Event Handlers
556
Moving over to the Event Handlers tab, we can see the many events that we can supply code for. Activate
the drop-down (as I have in Figure 18-17). While the default is OnError, we can deal with a very
wide range of scenarios. Let’s examine how a few of these might be used:
❑ OnError: Well, I would hope that this is the most obvious one. As you would expect, this event
is fired in the event an error is detected. It allows you to address the error in some fashion.
❑ OnWarning: Basically the same as OnError, but it allows you to examine and possibly address
warnings too.
❑ OnProgress: For long running processes, this can be handy for updating some form of progress
indicator (perhaps a status table somewhere).
❑ OnPreExecute: Allows for things like preparation code to run prior to starting the main part of
the task.
And this is, of course, just a taste. What events to use will vary by need.
