In the WPF system (including SL,WP or WIN8) application development, MVVM is a commonplace issue. Beginners may not have feelings, but when you write a core logic that can be ported seamlessly on various platforms, the pleasure cannot be described in words without the need to change the UI.When I first contacted, I did not agree with MVVM, compiled a lot of code, and in turn look at the MVVM for WPF Classic article, only if there is epiphany. The standard MVVM divides the program into model, Vie

In-depth discussion on the ListView control of WPF, wpflistview Next to the previous blog, I initially discussed the ListView control of WPF (involving templates and searching for child controls). We will continue to discuss the usage of ListView. I. Sorting The requirement is as follows: if we put the scores of students into the ListView, we can sort the scores in the single-host ListView header, and change the Xaml as follows:There are not many chan

Technical Discussion and prevention measures for brute-force FTP server crackingWith the development of the Internet, a large number of silly hacking tools have emerged, and the threshold for any hacker attack means has been greatly reduced. However, the creation of brute force cracking tools has become very easy, we usually think that the brute-force cracking attack is only an attack on an FTP server. Is it representative? Can be expanded to other ne

Discussion on Stagefright Vulnerability0x00 Last night, Stagefright reported a major vulnerability, which could cause remote code execution or even sending MMS messages, which may intrude into users' mobile devices. This sounds like a big loophole. As a security personnel, you must take a look at the inside story.0x01 According to the news, for some reasons, the discoverer of the vulnerability has not published relevant details, but has decided to lea

under the./dist/js/page folder.3, Module.loaders is the most critical piece of configuration. It tells Webpack that each type of file needs to be handled using the loader:module: {//Loader ConfigurationLoaders: [//. css files use Style-loader and css-loader to handle{test:/\.css$/, Loader: ' Style-loader!css-loader ' }, //. js files use Jsx-loader to compile processing{test:/\.js$/, Loader: ' Jsx-loader?harmony ' }, //. scss files are compiled with Style-loader, Css-loader

The discovery of this problem is found in the following code:#include After running, we find that the address of the array name itself and the address of the group name are stored exactly the same, we understand the array name as a const pointer (the array name can only be used as an rvalue, not an lvalue), and what is arr?I tried to add the following code to the previous code:printf ("%p\n", arr+1); printf ("%p\n", (arr) +1);It is found in the display window that this shift operation by pointer

Rich Text Editor upload text and pictures and styles, usually in the form of HTML code to the server, when again from the server request this data, echo to the page, with JQ binding data or El expression generally is not a problem, when using the angular front-end schema binding data , sometimes it appears that all the labels are in the front page.The workaround is simple if you are using ng-bind= "any" or {any}, simply replace the binding method with the ng-bind-html= "any" so that the bound da

-MVC, almost any PHP development framework supports the MVC layering model, which has a long history and is a software model designed for programming language Smalltalk in the 80 's, and has been widely quoted.Here is a quote from the Baidu Encyclopedia Image:So I do not introduce the advantages of MVC, search engines can find a lot of relevant information.The title of this article is the HTTP Service seven layer architecture technology discussion, mo

Fireedge evening speech-multi-core multi-thread discussion (Lite version) Multi-core multithreading has become a fashionable topic. As early as 2005, Master herb Sutter of C ++ said that free lunch has ended and the era of concurrent programming has come. It has been the fourth year since the first multi-threaded project. I have been trying to write down the articles in the past few years to minimize the number of people I have come into contact, this

. The analysis ends. From the above we can see that the pointer has two aspects: one is its own value, which is the address in the memory; the other is the object pointed to by the pointer, this address stores data of various meanings. 2. Analysis of pointer values The following example shows the pointer value (a 32-bit computer in the environment ): Void * P = malloc (100); Calculate sizeof (p) =? Char STR [] = "hello"; char * P = STR; Calculate sizeof (p) =? Void func (char STR [1

information must be stored in the database in advance. The Application of regional SMS sending devices, of course, not only refers to the above, but also has related applications in many other industries. When entering a small area, many people will find that they suddenly receive a short message (device contact Q. q: 1780.465.575) What is the principle of sending a lot of such information through a group-sending device? Let's talk about the Principle Analysis of Regional text message devices.
