如题：
Private Function ADOBatchRst(frm As Form, RecSource As String) As Integer
Dim rs As New ADODB.Recordset
With rs
.CursorLocation = adUseClient
.Open RecSource, sqlcon adOpenStatic, adLockBatchOptimistic Set .ActiveConnection = Nothing ' 断开连接 End With
Set frm.Recordset = rs
' ADOBatchRst = rs.RecordCount
Set rs = Nothing
End Function
以上函数是小宝版主的。
ADOBatchRst me.子窗体.form,"表1"

Open 和 Close 方法范例 (VB)
本范例在已打开的 Recordset 和 Connection 对象上使用 Open 和 Close 方法。
