Mu. It depends on what you want to do and from which angle you look at 
it. Quite often process A creates a child window in its window and 
passes the ID of the child to process B, which creates a grandchild 
exactly covering the child, and operates the grandchild. But sometimes 
you really want to draw in someone else's window.
