server <-> multiple clients (vb.net vs2k5)

Hello! I am new to the tcplistener & socket classes.

I am trying to setup a server application, that listens on port 10000 and can accept datastreams from multiple clients. I will be coding the client application as well.

Basically, all clients will be sending a string every 3 seconds or so. When the string arrives at the server, I want the server to add the string to a listbox.

Will I need to use sockets for this application? Or, will a tcplistener be sufficient? Also, if anyone has a tip or two to get started, I would appreciate it! I will read anything recommended. thanks!!!
