The CancelBatch method cancels a batch update. The Recordset must be in batch update mode when calling this method.
CancelBatch的作用是：取消批量更新。当请求该方法时，记录集必须处于“批量更新”模式下。
Since you do not know what the current record will be after calling this property, you will have to move to a known record. For example, you could call the MoveFirst or MoveLast method, after a call to this method.
因为你在请求这个属性之后不会知道当前记录的具体是哪条，所以你不得不移动到一个未知的记录上。举个例子来说，你可以在请求该方法之后请求MoveFirst 或 MoveLast方法。
If this method fails, the provider will not stop the execution, but it will send a warning to the Errors Collection.
如果这个方法执行失败，那么技术提供对象[provider]不会停止执行程序，但是它将向Error[错误]集中发送一个警告信息。
