ICMP Component
Properties Methods Events Config Settings Errors
The ICMP component is used to facilitate ICMP communications. It can act both as a client and a server and can communicate with any number of hosts simultaneously. It also can generate and receive broadcast packets.
Syntax
nsoftware.IPWorks.Icmp
Remarks
The interface of the component is similar to the interface of TCPClient, only it is much simpler. The component is activated/deactivated by using the Active property. This property enables or disables the sending or receiving of data. Data can be sent in the same way as TCPClient, using the Send method and Text parameter or the DataToSend property. The destination is specified using the RemoteHost property. The component automatically creates an ICMP header containing MessageType, MessageSubType, and a checksum for the message.
If the UseConnection configuration setting is set to True, then a local association is created with the remote host. Otherwise, the component can receive datagrams (packets) from any host and can send datagrams to any host. Packets can be broadcast on the local net by setting the destination to 255.255.255.255.
Inbound data is received through the DataIn event.
The operation of the component is almost completely asynchronous. All the calls, except the ones that deal with domain name resolution, operate through Windows messages (no blocking calls). The gain in performance is considerable when compared with using blocking calls.

AcceptData Property (ICMP Component)
This property enables or disables data reception (the DataIn event).
Syntax
Default Value
True
Remarks
This property enables or disables data reception (the DataIn event). Setting this property to False, temporarily disables data reception (and the DataIn event). Setting this property to True, reenables data reception.
Note: It is recommended to use the PauseData or ProcessData method instead of setting this property.
This property is not available at design time.
Active Property (ICMP Component)
This property indicates whether the component is active.
Syntax
Default Value
False
Remarks
This property indicates whether the component is currently active and can send or receive data.
If the UseConnection configuration setting is set to True, then a local association (connection) to the remote host also is created.
Note: Use the Activate or Deactivate method to control whether the component is active.
This property is not available at design time.
DataToSend Property (ICMP Component)
This write-only property includes a string of data to be sent to the remote host.
Syntax
Default Value
""
Remarks
This property is write-only and contains a string of data to be sent to the remote host. Assigning a string to this property makes the component send the string to the remote host. The Send method provides similar functionality.
The Transmission Control Protocol (TCP)/IP subsystem attempts to send the string assigned to this property as a complete message. If socket buffers are full, or if the message cannot be delivered for any other reason, an error is fired, and no portion of the message is sent. This is different from TCP in which case portions of the messages can be sent. ICMP sends either a complete message or nothing at all.
If you are sending data to the remote host faster than it can process it, or faster than the network's bandwidth allows, the outgoing queue might fill up. When this happens, DataToSend fails with exception 10035: "[10035] Operation would block" (WSAEWOULDBLOCK). You can check this error, and then try to send the data again. .
This property is write-only and not available at design time.
DontRoute Property (ICMP Component)
If this property is set to True, it forces the socket to send data directly to the interface (no routing).
Syntax
Default Value
False
Remarks
If this property is set to True, it forces the socket to send data directly to the interface (no routing). Normally, IP sockets send packets of data through routers and gateways until they reach the final destination. If this property is set to True, then data will be delivered on the local subnet only.
This property is not available at design time.
LocalHost Property (ICMP Component)
The name of the local host or user-assigned IP interface through which connections are initiated or accepted.
Syntax
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 multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.
If the component 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 multi-homed 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.
MessageSubType Property (ICMP Component)
This property is the subtype of the ICMP message (part of the ICMP header).
Syntax
Default Value
0
Remarks
This property contains the subtype of the ICMP message (part of the ICMP header). The ICMP message subtype (also referred to as "code") is a byte value representing the message subclass. Its meaning is associated with the MessageType.
Types and subtypes of ICMP messages are defined in the various internet RFCs and other documentation associated with Transmission Control Protocol (TCP)/IP.
MessageType Property (ICMP Component)
This property includes the type of the ICMP message (part of the ICMP header).
Syntax
Default Value
0
Remarks
This property contains the type of the ICMP message (part of the ICMP header). The ICMP message type is a byte value representing the message class. The message type defines the structure and meaning of the message data assigned to DataToSend.
