Try byteVal = System.Convert.ToByte(longVal) outputBlock.Text &= String.Format("{0} as a Byte is {1}", _ longVal, byteVal) & vbCrLf Catch exception As System.OverflowException outputBlock.Text &= String.Format( _ "Overflow in Long-to-Byte conversion.") & vbCrLf End Try ' A conversion from Byte to Long cannot overflow. longVal = System.Convert.ToInt64(byteVal) outputBlock.Text &= String.Format("{0} as an Long is {1}", _ byteVal, longVal) & vbCrLf End Sub
