Depends on what you want to do. I assume the trial version is a limited version of your real product.
Some people use a registration code mechanism. Without the registration code, the program has some locked-out functionality, and there is often some time limit before the program cannot be used (or gets even more limited functionality). Others build separate trial-versus-full versions, with or without time limits. A third way is to do some kind of "nag-ware" scheme. I don't recommend having the application uninstall once it's expired, but doing a lock-out is easy enough. Just check to see if the lock-out conditions have been satisfied (say, you keep a timestamp in the app's preferences and check it on start-up). You can also keep the registration code in there as well. The usual trick is to have a reg code based on the Hotsync ID, but there are other schemes available.