Types for ICMP messages are defined in the various internet RFCs and other documentation associated with Transmission Control Protocol (TCP/IP). The following are a few examples of ICMP message types:
0 | Echo reply ("ping" reply). |
3 | Destination unreachable. |
4 | Source quench. |
5 | Redirect (change a route). |
8 | Echo request ("ping" request). |
11 | Time exceeded for datagram. |
12 | Parameter problem on datagram. |
13 | Timestamp request. |
14 | Timestamp reply. |
17 | Address mask request. |
18 | Address mask reply. |
RemoteHost Property (ICMP Component)
This property includes the address of the RemoteHost. Domain names are resolved to IP addresses.
Syntax
Default Value
""
Remarks
This property specifies the IP address (IP number in dotted internet format) or the domain name of the remote host.
If this property is set to 255.255.255.255, the component broadcasts data on the local subnet.
If this property is set to a domain name, a DNS request is initiated. Upon successful termination of the request, the property is set to the corresponding address. If the search is not successful, the component throws an exception.
If UseConnection is True, this property must be set before the component is activated (Active is set to True).
Timeout Property (ICMP Component)
A timeout for the component.
Syntax
Default Value
0
Remarks
If the Timeout property is set to 0, all operations return immediately, potentially failing with an 'WOULDBLOCK' error if data can't be sent or received immediately.
If Timeout is set to a positive value, the component will automatically retry each operation that would otherwise result in a 'WOULDBLOCK' error for a maximum of Timeout seconds.
The component 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 component throws an exception.
Please note that by default, all timeouts are inactivity timeouts, i.e. 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 0 (asynchronous operation).
Note: when a communication component behaves asynchronously in .NET, some events can fire from the background threads used to process socket IO. This can cause problems in GUI applications where there is logic inside an asynchronous event that interacts with the GUI. In .NET, most GUI controls will not allow themselves to be accessed from any thread other than the one that created them due to potential deadlocking issues. To ensure the user can do this, the .NET GUI API supplies a BeginInvoke method that can be used to access GUI controls from other threads, such as the ones that fire events. You can also set the InvokeThrough property of the communication component to any control on the GUI form to direct the component to forward all events through that control.
TimeToLive Property (ICMP Component)
This property includes the time-to-live (TTL) value for the ICMP packets sent by the component.
Syntax
Default Value
0
Remarks
This method contains the time-to-live (TTL) value for the ICMP packets sent by the component. The TTL field of the ICMP packet is a counter limiting the lifetime of a packet.
Each router (or other module) that handles a packet decrements the TTL field by one or more if it holds the packet for more than one second. Thus, the TTL value is effectively a hop count limit on how far a datagram can propagate through the internet. When the TTL value is reduced to zero (or less), the packet is discarded.
If the value of the property is set to zero, then the default TTL value of the underlying Transmission Control Protocol (TCP)/IP subsystem will be used.
This property is not available at design time.
Activate Method (ICMP Component)
This method enables sending and receiving of data.
Syntax
public void Activate(); Async Version public async Task Activate(); public async Task Activate(CancellationToken cancellationToken);
Public Sub Activate() Async Version Public Sub Activate() As Task Public Sub Activate(cancellationToken As CancellationToken) As Task
Remarks
This method enables sending and receiving of data. When called, the component will create a communication endpoint (socket) that can be used for sending and receiving ICMP messages. This method must be called before using the component to send and receive data.
If the UseConnection configuration setting is set to true, then a local association (connection) to the remote host also is created.
Config Method (ICMP Component)
Sets or retrieves a configuration setting.
Syntax
Remarks
Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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.
Deactivate Method (ICMP Component)
This method disables sending and receiving of data.
Syntax
public void Deactivate(); Async Version public async Task Deactivate(); public async Task Deactivate(CancellationToken cancellationToken);
Public Sub Deactivate() Async Version Public Sub Deactivate() As Task Public Sub Deactivate(cancellationToken As CancellationToken) As Task
Remarks
This method disables sending and receiving of data. When called, the component will destroy the existing socket and disable data communications.
DoEvents Method (ICMP Component)
Processes events from the internal message queue.
Syntax
public void DoEvents(); Async Version public async Task DoEvents(); public async Task DoEvents(CancellationToken cancellationToken);
Public Sub DoEvents() Async Version Public Sub DoEvents() As Task Public Sub DoEvents(cancellationToken As CancellationToken) As Task
Remarks
When DoEvents is called, the component processes any available events. If no events are available, it waits for a preset period of time, and then returns.
PauseData Method (ICMP Component)
This method pauses data reception.
