Retrieving window handlers of child processes

[darioars]

Hi guys!

I have programmed a C++ application containing calls to the function CreateProcess. These processes display windows on the screen but their sizes and positions are not the ones I prefer, so I decided to set them. In order to achieve it, I need HWND handlers, do any of you how to retrieve them?

Thanks a lot in advance!
Darío.

I did this a long time ago (5 years or more) and in C rather than C++.

My dim memory of this suggests that you need to search all the child windows of the Desltop window looking for the titles of your created windows and from that you can get the HWND and Post (never Send) the appropriate messages to them.

Hope this helps.

Yes, to do that you could call EnumWindows(), passing the address of an EnumWindowsProc() callback function. The callback is called for every top-level window, giving you the HWND of each. To retrieve the title call GetWindowText() using the HWND.

A better way, if you are writing those other programs too, would be to allow the desired window position and size to be passed to the program through the command line.
