      Dim delimStr As String = " ,.:"
      Dim delimiter() As Char = delimStr.ToCharArray()
      Dim words As String = "one two,three:four."
      Dim split() As String = Nothing

      outputBlock.Text &= "The delimiters are:" & vbCrLf
      For Each ch As Char In delimStr
         outputBlock.Text &= String.Format("   '{0}'", ch) + vbCrLf
      Next
      outputBlock.Text &= vbCrLf

      split = words.Split(delimiter)
      For Each s As String In split
         outputBlock.Text += String.Format("'{0}'", s) & vbCrLf
      Next 
   End Sub
