Hello

Take a look at the free and open source tool

www.activelock.com

That is a control you can add to your form to achieve the time limitation. Users can also enter a "unique" key (Different for every PC) to unlock the application.

Hi
 
       u can use SaveSettings Function to store some data (eg. a count) in registry.
using GetSettings Function u can retrieve it back. for each time u open the application make updation to this count and can block running application after a specified count is reached.

I'd definitely go with software passport from silicon realms.  Most protection schemes are easily crackable and for the price of this software and considering the ease of use, it's the best software most developers could ever buy.

Most of the shareware developers from the association of shareware professionals use it.
