    Repaint screen?

    After painting to the screen's dc, how do I tell the screen dc to repaint itself so that what ever I drew will disappear?

    I tried the following, but it doesn't work:

    SendMessage HWND_BROADCAST, WM_PAINT, 0, 0

    Any help would be appreciated..

    InvalidateRect will do it. You will need the hwnd of the desktop though.

    Try this code, I got it from ALLAPI.net, a very usefull website!
    Code:
    Private Declare Function InvalidateRect Lib "user32" (ByVal hwnd As Long, lpRect As Long, ByVal bErase As Long) As Long

' This will repaint all windows and the desktop
InvalidateRect 0&, 0&, False
