://kerry.com? Lover = notus. The so-called ASP. NET url rewriting is in this step. Use. in terms of net, we need to register an httpmodule for the application to process specific URLs and register the httpmodule. config, processing the url. In the httpmodule program we provide, it is roughly equivalent to such a process. // Use our httpmodule program to

Getting Started: ASP. net mvc Routing As a developer who transfers data from ASP. NET to ASP. net mvc, you may have started using routes when developing ASP.

defines the signature used to write an event handler. When an item is removed from the cache, this event handler is called. ASP. NET also provides cacheitemremovedreason enumeration to specify the reason for removing cache items. Generally, callback is implemented by creating a processing program in the business object that manages the specific cache data to b

code field: ControlToValidate="ZipCodeTextBox" ErrorMessage="Invalid ZIP code format; format should be either 12345 or 12345-6789." ValidationExpression="(\d{5}(-\d{4})?" /> UseRegularExpressionValidatorPay attention to the following issues: Never use an empty string in the control to be verified by the validators. Only RequiredFieldValidator can capture null strings. You do not need to specify the start and end of the matching character (^And$)-

fully object-oriented mode, allowing you to capture events. In addition, user controls allow you to write ASP in one language. NET page, and use another language to write ASP. NET page, because each user control can be written in a different language than the home page.

Update the reference to the following Assembly to point it to the new Preview 4 assembly: System. Web. Category actions System. Web. Routing

Basic part of ASP. NET interview questions 1. What is packing and unpacking? 2. What is overload? 3. What is the difference between the value type and the reference type? 4. How to understand delegation? 5. UnderstandProgramIs the set strong signature? 6. What is the difference between C # interfaces and classes? 7. Please explain the technical t

Although in ASP. net mvc 1 does not support asynchronous actions directly, but in ASP. net mvc 2 has officially supported ASP.. NET, and is provided to developers in a relatively easy-to-use way. It is a pity that due to language

affected and will still be executed after the call is successful. The onfailed callback function accepts a parameter of the type SYS. net. webserviceerror, indicating the exception object. The function signature is similar to the following: Function onfailed (error ){ // Obtain and handle exception information } The sys. net. webserviceerror type of

each developer will spend hours in some cases addressing bugs that are caused by this feature. Objects are language-level variables in PHP. They are largely treated as simple variable types. (Just like an integer and a character variable) the entire object is copied when an operation such as a variable assignment and an object is passed as a parameter to a function. This will lead to inefficiency. In addition, unpredictable run-time behavior can occur frequently. PHP lacks some of the key elem

think that the website is faulty and the user cannot think that he has entered invalid characters! What should we do in this case? Fortunately, Microsoft engineers gave another Page_Error event in the page, so that we can use it to capture exceptions. The Code is as follows: Protected void Page_Error (object sender, EventArgs e) { ExceptionEx=Server. GetLastError (); If (ex is HttpRequestValidationException) { Response. Write ("the cha

ASP. NET has made several improvements in handling and responding to errors. In traditional ASP, "On Error resume next" (or try-Catch Block in JScript) is used to handle errors. Alternatively, if you are running Microsoft Internet Information Services (IIS) 5.0, use the asperror object to create a custom error report page. However, these methods have their own li

ASP. NET applications can use exception capture in code to handle errors (try and catch). However, exception capture is a bad programming habit. Try and catch are easy to use, but excessive use may cause serious performance loss. If exceptions can be detected, try to use other methods, and use exception

the application when items are removed from the cache. For example, a report with a cache may take a lot of time to process. When the report is removed from the cache, you do not have to wait for the report to be processed the next time you request the report. ASP. NET provides CacheItemRemovedCallback delegation, which can send notifications when items are removed from the cache. The CacheItemRemovedReaso

If you want to redirect to a specific error page that has to know the exact URL or configure it to co-exist with Customerr ORS or HttpErrors.Use caseIn terms of generic error logging The is a great place to start with! It'll capture all errors which haven ' t been handled on an earlier stage. But was careful, if you had used controller exception handling and set

inetpubwwwroot application. 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 using the virtual path an

ASP. NET pen questions will examine all aspects of programmers, so what kind of questions will arise during the interview? 1. in C #, use text or images to describe the differences between string str = null and string str =. String str = null indicates that no memory space is allocated to him, while string str = "" assigns it a memory space with a length of null characters. 2. Describe the similarities and
