XMPP Control

Properties   Methods   Events   Config Settings   Errors  

The XMPP Control is used to create a lightweight messaging client using the XMPP (Jabber) protocol.

Syntax

XMPP

Remarks

The XMPP control supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. When connecting over Secure Sockets Layer/Transport Layer Security (SSL/TLS) the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL-related settings are also supported through the Config method.

A call to the ConnectTo method will perform the entire logon process after which a Connected event will fire to indicate the connection status. For simplicity, the entire interface is synchronous; the control will not return until a call is completed.

After a successful connection, the control will automatically begin the process of receiving the user's buddy list. The control will parse the XML as it comes in from the server and will set the appropriate properties. Once the entire buddy list has been retrieved, a Sync event will fire.

Sending a message is as simple as calling a single method. One call to the SendMessage method will cause the control to connect if it has not already done so, send the specified message to a specified user, and return to the original connection state.

The XMPP Control interface supports messaging, list, and presence management. Other features of the XMPP protocol are supported through the SendCommand method and PITrail event.

Example 1. Connecting and Sending a Message:

IMControl.ConnectTo("myusername", "mypassword") IMControl.MessageText = "My Message" IMControl.SendMessage("ToUser") Example 2. Sending a Single Message:

IMControl.User = "myusername" IMControl.Password = "mypassword" IMControl.MessageText = "My Message" IMControl.SendMessage("ToUser")

Remarks

When the control completes the initial login, it will send information telling other entities subscribed to this entity's presence that it is online.

The Presence property has one of four values representing general information about the user's status as defined in the Jabber protocol specification:

By default, the control sets the client presence to pcChat, meaning that the user is available.

Note: Offline is not officially supported by the XMPP specification; however, some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an Error.

The Status property is a pure-text string representing the user's presence information. Its value maybe be any random string, including the empty string, "".

If the application or user wishes to associate a specific status message with a new presence value, it should use the ChangePresence method. ChangePresence will update both the Presence and Status properties, and then send that information to the server.

String

SSLServerCertSubject Property (XMPP Control)

The subject of the certificate used for client authentication.

Syntax

xmppcontrol.SSLServerCertSubject

Default Value

""

Remarks

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.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma-separated list of distinguished name fields and values. For instance, "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are as follows:

If a field value contains a comma, it must be quoted.

This property is read-only.

Data Type

String

SSLServerCertEncoded Property (XMPP Control)

The certificate (PEM/Base64 encoded).

Syntax

xmppcontrol.SSLServerCertEncoded

Default Value

""

Remarks

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

SSLStartMode Property (XMPP Control)

This property determines how the control starts the Secure Sockets Layer (SSL) negotiation.

Possible Values

sslAutomatic(0), 
sslImplicit(1), 
sslExplicit(2), 
sslNone(3)

Default Value

3

Remarks

The SSLStartMode property may have one of the following values:

Data Type

Integer

Status Property (XMPP Control)

This property holds the description of the availability of this entity.

Syntax

xmppcontrol.Status

Default Value

"Available for Chat."

Remarks

When the control completes the initial login, it will send information telling other entities subscribed to this entity's presence that it is online.

The Presence property has one of four values representing general information about the user's status as defined in the Jabber protocol specification:

By default, the control sets the client presence to pcChat, meaning that the user is available.

Note: Offline is not officially supported by the XMPP specification; however, some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an Error.

The Status property is a pure-text string representing the user's presence information. Its value maybe be any random string, including the empty string, "".

If the application or user wishes to associate a specific status message with a new presence value, it should use the ChangePresence method. ChangePresence will update both the Presence and Status properties, and then send that information to the server.

This property is read-only and not available at design time.

Data Type

String

Timeout Property (XMPP Control)

The timeout for the control.

Syntax

xmppcontrol.Timeout[=integer]

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the control will wait for the operation to complete before returning control.

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 (XMPP Control)

This property includes the user portion of this entity's Jabber Id.

Syntax

xmppcontrol.User[=string]

Default Value

""

Remarks

The User property is a unique username associated with this entity and is set at the time of registration under the field "user".

