Windows | Application proxy
I am trying to learn myself how to program in C++. Now (I think) I have reached the chapter of making an application proxy.
I've been searching google for some days now but yet I haven't found anything.
With an application proxy I mean a program that can, for example, imitate an MSN conversation by sending the data of "Blah says: hiho" to the other computer.
I know this explanation isn't too clear, but I guess most people will understand what I mean anyway.
So my question is: How do I do this, can anyone link me to some good tutorials about it, or tell me where to look?
Thanks in advance,
