Visual Basic Chat Area/Game Lobby

I'm a visual basic 6 programmer with somewhat limited experience. I have been working on a turn based strategy game for over a year and have a semi-working prototype. However, now I need to begin adding in online elements and I have no experience with this. I've been trying to work on making a chat room/game lobby that allows players to connect to a central server, chat, and then click on another player's name to begin a duel (1 on 1 game with the central server as the transfer and storage point for information). I made the lobby and chat room (there are lots of examples for this) but I'm having trouble getting the two players to be able to connect. I also need a foundation for sending/receiving data (variables and/or a method for activing events/data on the other client's machine). So, what I want is a way to connect two players (I can show you what I have if that helps...basically just mousing over a nickname in a list box and then clicking on "start duel" to begin a duel. But I'm having trouble sending data and I would just rather know what I'm doing wrong then keep trying fruitlessly. And then once this is accomplished a very simple framework/foundation for sending and receiving data using the winsock control (I would rather avoid api's) between two clients through a server with a turn based strategy game. For example, how would I have gameover = true sent to client 2 or how would I have a protocol for loading a form on client 2 after certain info is send from client 1. I just need some examples for each of these things. ## Deliverables 1)Two visual basic 6 projects. I need the source code and not the .exe. The first should be the client and the second the server. Inside the client project should be a fully functional chat room/game lobby (I have this already if it helps) and source code showing how to begin a duel (commented code). Also, some example code on sending data. Inside the server project should be source code on data the chat room/lobby and sending/receiving data. ## Platform It should run on Windows XP.
