How to override OnEraseBkgnd of a transparent window?
Posted on 1998-12-07
When I make a window transparent(WS_EX_TRANSPARENT or simply return true in OnEraseBkgnd), it doesn't refresh its client area after moved (the transparent part always look the same).
Is it needed to implement something in OnEraseBkgnd() to do
so? plz give me an example. Thanks.
