>1) To be able to check for concurrent users.
>2) To be able to check for number of installations or have a scheme to ensure when a user buys 4 liscences
>they can install four applications.

>I could get by perhaps with only the number of concurrent users.

>My idea: Develope a simple code scheme:

>example 12345-123456-A2566 (where I select one particular field to be the field that contains the number of concurrent users)
>Each time the app is started I chekc this value against the number of logged in users which I currently can do.

>Any ideas for a coding scheme?

>Also where would be best to store this key?
>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?
