ASP Consolidation Listview Vb.NET logo
ASP Listview Vb.NET Consolidation is a web application framework marketed by Microsoft that programmers can use to build dynamic websites, Web applications and XML Web services Consolidation Listview Vb. It is part of Microsoft 's Consolidation Listview Vb.NET platform and is the successor to Microsoft' s Active Server Pages (ASP) technology Coding Listview Vb. ASP Coding Listview Vb.NET is based on the Common Language Runtime, which allows programmers to write ASP Coding Listview Vb.NET Microsoft code using any language encoding Listview Vb.NET Consolidation Listview Vb.

Characteristics

ASPX format FILE
ASPX Html is a file format used to create pages Webform in programming jargon, the ASPX file typically contains HTML or XHTML trademark, as well as the definition of Web brands Controls Web user controls and place where developers all dynamic content and the website Coding Listview Vb. In addition, the dynamic code that runs on the server can be placed on a page within a block &llt;% - dynamic code -% &ggt; which is similar to other Web development technologies such as PHP, JSP and ASP, but this practice is generally frowned upon by Microsoft, except for the purpose of binding data because it requires making more calls when the page Codification Listview Vb.
It is recommended Microsoft to cope with dynamic program code to use the code - Behind model, which placed this code in a separate file or in a script specially designated label Consolidation Listview Vb. Code-behind files usually named something to the effect Consolidation Listview Vb.aspx MyPage Listview Vb.cs or Coding Coding MyPage Listview Vb.aspx Consolidation Listview Vb.vb ASPX based on the file name (this Practice is automatically in Microsoft Visual Studio and other IDEs) Consolidation Listview Vb. When using this style of programming, the programmer writes code to respond to different events, like the page is loading, or a control is clicked, instead of a stroll through the paper Consolidation Listview Vb .

Rendering technical
"Consolidation ASP Listview Vb.NET" uses a technique of rendering visited compounds Consolidation Listview Vb. During the compilation of the template (Consolidation Listview Vb.aspx) file is compiled in initialization code that will build a tree control (composite), representing the original (static) Coding template Listview Vb. Text is literally in the case of the literal control of the class, server controls are represented by instances of a particular kind of control Coding Listview Vb. The initialization code is combined with user-written code (usually by assembling various kinds partial) and results in a specific class of the page Consolidation Listview Vb. The site serves as the root of the tree control Consolidation Listview Vb.
Actual requests for the page are processed through a series of steps Codification Listview Vb. First, during initialization of the steps, a body of the page is created and the class initialization code runs Consolidation Listview Vb. This produces the initial control tree that is normally handled by the methods of the page in the following stages of coding Listview Vb. As each node in the tree control is represented as an instance of a class, the code can change the structure of tree, as well as manipulate the properties or methods from each of the nodes Consolidation Listview Vb. Lastly, the provision for the passage of a visitor used to visit each node in the tree, asking each node to cast itself, using methods Coding visitors Listview Vb. The resulting HTML code is sent to the client Consolidation Listview Vb.
After the application has been processed, the instance of the class is thrown page and with it control of the entire tree coding Listview Vb.

Other files
Other file extensions associated with different versions of ASP Coding Listview Vb.NET include:

Global Consolidation Listview Vb.asax, used for application-level logic

Web UserControls: Custom Controls to be placed on the websites of Consolidation Listview Vb.

custom HTTP handlers Consolidation Listview Vb.

service websites Codification Listview Vb.

when enabled on the web Consolidation Listview Vb.config asking crawl Listview Vb.axd products encoding application-level tracing Consolidation Listview Vb. It is also used for webresource axd handler special permits control, component developers to a component of packages / complete with pictures, writing, CSS, etc. Consolidation Listview Vb. For its deployment in a single file (an "assembly")

browser capabilities of the files stored in XML format, introduced in the version 3 Codification Listview Vb.0 Consolidation Listview Vb. ASP Coding Listview Vb.NET 2 includes many of them by default, support for web browsers Codification Listview Vb. These browsers have to specify that the skills, so that ASP Coding Listview Vb.NET 2 can automatically customize and optimize their production accordingly Consolidation Listview Vb. Special Consolidation Listview Vb.browser files are available for download free to operate, for example, the W3C Validator, so correctly display the pages compatible with the standards to be compatible with standard coding Listview Vb. Replacing the harder to use BrowserCaps section that was in the machine coding Listview Vb.config and can be annulled on the Web Coding Listview Vb.config in ASP Coding Listview Vb.NET 1 Codification Listview Vb.x Consolidation Listview Vb .

