Look Ahead Combo Box

;)

I got this code here at VB-World and it's suppose to allow the User to enter a string and it will find the match or at least the nearest match of the string in the Combo Box.

Private Const CB_FINDSTRING = &H14C
Private Const CB_ERR = (-1)
Private Declare Function sendMessage Lib "user32" Alias "SendMessageA" (ByVal hWnd As Long, wMsg As Long, ByVal wParam As Long, IParam As Any) As Long

Public Function autoFind(ByRef refComboBox As ComboBox, ByVal KeyAscii As Integer, Optional ByVal LimitToList As Boolean = False) As Long
Dim ICB As Long
Dim sFindString As String
If (KeyAscii = 8) Then
If (refComboBox.SelStart <= 1) Then
refComboBox = ""
autoFind = 0
Exit Function
End If
If (refComboBox.SelLength = 0) Then
sFindString = UCase(Left(refComboBox, Len(refComboBox) - 1))
Else
sFindString = Left$(refComboBox.Text, refComboBox.SelStart - 1)
End If
ElseIf ((KeyAscii < 32) Or (KeyAscii > 127)) Then
Exit Function
Else
If (refComboBox.SelLength = 0) Then
sFindString = UCase(refComboBox.Text & Chr$(KeyAscii))
Else
sFindString = Left$(refComboBox.Text, refComboBox.SelStart) & Chr$(KeyAscii)
End If
End If
ICB = sendMessage(refComboBox.hWnd, CB_FINDSTRING, -1, ByVal sFindString)
If (ICB <> CB_ERR) Then
refComboBox.ListIndex = ICB
refComboBox.SelStart = Len(sFindString)
refComboBox.SelLength = Len(refComboBox.Text) - refComboBox.SelStart
autoFind = 0
Else
If (LimitToList) Then
autoFind = 0
Else
autoFind = KeyAscii
End If
End If
End Function

What happens though is, whatever I type in, the only string I receive in return is the first item in the Combo Box.

Please help.

Thanks.
