Hi,
I know it is pointless saying thanks to everyone who has responded to the odd !! questions I ask from time to time but I have finally produced an app, basic one but selling OK, so thanks to all forum members. Could not have done it without the man from Ulaan Baatar and many others.

Q.
Is it possible to build in an "expiry date" into an app.
I will be issuing annual updates to the app and want to make sure purchasers have to accept the update [all clearly and legally detailed in the purchase docs]
or have their current app expire...meaning become inoperable?

So, I think what I want is to code in the purchase date and then add 365 days to it after which time the .exe will not be usable.
Nasty but necessary.

thanks in anticipation and thanks to the forum managers for the happy birthday wish recently, very impressed!!
