Begin finding in list box when you begin typing in Textbox Without any API use. Very easy and with only one procedure...!
API Declarations
Public Function IndexFromText(lb As ListBox, sFind As String, Optional bCaseSensitive As Boolean = False, Optional bMatchFull As Boolean = False, Optional bNoneOnBlank As Boolean = False, Optional lOUT_Error As Long = 0) As Long
On Error GoTo errIFT
Dim l As Long, lLen As Long
Dim s As String
IndexFromText = -2
If lb Is Nothing Then Exit Function
If lb.ListCount = 0 Then Exit Function
If sFind = "" Then
If bNoneOnBlank Then IndexFromText = -1
Exit Function
End If
lLen = Len(sFind)
For l = 0 To lb.ListCount - 1
s = lb.List(l)
If Len(s) >= lLen Then
If bCaseSensitive Then
If bMatchFull Then
If s = sFind Then
IndexFromText = l
Exit For
End If
Else
If Left(s, lLen) = sFind Then
IndexFromText = l
Exit For
End If

errIFT:
lOUT_Error = Err.Number
Err.Clear
IndexFromText = -3
