CBaseControlVideo::CheckTargetRect

The CheckTargetRect method determines if a target rectangle is valid.

Syntax

  virtual HRESULT CheckTargetRect(
    RECT *pTargetRect
);

Parameters

pTargetRect

Pointer to the target rectangle to check.

Return Value

Returns E_INVALIDARG if not valid; otherwise, returns NOERROR (S_OK).

Remarks

This member function determines if the target rectangle requested is valid. Because the destination rectangle specifies a position in the logical client of the window, the coordinates can be negative, although the overall width and height cannot be zero or a negative value.

Requirements

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

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