How to learn VB well

One. What is VB?

VB is Visual

Basic programming language.

Writing a computer program requires the use of a computer programming language. Computer programming languages are the bridge between humans and computers. Just like human languages, there are many computer programming languages.

At present, the most widely used languages are "C++", "Pascal", "Basic", etc. Among the many computer programming languages, the basic language is the easiest to learn and use.

Basic is English for Beginner's

allpurpose

symbolic

instruction

The abbreviation of code, which means universal symbol instruction for beginners**, has always been the language of choice for beginner programming applications.

Two. What is the use of learning VB?

VB can do a lot of things, whenever you want to.

Application. Database program. As long as you can think of it, you can basically do it.

However, large and complex programming such as operating systems is now generally programmed in C. It's hard to do with VB. If you want to be a programmer, you can't just know VB.

It's better to learn a little bit more. For example, an asp database. net。

That's how we make better things.

Three. How to learn VB well

VB is an easy-to-learn language, which is typically easy to get started and hard to master.

Today, VB is still the most widely spoken language in the world. The more suitable field is the MIS of the C S architecture, and the derived language VBSict is a very suitable language for the B S architecture MIS, etc., and its simplicity and easy modification are very suitable for the situation of changing management system requirements. The support for the database is also very good, there is MS support in the back, what are you worried about, but any language is evolving, VB is no exception, LZ can be learned on the basis of the present.

.NET architecture, to meet the needs of development.

If you're not a coincidence, I can introduce a way to learn:

1.Read the book first, and have a general understanding of some basic things, no"A blind man touches an elephant"

2.Learn from small things (it's all about practice), e.g. VB

Trigonometric functions. Clock. I think there will be in the book. You can also check out the tutorials on the web.

3.A very important piece of advice: when you have already seen results, it is better to go to a VB advanced tuition school. To use an analogy: if you practice the best, you have to have someone to help you open up the meridians.

4.Suggested books:

1) "Learn Programming by Example--Visual

Basic Programming

Xidian University Press.

2) VB programming tutorial edited by Cao Qing, Qiu Lihua and Guo Zhiqiang published by Machinery Industry Press.

Applications of Real-Time Spectrometers:

1. Analog filters are usually used in noise spectrum analysis, and this kind of filter is used to carry out spectrum measurement and analysis one filter after another. Since there is a certain time constant in the filter and detector circuitry, it usually takes a few seconds to stabilize. Therefore, it takes about 1 minute to complete the entire spectrum analysis with a 1 1 octave filter, and about 3 minutes with a 1 3 octave filter.

This is not a problem at all for stable noises (e.g., machine noise) and the measurement time is relatively generous, but for unstable noises such as environmental noise, traffic noise, and other randomly varying equipment sound sources and impulse noise for a short period of time, the results of spectrum analysis are meaningless. Because the noise during the next filter analysis is completely different from the noise during the previous filter analysis, it only makes sense to choose a real-time spectrum analysis instrument.

2. Real-time, its simple meaning is "instant", that is, the meaning of "immediate sale".

3. The real-time spectrum analysis instrument adopts the digital signal processing method to convert the analog signal into a digital signal.

Spectrum analysis at the measurement edge is very fast, with OCT 1 1x or 1 3 octave or even finer 1 N octave spectrum analysis instantly, FFT analysis, and many other measurement and analysis functions. Because it has so many advantages, it is widely used.