Data Type

String

UserDomain Property (XMPP Control)

This property gets or sets the domain value used for Jabber Ids.

Syntax

xmppcontrol.UserDomain[=string]

Default Value

""

Remarks

A Jabber Id (JID) is a unique identifier of the format "User@Domain/Resource". user@domain denotes the account by username and domain. The Resource is given during the login process to distinguish individual connections under the same account. If the IMServer contains multiple domains, this property setting allows the user to specify the domain under which to log in.

If Domain is empty, the value in IMServer is used by default when creating the client's JID.

Data Type

String

UserInfoCount Property (XMPP Control)

The number of records in the UserInfo arrays.

Syntax

xmppcontrol.UserInfoCount[=integer]

Default Value

0

Remarks

This property controls the size of the following arrays:

• UserInfoField
• UserInfoValue

The array indices start at 0 and end at UserInfoCount - 1.

This property is not available at design time.

Data Type

Integer

UserInfoField Property (XMPP Control)

This property includes the name of the current property necessary for registration.

Syntax

xmppcontrol.UserInfoField(FieldIndex)[=string]

Default Value

""

Remarks

This property includes the name of the current property necessary for registration.

Before a registration can be attempted, the application should use the QueryRegister method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server and will populate the UserInfo properties accordingly. After a successful query, all entries in UserInfo values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification, as follows:

After the user has set all of the values in UserInfo, and added any extra fields they may wish to include in their registration, the application should make a call to Register.

If the control is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

The FieldIndex parameter specifies the index of the item in the array. The size of the array is controlled by the UserInfoCount property.

This property is not available at design time.

Data Type

String

UserInfoValue Property (XMPP Control)

This property includes the value of the current registration property.

Syntax

xmppcontrol.UserInfoValue(FieldIndex)[=string]

Default Value

""

Remarks

This property includes the value of the current registration field. It should be set after calling QueryRegister and before calling Register.

Before a registration can be attempted, the application should use the QueryRegister method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server and will populate the UserInfo properties accordingly. After a successful query, all entries in UserInfo values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification, as follows:

After the user has set all of the values in UserInfo, and added any extra fields they may wish to include in their registration, the application should make a call to Register.

If the control is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

The FieldIndex parameter specifies the index of the item in the array. The size of the array is controlled by the UserInfoCount property.

This property is not available at design time.

Data Type

String

Add Method (XMPP Control)

This method will add an entity to this entity's roster.

Syntax

xmppcontrol.Add JabberId, Name, Groups

Remarks

JabberId is the Jabber Id of the entity to be added. It should be of form "user@host". If no hostname is specified, the control will assume the user's account is with the server in IMServer, and will append that hostname to JabberId before sending the request.

Name will contain the name that is to be associated with JabberId in this entity's roster. It may be the empty string, "".

Groups is either the empty string ("") or a comma- separated list of groups to which the JabberId is to be added. If JabberId already exists in the buddy list, it will be updated to exist only in the specified groups. A buddy's group list can also be modified by the Buddies property.

The Add method will make a subscription request to the presence of the specified JabberId. Upon receiving this request, the server will add an entry into this user's buddy list with a subscription of type subscriptionNone (0) if there was no previous entry (if this user has already allowed JabberId to subscribe to this user's presence, there will already be an entry of type subscriptionFrom (2)). If the contact chooses to allow the subscription, the server will update the entry and a BuddyUpdate event will fire with the new subscription value (subscriptionTo (1) if this is a new contact, or subscriptionBoth (3) if the contact is now mutual).

The XMPP protocol permits XMPP (Jabber) clients to communicate with foreign IM networks, such as AIM, MSN, SMS, and others, through the use of gateway servers that translate between the foreign protocol and XMPP. When sending or receiving presence information, messages, or subscription requests, Domain will be a gateway for the foreign network on which the contact resides and with which this user has registered an account for that foreign network. The Register method can be used to register with a foreign network gateway.

Cancel Method (XMPP Control)

This method will cancel another entity's subscription to this entity's presence.

Syntax

xmppcontrol.Cancel JabberId

Remarks

If for any reason the user should want to undo a previously granted subscription, this can be achieved through the Cancel method. The method will unsubscribe the target from this user's presence, thus preventing the target from seeing this user in the future.

