Question <Newbie Ask> How to make a registration form for an application ?

[capedech]

Hi,
I am really really newbie about security.

I just make a small Retail POS application for my parents shop. And it almost finnished. I want to make a Registration form for my application so that if someone somehow got my program, he couldn't use it.
I am thinking to make a lisence key for my program to run and go or to give a message box and go to registration form.
No need to make trial version, 'coz only my parents are the only costumers ^.^.

So, in my limited knowledges about registration, I know that it will need encriptions and decriptions and the lisence key numbers need to be saved in the Windows Registry.
My friend said to use computer id or something to make the lisence key.

I am thinking to make another application just to do the generate the password.

Please help me.

Thanks in Advance.

Hi,

I assume that you are going to install your software only to your parent's pc (Assuming only 1 PC).

Instead of using computer ID as said by your friend, you may use Processor S/N.

On your application load, validate it and only allow to continue if pass.

Means that, this application was unable to run even someone got the installer and install to their pc.

Hope ths help.

cheers....

@jacky.goy
Thanks for the advice. It really helps.
But I need the registration more flexible, 'coz soon my parents will open a branch of their shop.
And for that reason, I am thinking to make another program just for generating the serial number.
