Handling a datebook press

[Robert Moynihan]

Hi folks,  what I want to do is to intercept a datebook hardbutton key 
press, and handle it manually.  If conditions are not met I want to 
ignore the button press completely, and I'm not sure how to avoid the 
launch of Datebook, or kill it if it is underway.  I've tried using the 
sysNotifyVirtualCharHandlingEvent and sysNotifyAppLaunchingEvent 
notifications to detect the press, but both seem to be too late, after 
the launch of Datebook is already in the queue.  So, a couple of 
questions/comments:

Is using a notification the right way to go?
If so, have I chosen the wrong notifications to try?
I thought that changing the priority of the notification might help, but 
I couldn't detect any improvement.
If I've used the right notifications, what method must I use to kill the 
app launch event already queued up?  Surely it must be possible, but I 
just can't find a way (I've tried emptyin queues, flushing queuse, 
enqueuing other events, etc.,  with no success).

Thanks for any assistance.  Bob.
