   Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      Dim pattern As String = "\b(\S+?)\b"
      Dim input As String = "This sentence is rather short but pointless."

      Dim matches As MatchCollection = Regex.Matches(input, pattern)
      Dim words(matches.Count * 2 - 1) As Object

      Dim index As Integer = 0
      For Each match As Match In matches
         match.Groups.CopyTo(words, index)
         index += 2
      Next
      ' Display captured groups.
