[resolved] Combobox Autofind

[jcfowl]

We have severe issues with the combobox control in .Net 2003 at work. Basically when you type in something in the combobox it will look like the combobox finds the matching item, but it doesn't. I'm trying to write some AutoFind code to fix this.

Private Sub cmb_KeyUp _
   ( _
   ByVal sender As Object, _
   ByVal e As System.Windows.Forms.KeyEventArgs _
   ) Handles cmb.KeyUp
 
   Call Me.SelectComboboxItem(sender)
   e.Handled = True
 
End Sub
 
Private Sub SelectComboboxItem(ByVal p_cmb As ComboBox)
 
   Dim retVal As Integer
   Dim txtLen As Integer
 
   txtLen = p_cmb.Text.Length
   p_cmb.Tag = p_cmb.Text
   retVal = p_cmb.FindString(p_cmb.Text)
 
   If retVal <> -1 Then
      p_cmb.SelectedIndex = retVal
      'code below is ignored, entire text is selected
      p_cmb.SelectionStart = txtLen
      p_cmb.SelectionLength = p_cmb.Text.Length - txtLen
   End If
 
End Sub

Everything works except the SelectionStart and SelectLength parts. The properties change but when the code actually runs the entire text is selected instead of just selecting the letters that were filled in for the user. Anyone have any ideas on how to make this functionality work?
