                     string computerID,
                     string computerKey, 
                     bool logRelease, 
                     out string response)

Parameters

Parameter	Type	Description
webServiceUrl	string	URL to the QLM License Server
activationKey	string	the license key to deactivate
computerID	string	the unique computer identifier
computerKey	string	the computer key being released
logRelease	long	flag that determines whether the release will be logged in the history table. If you are using cloud based floating licenses, you should set this argument to false to prevent bloating of the history table.

Remarks

You can control how many times a user can release a license with the following Server Properties:

• maxReleaseCount: The maximum number of times an end-user can release a license.
• maxReleasePeriodInDays: When counting the number of released licenses, only count the ones that have been released in the past "maxReleasePeriodInDays" days. For example, if you want to allow a user to release a license twice per month, set maxReleasePeriodInDays to 30 and maxReleaseCount to 2.
• maxReleasePerClient: When counting the number of released licenses for a given activation key, count only the ones associated with a specific client. By default, QLM counts all the released licenses for a given activation regardless of the client system.

By default, you must set the CommunicationEncryptionKey before calling ReleaseLicense. The server property releaseLicenseUseAdminEncryptionKey can be used to configure the server to require the AdminEncryption to be set in order to call ReleaseLicense.

Use ParseResults to interpret the results of the call and load the returned data into an ILicenseInfo object.

C#

ILicenseInfo li = new LicenseInfo();
string message = string.Empty;
if (lv.QlmLicenseObject.ParseResults(response, ref li, ref message))
{
  // The operation  was successful	
}
else
{
  // The operation failed
}
