yaa... I think you are right. Let me think over hoe to accomplish it. Thank you very much for your replies. Thanks
I think you should be asking why do I need to do that? What actually am I trying to accomplish? -Saurabh

I didn't get you in your previous reply. If you are asking what i am trying to accomplish is clear. I want to expire my application on particular date. but i can't use local time/date to check it as user may change its local time/date. That's why i am thinking of some other way. Please help me if u have some suggestions for me. Thanks

Hello all, I am building Win32 application. My requirement is to expire this application on a particular date let say for e.g. on 31 december, 2008. If i use system's local time then user will be able to run it by changing its date/time. So is there any way to get global time in my VC application. Please help me out in this situation. Any help would be greatly appreciated. Thanks

I don't think that is the goal. If that is the goal then may I ask why do you want you application to suddenly stop working for every user. What purpose the purpose of this? There is no suggestion I can give you for finding time, even if you assume that you want time in a particular time zone. As far as I know there is no way for a standalone computer to determine current time. In fact no device can have such capability because time is not absolute. -Saurabh

Hello, you can save the current date every time the program runs, so you can check against the date for alterations. Hope this helps Bekir.
What if date has been altered before program was installed? Saurabh

My suggestion is to follow what beko said. In addition to that you can mark it as expired once the expiry date reached. After that you should not allow the application to continue working even if the date is changed back.

Hello, Either limit the number of days also or if you are providing a license, do not proceed if the supplied date is earlier than the start date of the license. You could also use both, if you want it. The only drawback of this approach is that, if the user changes the date to an earlier date for any purpose (reports :)), and mistakenly opened your program also, he/she would be pissed off ;P .

Thanks for your reply. I also thought about the suggestion for getting global time from server till PC is connected to Internet that you have mentioned. But that's not my requirement. what could be the other way to do so?? As I told you that i need to expire it on particular date. Your suggestion would work if i need to expire it after number of days from its installation. Please help me out if you still have some suggestions. by the way thanks again for you reply. Thanks

If you already know that 31-Dec-2008 is the expiration date, and you installed the software today, then simply set the value to 53.

Actually that is the interesting thing. OP do not want to disable application after a given number of days, he wants to disable it on a particular date. -Saurabh
