COleClientItem::SetDrawAspect
Visual Studio 2012
Call the SetDrawAspect member function to set the "aspect," or view, of the item.
virtual void SetDrawAspect( DVASPECT nDrawAspect );
The aspect specifies how the item is to be rendered by Draw when the default value for that function's nDrawAspect argument is used.
This function is called automatically by the Change Icon (and other dialogs that call the Change Icon dialog directly) to enable the iconic display aspect when requested by the user.
