Called by the framework to retrieve the size, in HIMETRIC units, of the OLE item.
Specifies the aspect of the OLE item whose bounds are to be retrieved. This parameter can have any of the following values:
DVASPECT_CONTENT Item is represented in such a way that it can be displayed as an embedded object inside its container.
DVASPECT_THUMBNAIL Item is rendered in a "thumbnail" representation so that it can be displayed in a browsing tool.
DVASPECT_ICON Item is represented by an icon.
DVASPECT_DOCPRINT Item is represented as if it were printed using the Print command from the File menu.
Reference to a CSize object that will receive the size of the OLE item.
If the container application was written with the Microsoft Foundation Class Library, this function is called when the GetExtent member function of the corresponding COleClientItem object is called. The default implementation does nothing. You must implement it yourself. Override this function if you want to perform special processing when handling a request for the size of the OLE item.
