Class Property

See Also         Example         Applies To

You can use the Class property to specify or determine the class name of an embedded OLE object.

Setting

The Class property setting is a string expression supplied by you or Microsoft Access when you create or paste an OLE object.

You can set the Class property by using the control's property sheet, a macro, or Visual Basic.

Remarks

A class name defines the type of OLE object. For example, Microsoft Excel supports several types of OLE objects, including worksheets and charts. Their class names are "Excel.Sheet" and "Excel.Chart" respectively. When you create an OLE object in Design view by clicking Paste Special on the Edit menu or Object on the Insert menu, Microsoft Access enters the class name of the new object in the property sheet.

Note   To determine the class name of an OLE object, see the documentation for the application supplying the object.

The Class property setting is updated when you copy an object from the Clipboard. For example, if you paste a Microsoft Excel chart from the Clipboard into an OLE object that previously contained a Microsoft Excel worksheet, the Class property setting changes from "Excel.Sheet" to "Excel.Chart". You can paste an object from the Clipboard by using Visual Basic to set the control's Action property to acOLEPaste or acOLEPasteSpecialDlg.

Note   The OLEClass property and the Class property are similar but not identical. The OLEClass property setting is a general description of the OLE object whereas 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.
