, NoWait
Remarks
This method is used to delete an exchange.
ChannelName controls what channel the control will send the request over. While any channel can technically be used, keep in mind that the server will close it if a channel error occurs. For this reason, it is good practice to make requests such as this one using a channel that is not involved in message publishing or consumption.
ExchangeName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters, and must not begin with amq..
When IfUnused is True, the server will only delete the exchange if no queues are bound to it.
The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.
An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:
- The value passed for ExchangeName fails one or more of the constraints described above.
- No exchange named ExchangeName exists. (This does not apply for RabbitMQ; attempting to delete a non-existent exchange will always succeed.)
- The IfUnused parameter was True, but the exchange still had one or more queues bound to it.
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
DeleteQueue Method (AMQPClassic Control)
Deletes a queue.
Syntax
amqpclassiccontrol.DeleteQueue ChannelName, QueueName, IfUnused, IfEmpty, NoWait
Remarks
This method is used to delete the queue named QueueName.
After each successful call to this method, the control populates the QueueMessageCount property with the number of messages deleted along with the queue. (Note that this does not occur if the NoWait parameter is set to True.)
ChannelName controls what channel the control will send the request over. While any channel can technically be used, keep in mind that the server will close it if a channel error occurs. For this reason, it is good practice to make requests such as this one using a channel that is not involved in message publishing or consumption.
QueueName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters, and must not begin with amq..
When IfUnused is True, the server will only delete the queue if no consumers are attached to it.
When IfEmpty is True, the server will only delete the queue if it has no messages in it. (When IfEmpty is False, servers will typically move any remaining messages to a dead-letter queue, if one is available.)
The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.
An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:
- The value passed for QueueName fails one or more of the constraints described above.
- No queue named QueueName exists. (This does not apply for RabbitMQ; attempting to delete a non-existent queue will always succeed.)
- The IfUnused parameter was True, but the queue still had one or more consumers attached to it.
- The IfEmpty parameter was True, but the queue still had one or more messages in it.
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
Disconnect Method (AMQPClassic Control)
This method disconnects from the remote host.
Syntax
amqpclassiccontrol.Disconnect
Remarks
This method disconnects from the remote host. Calling this method is equivalent to setting the Connected property to False.
DoEvents Method (AMQPClassic Control)
This method processes events from the internal message queue.
Syntax
amqpclassiccontrol.DoEvents
Remarks
When DoEvents is called, the control processes any available events. If no events are available, it waits for a preset period of time, and then returns.
EnablePublishConfirms Method (AMQPClassic Control)
Enables publish confirmations mode for a channel.
Syntax
amqpclassiccontrol.EnablePublishConfirms ChannelName, NoWait
Remarks
This method enables publish confirmations mode for the channel with the given ChannelName.
While a channel is in publish confirmations mode, the server will acknowledge each message published by the control. The control will wait to fire the MessageOut event until it receives this acknowledgment. (Note that this mode is only available when the RabbitMQCompatible configuration setting is enabled.)
Note that a channel will stay in publish confirmations mode, once enabled, until it is deleted.
The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.
An exception is thrown if the RabbitMQCompatible configuration setting is currently False, if no channel with the given ChannelName exists, or if EnableTransactionMode has been called for the specified channel previously.
EnableTransactionMode Method (AMQPClassic Control)
Enables transaction mode for a channel.
Syntax
amqpclassiccontrol.EnableTransactionMode ChannelName
Remarks
This method enables transaction mode for the channel with the given ChannelName.
While a channel is in transaction mode, all messages published and acknowledgements sent over it will be part of a transaction, and the server will wait to process them until the transaction is either committed or rolled back.
To commit the current transaction on a channel, call CommitTransaction; and to roll it back (and discard the messages and acknowledgements that were part of it), call RollbackTransaction.
Keep in mind that, according to the AMQP 0.9.1 specification:
- A new transaction is always started immediately after committing or rolling back the current one, which means that...
- ...a channel will stay in transaction mode, once enabled, until it is deleted.
