How can I load a powerpoint presentation and run it with AS 3.0. Which is the best way? What should I do? Please help 
That really depends on how much you know about AS3. If youâre not too experienced, you probably mean âhow do I show a powerpoint presentation with Flashâ. Thatâs simple enough, but dynamically loading a powerpoint with AS3 would be quite a project. If you want the second one, Iâd suggest searching âAS3 powerpoint loader classâ or something similar to see if somebodyâs already made a class for loading powerpoints. If they havenât, itâs probably not possible.
If you just want to play a powerpoint in flash, just ask and Iâll tell you how.
You can insert Flash movies inside PowerPoint, but actually inserting PowerPoint within / converting PowerPoint to a Flash file is not possible.
If youâre a Windows programmer, you could write an external interface to control a PowerPoint presentation running inside PowerPoint from a separate Flash app.
If all you want to do is launch a PowerPoint presentation file from within Flash, you could load it as a URL as you would for a web page.
There are programs out there which will convert a Powerpoint presentation into a Flash movie. Google âpowerpoint to flashâ or something similar.
Conversion, yes, but direct insertion, no.
You canât convert to .swf and then load that .swf into your main movie?
Not something Iâve ever needed to do. Just wondering if itâs possible.
