application life cycle

When an ASP. NET page runs, this page goes through a life cycle, and a series of processing steps are performed during the life cycle. These steps include initializing, instantiating the control, restoring and maintaining the state, running the event handler code, and rendering. It is important to understand the

The purpose of this article is to describe in detail every process that ASP. NET MVC requests from start to finish.I want to understand anything that happens after the browser enters a URL and taps enter to request a page for an ASP. NET MVC site. Why do you need to care about this? There are two reasons. The first is that ASP. NET MVC is a very extensible framework. For example, we can insert different viewengine to control how the site content is rendered. We can also define how the controller

uiapplication class in your program (it is not recommended to inherit the UIApplication class to establish a custom subclass), you need to pass in your custom class name as the 3rd parameter.Each iOS application contains an UIApplication object that the iOS system uses to monitor the entire application life cycle.

Many applications are now developed based on nested fragment in fragmentactivity, so if we can clearly know their life cycle, it will make our development easier.For the life cycle of the activity, I have already described it in detail in the previous article Activity life

can use the management project as the parent node directly. Example:Because the above practices will cause all projects that inherit this parent node to download the dependent packages configured by this parent node, if some projects do not have to require this dependency package, this dependency package is declared as requiring no automatic download dependencies:Then the project that inherits this parent node is not automatically downloaded:If there is a project to configure this parent node t

generating the user interface, and is the only layer that the user can see in the entire MVC architecture, receiving user input and displaying the processing results; In the Android application, the description of the interface in the XML file is generally used, which can be easily introduced. Of course, you can use javascript+html and other ways as view.C (Controller control Layer) the responsibility of the Android control layer will fall on the sho

Data frames are divided into two categories: text and binary (for example, image data).Second, WebSocket life cycleThe first event of all Java WebSocket endpoint lifecycles is an open notification, which indicates that a connection to the other end of the WebSocket session has been

What activityis an interactive interface that fills the window or hovers over other windows, and an application consists of multiple activity, which specifies a master activity in the Mainifest.xml.When the program runs for the first time, it sees the main activity, which is related to the activity by initiating other activity.When other activity is started, the current activity will stop, new activity is pressed into the stack, colleagues get the

For iOS apps, it's important to know if your application is running in the foreground or in the background. Because system resources are limited on iOS devices, an application must behave differently in the background than in the foreground. The operating system also restricts your application from running in the background to improve battery

TypeA, but not that it is an instance of TypeA.Yes, it is a quote that we often say but often ignore. We all manipulate instances of a reference type by reference to the instance.So, there are three types of variables: Instances of value types Instances of reference types Reference But here's a very interesting question. As we all know, the spatial allocation of instances of reference types is on the heap. But how does the space for a in the example above be allocated? It

When a user enters. When you exit and enter your app again, your app Activity will switch between the various states of its life cycle.For example, when your activity starts for the first time. It takes the focus of the user in front of the system today. In this process, the Android system invokes a series of life cycle methods to set up the UI and other componen
