>Each time the app is started I chekc this value against the number of logged in users which I currently can do.

>My ideas:
>1)Store it an the database a some unlogical field exmaple named xjkxj=.t. where they would never guess it was the liscence key.
>2)Store it in an unlogically named registry key.

>As for the number of installed applications I have no ideas about how to check for this.

>My major questions are again:
>1) Where to store the key?
>2) What is a good coding scheme to use.
>3) Is there any third party tools that address this.
>4) How can I check for number of installations?