- Transactions are only guaranteed to be atomic if all messages published and acknowledgements sent affect a single queue.
- Any messages published on a channel in transaction mode that have the Mandatory or Immediate flags set are not guaranteed to be included in the transaction.
An exception is thrown if no channel with the given ChannelName exists, or if EnablePublishConfirms has been called for the specified channel previously.
Interrupt Method (AMQPClassic Control)
Interrupt the current action and disconnects from the remote host.
Syntax
amqpclassiccontrol.Interrupt
Remarks
This method will interrupt the current method (if applicable) and cause the control to disconnect from the remote host.
PublishMessage Method (AMQPClassic Control)
Publishes a message.
Syntax
amqpclassiccontrol.PublishMessage ChannelName, ExchangeName, RoutingKey, Mandatory, Immediate
Remarks
This method is used to publish the message specified by the Message property to the exchange named ExchangeName over the channel specified by ChannelName.
When this method is called, the message to publish is immediately added to the OutgoingMessages collection, and the MessageOut event fires once it has been sent (or, if the specified channel is in "publish confirmations" mode, after the server has acknowledged it).
Note that all AMQP 0.9.1 servers automatically bind all queues to their default exchange (which is always a direct exchange with no name) using each queue's name as the binding's routing key. This makes it easy to send a message to a specific queue without having to declare bindings; just call PublishMessage, pass empty string for ExchangeName, and the name of the desired queue for RoutingKey.
Note that messages published over channels which are in either transaction or "publish confirmations" mode may be handled differently than they would be on a channel in normal mode. Refer to the EnableTransactionMode and EnablePublishConfirms methods for more information about what each mode entails.
The server's default exchange may be specified by passing empty string for ExchangeName. Otherwise, ExchangeName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters.
The RoutingKey parameter specifies the message's routing key. Whether this parameter needs to be non-empty, and what format it should have if so, depends on the type of exchange it is being sent to. Some exchange types may use information included with the message, such as its MessageHeaders. Refer to BindQueue for more information about how routing keys are used, and to your server's documentation for information on what it expects.
The Mandatory parameter controls what the server should do if the message can't be routed to any queue (either because it isn't eligible for any of the queues bound to the specified exchange because of how their bindings are configured, or because no queues are bound to the exchange in the first place). If True, the server will return the message, at which point the MessageReturned event will be fired. If False, the server will drop the message.
The Immediate parameter controls what the server should do if the message can't be immediately delivered to any consumer (either because it cannot be routed to a queue, or because the queues it can be routed to have no active consumers attached to them). If True, the server will return the message, at which point the MessageReturned event will be fired. If False, the server will queue the message if possible, or drop it if not.
An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:
- The value passed for ExchangeName fails one or more of the constraints described above.
- No exchange named ExchangeName exists.
- The message is rejected for some reason.
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
Publishing a Message
amqpc1.Message.Body = "Hello, world!";
// Publish a message to the server's default (no-name) exchange, using the name of a specific queue as the routing key.
amqpc1.PublishMessage("channel", "", "MyQueue", false, false);
// Publish a message to the "MyExchange" exchange, using the routing key "MyRoutingKey".
amqpc1.PublishMessage("channel", "MyExchange", "MyRoutingKey", false, false);
PurgeQueue Method (AMQPClassic Control)
Purges all messages from a queue.
Syntax
amqpclassiccontrol.PurgeQueue ChannelName, QueueName, NoWait
Remarks
This method purges all messages from the queue named QueueName. Messages which have been sent but are awaiting acknowledgment are not affected.
After each successful call to this method, the control populates the QueueMessageCount property with the number of messages purged from the queue. (Note that this does not occur if the NoWait parameter is set to True.)
ChannelName controls what channel the control will send the request over. While any channel can technically be used, keep in mind that the server will close it if a channel error occurs. For this reason, it is good practice to make requests such as this one using a channel that is not involved in message publishing or consumption.
QueueName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters.
The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.
