changing text color on the fly

I have a rich text box that a whole bunch of text gets poured into, I want this text box to check to see if the word "private" is typed in, if it is I want it changed to blue. Any idea how to do this?

Code:

---

Private Sub RichTextBox1_Change()

    Static lngStart As Long
    Dim lngFound As Long
    Dim intLen As Integer
    Const LOOK_FOR = "PRIVATE"
   
    intLen = Len(LOOK_FOR)
   
    If lngStart = 0 Then
        lngStart = 1
    End If
   
    lngFound = InStr(lngStart, UCase(RichTextBox1.Text), LOOK_FOR)
   
    If lngFound > 0 Then
        RichTextBox1.SelStart = lngFound - 1
        RichTextBox1.SelLength = lngFound + intLen
        RichTextBox1.SelColor = vbBlue
        RichTextBox1.SelStart = lngFound + intLen + 1
        RichTextBox1.SelColor = vbBlack
        lngStart = lngFound + intLen
    End If
   
End Sub
