A trial program?

Dear all,

I would like to offer a 30 day trial period for my program I am developing.

To end the 30 days trial, either the program does not operate or the user has to enter a Serial number to end the 30 day trial.

Can this be done in VB?

Thanks

Take a look at this chapter in a book by Dan Appleman (http://www.itknowledge.com/reference/archive/1562765108/ch26.htm)

I think many time limited approaches can be got round by re-setting the computers date and time.

Search the net for a thing called "ActiveLock". It's cool!
Active Lock lets you make Trials, Demos, CrippelWare, enable/disable features based on serial number, and is protected against changing system date.
