);

Pointer to a VIDEOINFOHEADER structure to be filled in.
- pBufferSize
Size of the video buffer.
- pSourceRect
Rectangle dimensions of the source video.
Return Value
Returns an HRESULT value.
Remarks
This member function is a helper function used for creating memory image renderings of DIB images.
It is called from the base class implementation of CBaseControlVideo::GetCurrentImage when a null pVideoImage parameter is passed to that member function.
As a result, this member function constructs and returns a VIDEOINFOHEADER structure, using the information in pBufferSize and pSourceRect.
