how can i get ppt file infomation(such as slider count,slider time) without
MS Office support? thanks!
That is, without having PowerPoint installed?
There's at least one commercially available tool that would probably allow
this (can't remember the name at the moment, drat it).
Or you can learn how to parse the two extant file formats (the older binary
format and the new XML/ZIP-based one). Big job.
