Asp. NET Beida Jade Bird--Summary article

System of ASP, in fact, really do not have many things, read the whole Peking University bird's video, I think things in summary and constant contrast will be changed by less, there is less change.

(i) from the concept summary content

Concept: The main function of ASP is to combine scripting language, HTML, Component (Control) and Web database access to form an application that can be performed on the server side.

Summary: ASP can be divided into 4 parts: scripting language, HTML, controls, and Web database access capabilities. We summarize from four aspects, in fact, in the early two we have not only contact, and very skilled, we have done the computer room fee system is to use Windows Form and Web database access to achieve big data access. For the first two, HTML we also have access to the Beef Brisket press release system.

Of course, this map is based on my understanding of the drawing, but also with other links related to the four-part relationship, are not related.

(b) The principle of ASP operation:

In fact, it is very simple that the client (browser) sends the server side through the HTTP request, the server side responds to the client.

Don't think too much about the problem here, and it will deepen your understanding later.

(iii) server-side interaction with the client

In fact, it is built on several objects of the ASP. ASP. NET object for request object and Response object, of course, there are other, but these two are the most commonly used, specifically what role, you can see the bottom of the detail (3).

(iii) in-depth understanding of the content and relationship of Part four

We start with the scripting language, scripting language is written in HTML (of course, personally think can be written in the JS file), the scripting language as part of the HTML, scripting language has two kinds: VBScript and JavaScript, the other can not be ASP. NET use. HTML files are object-oriented, so Web controls are also part of it, as objects are used, because Web controls have the properties of objects: properties and methods that respond appropriately to events.

The HTML control begins with input, and the ASP interior space is the beginning of the ASP, plus the runat= "server" to become an HTML control, using roughly the same usage.

Asp. NET control is divided into four parts, on the graph, I won't say, the video is a large part of the time is the introduction of these controls, and in fact, they are similar, can be said that extrapolate will also use, such as: List control and validation controls and internal controls.

Asp. NET also has objects similar to global variables, that is, the application, server, Session object in.

The rest is the Web database access functionality, which we have learned, and very skilled, is the database access to the object, connect the database, manipulate and control the database, and so on, the only difference here is, ADO. NET database when the connection is disconnected.

Here is a detailed picture:

(iv) Summary

1, in the study of this part, we have to learn from the previous study of things to contact and merge, so you will find a large part of us have been exposed, it will deepen our understanding.

2, according to their own understanding of the classification of knowledge, the difference.

3, grasp the key summary, macro-clear what I learn, not to seek the overall is not.
