Filtering Asynchronous COM Events (-filterocxevents)
The
–filterocxevents
startup parameter, lets you control the conditions under which you want asynchronous COM events handled. An asynchronous COM event is one that is sent by an ActiveX control or Automation object because of an external event, rather than in response to user input. One example of this is the Tick event from the PSTimer. Another is an event signalling the receipt of a message from an external source, such as a control that implements a mail notification system.By default, asynchronous COM events are handled when any of the following conditions occur:
Handling COM events during the second and third conditions might cause random problems in your application, depending on what 4GL code is executed in the event trigger. You use the
–filterocxevents
startup parameter to prevent asynchronous COM events from being handled during the second and third conditions.
