Programmatically press a button on another application (C, Windows)

Question

I\'m trying to use the following code to press a button on my other application:

HWND ButtonHandle;
if( (wnd = FindWindow(0, \"Do you want to save?\")) )
{   
           


        

Answer 1

1. Are you sure that "SaveButton" class name is valid? Do you get the button handle?
2. Try to send messages to ButtonHandle window (directly to the button).

Update: I believe this should work,

SendMessage(ButtonHandle, BM_CLICK, 0, 0);
