System.Net.Sock ets & Winsock 6

[Björn Pedersen]

I'm having a tough time getting System.Net.Sock ets to work with a server
that's based around Winsock 6.0. For many reasons I can't write a new server
because the server handles a number of client formats.

I'm writing a new client that should be able to connect to the Winsock-based
server. However, I can't get them to talk to each other. The server hears
and understands what System.Net.Sock ets is saying, but when it tries to
respond System.Net.Sock ets just acknowledges the connection.

Whatever I do (tcpClient, Socket, bufferbased or streambased) the app that
uses the socket-class just reports that the connection is just a mere
connection but that there is no data availible.

----
Dim tcpListen as New TcpListener(133 01)
Dim client As Socket
----
Private Sub PollTimer_Elaps ed(ByVal sender As System.Object, ByVal e As
System.Timers.E lapsedEventArgs ) Handles PollTimer.Elaps ed

Dim datBytes() As Byte

Dim datStr As String

Dim numBytes As Integer

Try

If tcpListen.Pendi ng = True Then

client = tcpListen.Accep tSocket

If client.Poll(1, SelectMode.Sele ctRead) = True Then

numBytes = client.Availabl e

client.Receive( datBytes)

End If

End If

client.Close()

Catch exc As Exception

Console.WriteLi ne(exc.Message)

Console.WriteLi ne(exc.StackTra ce)

Console.WriteLi ne(exc.TargetSi te)

Console.WriteLi ne(exc.GetType)

End Try

End Sub
