How looping an effect "until end of slide" through code !!

[mauro fiore]

Hello all,
I know that PowerPoint 2003 cannot combine/group a sequence of
animation effects and have that sequence loop continuously;
but then how is it possible obtain, through a language (C# or VB),
a text loop continuously until end of slide with a animation effect?

I created a presentation with 1 slide and 2 textFrame
The first have an effect msoAnimEffectCrawl with right direction and
set the Repeat combo to until end of slide while the 2nd hadn't any
interval option setting.

Then I wrote a program in C# to view the objects of my presentation.
With debug I stopped the program to check the objEffect and
I saw that the only values of properties changed are:

shape: 1st 2nd

Timing.Exit msoTrue msoFalse
Timing.RepeatCount 0 1

I tried to set this properties, through the program, to the 2nd shape
but I didn't receive the value of Repeat combo changed.
How can I, through the code, to obtain an effect animation "until the
end of slide" ?

Thanks all,

Mauro
