If the computer is registered in the database, IsIllegalComputer returns false.

If the computer is not registered in the database, the system will try to activate the license on this computer. If all available activations are already consumed, the activation will fail and IsIllegalComputer will return true. If there are unused activations, this computer will be activated and IsIllegalComputer will return false.

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
