There are different ways to achieve this

1) encrypted license files that contains the expiry dates etc.
2) encrypted license keys held in the registry
3) challenge/response mechanism which require an internet connection
4) probably others.......

Try: License Key Generation[^] or: How can I create a Product Key for my C# App[^] or: c# Licensing[^]
Couple of them are in C# which can be seen to start on Vb.NET
Also,
Cryptography 101 for the .NET Framework[^]

Hope this helps.
