Xml| Programming | Application Example This article introduces 3 basic examples of XML that are designed to lead you quickly into the world of XML programming. Examples include: in. NET using XML, reading XML files, inserting data into XML documents. 　　using XML in. NETIf you have used MSXML3, then in. NET application will be a fairly straightforward process. Ins

Of course, there are some problems I can not solve.After running, I can read and display the information of my database, but I show it this way:There is garbled problem, I also found on the Internet a lo

OpenGL ES2.0 API inherits OpenGL's C-s (client-server) mode. Application (client) to publish the command, the server is responsible for performing the processing. And not every command issued by the application is sent to the server in a timely manner. The CPU in the device is responsible for running the game logic and sending the drawing instructions to the GPU (hardware graphics or software-emulated graphics cards). In this architecture, the CPU and the GPU act as client and server roles, res

1. Single Duty: A class, only need to do one thing 2. Development closure: A class that should be extensible and non-modifiable 3. Dependency inversion: A class that should not be strongly dependent on another class. Each class is replaceable for another class. 4. Configure: Use the configuration as much as possible, not hard-coded. 5. Interface-Oriented programming: Only care about the interface, do not need to care about the implementation.From for

Introduction to basic socket programming in Python, pythonsocket In network communication, sockets are almost everywhere. It can be seen as an intermediate software abstraction layer for communications between the application layer and the TCP/IP protocol cluster. It is an interface for two applications to communicate with each other, in addition, the complex TCP/IP protocol details are hidden behind the in
