Using NoBackPaint or BackPaint(EXCLUDEPAINT) seems to be ignored(on DHCtrl for sure,on Ctrl probably the same).
When main window is resized, flickering is seen.
This could be probably solved on wPlatform with overriding WM_ERASEBKGND(just ret TRUE) if main Registered hBrushBack!=NULL.

Well, if you are using DHCtrl, you are sort of supposed to override

virtual LRESULT WindowProc(UINT message, WPARAM wParam, LPARAM lParam);

BTW, what is your reason to use DHCtrl?
