    File Expiration

    My company is thinking about putting our catalog on CD for our Road Reps and maybe even our customers. We'll probably use Acrobat.

    We publish a catalog twice a year, January and July. Along with the usual copyright information, we would include an expiration date on the index page. We'd also print this expiration date on the CD itself.

    Our concern is the customer who may be looking at our January 2003 catalog in October of 2005. By that time, many items will have been added, numerous items will have been deleted, and several prices will have changed.

    We use Quick Disc (Rimage) to create CD's. We can set a "Volume Expiration Date" on the CD, but we expect users to copy the catalog to a hard drive for faster access.

    We need a method of letting the customer know his CD is out-of-date, whether that be a pop-up window or maybe the catalog file won't open.

    Any experiences or suggestions?

    Create an installation program for the CD.
    As each CD is installed, the installation program can replace out of date files.

    If you allow users to directly read the files from the CD-ROM, then there's not much you can do, unless reading the CD-ROM is under the control of an installed program that can keep track of different CDs.

    I have heard that Acrobat supports JavaScript or something like it. This might enable you to pop up a message after the expiration date alerting the user to get an updated copy.

    Acrobat 5 does have a Javascript item in the Tools menu.
    Until Monsieur Scher mentioned the critter, I did not even notice it was there.

    Someone even managed to send out an Acrobat virus last year, but it only infected people who had the full version of Acrobat, not the Reader.

    Is there a way to disable Javascript in Acrobat 5?

    I can't help on this one, I only have Acrobat 4.

    In Acrobat 5.

    There is an option to disable running Javascript in the Preferences | JavaScript menu.

    I think you're on to something, Monsieur Scher.
    I found this in one of the Adobe Forums (yeah, I know, I've been unfaithful):

    "A cheap work-around I use is to create a field that covers the entire page and set it to 'hidden.'
    Then have some doc-level JS that changes it to 'visible' if it's after a certain date.
    It's not fool-proof and it's not too difficult to get around, but it's better than nothing."

    This sounds like it will work for us. We're not really worried about customers "getting around" it;
    we just want to make sure they know their eCatalog is out-of-date.

    Thanks for the input.