ChangePassword Method (XMPP Control)

This method will change the current user's password.

Syntax

xmppcontrol.ChangePassword Password

Remarks

This method changes the current user's password to the password that is specified. The control must be connected to the server when this method is called.

ChangePresence Method (XMPP Control)

This method will set the availability and status of this entity.

Syntax

xmppcontrol.ChangePresence PresenceCode, Status

Remarks

PresenceCode should correspond to the possible values of the Presence property:

By default, the control sets the client presence to pcChat, meaning that the user is available.

Note: Offline is not officially supported by the XMPP specification; however, some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an Error.

Status can be any random string, including the empty string "".

Config Method (XMPP Control)

Sets or retrieves a configuration setting.

Syntax

xmppcontrol.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 (XMPP Control)

This method will connect the control to the server.

Syntax

xmppcontrol.Connect 

Remarks

The Connect method performs the entire connection routine. This includes connection to the IMServer, authenticating with the specified User and Password, and session initialization.

The Connected event will fire once for the initial Transmission Control Protocol (TCP) connection and again when the XMPP Logon is complete.

ConnectTo Method (XMPP Control)

This method will connect the control to the server.

Syntax

xmppcontrol.ConnectTo User, Password

Remarks

The ConnectTo method performs the entire connection routine. This includes connection to the IMServer, user logon and authentication, and session initialization.

The Connected event will fire once for the initial Transmission Control Protocol (TCP) connection and again when the XMPP Logon is complete.

Because ConnectTo is called with a user and password specified, the User and Password properties will updated accordingly.

Disconnect Method (XMPP Control)

This method disconnects the control from the server.

Syntax

xmppcontrol.Disconnect 

Remarks

The Disconnect method will send the disconnect command to the notification server. Upon disconnection, a Disconnected event will be fired.

DoEvents Method (XMPP Control)

This method processes events from the internal message queue.

Syntax

xmppcontrol.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.

Interrupt Method (XMPP Control)

This method interrupts the current method.

Syntax

xmppcontrol.Interrupt 

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

ProbePresence Method (XMPP Control)

Use this method to probe for another entity's presence.

Syntax

xmppcontrol.ProbePresence JabberId

Remarks

In the case that the user needs to update a particular entity's presence, this method can be used to retrieve it. After a successful call, the server will either respond with the last known presence for Jabber or will send a presence element of type "error". In either case, the respond will be returned by a Presence event.

QueryRegister Method (XMPP Control)

This method queries a server for the necessary registration fields.

Syntax

xmppcontrol.QueryRegister XMPPServer

Remarks

Before a registration can be attempted, the application should use the QueryRegister method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server and will populate the UserInfo properties accordingly. After a successful query, all entries in UserInfo values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification, as follows:

After the user has set all of the values in UserInfo, and added any extra fields they may wish to include in their registration, the application should make a call to Register.

If the control is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

Register Method (XMPP Control)

This method registers an account with a server.

Syntax

xmppcontrol.Register XMPPServer

Remarks

Before a registration can be attempted, the application should use the QueryRegister method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server and will populate the UserInfo properties accordingly. After a successful query, all entries in UserInfo values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification, as follows:

After the user has set all of the values in UserInfo, and added any extra fields they may wish to include in their registration, the application should make a call to Register.

If the control is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

A new account can be registered at any time, including while the control is logged into the host under an existing account.

Remove Method (XMPP Control)

This method will remove an entity from this entity's roster.

Syntax

xmppcontrol.Remove JabberId, Name, Group

Remarks

JabberId is the Jabber Id of the entity to be removed. It should be in the form of "user@host". If no hostname is specified, the control will assume the user's account is with the server in IMServer, and it will append that hostname to JabberId before sending the request.

Name should contain the name that is to be associated with JabberId in this entity's roster. It may be the empty string, "".

Groups may be either the empty string ("") or a comma- separated list of groups from which JabberId is to be removed. If no group is specified, the buddy will be completely removed from the buddy list.

