    Win32API OnEraseBkgnd(CDC* pDC) equivalent?

    How to accomplish the "OnEraseBkgnd(CDC* pDC)" equivalent without MFC?

    Win32API gives you DialogProc, which only allows you to return TRUE or FALSE, I cannot call a default dialogproc, then do something, then return.

    overriding WM_ERASEBKGND to perform a ExcludeClipRect on a control does not work for me...
    but it did in MFC.

    any ideas anyone?

    solved, use "Clip children" in dialog resource to prevent flickering, not erasebkg processing override needed anymore ;-)

    Just curious. Do you think that has to be different in MFC?
