I'd like to write a application that opens a PowerPoint presentation and
plays it to the end, all without user intervention. I've written a Java
program (based on the PresentationDemo sample - see below) that:
Opens the presentation
For each page, sets the Change = 1 and Duration = 5
Sets IsAutomatic = False in the Presentation property set. Together
with above displays each page for 5 seconds then moves on.
Starts the presentation.
However, this will stop as soon as the first animated shape is encounter
and waits for user input before animating and proceeding (which is
unacceptable for my application since there will be no user input).
Explicitly disabling the Animations Allowed property (both in the UI and
from code) doesn't appear to do anything - the presentation still waits
for user click before proceeding. Have I misunderstood what this
feature will do?
One possible solution is to set Custom Animation ~ Effect ~ Start =
"After Previous" and set the Effect Options ~ Timing ~ Delay = "a few
seconds", applying these settings to each relevant animated shape.
Unfortunately, I can't find a way of doing this through the API. Is
this method supported through the Java / C++ API?
Are there any other suggestions to accomplish hands off playing?
I'm currently using Java for prototyping, and will rewrite in C++ once
complete. Running version 2.0.2 under FedoraCore4.
Thanks,
Andy
