But problem is that when I modified it pattern like <^^%#^ - ^^^^^ - ^%%%^ - ^%^%% - ^%^^^> then it comes in different textboxes, how i can impliment trial and serial number?
Can anybody show me the way ?

What you are talking of is a Licensing option in your software.
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
