        Dim targetNumber As UInt16
        Try
           targetNumber = Convert.ToUInt16(value, 16)
           If isSigned And ((targetNumber And &H8000) <> 0) Then
              Throw New OverflowException()
           Else 
              Console.WriteLine("0x{0} converts to {1}.", value, targetNumber)
           End If    
        Catch e As OverflowException
           Console.WriteLine("Unable to convert '0x{0}' to an unsigned short integer.", _
