SUMMARY

When processing event notifications in an Microsoft Active Accessibility (MSAA) client, the client should not query the object properties during the EVENT_OBJECT_DESTROY event.

MORE INFORMATION

EVENT_OBJECT_DESTROY notifies an MSAA client that an object is being or was recently destroyed. Depending upon the type of object generating this event, querying the object for its MSAA properties may or may not produce valid results. Because of the uncertainty involved, it is recommended that a client not attempt to query objects being destroyed, or do so sparingly.

The information in this article applies specifically to Windows NT 4.0 Service Pack 3 and later versions as well as Windows 95.
