David Wilkinso #2 / 3	Problem to refresh modeless dialog Cheickna: IMO, it is much easier to do long processing in a worker thread. That way, the main thread can handle all the GUI, and in particular update itself if it is covered and uncovered.

Robert Quir #3 / 3	Problem to refresh modeless dialog Well you should get a WM_PAINT for your dialog when the covering window is closed so do an UpdateData(FALSE) in your WM_PAINT handler.