An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because no queue named QueueName exists.
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
Recover Method (AMQPClassic Control)
Request that the server redeliver all messages on a given channel that have not been acknowledged.
Syntax
amqpclassiccontrol.Recover ChannelName, Requeue
Remarks
This method is used to request that the server redeliver all messages that it previously sent to the control on the channel specified by ChannelName which are still awaiting acknowledgment.
A call to this method may cause the server to redeliver zero or more messages over the channel specified by ChannelName. Those messages will cause the MessageIn event to fire with its Redelivered event parameter set to True.
The Requeue parameter controls how the server should attempt to redeliver the messages awaiting acknowledgment. If set to True, the server will simple put the messages back on their original queues, and they will be delivered like any other queued messages (potentially to other consumers). If set to False, the server will redeliver the messages to the control directly.
An exception is thrown if no channel with the given ChannelName exists, or (for RabbitMQ only) if the server returns an error because Requeue was False. (RabbitMQ only supports setting Requeue to True.)
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
Reset Method (AMQPClassic Control)
This method will reset the control.
Syntax
amqpclassiccontrol.Reset
Remarks
This method will reset the control's properties to their default values.
ResetMessage Method (AMQPClassic Control)
Resets the Message properties.
Syntax
amqpclassiccontrol.ResetMessage
Remarks
This method resets the Message property.
RetrieveMessage Method (AMQPClassic Control)
Attempts to retrieve a message from a given queue.
Syntax
amqpclassiccontrol.RetrieveMessage ChannelName, QueueName, NoAck
Remarks
This method attempts to retrieve a message from the queue named QueueName over the channel named ChannelName.
If a message is retrieved as a result of this method being called, it is immediately added to the IncomingMessages collection, the ReceivedMessage property is populated, and the MessageIn event fires.
Even if no message gets retrieved, the MessageIn event will still fire as long as the request was successful. The server returns the number of available messages in the specified queue in response to all successful retrieve requests, and that count is exposed by MessageIn event's MessageCount parameter. Refer to the MessageIn event for more information.
QueueName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters.
The NoAck parameter controls whether the server will expect the control to acknowledge the retrieved message. Refer to MessageIn for more information about acknowledging messages.
An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:
- No queue with the given QueueName exists.
- The specified queue exists, but is locked or otherwise unavailable to consume from (e.g., an exclusive consumer might be attached to it).
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
Receiving a Message
// MessageIn event handler.
amqpc1.OnMessageIn += (s, e) => {
if (e.MessageCount == -1) {
// The server pushed a message to us asynchronously due to a consumer we created.
Console.WriteLine("The server pushed this message to us via consumer '" + e.ConsumerTag + "':");
Console.WriteLine(amqpc1.ReceivedMessage.Body);
} else if (e.DeliveryTag > 0) {
// We pulled a message from a queue with the RetrieveMessage() method.
Console.WriteLine("Message successfully pulled:");
Console.WriteLine(amqpc1.ReceivedMessage.Body);
Console.WriteLine(e.MessageCount + " messages are still available to pull.");
} else {
// We tried to pull a message, but there were none available to pull.
Console.WriteLine("No messages available to pull.");
}
};
// Attach a consumer to "MyQueue".
amqpc1.Consume("channel", "MyQueue", "consumerTag", false, true, false, false);
// Or, try to retrieve a message from "MyQueue".
amqpc1.RetrieveMessage("channel", "MyQueue", true);
RollbackTransaction Method (AMQPClassic Control)
Rolls back the current transaction for a channel.
Syntax
amqpclassiccontrol.RollbackTransaction ChannelName
Remarks
This method rolls back the current transaction for the channel with the given ChannelName. A new transaction is started immediately after the current one is rolled back.
Refer to EnableTransactionMode for more information about transactions.
An exception is thrown if a channel with the given ChannelName doesn't exist, or if the server returns an error because the channel does not have transaction mode enabled.
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
SetChannelAccept Method (AMQPClassic Control)
Disables or enables message acceptance for a given channel.
