IDirectDraw4::FlipToGDISurface

The IDirectDraw4::FlipToGDISurface method makes the surface that GDI writes to the primary surface.

HRESULT FlipToGDISurface();

Parameters

None.

Return Values

If the method succeeds, the return value is DD_OK.

If the method fails, the return value may be one of the following error values:

DDERR_INVALIDOBJECT
DDERR_INVALIDPARAMS
DDERR_NOTFOUND

Remarks

This method can be called at the end of a page-flipping application to ensure that the display memory that GDI is writing to is visible to the user.

The method can also be used to make the GDI surface the primary surface, so that normal windows, such as dialog boxes, can be displayed in full-screen mode. The hardware must have the DDCAPS2_CANRENDERWINDOWED capability. For more information, see Displaying a Window in Full-Screen Mode.

This method should not be called once application creates a non-GDI primary surface as this leads to video memory leaks.
