1、The gravest obstacle（最大障礙） of study is tolerating（忍受）. The first step is finding the problem,we should stand up when we can't hear clear or understand on the class
2、When you solve a engineering problem ,you should use “save as（另存爲）“ timely. It can help you refind（改進） the case you have made ,and remind you never let it go second time.
3、“DINNER THEORY（喫飯理論）”：when you have dinner with 9 unfamiliar people ,you can’t be in with them. Undoubtfully, you will take every chance to escape;But,if there is only a man you don’t familiar with ,so you will be frank with him ,and soon he will be your new friend. It can apply to your study :when you faced with a lot of bugs, don’ t be afraid ,just sort them one by one .
4、“THIEF THEORY”(配貨站理論、順便觀察法):When you get an software，the observing must come first. For example, when you use a component’ one property, you should have a look at the other properties at the same time
5、Variable include the unusual Variable and the Variable definated by yourself.
自定義數據類型：把一個對象的不同屬性作爲一個整體（它與記錄數組不同），打包成一個自定義數據類型變量，它是對象的一個雛形，真正的對象還包括方法、事件··
6、About the order in learning VB：
石小勇：如何在VB內部運動API viewer 時，直接讓它加載一個文本文件，而不是每次都需要手動加載一個···· The difference between investigation（研究學） and engineering（工程學）：The computer science belong to the second，which attach more importance to the result than the process.In other way,our goal is the “ROME” not the “ROAD”.wo must take macroscopic view (宏觀角度) about VB and fix our targets（明確目標）。
7、About the file system（文件系統）:
Zhaojunyan and Lishouhong can’t understand what this chapter is designed for ····In my opinion ，the process we run the program is the same as the the program is running by the users ,so this chapter is serving us ,we design the process ,the module(模塊),the program ;what all we have done was serving the users .
From their problem ，we can judge that they don’t comprehend(理解) this chapter thoroughly（徹底地；透徹地）.when we start an new chaper ,wo should making it chear that ：
What’s the relation between this chapter and this book;
The contents of the chapter;
The effect of this chapter in the book;
How to use this contents;
When to use this contents;
How to deal with the detail points(細節的知識點)。
8、The “shortcut” of learning: algorithm（算法） has much relations with mathemitics（數學）. So we shouldn’t take them apart.Don’t drop you pencil away,when you faced with you PC。
