(would need some advanced cryptography to be secure too)<br /> No such system exists today though.</p> <p>What you can do is to make it slightly harder to install, by leaving some marker information behind in the phone, for example a file or another kind of "setting", that you check the next time it is installed.<br /> But only "slightly harder", and will only stop the naive (and the honest) user.<br /> </p> Wed, 19 Dec 2007 11:55:55 +0100 alh comment 43596 at http://www.newlc.com http://www.newlc.com/forum/how-set-expiry-date-application <p>I want to build a application for ex: any(Hello World) application and I need to set the expiry time or date for that application.</p> <p>So that after the fixed time(epiry time) no body can install or run that application.</p> <p>Please give me proper idea about constructing this code as Iam a beginner in symbian developing.</p><p><a href="http://www.newlc.com/forum/how-set-expiry-date-application">read more</a></p> http://www.newlc.com/forum/how-set-expiry-date-application#comments Symbian Signed Fri, 14 Dec 2007 14:06:05 +0100 shravan_vip 19812 at http://www.newlc.com
