A little help with WinSocks?

One of my students decided he wants to build a multiplayer networked game, and is writing it in VB.NET (2003). He’s been hunting down WinSock programming examples (and understanding very little of them) for a few days now, and (finally) turned to me for help.

Here’s the catch: I did some networked games a few years ago in VB6, but never managed to get the hang of it in VB.NET. I mean, it was blessedly easy back then: You plot the WinSock object on the form, and most of your work is done. I’ve periodically hunted for an equivalently simple example in .NET for a couple years, but never found one. (I even found something today in MSDN, but haven’t taken the time to translate it into English yet. 8^)

So then … are there any experts out there who know what I’m talking about, and can provide a quick tutorial or simple example of a socket based networked program? Even a generic "chat" program would get the basics across. (After all, a networked game is nothing more than a chat program that passes game status back and forth without actually telling the user what’s happening.)

Thanks in advance.

In the .net SDK, or at least the version that comes with Visual Studio, there’s a sample application WinTalk that demonstrated how to use the System.Net.Sockets namespace.

Thanks, I will look into it. (I figured there had to be something like this.)

Anyone know of an equivalent in VB.NET?

I haven’t looked at it yet but the videos at http://www.franklins.net/video/sockets/ may be useful.

Interesting. Took three tries of running the video on one computer whilst I typed at another, but I think the program works. Now, if only Carl actually explained in detail what the code did and why it works …

(I know, I’m asking a lot for nothing, ain’t I?)
