Socket listen

I Downloaded the socket example already but i don't get how to make a socket act like a server... Can someone help?

I beleive it is the Tcplistener class

Imports System.Net.Sockets

Dim svr As New TcpListener(port)


or something to that nature.....I saw one tiny example in the msdn help that came with VS .NET beta 2 a while back...just dont have it here at work to look it up.

i still have BETA 2 but i'm getting the final version. It would really like the example cause that's really what i need.
