A little insight into the project

Recently, I found out that some things are hard to learn and can be used. In fact, you have never studied these things in depth, it may take a while to change from usable to usable. For example, if you do not read the attributes and functions of some controls, you only know that they are available, I feel like I can use it. In fact, you are also confused when using it. Some of the mechanisms in it do not know what is going on ~ As I have said again, how many books can be explained clearly, and how many other books are fully covered? I feel the best book and the help documentation provided by the development tool. Although they are all in English, I am not very good at English, but what are some good helpers for Google translation, in the future, remember: Let's take petabytes for example, if there is no difference between F1 and F1 in the book, it must not be said. Of course, the above F1 prevails ~