Syntax
amqpclassiccontrol.SetChannelAccept ChannelName, Accept
Remarks
This method is used to disable and enable message acceptance for the channel specified by ChannelName.
A channel is always configured to accept messages when first created, allowing the server to freely deliver messages to the control for any consumers that have been created on that channel using the Consume method.
Disabling message acceptance for a channel prevents the server from automatically delivering messages to the control over it; however, it is still possible to use the RetrieveMessage method to synchronously attempt to retrieve a message on a channel with message acceptance disabled.
An exception is thrown if no channel with the given ChannelName exists, or (for RabbitMQ only) if the server returns an error because Accept was False. (RabbitMQ does not support disabling message acceptance.)
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
SetQoS Method (AMQPClassic Control)
Requests a specific quality of service (QoS).
Syntax
amqpclassiccontrol.SetQoS ChannelName, PrefetchSize, PrefetchCount, Global
Remarks
This method is used to request a specific quality of service for a certain scope. When the PrefetchSize and/or PrefetchCount are set for a certain scope, the server will limit how many messages it sends to the control before stopping to wait for one or more of them to be acknowledged.
ChannelName is the name of the channel which is used to send the request. Depending on the server and what Global is set to, it may also be significant to the request itself (refer to the Global parameter's description, below, for more information).
PrefetchSize specifies a window size in bytes; i.e., the server will stop sending messages if the total size of all of the currently unacknowledged messages already sent, plus the size of the next message that could be sent, exceeds PrefetchSize bytes. A PrefetchSize of 0 indicates no limit. (Note that RabbitMQ does not support prefetch size limits.)
PrefetchCount specifies the number of unacknowledged messages the server will limit itself to sending. A PrefetchCount of 0 indicates no limit.
Global specifies the scope which the QoS request should apply to. It is interpreted differently based on whether the server is RabbitMQ or not. Refer to this table:
Global is... | RabbitMQ | Other Servers |
False | QoS will be applied individually to each new consumer on the specified channel (existing consumers are unaffected). | QoS applied to all existing and new consumers on the specified channel. |
True | QoS applied to all existing and new consumers on the specified channel. | QoS applied to all existing and new consumers on the whole connection. |
Keep the following things in mind when using QoS:
- The limits specified by a QoS request only affect messages that require acknowledgment.
- How the server chooses to handle interactions between QoS settings at different scopes is server-dependent.
An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error for any reason.
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
UnbindQueue Method (AMQPClassic Control)
Removes a previously-created queue binding.
Syntax
amqpclassiccontrol.UnbindQueue ChannelName, QueueName, ExchangeName, RoutingKey
Remarks
This method removes a previously-created queue binding.
ChannelName controls what channel the control will send the request over. While any channel can technically be used, keep in mind that the server will close it if a channel error occurs. For this reason, it is good practice to make requests such as this one using a channel that is not involved in message publishing or consumption.
QueueName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters.
The server's default exchange may be specified by passing empty string for ExchangeName. Otherwise, ExchangeName must be a non-empty string consisting only of letters, digits, hyphens, underscores, periods, and colons. It must be no longer than 255 characters.
RoutingKey should be the same routing key used when originally creating the binding that is to be removed. For bindings created using arguments instead of a routing key, the Arguments collection must contain the same items used originally instead.
An exception is thrown if no channel with the given ChannelName exists, or if the server returns an error because:
- No queue with the given QueueName exists. (Does not apply to RabbitMQ.)
- No exchange with the given ExchangeName exists. (Does not apply to RabbitMQ.)
Note that in AMQP, server errors are grouped into "connection errors" and "channel errors", and both are fatal. That is, if the server returns a channel error, it will then close the channel which caused the error; and if it returns a connection error, it will then close the connection. The AMQPClassic control's Error Codes page includes AMQP's various connection and channel errors.
ChannelReadyToSend Event (AMQPClassic Control)
Fires when a channel is ready to send messages.
