Hi,
Any how you cant stops user to install application once u
issue a disk to a user, (as you can�t write on disk. But you can prevent the
execution of application by using software lock. In future in same software
lock you can implement hardware lock.
<o:p></o:p>
To do this write a component in which will maintain
encrypted license information like number of user� date of installation name
of server and expiry date if any and so on. This information you can store
inside database/ registry or in any file.
<o:p></o:p>
Install this component on the server along with your
server application. You can also use DCOM to refer this component in your
application. Every client before start will check first this component and
then proceed further or while execution client can check for license
frequently. Because license information is stored centrally we (as a developer
company) can modify this information whenever we want. There is no overhead on
us when user makes any changes to his system.
<o:p></o:p>
Using this lock
<o:p></o:p>
1 User can install n number of application in the
network.
2 User cannot execute applications more than the number
of lic. he obtained.
3. User can play with his machine uninstall application,
reinstall on same machine or on different machine.
4. All
information lic. is centrally available.
5. Encrypted
file can be included in installation.
Regards
Kishor
