ValidateLicenseFile

Validates a license on the server

Description

Validates a QLM license file by performing the following operations:

• Reads the license file and validates its signature
• Validates the license based on the information in the license file
• If server-side validation is enabled, contacts the License Server and validates the license on the server
• If needed, reactivates the license to retrieve the latest information from the server

ELicenseBinding licenseBinding = ELicenseBinding.ComputerName;
ILicenseInfo licenseInfo;

if (!String.IsNullOrEmpty(lv.QlmLicenseObject.LicenseFilePath))
{
  licenseFile = Environment.ExpandEnvironmentVariables(lv.QlmLicenseObject.LicenseFilePath);
}

bool ret = lv.QlmLicenseObject.ValidateLicenseFile(lv.QlmLicenseObject.DefaultWebServiceUrl, 
                                                   licenseFile, string.Empty, string.Empty,
