   Okay as discussed, here my example code that will let the user run through the Windows error codes by using the C++11 random generators - because rand() must not be used anymore!
   Here's the list btw: http://msdn.microsoft.com/en-us/library/windows/desktop/ms681382(v=vs.85).aspx

      #include <chrono>
      #include <random>
   
      unsigned long ulError = GetLastError(); // Get the error in this way
   
      // Setup the random number generator
       unsigned seed = std::chrono::system_clock::now().time_since_epoch().count();
       std::default_random_engine generator(seed);
       std::uniform_int_distribution<unsigned short> distribution (0, 15999); // Range of the Windows Error Codes
       unsigned short rand_error = distribution (generator);
   
       fmt::WindowsError gimmError (rand_error, " TestError: ");
       cerr << "\n***ERROR (" << rand_error << ")" << gimmError.what();

   Output if you enter a number that is not a Windows error code: ***ERROR (6449) TestError: error code = 6449

   Added examples, but still need to clarify what happens if you pass an invalid error code.
