Return value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero.

Remarks

If uType is either DFC_MENU or DFC_BUTTON and uState is not DFCS_BUTTONPUSH, the frame control is a black-on-white mask (that is, a black frame control on a white background). In such cases, the application must pass a handle to a bitmap memory device control. The application can then use the associated bitmap as the hbmMask parameter to the MaskBlt function, or it can use the device context as a parameter to the BitBlt function using ROPs such as SRCAND and SRCINVERT.
