【译文】如何判断当前的记录在窗体里是否是一个新记录

      下面的例子展示了如何使用NewRecord属性来确定当前的记录是一个新的记录。把NewRecordMark程序集的当前记录赋值到变量intnewrec。 如果记录是新的,就发一个消息通知用户。你可以把这个过程当写在窗体的当前事件中。

VBA代码：

Sub NewRecordMark(frm As Form)
    Dim intnewrec As Integer
 
    intnewrec = frm.NewRecord
    If intnewrec = True Then
    MsgBox "一条新纪录" _
        & "@你想增加一条新纪录吗?" _
        & "@如果不要，移到现有记录"
    End If
End Sub

原文：How to: Determine Whether The Current Record is a New Record In a Form

      The following example shows how to use the NewRecord property to determine if the current record is a new record. The NewRecordMark procedure sets the current record to the variable intnewrec. If the record is new, a message notifies the user. You could call this procedure when the Current event for a form occurs.

VBA
Sub NewRecordMark(frm As Form)
    Dim intnewrec As Integer
 
    intnewrec = frm.NewRecord
    If intnewrec = True Then
    MsgBox "You're in a new record." _
        & "@Do you want to add new data?" _
        & "@If not, move to an existing record."
    End If

End Su
