High, how can i reach the (object sender) and its properties in an event. I´ve an Array of Tcp-Objects which all fire the same Events. Inside i need to know "who am i" as Tcp.Socket. The sender is it, how can i reach it inside the handle. For example sender.connected or sender.send() ...

private void AllTcp_ConnectedChanged(object sender, System.EventArgs e)
{
//Fires when Connection is established or closed
if (sender.Connected)
{}
}

This throuws a marshal-error. How do i get the Connection inside ConnectedChanged?

private void tcp1_ConnectedChanged(object sender, System.EventArgs e)
{
Dart.PowerTCP.Sockets.Tcp TCPsender = (Dart.PowerTCP.Sockets.Tcp)sender;

if (TCPsender.Connected){}

}

Please see the following thread where another customer was doing something similar:

In this Thread they use:

Private Sub Tcp_ConnectedChanged(ByVal sender As Object, ByVal e As EventArgs)
Dim s As Tcp = sender
Debug.WriteLine("CONNECTED CHANGED FIRED FOR INDEX " + s.Tag + "!")
End Sub

I think it is just the same i do in C#, but under Debug the sender is declared as {IOnetCOM.frmKommunikation} (my Form) not as {Dart.PowerTCP.Sockets.Tcp}as in other delegates.

Now i do somthing stupid but it works:
tcps[i] = new Dart.PowerTCP.Sockets.Tcp(this.components);
tcps[i].ConnectTimeout = 20000+i;
tcps[i].SynchronizingObject = this;
tcps[i].EndReceive += new Dart.PowerTCP.Sockets.SegmentEventHandler(this.tcp1_EndReceive);
tcps[i].EndConnect += new Dart.PowerTCP.Sockets.ConnectEventHandler(this.tcp1_EndConnect);
switch (i)
{
case 0 :
tcps[i].ConnectedChanged += new System.EventHandler(this.tcp0_ConnectedChanged);
break;
case 1 :
tcps[i].ConnectedChanged += new System.EventHandler(this.tcp1_ConnectedChanged);
break;
case 2 :
tcps[i].ConnectedChanged += new System.EventHandler(this.tcp2_ConnectedChanged);
break;
case 3 :
tcps[i].ConnectedChanged += new System.EventHandler(this.tcp3_ConnectedChanged);
break;
}
tcps[i].BeginConnect(cServer,49154);
