Imports System.Globalization

Module Example
   Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      Dim cal As New UmAlQuraCalendar()
      Dim currentYear As Integer = cal.GetYear(Date.Now)

      outputBlock.Text &= "Era     Year     Days" & vbCrLf
      outputBlock.Text &= vbCrLf
      For Each era As Integer In cal.Eras
         For year As Integer = currentYear To currentYear + 9
            outputBlock.Text += String.Format("{0}{1}      {2}      {3}",  
                              ShowCurrentEra(cal, era), era, year, 
                              cal.GetDaysInYear(year, era)) & vbCrLf  
         Next
      Next
      outputBlock.Text &= vbCrLf
      outputBlock.Text &= "   * Indicates the current era." & vbCrLf
   End Sub

   Private Function ShowCurrentEra(ByVal cal As Calendar, ByVal era As Integer) As String
      If era = cal.Eras(Calendar.CurrentEra) Then
         Return "*"
      Else
         Return " "
      End If
   End Function
End Module
