CBaseControlVideo::SetDefaultDestinationPosition

The SetDefaultDestinationPosition method sets the renderer back to using the default destination position (typically the entire window client area).

Syntax

  HRESULT SetDefaultDestinationPosition(void);

Return Value

Returns an HRESULT value that depends on the implementation; can be one of the following values, or other values not listed.

Value Description
E_FAIL Failure.
NOERROR Success.
VFW_E_NOT_CONNECTED The operation cannot be performed because the pins are not connected.

Remarks

An application can change the source and destination rectangles for the video through the IBasicVideo interface. The source rectangle affects which section of the native video source will appear on the display; the destination rectangle affects where the video will appear when played. The destination rectangle is relative to the client area of the window in which it is playing. The upper-left corner of the window is coordinate (0,0).

Requirements

**  Header:** Declared in Ctlutil.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
