Imports System.Globalization

Public Module Example
   Public Sub Demo(outputBlock As System.Windows.Controls.TextBlock)
      ' Create a read-write NumberFormatInfo object for the current culture.
      Dim numberInfo As NumberFormatInfo = DirectCast(NumberFormatInfo.CurrentInfo.Clone, _
                                                      NumberFormatInfo)
      Dim value As Decimal = -16.32d

      ' Assign each possible value to the CurrencyNegativePattern property.
      For ctr As Integer = 0 to 15
         numberInfo.CurrencyNegativePattern = ctr
         outputBlock.Text += String.Format("{0,2}: {1}", ctr, _
                                           value.ToString("C", numberInfo)) + vbCrLf
      Next
   End Sub
End Module
' The example displays the following output:
'        0: ($16.32)
'        1: -$16.32
'        2: $-16.32
'        3: $16.32-
'        4: (16.32$)
'        5: -16.32$
'        6: 16.32-$

'       11: $ 16.32-
'       12: $ -16.32
'       13: 16.32- $
'       14: ($ 16.32)
'       15: (16.32 $)
