Path ==== Source: DXSDK\Samples\Multimedia\DDraw\FullScreenDialog Executable: DXSDK\Samples\Multimedia\DDraw\Bin User's Guide ============ FullScreenDialog requires no user input. Press the ESC key to quit the program. Programming Notes ================= For details on how to setup a full-screen DirectDraw app, see the FullScreenMode sample. If the display device supports DDCAPS2_CANRENDERWINDOWED then to make GDI write to a DirectDraw surface, call IDirectDraw::FlipToGDISurface, then create a clipper object which GDI uses when drawing. To display a dialog, then simply create and show it as normal. If the display device does not support DDCAPS2_CANRENDERWINDOWED (some secondary graphics cards are like this) then the card does not support FlipToGDISurface. So it is necessary instead to have GDI make a bitmap of the dialog to be drawn, then blt this bitmap to the back buffer. However, this sample does not show how to do this technique,
