Is it possible to secure a pdf file in a projector?
I have created an interactive projector(4GB) so that students can perform lab experiments on the screen and would like to have the accompanying pdf textbook(50 MB) that I have made imbedded in the projector that can be accessed only from the projector. I see no mention of pdf in any of my 7.0 manuals. And, as I understand it, Play/Play Done would only work between movies.
Are these two media that don't meet?
