OLEStorage object

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.
