嗨，我需要一些幫助。我接受了一個商業智能項目的任務，其中第一步是記錄用戶的入口和出口日期和時間。所以我有三個模塊： modCaptureIns和modCaptureOuts;另外，當隱藏窗體frmCaptureOuts關閉時（在用戶關閉數據庫時），我在AutoExec宏和modCaptureOuts上運行了modCaptureIns函數RecordIns（）。MS Access日誌記錄用戶網絡入口和出口時間
這是問題：當一個用戶打開和關閉數據庫入口和退出時間記錄在tblInsNOuts。只要您有多個用戶，第二個用戶將SessId變量更改爲不同的數字，然後不記錄退出時間。請給我一個手。任何幫助都感激不盡。
