Interprocess communication with a third-party DLL

[aldente]

Hello!

There is a DLL (ActiveX Plugin for MSIE) which does some nice stuff. I analyzed it, found some places inside where the values I'm interested in are available (e.g. where they are PUSHed). My problem is now to access them not from inside the debugger but with my app.

I thought about putting an invisible edit-box and an invisible button into my app and modify the DLL, so it does a SetWindowText with the interesting value (it's a string) and then sends a clicked-message to the button. The only problem is: I have just very, very little Assembly skills and I'm not able to implement that (and FindWindowEx and everything I would also need).

So is there any EASIER way to send this string to my app, or is there any good tutorial on how to add this message-stuff to a third-party DLL at Assembly-level?
