      Well done on creating your c# application.......so why post your question in the vb forum? You will need to have a mechanism that records when the application was first used and then check the time stamp on each successive startup or at a random time during running the application in a background worker thread. Obviously you would have to have the saved date/time obscured in some way so the user can't edit it to circumvent the mechanism. Applications such has winzip (i think it was this app) used to use a strange named registry key, buried deep in the registry, but using tools such as regmon, you could monitor the application startup, discover the key location and change the value.