After calling the Remove method, the server will remove the entry from the server-side roster and will push the result out to all connected resources. A BuddyUpdate event will fire with a subscription of type subscriptionRemove, and the entry will be removed from the Jabber control's internally stored list.

Reset Method (XMPP Control)

This method will reset the control.

Syntax

xmppcontrol.Reset 

Remarks

This method will reset the control's properties to their default values.

RetrieveRoster Method (XMPP Control)

This method will retrieve this entity's roster from the server.

Syntax

xmppcontrol.RetrieveRoster 

Remarks

After the control connects, it will automatically send a request to the server to retrieve the roster. If, however, the user or application wish to update the entire roster, this method may be used to do so.

After a successful call to the RetrieveRoster method, the server will respond with this entity's roster. The control will parse the roster and fire the Sync event once per item. This event may also fire for each entity added to or removed from the roster.

SendCommand Method (XMPP Control)

This method sends a command to the server.

Syntax

xmppcontrol.SendCommand Command

Remarks

The SendCommand method will send the Command parameter to the server. The command must be in valid XML format and must be recognizable to the IMServer.

The SendCommand method should be used only by programmers or users who are connecting to nonstandard servers whose command list is not covered by the control. Any responses that are defined in the protocol specification will be returned by the appropriate event. Any nonstandard IQ message will be returned by the IQ event. All other responses will be returned by the PITrail event.

SendFile Method (XMPP Control)

This method sends a file to the specified user.

Syntax

xmppcontrol.SendFile JabberId

Remarks

This method sends the file specified by LocalFile to the user specified by the JabberId parameter.

JabberId is the intended recipient of the message. It is of the form user@domain/resource. If a resource is not supplied, all logged-in instances of the user's account will receive the message.

The control supports sending files using In-Band Bystestreams as defined in XEP-0047 and XEP-0096.

SendMessage Method (XMPP Control)

This method will send a message to the specified user.

Syntax

xmppcontrol.SendMessage JabberId

Remarks

JabberId is the intended recipient of the message. It is of the form user@domain/resource. If a resource is not supplied, all logged-in instances of the user's account will receive the message.

The control associates several properties with messages it receives and sends. When it receives a message, the control will parse out the corresponding values and set these properties before firing a MessageIn event. After the event returns control to the control, the properties will be cleared (i.e., they will be set to the empty string, "").

Before sending a message, the application should set the appropriate properties to be associated with the message. The control will send only properties with nonempty string values ("") and will clear all properties after a successful send.

The associated properties are the following:

If the parameter passed to SendMessage is prefixed with "@" the component will interpret the value as a domain when constructing the message. This allows for sending directly to subdomains.

Note: The XMPP control will generate and return a unique identifier for each message sent. This identifier can be used to track messages in conjunction with various Jabber Extension Protocols.

SetUserInfoField Method (XMPP Control)

This method will add a user information field for registration.

Syntax

xmppcontrol.SetUserInfoField Field, Value

Remarks

This method will search through UserInfo for the field name in Field and set the corresponding value to Value. If the field was not previously contained in UserInfo, it will automatically be added.

Before a registration can be attempted, the application should use the QueryRegister method to poll the host to which the user wishes to register. This will gather all of the necessary fields that the user must send to the server and will populate the UserInfo properties accordingly. After a successful query, all entries in UserInfo values will be empty strings.

The possible registration fields are defined in the Jabber protocol specification, as follows:

After the user has set all of the values in UserInfo, and added any extra fields they may wish to include in their registration, the application should make a call to Register.

If the control is not already connected when this method is called, it will connect, poll the registration fields, and then disconnect.

SubscribeTo Method (XMPP Control)

Use this method to subscribe to another entity's presence.

Syntax

xmppcontrol.SubscribeTo JabberId

Remarks

This method will send a request for a subscription to JabberId's presence. If the entity allows the subscription, a new item will be stored in the buddy list with the appropriate subscription type. Otherwise, no change will take place.

Unregister Method (XMPP Control)

This method cancels an account with the host.

Syntax

xmppcontrol.Unregister 

Remarks

If the user or application wishes to terminate an account with the IMServer it should make a call to this method. After a successful call, the account will be canceled and the control will be logged off the server, but not disconnected.

