[AccessD] overflow

Hello Stuart,

i changed the code (see below), but now it isn't working.
After clicking the button, nothing happens. The second time clicking the 
button, the first word of the text is selected, the third time clicking, i 
get an error: Run-time error 5, invalid procedure call or argument.

Pedro


------code----------------
Private Sub cmdSearch_Click()

   If dummy <> "" Then
      tekstplaats = plaats
      If tekstplaats = 0 Then
         tekstplaats = 1
      End If
      INHOUD.SetFocus

      plaats = INHOUD.SelStart + Len(dummy) + 1
      plaats = InStr(tekstplaats + 1, INHOUD, dummy, 1)
      If plaats > 32767 Then
      plaats = plaats - 65536
      INHOUD.SelLength = Len(dummy)
      Else
         INHOUD.SelStart = 0
         INHOUD.SelLength = 0
      End If
      tekstplaats = plaats
    Else
       MsgBox "Kan geen lege tekst zoeken !!", 16, "Tekst zoeken"
    End If

End Sub