Syntax
Sub amqpclassiccontrol_ChannelReadyToSend(ChannelName As String)
Remarks
This event fires when a channel is ready to send messages.
ChannelName is the name of the channel.
Connected Event (AMQPClassic Control)
This event is fired immediately after a connection completes (or fails).
Syntax
Sub amqpclassiccontrol_Connected(StatusCode As Integer, Description As String)
Remarks
If the connection is made normally, StatusCode is 0 and Description is "OK".
If the connection fails, StatusCode has the error code returned by the Transmission Control Protocol (TCP)/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.
Please refer to the Error Codes section for more information.
ConnectionStatus Event (AMQPClassic Control)
This event is fired to indicate changes in the connection state.
Syntax
Sub amqpclassiccontrol_ConnectionStatus(ConnectionEvent As String, StatusCode As Integer, Description As String)
Remarks
The ConnectionStatus event is fired when the connection state changes: for example, completion of a firewall or proxy connection or completion of a security handshake.
The ConnectionEvent parameter indicates the type of connection event. Values may include the following:
Firewall connection complete. | |
Secure Sockets Layer (SSL) or S/Shell handshake complete (where applicable). | |
Remote host connection complete. | |
Remote host disconnected. | |
SSL or S/Shell connection broken. | |
Firewall host disconnected. |
Disconnected Event (AMQPClassic Control)
This event is fired when a connection is closed.
Syntax
Sub amqpclassiccontrol_Disconnected(StatusCode As Integer, Description As String)
Remarks
If the connection is broken normally, StatusCode is 0 and Description is "OK".
If the connection is broken for any other reason, StatusCode has the error code returned by the Transmission Control Protocol (TCP/IP) subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.
Please refer to the Error Codes section for more information.
Error Event (AMQPClassic Control)
Fired when information is available about errors during data delivery.
Syntax
Sub amqpclassiccontrol_Error(ErrorCode As Integer, Description As String)
Remarks
The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.
The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.
Log Event (AMQPClassic Control)
Fires once for each log message.
Syntax
Sub amqpclassiccontrol_Log(LogLevel As Integer, Message As String, LogType As String)
Remarks
This event fires once for each log message generated by the control. The verbosity is controlled by the LogLevel setting.
LogLevel indicates the level of the Message. Possible values are:
0 (None) | No events are logged. |
1 (Info - default) | Informational events are logged. |
2 (Verbose) | Detailed data is logged. |
3 (Debug) | Debug data is logged. |
LogType identifies the type of log entry. Possible values are:
- Info: General information about the control.
- Frame: Frame status messages.
MessageIn Event (AMQPClassic Control)
Fires when a message is received; as well as when an attempt is made to fetch a message from a currently empty queue.
Syntax
Sub amqpclassiccontrol_MessageIn(ChannelName As String, ConsumerTag As String, DeliveryTag As Long64, Redelivered As Boolean, ExchangeName As String, RoutingKey As String, MessageCount As Integer, Accept As Integer)
Remarks
This event fires anytime a message is received. There are two possible ways for the control to receive a message:
- Messages can be asynchronously pushed to the control from the server. At any point in time, the server may push a message to the control from a queue that the Consume method has been used to attach a consumer to.
- Messages can be synchronously pulled from the server by the control. The RetrieveMessage method is used to attempt to pull (or "retrieve") messages from a specific queue.
This event also fires anytime RetrieveMessage is called against a queue that currently has no messages available to pull. This is a special case, and results in only the ChannelName and MessageCount event parameters being populated.
Other than that special case, and any exceptions noted below, this event's parameters are populated the same way regardless of the manner in which messages are received.
ChannelName always reflects the name of the associated channel.
ConsumerTag reflects the consumer tag associated with the consumer that caused the server to push the message to the control. (ConsumerTag is always empty for messages pulled from the server by RetrieveMessage since no consumers are involved.)
DeliveryTag reflects the server-assigned, channel-specific delivery tag number for the incoming message.
Redelivered reflects whether the server is redelivering a message that is has delivered previously.