Web Coding Listview Vb.config is the only file in a Web application to use this extension by default (machine Coding Listview Vb.config similar affects the entire Web server and all applications therein), however ASP Coding Listview Vb.NET provides facilities to create and consume other configuration files encoding Listview Vb. These are stored in XML format, in order to allow configuration changes to be made with the simplicity of Consolidation Listview Vb.

ASP Coding Listview any Vb.NET 2 cs / vb files placed inside the folder App_Code are dynamically compiled and available for the entire application coding Listview Vb.

Master Pages; introduced in version 2 Codification Listview Vb.0

site map configuration files

theme of the skin Encoding Listview files Vb.

resource files for the internationalization and localization of Consolidation Listview Vb. Archives of resources can be global (and Listview Vb.g Consolidation Consolidation Listview Vb. Messaging) or "local", which means specific to a single file or aspx or ascx Codification Listview Vb.

(version 3 Codification Listview Vb.5) LINQ classes of data files SQL

Directory structure
In Overall, the ASP Coding Listview Vb.NET directory structure can be determined by the promoter 's encoding preferences Listview Vb. Apart from some directory names aside, the site can span any number of directories Consolidation Listview Vb. The structure is typically reflected directly in the URL Encoding Listview Vb. Although ASP Coding Listview Vb.NET provides means to intercept the request, at any point during the process, the developer is not forced through a funnel requests for central application or front driver Consolidation Listview Vb.
The special names directory are:

has site-specific browser definition files Coding Listview Vb.

This is the "raw code" Directory Consolidation Listview Vb. The ASP Coding Listview Vb.NET server automatically compile the files (and subdirectories) in this folder where an assembly is accessible in the code of each page of the site coding Listview Vb. App_Code normally used to access data abstraction code, the code and the business model code encoding Listview Vb. Also any specific site http handlers and service modules and web application go Consolidation of this directory Listview Vb. As an alternative to using App_Code developer may choose to offer an assembly with the code prebuilt Codification Listview Vb.

default directory for databases such as Access mdb files and SQL Server files mdf Consolidation Listview Vb. This directory is often the only write access to the application coding Listview Vb.

contains localized resource files for different pages on the site coding Listview Vb. E Listview Vb.g Consolidation Consolidation Listview Vb. CheckOut a file called Coding Listview Vb.aspx Consolidation Listview Vb.fr-FR Consolidation Listview Vb.resx has localized resources for the French version of the Coding CheckOut Listview Vb.aspx page Consolidation Listview Vb . When the culture of the user interface is defined in French, ASP Coding Listview Vb.NET automatically find and use this file to the location of Consolidation Listview Vb.

It resx localized files with the resources available to each page of the site Coding Listview Vb. This is where the ASP Coding Listview Vb.NET store developer typically localized messages etc. Consolidation Listview Vb. To be used in more than one page Codification Listview Vb.

Have alternative themes of the Coding site Listview Vb.

discovery has WSDL files and references to files web services that are consumed on the site coding Listview Vb.

