之前学弟分享的《窗体数据修改历史记录的示例；记录Access字段编辑保存日志的示例；记录字段操作日志【Access软件网】》

http://www.accessoft.com/article-show.asp?id=20823

我给他完善了一下，改成这样会更方便给每个窗体直接调用，改动的代码如下：

Public Function LoadRecordToTag(frm As Object)
         Dim ctl As Control
        For Each ctl In frm.Controls
            If (ctl.ControlType = acComboBox Or ctl.ControlType = acTextBox) And ctl.Name <> "历史记录" And ctl.Name <> "NoCheck" Then
                If frm.Controls(ctl.Name).Locked = False Then
                    frm.Controls(ctl.Name).Tag = "<" & frm.Controls(ctl.Name) & ">"
                End If
            End If
        Next
End Function

Public Function SaveRecordChange(frm As Object, ID As String)
    Dim changeTXT As String
    Dim ctl As Control
    Dim str1 As String
    For Each ctl In frm.Controls
        If (ctl.ControlType = acComboBox Or ctl.ControlType = acTextBox) And ctl.Name <> "历史记录" And ctl.Name <> "NoCheck" Then
            If frm.Controls(ctl.Name).Locked = False Then
                str1 = Trim(frm.Controls(ctl.Name & "_Label").Caption)
                If frm.Controls(ctl.Name).Tag <> "<" & frm.Controls(ctl.Name) & ">" Then
                    changeTXT = changeTXT & str1 & frm.Controls(ctl.Name).Tag & "→<" & frm.Controls(ctl.Name) & ">；"
                End If
            End If
        End If
    Next
         If changeTXT <> "" Then
            Set rst = CurrentDb.OpenRecordset("tbl操作日志", dbOpenDynaset)
            rst.AddNew
            rst!编号 = frm![ID]
            rst!用户 = GetParameter("Current User nickname")
            rst!时间 = Now()
            rst!修改历史 = changeTXT
            rst.Update
            rst.Close
          End If
End Function
        '加载数据到控件tag中，监视是否有修改
         Call LoadRecordToTag(Me)
‘保存
    If Not Me.DataEntry Then
       Call SaveRecordChange(Me, Me![PID])
    End If
