如何使用ADO取得每個Tables,View的名稱(編號:619)

我使用以下程式碼,想要取得每個Table,View的名稱
Dim adoConn As New ADODB.Connection
Dim strConn, strSQL As String
  Dim cat As New ADOX.Catalog
  Dim tbl As New Table
  Dim qef As ADOX.View

strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\ChangeMan.mdb;Persist Security Info=False"
  adoConn.Open strConn
  Set cat.ActiveConnection = adoConn
  
  For Each tbl In cat.Tables
    MsgBox tbl.Name
  Next

但結果會連同系統Table,view都列出,請問如何只取得自建的Table及view
