OnError Event (Err)

OnError

The OnError event is called if an error has occurred.

In order to receive the event, some preparatory actions must be taken:

1. In an object that is available at run time, provide a class variable from the Type COM pointer, and then set the class to TCEServer.ErrorObject. Initialize the class variable with Err.

2. Now set the DisplayLevel of the Err object to use the OnError event to handle errors.

Err.DisplayLevel := TCEServer.ErrorDisplay.ErrorRaiseOnErrorEvent

As a result, all unhandled bugs are forwarded to the OnError event. You can use this event to log the errors that have occurred in a log file or database.
