WriteInstallID

Description

Writes the installID into a QLM cookie on the end user system. To read keys, use the ReadInstallID API.

Note that to call this function, you must initialize the QlmAnalytics object with the following properties:

• WebServiceUrl

• CommunicationEncryptionKey

• GUID (persistence key)

 bool WriteInstallID(string installID, out string errorMessage)

Parameters

Parameter	Type	Description
installID	string	unique identifier of this installation, returned by a call to AddInstall
errorMessage	string	returned error message containing details about the failure, if any.

Return

Type	Description
Boolean	true if the operation was successful; otherwise, false.

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 = new QlmAnalytics(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
