CLoadDirectDraw::LoadDirectDraw (Compact 2013)

  • Article

3/26/2014

Loads and initializes the DirectDraw library in the specified area.

Syntax

HRESULT LoadDirectDraw(
  LPSTR szDevice 
);

Parameters

  • szDevice
    This parameter is optional; if omitted, this method loads DirectDraw to the base drawing area.

Return Value

Returns S_OK if DirectDraw loaded correctly or E_NOINTERFACE otherwise.

Remarks

DirectDraw is not always available, so applications cannot statically link to the library. Therefore, this member function loads the library, gets the function entry point addresses, and calls them to create the driver objects.

Call this member function before calling CLoadDirectDraw::GetDirectDraw to retrieve the IDirectDraw interface.

Requirements

Header

dshow.h,
Streams.h

Library

ole32.lib,
Ole32auth.lib,
Strmbase.lib,
Strmiids.lib,
uuid.lib
