You can work on serial nos. of Processor and motherboard of the system to generate your lock. Your can merge their IDs too for this purpose.

Thanks sk saini.I got serial of processor and motherboard for many computers.
I find out, some of computers have same processor id ,
also some of computers don't have motherboard's serial.

As you've found that some systems can have same processor id. So for a merged id (processor + motherboard) your motherboard id will make it unique. And in case where motherboard id doesn't available only processor id will work (option can be provided). Beside this you can include some extra activation code and generate key with merge serials to make it more complicated.

You are right too. But it isn't safe.
For example i checked it for 10 computers in an institute. I got that all of them have same processor id and haven't motherboard's serial. So they will work by a key. this status may happen in another place.

Google is indeed your a-vote-of-5 friend.

Thanks John, But your link isn't valid.

In what way is it not valid? It shows what you need to do to create a unique id for a machine.

Thanks for your point.
I accept that it shows how i search about hardware_id but his link isn't valid.

You could well be wasting your time.

Given that managed .NET applications can easily be reverse engineered with Reflector[^] and even obfuscated ones with other open source tools such as simple-assembly-explorer[^] it would not be difficult for someone to circumvent your protection scheme.

Shhhhh!! He'll be back asking more questions, and we'll be able to gain some rep points as a result. You're effectively killing the golden goose.

+5 if I could for this response, John...

Sergey Alexandrovich Kryukov 20-Jan-11 21:13pm

Good point, Henry -- my 5.
(John, I don't count how many golden geese I ate already, so I don't care :-)

saeid2010 22-Jan-11 17:19pm

Thanks.I know about Reflector and to obfuscate my application.
But, I am going to get target computer hardware_id and use it in my application's lock.
TNX for your answer
