I have a self-running presentation. Some of the slides depend on the time. I have created an Excel file with the time table. The presentation initially reads the valid times for each slide. A slide can be valid till "09.09.2013 17:00". Thereafter it should be hidden. I have done it with VBA function "OnSlideShowPageChange": If the time-table-time is less than now() then move to slide + 1. (.GotoSlide i + 1).
There is however a problem: When the slide should be skipped, it actually shows up, but immediately changes to next slide. Is there a function or property acting in advance - not when the event already has been triggered?
