Is there a means in PowerPoint VBA to determine the default file save
location?
Better yet, is there a means to change that default location?
Hmm. Y'know I don't think I've ever messed with this.
You set it manually using Tools, Options, Save tab.
Most of the settings you make there get saved to the registry, down in HKCU
Software/Microsoft/Officexx/Powerpoint/Options or words to that effect.
Try setting the default save manually to some oddly named directory then have a
look in that section of the reg for the same directory name.
Setting it via VBA is another matter. PPT reads this section of the reg at
startup, writes back to it as you change things manually but never re-reads it
until the next session, meaning that you can't write to it while PPT's open and
affect anything.
If you're automating PPT from another app, you can write to the registry then
fire off PPT, no worries.
From w/in PPT, you'd need to use SendKeys to change the settings. Ugh.
