vb.net Timebomb (trial timebomb with expiration)

[larry mckay]

Does anyone know how to develop or code a timebomb in vb.net that uses
either the registry or something else that would be take a fair amount
of time to hack.
I'm developing an application that I'm trying to prevent users from
distributing it after a particular time expires and I do not want for it
to be obvious for them to detect the timebomb or how to hack it.

Place it in the registry and encrypt it! Encryption will get most
"begginers" to stop hacking

In addition to Lars' reply, place it in a key with a name that won't make it
to easy to recognize, if a user uninstalls it and wants to re-install to
have another trial period (if that's what you want, that is...<g>)

I am not 100 % sure if it's possible with .NET's licensing mechanisms,
but have a look here:
