"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Use this function, you call it with code like

  Number_of_words_in_richtextbox = CountWords(The_name_of_the_richtextbox.Text)

Function CountWords(Text As String) As Long

  Dim NrTecken As Long
  Dim OldNrTecken As Long
  Dim Char As String
  CountChar = 0
  OldNrTecken = 1
  NrTecken = InStr(Text, " ")
  Do Until (NrTecken = 0)
    If (NrTecken > OldNrTecken + 1) Then
      CountWords = CountWords + 1
    End If
    OldNrTecken = NrTecken
    NrTecken = InStr(NrTecken + 1, Text, " ")

End Function
