Question

I’m building an app that given another app mainWindowhandle it collects information about the window state. I have no problem collecting information about child windows, but I can not access the other open windows of an application or even the menus. Is there any way of getting all window handles of an application?

Answer 1

You could do what Process.MainWindowHandle appears to do: use P/Invoke to call the EnumWindows function, which invokes a callback method for every top-level window in the system.

In your callback, call GetWindowThreadProcessId, and compare the window’s process id with Process.Id; if the process ids match, add the window handle to a list.
