Protect a service

If your application runs as a service, say a Windows Service, you can protect your application with QLM as follows:

In your service application, add license validation when the service starts. If you use the LicenseValdiator class generated by the "Protect your application" wizard, call ValidateLicenseAtStartup when your service starts. If the call to ValidateLicenseAtStart up fails, you have two options:

1. Log an event in the Event Viewer with the error message returned by ValdiateLicenseAtStartup. The user would then need to launch the QLM License Wizard standalone application (with the proper arguments) to allow him/her to enter a license key.
2. Launch the QLM License Wizard standalone application (with the proper arguments) to allow the user to enter his license key. This may not be possible if your service does not have privileges to launch a desktop app.
