For our application we are looking at exchanging data between two computers in realtime, and I'm looking at using the ethernet to achieve this. I have done prorgamming with Visual C++ before, and am somewhat confident with it, but I've never done anything relating to network programming. Is there a step-by-step tutorial that I can find somewhere (book, internet) to get my started on this quickly, or maybe even a sample code?

Basically, it involves one computer to send out 5 numbers, each being a float or double, and the other computer receives these information in realtime, at the next cycle the first computer sents out another 5 numbers, and this process repeats until we tell the program to stop.

Many thanks in advance!
