    Resolved [RESOLVED] [2003] Getting the right Date

    In the program im working on, it has a time trial version. Right now I have the program pulling the system date into a variable and checking it with a date file it creates when it is first used.

    The only problem with this is all the user would have to do when the time trial ran out is set the date on the computer back. Is there a way to pull a date into a variable that can not be changed by the user?

    Code:
    Public Class MyCar
    Public Sub Camaro()
        Dim Camaro As Car
        Camaro = SS.Fast("Sexy")
    End Sub

    Public Function Fast(ByVal sexy As String ) As String
        Return "SUPER" & sexy
    End Function
End Class

    Re: [2003] Getting the right Date

    You could get the date from a time server on the Web, as long as you don't mind enforcing an Internet connection every time your app is run.

    The only other way to cope with this is to record the time each time the app exits, then compare the current time to that when it starts up. It doesn't guarantee that the user won't turn their clock back but it does guarantee that it always goes forward for each run so the time will eventually run out. The user could always just increment the time by a few seconds each time they run the app but doing that would be a real pain so someone would have to be very determined to bother.

    The other issue is where you store this information so the user can't edit or delete it.

    Never done it myself. I think it's a specific protocol but I'm not really sure.

    I'm not sure but the Network Time Protocol, NTP, could be whats needed here.
