I have such a system in place. I coded it from scratch. It works really well. Not only does it manage whether or not the license is valid, and refuses to run the application in that case, but it also lets us centrally control access to application features. Hint: Allow the computer to be offline by only requiring a check of the license every 20 days or so. Usually, people will be connected and the license status can be checked immediately. But sometimes the connection will time out (problem on your end, their end, or somewhere in between) and sometimes they are just on the commuter train with no Internet. Don't make them want to throw their computer at you. :) Paul _______________________________________________ Post Messages to: ProFox@leafe.com Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/4f26eeb7.1090...@ulmcnett.com ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
