VB Socket Programming...

[Paunchy]

Hey all,

Wondering if anyone can point me in the right direction to find some resources for socket programming using C++ or Visual Basic. I have a class coming up that's going to require some sort of program to be written that will include both a client and a server, and network programming is unfamiliar territory. Thanks in advance.

If you don't need the "raw" socket level, MSDN should have some example code for using wininet in C++ and the internet transfer control in VB.

For "real" sockets I found the bookTCP/IP Volume 3 (Windows sockets version) by Douglas Comer and David L. Stevens to be very helpful. It covers synch and asynch programming, TCP vs UDP sockets, etc. etc. The code is C++ but the book is about pseudocode and teaching concepts istead of being a Wrox-style pile o' code.

For specific protocols like HTTP, SMTP, POP, etc. the "RFC" documents from the W3C define what's supposted to happen and you should be able to find some source code by googling.

async sockets aren't platform compatible, so you basically have blocking and nonblocking sockets.
