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 = -0.1324d

      ' Assign each possible value to the PercentNegativePattern property.
      For ctr As Integer = 0 to 11
         numberInfo.PercentNegativePattern = ctr
         outputBlock.Text += String.Format("{0,2}: {1}", _
                                           ctr, value.ToString("P", numberInfo)) + vbCrLf
      Next
   End Sub
End Module
