Serial Data acquisitionThis document describes how to obtain the serial port raw data and parse the raw data into data that can be processed or displayed.First, the serial port collection has many ways:1), MFC has a special control, direct programming acquisition, a control can only collect a serial port, and the serial port name such as COM20 may not open (here I do not practice, senior to say so), the baud rate is too high reading will be wrong.2),
It's been a long time thinking about which programming language programmers should learn first, what programming languages they must master, and how to learn a sequence. Just to see Mr Kim is also studying the first programming language selected who (http://blog.csdn.net/bit
May 2010 List of programming language rankingsLooking closely at the TOP10 of this list, we will find that half of them are dynamic languages: PHP, Visual Basic, Python, Perl, and JavaScript. Today we go into the dynamic language of past life.Trends toward the top 10 programming languagesWhat is dynamic?For dynamic lan

The customer has a system that is frequently connected to us to query data.The previous practice was to give the other party an account so that he could connect to our database for query.
Therefore, early colleagues really gave them DB link stringsThe customer's Windows programs and websites are connected to our compan
The project I was working on needed to use the Subversion feature. I posted this article on Tianya, and I will repeat it here today.
When I configure the header files and dependent libraries required for compiling subversion, the compilation can be passed, but there is always a problem with the link. At that time, I wanted to find a guide document on subversion client API programming. It was very difficult.
The game handles the programming development in two, has explained, in this article will explain to the keyboard simulation.
The simulation of the keyboard, the system has provided a lot of API functions, here is not one to explain, only the simplest of the API functions.

I am also one of the authors of this book, although I only take part in two chapters :)
Google API book: programming, development, and examples is the first complete book in China to introduce Google APIs. It covers all major Google APIs, A large number of instances are used to demonstrate Google API application methods. On the homepage of this book, I chose "G
, Reducebykeyandwindow (_ + , -_, Seconds (5), Seconds (1))See the difference between the two:The first is simple, crude, direct accumulation.And the second way is more elegant and efficient.For example, calculate the cumulative data for t+4 nowThe first way is directly from t+...+ (T+4)The second treatment is that, with the computed (t+3) data Plus (T+4) data, in the minus (t-1) of the data, you can get the same results as the first way, but the intermediate multiplexed three data (t+1,t+2,t+3)
Registry This is a fun thing to do, but it's always a hassle to find what you need in a layer-by-layer containment relationship, and who remembers the path?Anyway, I will not remember, write a small program, let the path saved into the code inside. Release your brain's storage capacity.The individual demonstrates simple programming of the Registry API as an example of an aero effect that opens Windows 8.Pro
DirectX API programming started #01 project settings,
I learned how to use the DirectX API from scratch.
Tutorial: rastertek-> DirectX 11 TutorialsPreparations
1) first, we need a set of software that can write code. I use Microsoft's own IDE: Visual Studio2015

For beginners, a good IDE can indeed improve efficiency. However, it de

allows programmers to use both object-oriented and process-oriented programming patterns in the same program.How to avoid: Under normal circumstances, do not go to Adobe, Google or the game area to work.

Reason for listing: a large number of functions have inconsistent naming conventions, security vulnerabilities, unable to native Unicode, and often mixed in some demo code (such as HTML, CSS).How to avoid this: if you work in the Web, it's h
How is IBATIS sqlmap API programmed? First, when we configure the Sqlmap-config.xml file, we need to parse it, for example:
Java code for IBATIS Sqlmap
public void insert(Person p){ String xml = "com/Jdnis/ibatis/map/sql-map-config.xml"; SqlMapClient sqlMap = null; try { Reader reader = Resources.getResourceAsReader(xml); sqlMap = SqlMapClientBuilder.buildSqlMapClient(reader); sqlMap.startTransaction(); sq
Microsoft has made a lot of interfaces for programming with DirectX brothers. We can see below ildasm that there is only one class named filgraphmanagerclass. In fact, I have read it carefully, there are not many large functions. DirectX is divided into four layers in abstraction,
Hardware/network layer: multimedia devices, including Graphics accelerators, sound cards, input devices, and network communication devices;
DirectX base layer: provides basi
Linux inter-process communication (IPC) programming practices (8) use of shared memory-POSIX shared memory (API)

(2) shared memory area
