Add/Attach Button to program? Set parent?

[triumphost]

K I just got this Idea that I want to implement into a program I downloaded. Yes the program is open source but I dont wanna compile it, I just want to sort of Inject?..

What I want to do is add a button to the program and have the button execute my own code without affecting itself..

I was thinking of making a program with a button and then setting the parent to the one I downloaded but then realized that my program will still be running.

If possible I would also like to resize the buttons that already exist on the program to make space for my own..

Does anyone have any idea how to go about this?? I dont need source code I just need to know how. If u do have source code then thats fine and always a plus but its not "NEEDED".

How do you expect to accomplish the goals you posted if you don't recompile the program???? :icon_eek:

The above works for me so far.. It finds the window, Adds a button to it.. When the button is clicked, it does stuff.

How do I get it to detect when the window the button is on gets closed?? Like if the window with the button is closed, Then terminate my program.

P.S. I know guys :( I tried it with compiling the source but it just wont compile... I had to use Mingw32 and it kept saying Build Main [Error 1] or something like that.. And I just got tired of it so I thought u know, maybe there is a way? I tried ResHack but it doesnt detect the program properly.. so yeah.. the above is my only solution. Thank you for the replies. At least you replied unlike the other Load of ppl that saw the thread and couldnt even say that its impossible. So I appreciate the replies.. Any reply as long as it tells me something.

So is there a way to get my program to detect when the other program is closed?? And where do I add it?? I tried, I really did.. I put a do while loop but it kept not responding!
