I was wondering if there was a way to set a time limit on a pdf file where maybe it would stop opening after the set time? I know this software claims it can: http://www.armjisoft.com/?page=pdfownerguard But it costs like $1000. So is there another way to make the PDF stop working(or just not open) after the amount of time you set it? Thanks to those who help!
Like if there was a way to set the AMOUNT of days it's allowed to be open instead of setting what date it closes.
This is what I would do: Using InDesign CS5 add an SWF into the page with the content. Have the SWF check the time.