ExchangeName reflects the name of the exchange to which the incoming message was originally published. (If the message was originally published to the server's default exchange, whose name is always the empty string, ExchangeName will also be empty.)
RoutingKey reflects the routing key that the message was originally published with.
MessageCount is always -1 when this event fires due to a message being pushed to the control by the server. When this event fires as a result of RetrieveMessage being called, MessageCount reflects the number of messages still available in the queue the control tried to pull a message from (even if there were no messages available to pull).
The Accept parameter can be set to control how the control responds to the incoming message, if it needs to be acknowledged (if the message doesn't need to be acknowledged, the value set to the Accept parameter is ignored). Valid values are:
- 0 - default: Accept the message; send a positive acknowledgment.
- 1: Silently accept the message; don't send any acknowledgment.
- 2: Accept the message; send a cumulative positive acknowledgment coving this, and all previously unacknowledged, messages.
- 3: Reject the message; send a negative acknowledgment for it, and instruct the server not to return it to the queue.
- 4: Reject the message; send a negative acknowledgment for it, and instruct the server to return it to the queue.
If the value provided for the Accept parameter isn't one of those described above, the default (0) will be used instead.
Receiving a Message
// MessageIn event handler.
amqpc1.OnMessageIn += (s, e) => {
if (e.MessageCount == -1) {
// The server pushed a message to us asynchronously due to a consumer we created.
Console.WriteLine("The server pushed this message to us via consumer '" + e.ConsumerTag + "':");
Console.WriteLine(amqpc1.ReceivedMessage.Body);
} else if (e.DeliveryTag > 0) {
// We pulled a message from a queue with the RetrieveMessage() method.
Console.WriteLine("Message successfully pulled:");
Console.WriteLine(amqpc1.ReceivedMessage.Body);
Console.WriteLine(e.MessageCount + " messages are still available to pull.");
} else {
// We tried to pull a message, but there were none available to pull.
Console.WriteLine("No messages available to pull.");
}
};
// Attach a consumer to "MyQueue".
amqpc1.Consume("channel", "MyQueue", "consumerTag", false, true, false, false);
// Or, try to retrieve a message from "MyQueue".
amqpc1.RetrieveMessage("channel", "MyQueue", true);
MessageOut Event (AMQPClassic Control)
Fires when a message is published.
Syntax
Sub amqpclassiccontrol_MessageOut(ChannelName As String, ExchangeName As String, RoutingKey As String, MessageId As String, DeliveryTag As Long64, Accepted As Boolean)
Remarks
This event fires anytime a message is published; or after an outgoing message has been acknowledged by the server, if the channel it was published on is in "publish confirmations" mode.
ChannelName reflects the name of the channel the message was published on.
ExchangeName reflects the name of the exchange the message was published to. (If the message was published to the server's default exchange, whose name is always the empty string, ExchangeName will also be empty.)
RoutingKey reflects the routing key that the message was published with.
MessageId reflects the message's unique Id, if one was set.
DeliveryTag reflects the channel-specific delivery tag number for the message. (Note that this is only populated for messages published on a channel in "publish confirmations" mode; otherwise it will be set to -1.)
Accepted indicates whether the server published back a positive True or negative False acknowledgment for the outgoing message. Note that this is only valid for messages published on a channel in "publish confirmations" mode; Accepted will always be True messages published on a channel in normal or transaction mode.
Refer to EnablePublishConfirms for more information about channels in "publish confirmations" mode.
MessageReturned Event (AMQPClassic Control)
Fires if a previously published message is returned by the server due to it being undeliverable.
Syntax
Sub amqpclassiccontrol_MessageReturned(ChannelName As String, ReplyCode As Integer, ReplyText As String, ExchangeName As String, RoutingKey As String)
Remarks
This event fires if the server returns a previously published message because it could not deliver it. Typically, messages are only undeliverable in one of the following situations:
- The message was originally published with the Mandatory option enabled, but there were no queues it could be routed to.