Syntax
public void PauseData(); Async Version public async Task PauseData(); public async Task PauseData(CancellationToken cancellationToken);
Public Sub PauseData() Async Version Public Sub PauseData() As Task Public Sub PauseData(cancellationToken As CancellationToken) As Task
Remarks
This method pauses data reception when called. While data reception is paused, the DataIn event will not fire. Call ProcessData to reenable data reception.
ProcessData Method (ICMP Component)
This method reenables data reception after a call to PauseData
Syntax
public void ProcessData(); Async Version public async Task ProcessData(); public async Task ProcessData(CancellationToken cancellationToken);
Public Sub ProcessData() Async Version Public Sub ProcessData() As Task Public Sub ProcessData(cancellationToken As CancellationToken) As Task
Remarks
This method reenables data reception after a previous call to PauseData. When PauseData is called, the DataIn event will not fire. To reenable data reception and allow DataIn to fire, call this method.
Note: This method is used only after previously calling PauseData. It does not need to be called to process incoming data by default.
Reset Method (ICMP Component)
Reset the component.
Syntax
public void Reset(); Async Version public async Task Reset(); public async Task Reset(CancellationToken cancellationToken);
Public Sub Reset() Async Version Public Sub Reset() As Task Public Sub Reset(cancellationToken As CancellationToken) As Task
Remarks
This method will reset the component's properties to their default values.
ResolveRemoteHost Method (ICMP Component)
Resolves the hostname in RemoteHost to an IP address.
Syntax
public void ResolveRemoteHost(); Async Version public async Task ResolveRemoteHost(); public async Task ResolveRemoteHost(CancellationToken cancellationToken);
Public Sub ResolveRemoteHost() Async Version Public Sub ResolveRemoteHost() As Task Public Sub ResolveRemoteHost(cancellationToken As CancellationToken) As Task
Remarks
This method resolves the hostname specified by RemoteHost to an IP address. The resolved value is available in the RemoteHost property after this method returns.
In most cases calling this method is not necessary, the component will resolve the hostname automatically when necessary. If DelayHostResolution is true this method may be called to manually resolve RemoteHost if desired.
Send Method (ICMP Component)
This method sends data to the remote host.
Syntax
public void Send(byte[] text); Async Version public async Task Send(byte[] text); public async Task Send(byte[] text, CancellationToken cancellationToken);
Public Sub Send(ByVal Text As String) Async Version Public Sub Send(ByVal Text As String) As Task Public Sub Send(ByVal Text As String, cancellationToken As CancellationToken) As Task
Remarks
This method sends data to the remote host. Calling this method is equivalent to setting the DataToSend property to Text.
SendBytes Method (ICMP Component)
This method sends data to the remote host.
Syntax
public void SendBytes(byte[] data); Async Version public async Task SendBytes(byte[] data); public async Task SendBytes(byte[] data, CancellationToken cancellationToken);
Public Sub SendBytes(ByVal Data As String) Async Version Public Sub SendBytes(ByVal Data As String) As Task Public Sub SendBytes(ByVal Data As String, cancellationToken As CancellationToken) As Task
Remarks
This method sends data to the remote host. Calling this method is equivalent to calling the SendBytes/SendText method.
SendText Method (ICMP Component)
This method sends data to the remote host.
Syntax
public void SendText(string text); Async Version public async Task SendText(string text); public async Task SendText(string text, CancellationToken cancellationToken);
Public Sub SendText(ByVal Text As String) Async Version Public Sub SendText(ByVal Text As String) As Task Public Sub SendText(ByVal Text As String, cancellationToken As CancellationToken) As Task
Remarks
This method sends data to the remote host. Calling this method is equivalent to calling the SendBytes/SendText method.
DataIn Event (ICMP Component)
This event is fired when a new ICMP messages come in.
Syntax
public event OnDataInHandler OnDataIn; public delegate void OnDataInHandler(object sender, IcmpDataInEventArgs e); public class IcmpDataInEventArgs : EventArgs { public int MessageType { get; } public int MessageSubType { get; } public string MessageData { get; }
public byte[] MessageDataB { get; } public int Checksum { get; } public string SourceAddress { get; } }
Public Event OnDataIn As OnDataInHandler Public Delegate Sub OnDataInHandler(sender As Object, e As IcmpDataInEventArgs) Public Class IcmpDataInEventArgs Inherits EventArgs Public ReadOnly Property MessageType As Integer Public ReadOnly Property MessageSubType As Integer Public ReadOnly Property MessageData As String
Public ReadOnly Property MessageDataB As Byte() Public ReadOnly Property Checksum As Integer Public ReadOnly Property SourceAddress As String End Class
Remarks
The MessageType parameter shows the type of the ICMP messages and the MessageSubType parameter shows its subtype.
