Hi;


I would require a assistance for the following questions :

I must implement a soft which lock an application : the use of the application is subjected to a licence. This licence is to activate by one encrypted key (its possible to use the application for one given length of time).
Authorization = Authorizes the use for a number access users limited + creation of a number limited of folder into the database.

How to solve the following problem:

- How to build the code of activation (I thought of a doublet:
hardware hash + a ID) ?
- To control the authorizations into the database ?
- How to block the software properly?

Regards;
