There are many different ways to do this.......

You can hard code a date in your startup code. If run after that simply have program quit.

You can put a table with a date in it that gets checked on startup.

No matter which way you employ you'll have to plan how to "disable" the feature if the program is to continue after the trial period. By the way the above examples generally make for mad users......
