如果自己花好几天时间写好了一个vbs程序。只要给别人用，就一定可以被别人看到vbs源代码，别人想怎么修改就怎么修改。我们需要给自己的vbs程序加密。(If you spend a few days to write a VBS program. As long as it is used for others, it is sure that the source code of VBS can be seen by others, and how to modify it if others want to modify it. We need to encrypt our own VBS programs.)
