Preventing insert of new page

Tech-Archive recommends: Fix windows errors by optimizing your registry

Anyone know of a way to prevent the insert of a new page as I only want
my user to create new pages via my application (from vba) to control
the page naming and create various user properties etc. I only seem to
be able to get an event after a page has been inserted and the new page
dialog has appeared. I could delete the page after its been added if
this has not been created by my application, but not a very nice
solution.

It would be nice if visio had before events for lots of these types of
commands.

Thanks
