Do you have any ideas on how to make a yearly expiration/subscription in your VB.NET application?

Recommended Answers

Save the date and time when the app was first run, then just pop up a nag and exit if it is mote than one year old. The first-run date could be saved in a Settings variable or the registry (possibly encrypted to prevent abuse).

Store your date data in an encrypted file. At the time when application starts decrypt the file and pick up the date value and check it.