UnsubscribeTo Method (XMPP Control)

This method will cancel a subscription to another entity's presence.

Syntax

xmppcontrol.UnsubscribeTo JabberId

Remarks

This method will inform the server of the cancellation of a subscription to JabberId's presence. After a successful call, the subscription type of the associated buddy list item will be updated.

UpdateBuddyGroup Method (XMPP Control)

This method updates the buddy's associated groups.

Syntax

xmppcontrol.UpdateBuddyGroup BuddyIndex, Group

Remarks

This method updates the associated groups for the buddy specified by BuddyIndex.

After the Sync event has fired, the BuddyGroup property is populated with a comma-separated list of groups for each buddy. To update the groups for a buddy, call this method with the buddy's index and the comma-separated list of groups the buddy should be associated with. Setting Group to an empty string ("") will cause the buddy to be completely disassociated from all groups.

BuddyUpdate Event (XMPP Control)

This event is fired whenever a roster entry is updated.

Syntax

Sub xmppcontrol_BuddyUpdate(BuddyIdx As Integer)

Remarks

The BuddyUpdate event will fire whenever a new buddy list entry is added or an old entry is updated. The updated information can be retrieved through the Buddies properties property. The BuddyIdx parameter of this event will be the index of that XMPPBuddy in the properties.

Connected Event (XMPP Control)

This event is fired when a connection to the IM server is completed.

Syntax

Sub xmppcontrol_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 (XMPP Control)

Fired to indicate changes in the connection state.

Syntax

Sub xmppcontrol_ConnectionStatus(ConnectionEvent As String, StatusCode As Integer, Description As String)

Remarks

This 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:

Disconnected Event (XMPP Control)

This event is fired when the chat service connection is lost.

Syntax

Sub xmppcontrol_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.

EndTransfer Event (XMPP Control)

This event is fired when a file transfer completes.

Syntax

Sub xmppcontrol_EndTransfer(Direction As Integer, FileId As String, FileName As String, Success As Boolean)

Remarks

When a file transfer completes, this event will fire.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Error Event (XMPP Control)

This event is fired when the server sends a protocol error message.

Syntax

Sub xmppcontrol_Error(ErrorCode As Integer, Description As String)

Remarks

This event is fired whenever there is a protocol error. ErrorCode will contain the error code string sent by the server. Description will contain the Xmpp control's interpretation of the code.

IQ Event (XMPP Control)

This event is fired for IQ messages not normally supported by the control.

Syntax

Sub xmppcontrol_IQ(Iq As String, Id As String, From As String, IqType As String, Ignore As Boolean)

Remarks

Some servers may wish to gather some data from the client in ways not specified by the XMPP RFC. This event will contain any IQ message that is not a part of the Jabber specification. The Iq parameter will contain an entire XML entity, and thus it will require both knowledge of XML and knowledge of the possible contents of the IQ message to parse. Id will contain the transaction Id of the IQ message. From will contain the sender's Jabber Id. IqType will have one of the following values:

Note: To respond to these IQs, you may use the SendCommand method.

MessageIn Event (XMPP Control)

This event is fired upon receipt of a message.

Syntax

Sub xmppcontrol_MessageIn(MessageId As String, From As String, Domain As String, Resource As String, MessageType As Integer, Subject As String, MessageThread As String, MessageText As String, MessageHTML As String, Other As String)

Remarks

When a message is received, the XMPP control will parse the sender's Jabber Id into the From, Domain, and Resource fields. These parameters can be used to track the exact instance of a user's account that originated the message.

MessageId can be used with Jabber extension protocols. The MessageText parameter is the plaintext portion of the message body. MessageHTML will contain any HTML from the message.

Type is the type of message received. See MessageType for a list of possible values. For a message of type "headline", Subject will reflect the subject of the message. For a message of type "chat", Thread will report the conversation thread for which the current message is a follow-up.

Other will contain any extra data associated with the message but not defined by the XMPP-IM protocol.

PITrail Event (XMPP Control)

This event is fired for all protocol messages.

Syntax

Sub xmppcontrol_PITrail(Direction As Integer, Pi As String)

Remarks

The PITrail event is useful for debugging purposes. It shows all the interactions between the client and the server, line by line.

