The OLEStream object acts as a proxy for an OLE stream.
You can customize your own version of the OLEStream object by defining a class user object inherited from the built-in OLEStream object.
For more information about creating a custom OLEStream object, see Working with User Objects in Users Guide.
For more information about using the OLEStream object in an application, see Using OLE in an Application in Application Techniques.
