I'll explain what we want to do and hope that somebody can give me tips on how we could do it.
We want Powerpoint presentation to start running automatically on a Windows XP PC, but it has to start according to a certain schedule. The schedule is in txt format, but this schedule changes continually (daily). Also, the schedule may say 8:00 but we need the presentation to always start 15 minutes earlier than the time displayed in the schedule.
Can somebody give me tips on how to achieve this?
