   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      ' Sets a DateTime to April 3, 2002 of the Gregorian calendar.
      Dim myDT As New DateTime(2002, 4, 3, New GregorianCalendar())

      ' Creates an instance of the HijriCalendar.
      Dim myCal As New HijriCalendar()

      ' Displays the values of the DateTime.
      outputBlock.Text += String.Format("April 3, 2002 of the Gregorian calendar equals the following in the Hijri calendar:") & vbCrLf
      DisplayValues(outputBlock, myCal, myDT)

      ' Adds two years and ten months.
      myDT = myCal.AddYears(myDT, 2)
      myDT = myCal.AddMonths(myDT, 10)

      ' Displays the values of the DateTime.
      outputBlock.Text &= "After adding two years and ten months:" & vbCrLf
