说明：  在IE的工具栏上加个按钮。有很多程序喜欢装完了之后在ie上加个按牛，使别人点了之后运行他们自己的程序，方便大家使用他的程序，我们也可以这么做，这个代码教你怎么实现。
(in IE toolbar add buttons. There are many procedures like after the Flight ie by adding 000 cattle and allow others to the point after running their own procedures to facilitate the use of the procedure, we can also do so, the code will teach you how to achieve.)
