Here are a few good links that I found helpful. I am actually working on this myself over the last few weeks and it is tough sometimes finding clear information.

The best site I found for Windows Sockets is actually MSDN, they give you a walkthrough of an application to help you out: http://msdn.microsoft.com/library/de...th_winsock.asp

The above link is mainly for Windows, Unix is similar in concept but uses some slightly different structures. Of course this is all in C++.

I also found this link helpful:
http://www.codeproject.com/useritems...ingtcp_cpp.asp

This one has a Unix and Windows Example:

Now, for the fun part. Although all of these links and tutorials will give you a good overview and give you a actual working program, the commenting on them are so-so at best. I actually took the www.codeproject.com tutorial listed above , and used the MSDN site to reference each and every class and function. I have revised and commented my version with tons of notes to make it more understandable.

I an now working on making the authors version even better, using more of the funtionallity, i am learning alot from doing it this way.

Hope this helps.

*PS: I have spent tons of money on books, and really do enjoy them, after finding that the "good stuff" is always a google away I now spend my time on that. You can usually find what your looking for pretty quick.
