Looping through a Listviews SubItems?

Is there a way to loop through a ListViews SubItems property to Add SubItems. I'd like my program not to have to know in advance how many SubItems to add(to find out in execution, then process). Also why if I use the DOEVENTS it takes twice as long to open the DB?

Code:

---

Option Explicit
Private conn As ADODB.Connection


Private Sub Load_list()


Dim itemX As ListItem
Dim rs As ADODB.Recordset
Dim i As Integer
Dim intCounter As Integer ' Counter to set Progressbar.Value
    'Create New connection
    Set conn = New ADODB.Connection
    conn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\Biblio.mdb"

    Dim w As Integer ' add this line
    w = 0 ' this one

    'Open the Titles table
    Set rs = New ADODB.Recordset
   
    rs.Open "Titles", conn, adOpenKeyset, adLockPessimistic
   
    rs.MoveLast
    rs.MoveFirst
    With prgLoad
        .Max = rs.RecordCount
        .Visible = True
    End With
    ListView1.View = lvwReport
       
    For i = 1 To rs.Fields.Count
        ListView1.ColumnHeaders.Add , , rs.Fields(w).Name ' alter this
        w = w + 1 ' add this
    Next i
 Do Until rs.EOF
 intCounter = intCounter + 1
        prgLoad.Value = intCounter ' Update ProgressBar.
        Set itemX = ListView1.ListItems.Add(, , rs.Fields(0))
        itemX.SubItems(1) = rs.Fields(1)
        itemX.SubItems(2) = rs.Fields(2)
        itemX.SubItems(3) = rs.Fields(3)
        itemX.SubItems(4) = rs.Fields(4)
        Set itemX = Nothing
        rs.MoveNext
        DoEvents
  Loop
    ' Hide Progressbar
    prgLoad.Visible = False
    rs.Close
    conn.Close
    Set rs = Nothing
    Set conn = Nothing
 

End Sub



Private Sub Command1_Click()
Call Load_list
End Sub

Private Sub Form_Unload(Cancel As Integer)
    Unload Me
End Sub

Private Sub mnuExit_Click()
    Form_Unload
End Sub
