Ok can anybody tell me some good books from where i can learn about udp broadcasting or any web tutorial. I dream so I do.

Thank you very much for the help. ;) May I ask you one more favour, could you please give me the server code aswell. Thanks again.:cool: I dream so I do.

Yes, that's exactly what I want to do, but I donot know how to implement. Could you please help me with code. Thanks. I dream so I do.

This might be a very trivial question for most of you. I want to know how to write a program in vc++ for scanning a particular port on the lan. I have written a chat program, I want that whenever a user starts the client, it scans the network and finds the ip for connecting, if no server is found it will become a server. Most messengers do the same thing I suppose. Thanks in advance. I dream so I do.
