Create a hexadecimal value out of range of the Integer type.

 

Module Example
   Public Sub Main()

        Dim sourceNumber As Long = CLng(Integer.MaxValue) + 1
        Dim isNegative As Boolean = (Math.Sign(sourceNumber) = -1)
        Dim value As String = Convert.ToString(sourceNumber, 16)
        Dim targetNumber As Integer
        Try
           targetNumber = Convert.ToInt32(value, 16)
           If Not isNegative And ((targetNumber And &H80000000) <> 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 integer.", value)
        End Try 
   End Sub
End Module
