You must call DefineProduct before calling this function.

This function can be used to activate a license when the Activation Key is not known. For example, you can use this function to activate a license based on an Order ID. To do so, you set the fieldName argument to "OrderID" and set the fieldValue argument to the value of the Order ID.

By default, the supported fields are: OrderID and ReceiptID.

You can modify the list of supported fields by updating the activationByFieldAllowedFields setting in the QLM License Server's web.config file.

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

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