- The message was originally published with the Immediate option enabled, but there were no consumers it could be delivered to immediately on any queue it was routed to (or there were no queues it could be routed to).
The ReceivedMessage property will be populated with the returned message.
ChannelName reflects the name of the channel the message was originally published on.
ReplyCode will be an AMQP error code that indicates the reason why the message was returned. (Tip: The AMQPClassic control's Error Codes page includes the various AMQP error codes.)
ReplyText will be a message with further details about why the message was returned.
ExchangeName reflects the name of the exchange to which the message was originally published. (If the message was originally published to the server's default exchange, whose name is always the empty string, ExchangeName will also be empty.)
RoutingKey reflects the routing key that the message was originally published with.
SSLServerAuthentication Event (AMQPClassic Control)
Fired after the server presents its certificate to the client.
Syntax
Sub amqpclassiccontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)
Remarks
During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.
When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.
SSLStatus Event (AMQPClassic Control)
Fired when secure connection progress messages are available.
Syntax
Sub amqpclassiccontrol_SSLStatus(Message As String)
Remarks
The event is fired for informational and logging purposes only. This event tracks the progress of the connection.
Config Settings (AMQPClassic Control)
The control accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.AMQPClassic Config Settings
It is possible to pass empty string for the ConsumerTag parameter when calling the Consume method, in which case the server will auto-generate a consumer tag.
The default value is "en_US", which is supported by all AMQP 0.9.1 servers.
The value of this setting is formatted as a space-separated list of message locales.
0 (None) | No events are logged. |
1 (Info - default) | Informational events are logged. |
2 (Verbose) | Detailed data is logged. |
3 (Debug) | Debug data is logged. |
The default is 65535 (0xFFFF). Note that this value is negotiated during the connection process; if the value provided by the server is lower than the specified value, the server's value will be used instead (and this setting will be updated accordingly).
The default is 2147483647 (0x7FFFFFFF). Note that this value is negotiated during the connection process; if the value provided by the server is lower than the specified value, the server's value will be used instead (and this setting will be updated accordingly).
The value of this setting is formatted as a space-separated list of authentication mechanisms.
This setting does nothing if the RabbitMQCompatible configuration setting is disabled.
Note: Currently this setting will always return "0.9.1", and cannot be changed. The AMQP control may be used instead of this one if AMQP 1.0 support is needed.
It is possible to pass empty string for the QueueName parameter when calling the DeclareQueue method to have the server create a new queue with an automatically generated name, which can then be retrieved by querying this setting.
The default is True.
TCPClient Config Settings
If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.
Note: This setting is provided for use by controls that do not directly expose Firewall properties.

0 | No firewall (default setting). |
1 | Connect through a tunneling proxy. FirewallPort is set to 80. |
2 | Connect through a SOCKS4 Proxy. FirewallPort is set to 1080. |
3 | Connect through a SOCKS5 Proxy. FirewallPort is set to 1080. |
10 | Connect through a SOCKS4A Proxy. FirewallPort is set to 1080. |

Note: This value is not applicable in macOS.
In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.
In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.
The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the control returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.
In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the control initiate connections (or accept in the case of server controls) only through that interface.
If the control is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.
If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.
If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.
The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

Note: This value is not applicable in Java.
By default, this configuration setting is set to False.
0 | IPv4 only |
1 | IPv6 only |
2 | IPv6 with IPv4 fallback |
SSL Config Settings
When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.
Enabling this configuration setting has no effect if SSLProvider is set to Platform.
The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g., 9d66eef0.0, 9d66eef0.1). OpenSSL recommends the use of the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by the following sequences:
-----BEGIN CERTIFICATE-----
... (CA certificate in base64 encoding) ...
-----END CERTIFICATE-----
Before, between, and after the certificate text is allowed, which can be used, for example, for descriptions of the certificates. Refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".
By default, OpenSSL uses the device file "/dev/urandom" to seed the PRNG, and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.
If set to True, the control will reuse the context if and only if the following criteria are met:
- The target host name is the same.