Performance
ASP Consolidation Listview Vb. NET intends to maintain performance benefits over others based scripting technologies (including Classic ASP) for compiling the server side code to one or more DLL files on the web server Codification Listview Vb. Compilation This happens automatically the first time a page is requested (Which means that the developer does not have to make a compilation step of the pages) Consolidation Listview Vb. This feature provides the ease of development offered scripting languages with the performance benefits of a binary encoding Listview Vb. However, the compilation could cause a noticeable delay when a Web user newly edited page called for the first time since the web server Coding ASPX Vb.
The Listview and other resource files are placed in a virtual machine on an Internet Information Services (or other compatible ASP Coding Listview Vb.NET servers; Other implementations see below) Coding Listview Vb. The first time a client requests a page, Coding Listview Vb.NET framework compiles and analyzes the file (s) in a Coding Listview Vb.NET reunion and sends the answer; subsequent requests are Serves of the DLL files Codification Listview Vb. By default ASP Coding Listview Vb.NET compile entire site in batches of 1,000 files on his first application Codification Listview Vb. Compilation If the delay is causing problems, the size of the lot or the compilation strategy can be adjusted Codification Listview Vb.
Developers also eligible for the validity of compiling the code prior to deployment, eliminating the need for "just in time compilation in a production environment Codification Listview Vb.

Extension
Microsoft has released some frameworks extension plug in making ASP Coding Listview Vb.NET and expand its functionality encoding Listview Vb. Some of them are: ASP

An extension to both by the client and the server-side components to write ASP Coding Listview Vb.NET pages that incorporate the functionality of AJAX coding Listview Vb.

An extension to author Coding Listview Vb.NET ASP pages using the MVC architecture Consolidation Listview Vb.

ASP Coding Listview Vb.NET compared with classic ASP
ASP Consolidation Listview Vb.NET attempts to simplify developers' transition from Windows to the development of Web applications development by offering the ability to create pages controls compound similar to a Windows user interface Consolidation Listview Vb. A web control, such as a button or tag, functions in much the same way as its counterpart in Windows code may assign their properties and respond to events Consolidation its Listview Vb. Controls know how to do for themselves: while Windows controls bring to the screen, controls web produce segments of HTML and JavaScript which are part of the resulting page sent to the end user 's browser Consolidation Listview Consolidation Vb.
ASP Listview Vb.NET encourages programmers to develop applications using an event-driven paradigm of the GUI (graphical user interface event-driven model), rather than conventional on the Web, such as ASP and scripting environments PHP Coding Listview Vb. The framework of attempts to combine existing technologies, such as JavaScript with internal components as "ViewState" to persistent (inter-application) for the state intrinsically stateless web environment Consolidation Listview Vb.
Other differences compared with classic ASP are :

• Compiled code applications run faster means more errors in design time trapped in the development phase encoding Listview Vb.
• Significantly improving runtime error handling, using the exception Handling try using catch blocks Consolidation Listview Vb.
• Similar metaphors to Windows applications, such as checks and events that make the development of rich user interfaces, previously only found on the desktop, the possibility Coding of Listview Vb.
• An comprehensive set of class libraries and controls allows rapid construction of applications and controls allow user-defined templates for common use, such as menus Consolidation Listview Vb. Disposal of these controls on a page is easier because most of what can be done visually, in the majority of editors Consolidation Listview Vb.
• ASP Consolidation Listview Vb.NET leverages the capabilities of the multi-language Encoding Goods Listview Vb.NET CLR, which allows Web pages to be coded in VB Consolidation Listview Vb. NET, C #, J #, etc. Consolidation Listview Vb.
• Ability cache to the whole page or part of it to improve the performance of Consolidation Listview Vb.
• Ability to use the code behind development model to separate the logic business presentation Codification Listview Vb.
• If ASP Coding Listview Vb.NET application memory leaks, the ASP Coding Listview Vb.NET runtime download the AppDomain host the offending application and re-load the application in a new AppDomain Consolidation Listview Vb.
• Session state in ASP Coding Listview Vb. NET can be saved in a SQL Server database or in a separate process running on the same machine as the Web server or on a different computer Codification Listview Vb. Sitting this way values are not lost when the web server is restarted or ASP Coding Listview Vb.NET worker is recycled process Coding Listview Vb.
• Previous versions of ASP Listview Vb.NET Coding (1 Consolidation Listview Vb.0 and 1 Codification Listview Vb.1) were criticized for their lack of compliance with the rules of Coding Listview Vb. The generated HTML and JavaScript sent the client browser is not always validate against W3C/ECMA encoding standards Listview Vb. Furthermore, within the framework "s browser detection feature sometimes incorrectly identified web browsers other than Microsoft 's Internet Explorer itself as a" downlevel "and returned HTML / JavaScript to these customers with some of the features, or sometimes mutilated Consolidation or broken Listview Vb. However, in version 2 Codification Listview Vb.0 generate all controls coding HTML 4 valid Listview Vb.0, XHTML 1 Codification Listview Vb, 0 (default) or XHTML 1 Codification of Listview Vb.1 exit, depending on the configuration of the site coding Listview Vb. Detection compatible with the standard web browsers is more robust and support for Cascading Style Sheets is broader Coding Listview Vb.
• Web server controls: These are controls introduced by ASP Coding Listview Vb.net to provide the user interface for Web form Coding Listview Vb. These controls are managed state controls and WYSIWYG (What you see is what you get) controls coding Listview Vb.

