Theoretically, yes.
For the user to delete a slide, they'd have to be in a view where they can
select slides (there may be an exception or two).
If they delete a slide in that view, the selection would change; you could
respond to the selection change event and at the very least compare a
previously stored count of the slides in the presentation against the current
count. If CurrentCount < PreviousCount Then (do your stuff).
I don't use VB.Net so can't offer any more specific help than that.
