Interprocess communication with a third-party DLL

[aldente]

OK, this Delphi line does exactly, what I want:

SetWindowText(FindWindowEx(FindWindow('TADCPwnd', nil), 0, 'TEdit', 'punkrock'), 'my tiny little value');

Quite a lame solution, but it works quite well. Plus the Edit-Box has an OnChange-event, so there is not even need for a button! Everything is done within this single line.
The values are all constants except "my tiny little value".

I looked in my debugger what this code looks like in Assembly language, result:

http://home.scarlet.be/~il095280/functioncall.gif (only ~ 4KB)

How to insert the function-calls to FindWindowExA and FindWindowA into the other program? Only SetWindowTextA is used on other locations in that program.


Please help me!
