ACCESS引用ADO 运用OLE DB技术存取数据

VBA给列表框值:
Option Compare Database
Private Sub Form_Load()
    Dim cnnDB As New ADODB.Connection
    Dim RSTobJECT As New ADODB.Recordset
    Dim lbxEmployee As ListBox
    Dim strList As String     
    Set lbxEmployee = Me![员工清单]
    Set cnnDB = CurrentProject.Connection 
    RSTobJECT.Open "tb员工", cnnDB
    strList = "姓名;职称;出生日期;"
    With RSTobJECT
        Do Until .EOF
            strList = strList & !姓名 & ";" & !职称 & ";" _
                      & !出生日期 & ";"
            .MoveNext
        Loop
        .Close
    End With 
    lbxEmployee.RowSource = strList
    Set RSTobJECT = Nothing
    cnnDB.Close
    Set cnnDB = Nothing  
End Sub

   ACCESS引用ADOX，可以定义数据库的内部结构，如表，查询等，
    VBA动态修改传递查询的SQL语句，
    工具-引用,Microsoft ADO Ext. 2.8 for DLL and Security
    Public Sub ChangeSQL(strPassThroughQueryName As String, strPassthroughSQL As String)
    Dim cat As New ADOX.Catalog
    Dim Pro As ADOX.Procedure
    Dim Cmm As New ADODB.Command
    If strPassthroughSQL = "" or Len(strPassthroughSQL) = 0 Then Exit Sub
    Set cat.ActiveConnection = CurrentProject.Connection         
    Set Pro = cat.Procedures(strPassThroughQueryName)
    Set Cmm = Pro.Command
    Cmm.CommandText = strPassthroughSQL
    Set Pro.Command = Cmm
    Set cat = Nothing
    Set Pro = Nothing
    Set Cmm = Nothing
    End Sub
