You can store the encrypted expiry date in the registry at the time of setup. And at the runtime you can check the expiration period.

Or you can have a encrypted licence file along with your dll at the root directory. If somebody using the trial version you can use the 15 days trial licence file which contains the expiration date in the encrypted format.
