Status: Verified
SYMPTOM(s):
ActiveX Automation Object does not send events back to Progress
ActiveX Automation Object built in Visual Basic does not send events back to Progress
ActiveX Automation Object does not use the IDispatch event interface to handle events
FACT(s) (Environment):
Progress 9.1D
Progress 9.1E
OpenEdge 10.0A
OpenEdge 10.0B
Windows
CAUSE:
Bug# OE00086341
CAUSE:
When an ActiveX Automation Object tried to enable event-handling with Progress, if the event-handling interface being used was not the IDispatch event interface then an error would be returned indicating that Progress did not know how to handle events from whatever type of object the ActiveX was using (all Progress supported was the IDispatch event interface for event-handling).
FIX:
Upgrade to 9.1E01 or later.
Upgrade to 10.0B02 or later.
Progress 4GL now looks at the type (class) of the object that is trying to enable events with Progress. If it is derived from the IDispatch event interface, then Progress goes ahead and allows the event-handling to proceed.
