Refreshing the Screen

[Federico Ceccatto]

Hi all

Is there a way to refresh/update regions of the screen that do not
belong to the application? I've drawn some fake "tooltips" with
ScreenDC but unless the application's maximized I'm leaving some
garbage on screen.

I could blit a previously stored bitmap but that does not ensure
consistency. Is there a way to do full or region-specific redrawing of
the screen?

Thanks for your time.
