Creating a Demo Webpage using ASP.net
-
Hi, I am creating a demo ASP.net web page application which will be installed on client place for 30 days. I want my ASP.net application to stop working after 30 days. I don't want to reply on system date because user can always trick the application by changing the system date of Web server. I guess I will not have access to user system hard disk and registry because application will be running in IIS and it doesn't have access to them. Do you think if there is any other way I can manage trial version of my application. Thanks in Advance
If you have faith in the cause and the means and in God, the hot Sun will be cool for you.

You can store a timestamp each time the application is run. Then by comparing the previous date to the current date you will know if the clock has been turned back (You could then lock up the application). My 2 cents...
A dogged, arrogant belief in self and the childlike idealism that comes with not knowing my limits. This is my greatest blessing, my priceless attribute.

My suggestions for you Problem: 1. Create A webservice on your Server that should accept some arguments(IP) from client. It should check on what date the IP was registed. Difference between the Current and Date Registed. Should send TRUE/FALSE to client based on this. 2. Create a DLL for client. Before it serve any request to client, it must contact your Service, get the Status and proceed. 3. If expiry date is over, stop the DLL from execution.

I meant Application as in Web Application and not Page.Application You can always store them somewhere on the hard disk / registry... However setting up of read /write permissions might be tricky depending on how you wish to install the application.

You beat me to the punch. Good answer.
I didn't get any requirements for the signature
