Does PowerPoint have a document variables equivalent?

[Guest]

Word has document variables, so you can store data within the document, does
PowerPoint have any sort of equivalent? I've been looking around and haven't
found anything. Of course, there are other methods of storing data, but I'm
curious if PowerPoint has an internal way.

Thanks

Two common methods are :
- Storing values in custom document properties. This is only available at a
presentation level. Also, it is accessible in the UI via File | Properties |
Custom tab.
- Storing values in tags. This is available in presentation, slide and shape
levels. There is not UI to access tags, it can only be done programatically.

Looks like the tags are exactly what I was looking for.

Thanks for the help

Shyam, do I recall correctly that there's a limit to the amount of data you can
store in custom properties -- that it's part of that 32 or 64k chunk that PPT
allocates to that and to link storage?

I did some testing with tags a long time back, PPT97 I think it was, and found
that you could store literally megabytes of info w/o running into trouble.

One interesting bit was that there's a definite advantage to storing fewer tags
with larger chunks of data rather than lots of tags, each with a small bit of
data. Given the same amount of data stored, the file with fewer tags will open
noticeably faster, apparently due to the overhead of setting up each tag as the
presentation opens.

Your mileage may have varied since then. <g>
