Chatting application

[Mooz]

How can I make a chatting application to talk with people on a private network, I want to use C or C#.

This can be done through the operating system's interface that it provides towards the network stack.

On Windows, you use Winsock (aka, Windows Sockets).
On Linux/*nix - you use Unix Sockets.

Establish a protocol that's relatively sane and secure, in network byte order.
Define your TCP/IP (or UDP) structures for the address, bind a server, connect a client.
...
???
Profit.
