Powerpoint slides

I have trawled through the posts on Powerpoint and can't find any info on.......

Identifying text frames on a slide - is there any way to identify a text frame in Powerpoint slide? I am trying to add text to various (existing) text frames in code but can't easily identify the frames without recording quick macros to select a frame and looking at the code to see which frame I have just selected...

Also has anyone seen any code to display a single slide within a VB form?

I am trying to write a program that will show a thumbnail list of Powerpoint slides and am getting nowhere fast as I can't even display a single slide!

The other way around it would be to generate jpg images and show these but I don't want to if possible.

Any help appreciated
Thanks
