[Super Simple VB Introduction] I. Written in Front

Preface

Every book has to have something written at the front, and of course I can't be an exception. Prefaces are a case of “existence is reason enough,” so I'll just write a little~

First of all this book is prepared for kids who have never touched programming. Because my knowledge is shallow and I only half-understand VB, I can only cover a little of the most basic knowledge. After getting started you can freely learn more advanced things~

Programming actually isn't hard. A lot of people freeze up the moment they see dense code filling the screen= =…

Plenty of kids also ask me whether programming means memorizing lots of code= =… Actually you don't need to memorize at all. The English words involved in programming are all very simple; high-school English is basically enough. Of course if your English is good enough that you can read the original English manuals, that's even better. The English words involved in programming are simple vocabulary such as: if while for end begin function, so kids don't need to be afraid.

Besides English there's also the math issue. Some students may have looked at some programming textbooks and been scared by all the math problems inside= =… Indeed, programming was originally invented to replace human labor for large amounts of calculation, but! Times are different now. Any phone we casually pull out can perform hundreds of millions of calculations. Do we still need to write programs ourselves to do arithmetic= =… Besides, we're not mathematicians and don't need to calculate those things (anyway I can't figure out what use it is to program things like the Tower of Hanoi or the Eight Queens; those are for training algorithms, and for getting started we can skip that kind of thing). We program now mainly to develop practical software. What is practical software? Software that can actually produce something real. Calculating those messy math problems simply make no sense= =…

The image below is a fractal graphic I wrote in C#, based on a problem in a book. The result is this pitch-black thing, which is completely useless

Fractal graphics involve math, right? But in everyday computer use, who would actually mess with this= =… So to sum up, you don't need to be afraid of English or math, because very little of either is involved, unless you study very deeply—but by then you won't be afraid of these things anyway, right~

Below I'll show you kids some other more practical software= =…

Project Manager

This is software developed in C#, used to manage the projects I'm currently developing. It hasn't been open-sourced yet, so students who want to know more can contact me via the WeChat official account.

PassNote Password Notebook

A password management app developed in C#, saved using the AES encryption algorithm. You can generate passwords and save passwords in the software. The code has been open-sourced. Interested students can click here: PassNote Homepage

Voice Countdown

This is a countdown reminder app I wrote in vb. Project homepage: http://blog.deali.cn/works/qcountdown

After setting it to start automatically on boot. Every time you start up, it displays a countdown of the nearest event on the desktop, and gives a voice prompt. Like this:

Ratio Conversion

This is a super simple sample app I wrote in vb, used to demonstrate the CQAF framework (a rapid software-building framework I developed based on VB)

Everything introduced above is desktop software on the PC. The PC side is only the tip of the iceberg of software development. Besides that, there are all kinds of programs on the web, the server side, and mobile. Due to space limits, and because this tutorial is mainly about PC-side development, I won't introduce those here. Interested students can find the corresponding information on my blog. Or you can contact me via the WeChat official account. Later as the introductory tutorial proceeds, I'll show you kids more examples~

I've rambled on enough; the words written in front are done. Next I hope you kids keep your interest in programming and keep learning—you'll pick it up before long!
