Hi, You can save the last date the program has run and the amount of day left. Then user cannot activate by setting the clock back.
If you decrement the remaining days every time the program is started or run on a day other than the last day of run then you can decrement the amount of days left counter. Advantage is that your user can really run the program for 30 day's even if he don't use it for a week or so. -- mvg, Wilfried http://www.mestdagh.biz http://www.comfortsoftware.be http://www.expertsoftware.be > -----Oorspronkelijk bericht----- > Van: Delphi [mailto:[email protected]] Namens Rich Cooper > Verzonden: woensdag 4 juni 2014 17:41 > Aan: 'Moderated List for the Discussion of Delphi Programming excluding > Database-related topics' > Onderwerp: RE: Question about using the Delphi Deployment tool > > I'm about to release a new program.
