Well, I guess I can't help you there, Satya. I've not used the Registry, or ASP or IIS. My method is a holdover from the old FPW 2.6 days and I'm simply using .MEM files on the local workstation.

>This sounds very good. I stored the Demo Installation date in 2 places in Registry in encoded form. What I am facing problem is with the internationalization. Say if I install the Package on Norway machine then I am facing the problem in retrieving the Date. Also I do not have permission on Registry as my demo uses ASP over IIS, if I install the demo on IIS Server. Is there any way other than this method that can be used for trial checking.

>>Hi Craig,

>>I checked out your KB article because I was curious as to how other people implement this. I generally use the date scheme myself (give them 30 days, and also give them a way to extend it if they call me --- I give them a 15-digit code over the phone to enter to either extend the demo period or remove it once they've paid me). The only objection you seemed to have was that there was no way to prevent them from changing the system date. You're right about that, but what I do is save the current date each time the program is run. When you do your security checks when the program first starts, you can check if the system date is less than this saved date. If so, you know someone screwed around with the system date and then I immediately expire their demo. Once it's expired, they have to call me to get it back.