Criticisms ASP Coding Listview Vb.NET
Several controls, the controls Start Session and the Wizard control, use HTML to design tables encoding default Listview Vb. Microsoft has gone some way to resolve this problem by releasing Consolidation of the ASP Listview Vb.NET 2 Coding Listview Vb.0 CSS Adaptors Control, a free add-producing accessible and compatible with XHTML + CSS Coding Trademark Listview Vb. However, some still rely on checks coding JavaScript Listview Vb.
The ASP Coding Listview Vb.NET ViewState is based on the encoding mechanism called PostBack Listview Vb. Desirable Although, in general, to fill out forms in this poses a problem with some controls when used in a mere "road" scenario Consolidation Listview Vb. One example is the DataGrid that when using the ability to support a set of speakers for the state of using postback Consolidation Listview Vb. Because the state is not externalized in the URI, this means that search engines will find it difficult to index all the "pages" Codification Listview Vb. The engine will have to emulate the postback - normally not Consolidation Listview Vb.

Development tools exist
Several software packages available for the development of ASP Coding Listview Vb.NET applications:

• Microsoft its network, part of the Microsoft Expression Studio suite of applications coding Listview Vb.
• Visual Studio Listview Vb.NET Coding (for ASP Coding Listview Vb.NET 1 Codification Listview Vb.x)

• Visual Web Developer 2005 Express Edition or Visual Studio 2005 (for ASP Coding Listview Vb.NET 2 Encoding Goods Listview Vb.0)
• Visual Studio 2008 or Visual Web Developer 2008 Express Edition (for ASP Coding Listview Vb.NET 3 Coding Listview Vb.5)
• Macromedia Dreamweaver MX, Macromedia Dreamweaver MX 2004, Macromedia Dreamweaver 8 (not arrive t support ASP Coding Listview Vb.NET 2 Coding Listview Vb.0 characteristics, and produces very inefficient code ASP Coding Listview Vb.NET 1 Codification Listview Vb.x: Also, the code generation ASP and Encoding Goods Listview Vb.NET features support through version 8 Codification Listview Vb.0 Consolidation Listview Vb.1 was little or no change from version MX: Version 8 Codification Listview Vb.0 Consolidation Listview Vb.2 be added changes to improve security against attacks by SQL injection)

• Microsoft SharePoint Designer 12
• Delphi 2006
• MonoDevelop (Free / Open Source)
• SharpDevelop (Free / Open Source)

Frameworks
It is not essential for the use of web forms standard in the development of model development ASP Coding Listview Vb.NET Consolidation Listview Vb. Identify frameworks designed for the platform include:

• Castle Monorail, an open-source MVC framework for the execution of a model similar to Ruby on Rails Consolidation Listview Vb. The framework is commonly used with ActiveRecord Castle, built on a layer ORM NHibernate Consolidation Listview Vb.
• Spring Consolidation Listview Vb.NET, a port in the spring of framework for Coding Java Listview Vb.
