I am using PB7.3 OLEObjects to access Panagon(a software)
objects.In some cases, when i request a reference to
an object, we recieve a NULL pointer stored in the
OLEObject. This typically happens when the object
we request(for what ever reason) doesn't exist,but i
i thought it did. The program tries to then call
methods of the returened object and PB generates
a NULL object reference error, and it goes directly
to the SystemError script. Result: The program crashes
I came to know that we can trap errors while
accessing external objects by creating
a new Standard class user object which is
inherited from oleobject. Using ExternalExceptionEvents
we can trap the errors.
I dont know how to use this techinique in my case.
I'd sure like to know if you can shed any light
on this topic.
Any help you could provide would be greatly
