An event is a subroutine that can be called automatically after a specific operation has occurred.
事件是在具体操作发生之后被自动请求的子程序。
The EndOfRecordset event is triggered when you try to move to a record after the last record in a Recordset. This event can occur if the record pointer is at the end of the Recordset and the MoveNext method is called.
当记录指针试图移动到记录集中最后一条记录之外时，即可触发EndOfRecordset事件。如果记录指针位于记录集的末尾，并且此时你又请求了MoveNext方法，那么此时便激发了EndOfRecordset事件。
Tip: You can use this event to retrieve more records from a database and append them to the end of the Recordset, and then repeat the MoveNext call.
提示：你可以使用该事件从数据库中提取更多的记录，并将它们添加到记录集的末尾，并在此时再次请求MoveNext方法，以再次触发EndOfRecordset事件，以此类推。
Note: Before this method returns, set the status parameter to adStatusUnwantedEvent to prevent subsequent notifications.
注意：在你返回这个方法之前，将status[状态]参数设置为adStatusUnwantedEvent可以阻止接下来一系列的通告提示。
