Determines if a target rectangle is valid.
virtual HRESULT CheckTargetRect( RECT * pTargetRect );
Parameters
- pTargetRect
- Target rectangle to check.
Return Values
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.