SessionId will hold the session number that originated the PI. A value of 0 is reserved for all PI dealing with the IMServer.

The direction parameter shows the originator of the message:

The Pi parameter contains the PI message.

Presence Event (XMPP Control)

This event is fired when the presence of a subscribed entity changes.

Syntax

Sub xmppcontrol_Presence(User As String, Domain As String, Resource As String, Availability As Integer, Status As String)

Remarks

This event contains the availability and status information of a particular Jabber entity to whom this entity has a subscription.

Because a user can log in multiple times using the same account, the XMPP control will parse the user's Jabber Id into the User, Domain, and Resource parameters so that the client can easily track which instance of the account sent the presence.

The XMPP protocol permits XMPP (Jabber) clients to communicate with foreign IM networks, such as AIM, MSN, SMS, and others, through the use of gateway servers that translate between the foreign protocol and XMPP. When sending or receiving presence information, messages, or subscription requests, Domain will be a gateway for the foreign network on which the contact resides and with which this user has registered an account for that foreign network. The Register method can be used to register with a foreign network gateway.

Availability corresponds to the Presence property of the control, with the same possible values:

By default, the control sets the client presence to pcChat, meaning that the user is available.

Note: Offline is not officially supported by the XMPP specification; however, some XMPP server implementations may recognize the value. Setting the client's presence state to this value may cause the server to respond with an Error.

Status corresponds to the Status property. This value may be any random string, including the empty string, "".

ReadyToSend Event (XMPP Control)

This event is fired when the control is ready to send data.

Syntax

Sub xmppcontrol_ReadyToSend()

Remarks

The ReadyToSend event indicates that the underlying Transmission Control Protocol (TCP)/IP subsystem is ready to accept data after a failed SendBytes. This event also is fired immediately after a connection to the remote host is established.

SSLServerAuthentication Event (XMPP Control)

Fired after the server presents its certificate to the client.

Syntax

Sub xmppcontrol_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 (XMPP Control)

Fired when secure connection progress messages are available.

Syntax

Sub xmppcontrol_SSLStatus(Message As String)

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

StartTransfer Event (XMPP Control)

This event is fired when a file transfer begins.

Syntax

Sub xmppcontrol_StartTransfer(Direction As Integer, FileId As String, User As String, Domain As String, Resource As String, FileName As String, Datetime As String, Size As Long64, Accept As Boolean)

Remarks

When a file is received, the XMPP component will parse the sender's Jabber Id into the User, Domain, and Resource fields. The FileId and FileName parameters identify the current transfer. Within this event, you may override the FileName by setting the FileName parameter. At this time, you may also set LocalDirectory if it is not already set.

When sending a file, the XMPP component will parse the receiver's Jabber Id into the User, Domain, and Resource fields.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

SubscriptionRequest Event (XMPP Control)

This event fires when a subscription request is received.

Syntax

Sub xmppcontrol_SubscriptionRequest(From As String, Domain As String, Accept As Boolean)

Remarks

This event fires whenever another XMPP entity requests a subscription to this entity's presence. The XMPP control will parse the requesting entity's Jabber Id into the From and Domain parameters. It is not necessary to know which resource sent the request, because all instances of the requesting entity's account have access to the same roster.

Accept will initially be False, but setting it to True will cause the XMPP control to allow the remote subscription. Otherwise, the XMPP control will actively deny the subscription request.

Sync Event (XMPP Control)

This event fires upon a complete information synchronization with the server.

Syntax

Sub xmppcontrol_Sync()

Remarks

The Sync event will fire after each successful call to the RetrieveRoster method. When the event fires, the buddy list, or roster, will be completely retrieved and the Buddies properties will be filled out accordingly:

Note: Please refer to Buddies properties property for more information.

Transfer Event (XMPP Control)

This event is fired during file transfer.

Syntax

Sub xmppcontrol_Transfer(Direction As Integer, FileId As String, FileName As String, BytesTransferred As Long64, PercentDone As Integer, Text As String, Cancel As Boolean)

Remarks

This event will fire when sending or receiving. One or more Transfer events are fired during file transfer.
