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 section called “Working with User Objects” in Users Guide.

For more information about using the OLEStorage object in an
application, see the section called “Using OLE in an Application” in Application Techniques.
