Software Registration Technique

P: n/a
Hi all,

Merry Christmas!

I would like to have trial period for my .NET application and let user to
enter S/N for registration. I would like to ask how can we store the
registration status of the user. Currently, I use isolatedStorage to store
the info e.g. the date of start trial, the date of registration, user name
etc.. However, I know it is not secure enough. Where and how do you store
the registration info? Any web site tutorial teach this?

I read this article http://windowsforms.net/articles/Licensing.aspx, but
seems cannot help me.

Thanks,
Jason

Lately I have seen Nick (Nak) very active with this however he has I thought
still questions himself.

Maybe you can have a look what is written in this newsgroup about isolated
storage already.

Hi Cor,

I can successfully use isolatedStorage now. However, I just think it is not
a good way for storing registration info because it may easily edited by
others. Just want to know how other developer save the registration info for
their applications and protect their IP.
