Hi Nick,
Thanks for the answers...
These are my futher findings:
- Slide ID is really in the Slide Persist Atom unless the slide is from the
Template
- The slide sequence is listed under the latest 1000 record under 4080 and
the sequence of 1011 shows the list slides ... There is no real Slide
number that I can find.
I am using Powerpoint 2002 SP3
Thanks

I've just taken a look at it, and the current slide ID stuff isn't ideal.
I'm going to have to sit down and do a proper review of it all, and make a
few changes, but that's not going to happen straight away.
For now, I've added a method to Slide to get the Slide's number (1, 2, 3
etc).

I'm not sure we always pass in the right SlideAtomSet, and we don't always
give a SlideAtomSet in all cases, so this isn't ideal. I'm going to need
to think about this a bit, and hopefully find a more ideal solution

Can you upload an example where this happens to bugzilla? That might help
me spot how it works/breaks, and can also make the basis of a new unit
test

As best I can tell, the slide atom doesn't actually have the slide number
(even though it would be an obvious place to put it). It does have the ID
of the associated notes field, which is also the Identifier in the
matching SlidePersistAtom, but if you don't have a notes field then
there's nothing to tie it up with :(
