In Visual Studio, you can create a website in two ways: ASP. NET Web Site and ASP. NET Web Application. Compared with Web Site, Web Application has many advantages. There are already many articles on the Internet to illustrate their differences. An official blog on Visual Studio tells about their respective advantages

Verification control OverviewAs the name suggests, a verification control is a control that verifies the correctness of user input data. If a user enters data in the text box, a prompt is displayed, indicating that the verification data is invalid. The verification process can be executed on both the server and the client. The ver

PrefaceHTTP not only serves Web pages, but is also a powerful platform for building APIs that expose services and data. HTTP has a simple, flexible, and ubiquitous feature. You can think of. Almost all platforms contain an HTTP library, so HTTP services can be spread across a wide range of clients, including browsers, mobile devices, and traditional desktop applications.The ASP. NET Web API is a framework f

　 15. Adjust the number of threads for each auxiliary process of the application if necessary The request structure of ASP. net tries to strike a balance between the number of threads executing the request and the available resources. An application that uses sufficient CPU power is known. This structure determines the number of requests that can be executed simultaneously based on the CPU power available

WebControl class provides. You are familiar with some common attributes of the WebControl class, and then modify the attributes more deeply. I like to give things a full explanation slowly, or I feel uncomfortable, so I wrote it slowly, on the premise that I understand it. in this example, you can modify the code according to the second article. for errors, please indicate ^_^. RenderContents for ASP. NET

First, I want to explain: Asp. net built-in sitemap is completely different from the sitemap mentioned here, Asp. the sitemap in net is mainly used for user navigation, and the sitemap mentioned here is used to guide search engine crawlers. Let's take a look at the official explanation: What is sitemap? Sit

In ASP. NET project development, what are the issues with application exception handling? Let's start with our explanation: I believe you are familiar with the Application object and have added the Global. asax file to the project. Indeed, the codes for ASP. NET to handle exceptions at the application level are all sto

example, c: \ inetpub \ wwwroot \ Application name. The v parameter must be used with p, so the compiler can parse the root reference of any application. F: indicates whether the target directory is to be overwritten. U: used to set the pre-compiled application to be updated. This means that all the tag files (ASPX, ASCX, and so on) can be updated in the target directory. TargetDir: The target directory used to pre-compile the application file. The following command precompiled an application u

Page error handling ASP. NET provides two levels of global exception interception points, respectively at the page level and application level. A base-class page exposes an error event, which can be rewritten on the page to capture unprocessed exceptions caused during page execution. There is also an error event in the httpapplication class, which is used to

-entering the Web server.AppRequestQueueLimit: indicates the maximum number of requests that ASP. NET will queue for the application. Requests are queued when there are not enough free threads to process requests. When the queue exceeds the limit specified in this setting, the incoming request is rejected through the "503-the server is too busy" error message.EnableVersionHeader: Specifies whether

5. Page Lifecycle Now back to the content mentioned in the third title, we talked about the HttpApplication instance receiving requests and creating page class instances, in fact, this instance is an instance of the dynamically compiled ASPX class. In the previous title, we learned that ASPX is actually a subclass of the class in code binding, so it inherits all the protected methods. Now let's take a look at the CodeBehind class code automatically generated by VS.

IntroductionI have consulted many of the net books and found that most authors are standing on a higher level to explain the ASP. They are patient and meticulous in telling you how to drag and drop controls, set control properties, and write codebehind code to implement a specific function.This practice, in effect, answers the question of " how to do " , but does not answer the question " Why do you do thi

If you write code in ASP. NET, you need to use the following to ensure good performance: ◆ Do you want to use cache? ◆ Are you using session status? ◆ Is the application status you are using? ◆ Are you using the thread and synchronization functions? ◆ What is the effective management of your resources? ◆ Are you effectively managing strings? ◆ Can you effectively manage exceptions? ◆ Have you optimized your

asymmetric algorithms because one key is used to encrypt data and another key is used to decrypt data.. NET Framework provides the following classes to implement public key encryption algorithms:DSA: dsacryptoserviceproviderRSA: rsacryptoserviceprovider3. Hash ValueThe hash algorithm maps binary values of any length to smaller binary values of a fixed length. This smaller binary value is called a hash value. A hash value is a unique and extremely com

that it does not inherit any base class or implement any interfaces. From this we can see that Microsoft began to advocate the idea that "Conventions are better than Interfaces" in ASP. NET 5. We only need to implement a constructor that accepts RequestDelegate as the parameter, and an Invoke method with the same method signature as RequestDelegate. Of course, i

ASP. NET skills-data collection program introduction first let's look at some concepts, the so-called data collection program is also a Web page thief Program (Don't scold me ), after writing something, I hope you can study it together.

. TargetDir: The target directory used to pre-compile the application file. The following command precompiled an application using the virtual path and the specified target path: aspnet_compiler.exe-v/Application name c: \ target directory name. If no target directory is specified, the result file will be placed in the temporary file directory of ASP. NET, just like processing and compiling when
