Windows | Application proxy

Hello everyone.

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,
Eddie

You are probably looking for the MSN protocol. You'll also need a knowledge of socket programming a good place to start would be the stickied post in the networking forum.

I guess you misunderstood my question.

The MSN-thingy was just an example to show what I meant. I want to make a programm that can modify the data that get's sent to the the server from some program. This could be MSN, because I guess it sends something like "Blah says: Blahblah" to some port on the server (and probably lots more arguments, but it was just an example)

So, well, my question is mostly self-explaining. How can I send data to a server acting like I'm the client program.

O my god... I really don't know how to explain this... The way I always call it is "application proxy" but I don't know if that's the right word for it...

I hope someone can help me

Yours sincerely
Eddie