The MessageData parameter contains the message data.
The Checksum parameter is True or False depending on the ICMP checksum validation on the message.
Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
Error Event (ICMP Component)
Fired when information is available about errors during data delivery.
Syntax
public event OnErrorHandler OnError; public delegate void OnErrorHandler(object sender, IcmpErrorEventArgs e); public class IcmpErrorEventArgs : EventArgs { public int ErrorCode { get; } public string Description { get; } }
Public Event OnError As OnErrorHandler Public Delegate Sub OnErrorHandler(sender As Object, e As IcmpErrorEventArgs) Public Class IcmpErrorEventArgs Inherits EventArgs Public ReadOnly Property ErrorCode As Integer Public ReadOnly Property Description As String End Class
Remarks
The Error event is fired in case of exceptional conditions during message processing. Normally the component throws an exception.
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.
ReadyToSend Event (ICMP Component)
Fired when the component is ready to send data.
Syntax
public event OnReadyToSendHandler OnReadyToSend; public delegate void OnReadyToSendHandler(object sender, IcmpReadyToSendEventArgs e); public class IcmpReadyToSendEventArgs : EventArgs { }
Public Event OnReadyToSend As OnReadyToSendHandler Public Delegate Sub OnReadyToSendHandler(sender As Object, e As IcmpReadyToSendEventArgs) Public Class IcmpReadyToSendEventArgs Inherits EventArgs End Class
Remarks
The ReadyToSend event indicates that the underlying TCP/IP subsystem is ready to accept data after a failed DataToSend.
Config Settings (ICMP Component)
The component 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 component, access to these internal properties is provided through the Config method.ICMP Config Settings
The default value is false for the default library and true for the Async library. The default value is false.
The default value is False.
The default value for IcmpDllTimeout is 60 seconds.
Note: This configuration setting is valid only when UseICMPDLL is set to True.
Each router (or other module) that handles a packet decrements the TTL field by one or more if it holds the packet for more than one second. Thus, the TTL is effectively a hop count limit on how far a datagram can propagate through the internet. When the TTL is reduced to zero (or less), the packet is discarded.
By default, the default TTL value of the underlying Transmission Control Protocol (TCP)/IP subsystem will be used.
Value | Description |
-1 (default) | The socket option is left unspecified. |
0 | Do not receive all network traffic. |
1 | Receive all network traffic. This enables the promiscuous mode on the network interface card (NIC). On a LAN segment with a network hub, a NIC that supports the promiscuous mode will capture all IPv4 or IPv6 traffic on the LAN, including traffic between other computers on the same LAN segment. |
2 | Receive only socket-level network traffic (this feature may not be implemented by your Windows installation). |
3 | Receive only IP-level network traffic. This option does not enable the promiscuous mode on the NIC. This option affects packet processing only at the IP level. The NIC still receives only those packets directed to its configured unicast and multicast addresses. A socket with this option enabled, however, not only will receive packets directed to specific IP addresses, but also will receive all the IPv4 or IPv6 packets the NIC receives. |
Note: This setting is valid only when UseICMPDLL is set to True.
The default value for this setting is False.
Note: If both this and UseICMPDLL are enabled, the iphlpapi.dll will take precedence.
0 | IPv4 Only |
1 | IPv6 Only |
2 | IPv6 with IPv4 fallback |
Socket Config Settings
Note: This option is not valid for UDP ports.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
Base Config Settings
In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the component does not attempt to process external events.
- Product: The product the license is for.
- Product Key: The key the license was generated from.
- License Source: Where the license was found (e.g., RuntimeLicense, License File).
- License Type: The type of license installed (e.g., Royalty Free, Single Server).
- Last Valid Build: The last valid build number for which the license will work.
This setting only works on these components: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.
Setting this configuration setting to true tells the component to use the internal implementation instead of using the system security libraries.
On Windows, this setting is set to false by default. On Linux/macOS, this setting is set to true by default.
If using the .NET Standard Library, this setting will be true on all platforms. The .NET Standard library does not support using the system security libraries.
Note: This setting is static. The value set is applicable to all components used in the application.
When this value is set, the product's system dynamic link library (DLL) is no longer required as a reference, as all unmanaged code is stored in that file.
