Hi friends,
i'm publishing a simple application for windows,
users buy a license key and they entered in application to register it and use it.
now i want to check the users !
for instance when they open my application, it automatically connects to my web site ( or server, or anywhere else ) and check the registration key, if the key is invalid, so the application block itself !
I think some windows applications do like this, isn't it ? if you registered them with invalid keys, it'll be detected when you connect to internet and open the application !
any idea to implement this scenario !?
thanks in advance.
