However, I seem to remember (and it's been awhile) that with certain commands, once
the command is generated, it is still too late
to stop it from occurring because you are simply being notified, as opposed to
triggering the event.
In that case, just get the location of the silk button arrays from the
EvtEnumSilkSomething command (sorry can't remember off hand),
compare the region with vhrFind, or whichever you want to intercept, and then check on
a penDown event for it being in that
rectange. If it is, instead of passing that penDown to the system, call your special
function.
