| Exception | Description |
|---|---|
| InvalidOperationException | BeginXXX method used without providing an EndXXX event handler. |
Use this method if you wish to connect to a host transparently with minimal application impact, as execution occurs on another thread. This method begins to asynchronously connect to the server. Upon completion (on both success and failure) the EndConnect event is raised. An EventArgs object is passed into this event, containing information about the event. If the connection succeeds, the ConnectedChanged event is raised. Once the connection has been made, you can send and receive data from the remote device.
If you are using the Tcp component as a reference, you must "wire up" the event yourself. This involves creating a method as the event handler that implements the EventHandler delegate.
For more information on implementing and handling events using PowerTCP.NET, see the topic, Using Events In PowerTCP.
To connect synchronously, use the Connect method.
The following example demonstrates asynchronously connecting using the BeginConnect method.
[Visual Basic]
Private Sub Test()
' Begin to asynchronously connect to an echo port.
Tcp1.BeginConnect("atropos", 7)
End Sub
Private Sub Tcp1_EndConnect(ByVal sender As Object, ByVal e As ExceptionEventArgs) Handles Tcp1.EndConnect
' Connect complete, check for any exceptions
If e.Exception Is Nothing Then
' Now send some data.
Tcp1.Send("hello")
' Receive the data back.
Dim seg As Segment = Tcp1.Receive()
Debug.WriteLine(seg.ToString())
End If
End Sub
[C#]
private void Test()
{
// Begin to asynchronously connect to an echo port.
tcp1.BeginConnect("atropos", 7);
}
private void tcp1_EndConnect(object
sender, ExceptionEventArgs e)
{
// Connect complete, check for any exceptions
if(e.Exception == null)
{
// Now send some data.
tcp1.Send("hello");
// Receive the data back.
Segment seg = tcp1.Receive();
Debug.WriteLine(seg.ToString());
}
}
