L_UINT32 dwFlags;	/* flag that indicates which object(s) to use */

Gets the physical bounding rectangle for the specified object(s).

Parameter	Description
pRect	Pointer to a RECT structure to be updated with the bounding rectangle of the specified object(s).
dwFlags	Flag that indicates which rectangle to use when updating the pRect parameter. Possible values are:
	Value	Meaning
	0	pRect will be updated with the rectangle containing all objects within the vector handle.
	VECTOR_FLAGS_SELECTED_ONLY	pRect will be updated with the rectangle containing all selected objects within the vector handle.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.
