RTFM на предмет OLEObject object и далее
PowerBuilder HelpThe OLEObject object acts as a proxy for a remote OLE object.
You can customize your own version of the OLEObject object by defining a standard class user object inherited from the built-in OLEObject. You can then access the OLEObject events by writing scripts that contain code for the events.
OLEObject objects are displayed in the OLE tab of the Browser as Programmable Objects.
Platform note OLE Objects are only supported on Windows.
For more information about creating a custom OLEObject object, see the chapter on user objects in the PowerBuilder User's Guide.

For more information about using the OLEObject object in an application, see Application Techniques .
OLEObject is a dynamic object In order to support OLE, OLEObject is a dynamic object. The PowerBuilder compiler will accept property names and function names and parameter lists that are not already defined for the object. If the properties or functions do not exist during execution, you will get an execution-time error.
