Possible Usage Scenarios
Aspose.Cells provides the OleObject.ClassIdentifier property which you can use to get or set the class identifier of an embedded OLE object. OLE object class identifiers are actually GUIDs, i.e., globally unique identifiers. A GUID is always 16 bytes long; therefore, class identifiers are also 16 bytes long. They are often found inside the Windows Registry and provide information to the host application about how to open an embedded OLE object containing various embedded resources inside the client application.
