The Use Limit restricts how many times the user can run the protected software or how many times they may perform a protected action.
The Use Limit is often used to define as a child limit when defining the grace period for an Activation limit or the evaluation period of a Trial limit.
When the license is validated DeployLX checks to see if the uses exceedd the total number of allowed uses and if so will result in a validation failure. How the use count is tracked is determined by the use type.
| At A Time | Tracks the use count each time the application launched. Use the UseExpired event to be notified when the number of uses has been exceeded. |
| Cumulative | Tracks use count from the time that the protected software was first used even between sessions. |
Monitor the use count by requesting an instance of the UseMonitor from the license by calling GetUseMonitor. Then subscribe to the UseExpired event to receive notification when the use count has been exceeded.
Note Uninstalling the software and reinstalling does not reset the use count. To reset the count change the LicenseId of the license or the LimitId of the Use Limit.
The Use Limit supports extensions to authorize continued use of the software after the use count has been reached. This can be used to create a subscription service that requires periodic renewal or to extend the evaluation period of a trial.
Use the Generate Extension Code form to create codes for extending the uses on a users machine.
The limit uses DeployLX's Secure Storage service to track state on the client machine. Secure storage imposes additional security requirements that may require additional configuration
See the Secure Storage topic for more details.
