mfc c++ set HWND address of another application through edit control

I know how to get and set the handle of another applications window in the code, but I don't know how to set the applications handle at runtime through an edit control. the problem is is that I have to keep compiling my application every time I want to use it, because the handle of the window in application 2 is dynamic.

does anyone have any ideas?

Solution

  • To find current HWND of application window you are interested in, you can enumareate windows using EnumWindows:

    or maybe easier is to use FindWindow, if you know its name/class:

    you can also use GetWindow to iterate windows:
