I have the ppt and i want it to use the cfpresentation but dont know how to do it. i've been looking some example from web and don't understand about it because some used .flv, some used swf, jpg, ect. i have no idea what those for. I found this example to converts a PowerPoint presentation to an Adobe Connect presentation but don't really understand the code where there have the video1.flv? why it needs .flv or swf or jpg for?
It's not clear to me what you're trying to do. Are you trying to use <cfpresentation> to create a ppt file? Or are you trying to use <cfpresentation> to convert a ppt file to something you can put online (either HTML or Flash)?
Have you checked out these documentation links?
