The Flush method is used when you need to send the contents of the Stream buffer to the associated underlying object. For example, a node or file represented by the URL that is the source of the Stream object. This will ensure that all changes made to the contents have been written.
Flush的作用是：将记录流缓冲内容发送至与之相关的下一个对象中。举个例子来说：一个用URL来表示的节点或文件就是一个记录流对象的源，这就确保了所有的内容变更信息都会被写进记录流对象源中。

Note: ADO flushes the buffer as much as possible in the background, therefore; it is not usually necessary to call this method.
注意：ADO Flush会释放背景中的整个缓冲器，因此，一般不要使用这个方法。
