Call this function to retrieve the OLE item's size.
Pointer to a SIZE structure or a CSize object that will receive the size information.
Specifies the aspect of the OLE item whose bounds are to be retrieved. For possible values, see SetDrawAspect.
Nonzero if successful; 0 if the OLE item is blank.
If the server application was written using the Microsoft Foundation Class Library, this function causes the OnGetExtent member function of the corresponding COleServerItem object to be called. Note that the retrieved size may differ from the size last set by the SetExtent member function; the size specified by SetExtent is treated as a suggestion. The dimensions are in MM_HIMETRIC units.
For more information, see IOleObject::GetExtent in the Windows SDK.
