Help me figure out how to get XMPP working programmatically (see desc)

I can connect to the chat server via iChat/Jabber but for some reason I just CANNOT connect using the same details programmatically (vb.net). I am looking for someone who can show me how to connect to this specific chat server programatically. I can show you how I connect using the iChat client and prove that connection is possible. I\'ve tried numerous libraries for xmpp but I wasn\'t able to get anywhere with it. I would require the source once we\'ve accomplished this. Sorry if this seems a little vague. I can provide you with the chat server, port, etc and show you how to connect via jabber in iChat then hopefully you can code something in vb.net that will allow me to connect that way.
