Messanger Plus is made in C++, right? But do they do it. Which include/header-file do they use..?

I'm developing C++ to, and I'm looking for some header-files for doing this. Where can I get a such file?

Thanks

It's a little more complex than just having a few header files laying around.

I recommend you start from the ground up. Start with a few simple programs, say an ASCII to Character converter, to get used to C++ and Windows, then move onto bigger things.
You will also want the latest version of the Microsoft SDK

Plus! actually injects a dll into the Process of MSN Messenger to call internal commands since it is very hard to code on the Messenger API in Windows XP since most of the API is referenced to Windows Messenger.

Ok.. I know it's somthing like windowMessage(WM_WRITE,"richTextEdit","Hello!") or somthing...
Also, I don't want to create a new messanger-plus or somthing. I just want to know how to put some text into a window like the person you are chatting with...
That's a small code, isn't it?

you can find the hwnd of the DIRECTUIHWND and then sendkeys the cahracters you want to send and then send enter, but thats not a very good way to do it

Much better to find the hwnd of the convo window, then use Active Accessibility to get to the text input area, and set its value property.

And it's not as easy as it sounds.
