Well, you can't actually prevent it.  Depending on the OS version, windows automatically synchronizes the time with timeservers.  It allows this since a computer's time does fluctuate (it's not 100% accurate on all pcs, close, but it does get off).  Not to mention when you have to deal with daylight savings times.

And if you think about it: how do you know what time it really is?
Unless you have a program run 100% of the time, keep track of time itself, comparing that time to the computers time, you wouldn't know if they changed it or not.  But if they did, there may of been a reason.

If the time is that important to you for the database, don't rely on the PC's time entirely - require an internet connection and query a timeserver for the time.  Then just use the timeserver's time for the database (well, with the time offset for the timezone).

well thank you very much to your very very nice suggestion to my problem..  I'm using a computer without internet connection, it is windows XP prof Platform.

If i make a program that monitor a time 100 percent time to time.. i need to run the program on startup but what if they accidentally close it.. so i need to create a program again to detect if that application is still running and reload it again if it was terminated ..

Other idea: since windows xp prevent changing the System date on Limited account it solves the system date changeable.

But the program i made in vb6 after installing and i run it in limited user account to prevent them changing system date time,  error display that seems the program won't run... i forgot the error msg it seems just {cls000000} .. but then i go to administrator account  and run it again nothings going wrong and it works..

I don't know if the problem is in application I'd made or might the program could run only in administrator account.. but some application like office run also in limited user account..right?

I don't know......!!!!!



very confusing                

I need help.. i will be looking forward to this thread...

thank you very much and thanks again in advance...