- The system cache entry has not expired (default timeout is 10 hours).
- The application process that calls the function is the same.
- The logon session is the same.
- The instance of the control is the same.

When set to 0 (default), the CRL check will not be performed by the control. When set to 1, it will attempt to perform the CRL check, but it will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.
This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.
When set to 0 (default), the control will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but it will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.
This configuration setting is supported only in the Java, C#, and C++ editions. In the C++ edition, it is supported only on Windows operating systems.
Note: This configuration setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.
Use this configuration setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.
When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList configuration setting.
The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:

By default, the enabled cipher suites will include all available ciphers ("*").
The special value "*" means that the control will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.
Multiple cipher suites are separated by semicolons.
Example values when SSLProvider is set to Platform include the following:
obj.config("SSLEnabledCipherSuites=*");

When TLS 1.3 is negotiated (see SSLEnabledProtocols), only the following cipher suites are supported:
- TLS_AES_256_GCM_SHA384
- TLS_CHACHA20_POLY1305_SHA256
- TLS_AES_128_GCM_SHA256
SSLEnabledCipherSuites is used together with SSLCipherStrength.
Not all supported protocols are enabled by default. The default value is 4032 for client components, and 3072 for server components. To specify a combination of enabled protocol versions set this config to the binary OR of one or more of the following values:
TLS1.3 | 12288 (Hex 3000) |
TLS1.2 | 3072 (Hex C00) (Default - Client and Server) |
TLS1.1 | 768 (Hex 300) (Default - Client) |
TLS1 | 192 (Hex C0) (Default - Client) |
SSL3 | 48 (Hex 30) |
SSL2 | 12 (Hex 0C) |
Note that only TLS 1.2 is enabled for server components that accept incoming connections. This adheres to industry standards to ensure a secure connection. Client components enable TLS 1.0, TLS 1.1, and TLS 1.2 by default and will negotiate the highest mutually supported version when connecting to a server, which should be TLS 1.2 in most cases.
SSLEnabledProtocols: Transport Layer Security (TLS) 1.3 Notes:
By default when TLS 1.3 is enabled, the control will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.
In editions that are designed to run on Windows, SSLProvider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is supported only on Windows 11/Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.
If set to 1 (Platform provider), please be aware of the following notes:
- The platform provider is available only on Windows 11/Windows Server 2022 and up.
- SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
- If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2, these restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.
SSLEnabledProtocols: SSL2 and SSL3 Notes:
SSL 2.0 and 3.0 are not supported by the control when the SSLProvider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider needs to be set to platform.
This configuration setting is applicable only when SSLProvider is set to Internal.
If set to True, all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.
When set, the control will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools, such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffic for debugging purposes. When writing to this file, the control will only append, it will not overwrite previous values.
Note: This configuration setting is applicable only when SSLProvider is set to Internal.
Note: For server components (e.g., TCPServer), this is a per-connection configuration setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedCipher[connId]");

This functionality is currently not available when the provider is OpenSSL.
The value of this configuration setting is a newline-separated (CR/LF) list of certificates. For instance:
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... Intermediate Cert... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp ...

When specified the control will verify that the server certificate signature algorithm is among the values specified in this configuration setting. If the server certificate signature algorithm is unsupported, the control fails with an error.
The format of this value is a comma-separated list of hash-signature combinations. For instance:
component.SSLProvider = TCPClientSSLProviders.sslpInternal;
component.Config("SSLEnabledProtocols=3072"); //TLS 1.2
component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa");
The default value for this configuration setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.
To not restrict the server's certificate signature algorithm, specify an empty string as the value for this configuration setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.
The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.
When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1" (default)
The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result, only some groups are included by default in this configuration setting.
Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used that is not present in this list, it will incur an additional roundtrip and time to generate the key share for that group.
In most cases, this configuration setting does not need to be modified. This should be modified only if there is a specific reason to do so.
The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072
The values are ordered from most preferred to least preferred. The following values are supported:
