Question

I have 3, and sometimes more duplicates of an executable, and what I would like to do is to reduce workforce by sharing mouse click and key press events through all applications, with C#.

I am able to get handle’s of executables, so ideas might be based on acquired handles.

Also I have done some work to ease my work, all applications are arranged at same coordinates, with the same window size. So basically transparent mouse and key clicks which will interact with all windows (the top window, as well as background windows) would do the trick.

Here you have how to do it:
