Chart Control, Unbound Object Frame Control.
You can use the OLEClass property to obtain a description of the kind of OLE object contained in a chart or an unbound object frame.
This property is set automatically in the property sheet to a string expression when you click Object on the Insert menu to add an OLE object to a form. The OLEClass property setting is read-only in all views.
The OLEClass property and the Class property are similar but not identical. The OLEClass property setting is a general description of the OLE object while the Class property setting is the name used to refer to the OLE object in Visual Basic. Examples of OLEClass property settings are Microsoft Excel Chart, Microsoft Word Document, and Paintbrush Picture.
