. comer's "using TCP/IP for Internet interconnection" Volume 1, learn about the network, and then look at the first volume of "UNP", not only learning network programming, but also some common techniques of System ProgrammingI am very familiar with it. If you continue network programming, we suggest you read the third volume of "TCP/IP for Internet interconnection", which contains a lot of programming on the application protocol telnet, FTP and other protocols.If you want to write a device drive

I have read three books one after another, including WPF Unleashed, Application = Code + Markup and Programing WPF, but I have not read any of them. I will first look at the previous chapters, and then I will go over the chapters that interest me. Among all the WPF books, many people have the highest rating on WPF Unleashed, but in my personal sense, I prefer Programing WPF. Because the former is indeed a b

abstraction capabilities of the software deployment architecture.4, over reactiveBecause of Facebook's react.js, it has become popular in the last 2 years. Interestingly, React.js's popularity is not because of its React architecture, but because it first adopted the virtual DOM, separating the DOM structure you want from the real DOM structure and handing it over to a framework to deal with the differences between the two. This and the 60, 70 's, you directly handwritten assembly and through t

about "C with classes". I didn't write several classes, but I wrote code in process-oriented mode. process-oriented mode won't make authentic C, so I got myself in this situation and thought it would be better to take C seriously and check it out. Which of the following is the problem? How can I create a project that only contains C files in vc6.0, I really don't know. I have been searching for a long time in the project, and I can't try to create a new one. At first, I had to create new-> C/C

A good question is also very useful and has made several mistakes. 1. Thinking has an error in enumeration assignment: when the current assignment cannot be completed, it should be to continue the next loop, rather than return false to terminate the enumeration. 2. The generic programing is wrong. Originally, the memset wanted to be written as the generic programing. Then, there will always be only the firs
