Hello, I want to make a program that have main MDI form and MDI-child documents.
I want to make a tree control with all the open document windows.
--what I like to know is how does the WindowList (menu with WindowsList checked) knowes all the open windows, and what in the unique property in each window.
If it's hWnd then how can i change or select the MDI-child window if i have his hWnd?

Thank you
Kiron
