The OLEStorage object acts as a proxy for an open OLE storage.
You can customize your own version of the OLEStorage object by defining a class user object inherited from the built-in OLEStorage object.
For more information about creating a custom OLEStorage object, see the chapter on user objects in the PowerBuilder Users Guide.
For more information about using the OLEStorage object in an application, see Application Techniques.
