Example
This example publishes Analytics to the License Server. The QlmAnalytics object is first initialized using a QlmLicense object. We then check if there's an InstallID already registered on the system. If no InstallID is found, we add this computer as a new installation. Otherwise, we simply update the data of the existing installation.
// license is an instance of a QlmLicense object. When using the LicenseValidator class, // you should use licenseValidator.QlmLicenseObject.try{QlmAnalytics analytics =newQlmAnalytics(license);string errorMessage;string installID =analytics.ReadInstallID(out errorMessage);AssemblyName assemblyName =Assembly.GetEntryAssembly().GetName();string version =assemblyName.Version.ToString();if (String.IsNullOrEmpty(installID)) {bool ret =analytics.AddInstallEx(version,analytics.GetOperatingSystem(),Environment.MachineName, computerID, activationKey,this.computerKey,license.IsEvaluation(),license.ProductName,license.MajorVersion,license.MinorVersion, customData1, customData2, customData3,ref installID);if (ret ==true) {analytics.WriteInstallID(installID,out errorMessage); } }else {analytics.UpdateInstallEx(installID, version,analytics.GetOperatingSystem(),Environment.MachineName, computerID, activationKey,this.computerKey,license.IsEvaluation(),license.ProductName,license.MajorVersion,license.MinorVersion, customData1, customData2, customData3 ); }}catch (Exception ex){Console.WriteLine(ex.Message);}
