ASP.NET 2.0 Features

2010-07-15T09:21:00.000+05:30

If you have worked with ASP.NET 1.x versions, you will undoubtedly agree that it was a great product
that provided huge improvements in the way web applications were designed and deployed. If
ASP.NET 1.x was a great product, then what’s wrong with it? Well, nothing, actually, but when developing
software, there is always a trade-off between how much can be done, how many resources you
have, and how much time you have to do it. There is an almost never-ending supply of features you
can add, but at some stage you have to ship the product. You cannot doubt that ASP.NET 1.0 shipped
with an impressive array of features, but the ASP.NET team members are ambitious, and they not only
had plans of their own but also listened to their users. ASP.NET 2.0 addresses the areas that both the
development team and users wanted to improve. The aims of the new version are:

❑ Reduce the number of lines of code required by 70%: The declarative programming
model freed developers from having to write reams of code, but there are still many scenarios
where this cannot be avoided. Data access is a great example, where the same
Connection, DataAdapter/DataSet, and Command/DataReader code is used regularly.
❑ Increase developer productivity: This partly relates to reducing the amount of code required,
but is also affected by more server controls encompassing complex functionality, as well as providing
better solutions for common web site scenarios (such as portals and personalized sites).
❑ Provide the fastest web server platform: Although ASP.NET 1.x offered a fast server platform,
ASP.NET 2.0 will improve areas such as application start-up times and provide better application
tracing and performance data. Innovative caching features will enhance application performance,
especially when SQL Server is used.
❑ Support for mobile development: In ASP.NET 1.0, the Microsoft Mobile Internet Toolkit (MMIT
in version 1.0 and ASP.NET Mobile Controls in version 1.1) provided this support, including
separate controls for building web pages suitable for small screen browsers. In ASP.NET 2.0, the
MMIT is no longer required because mobile support is built into all controls. This reduces the
amount of code required, as well as the need for specialist knowledge about mobile platforms.
❑ Provide the best hosting solution: With the large number of Internet applications being hosted,
it’s important to provide better solutions for hosters. For example, better management features
to identify and stop rogue applications will give hosters more control over their current environment.
More control can also be given to hosted companies by use of the new web-based
administration tool, allowing users to easily control the configuration of applications remotely.
❑ Provide easier and more sophisticated management features: Administration of ASP.NET applications
under version 1.x required manual editing of the XML configuration file, which is not a
great solution for administrators. Version 2.0 brings a graphical user interface–based administration
tool that is integrated with the Internet Information Services (IIS) administration tool.
❑ Easy implementation of entire scenarios: The better management features are built on top of a
management application programming interface (API), allowing custom administration programs
to be created. Along with application packaging, this will provide support for easily
deployable applications, with or without source.

First Asp Programe

2010-06-21T20:03:00.003+05:30

Now let us have our First ASP.NET program.
Let9s look at both the markup and the C# portions of a simple web forms application that generates a movie

line-up dynamically through software.
Markup Portion
Web form application part 1 -- SimpleWebForm.aspx
<% @Page Language="C#" Inherits="MoviePage" Src="SimpleWebForm.cs" %>

Supermegacineplexadrome!

Welcome to
Supermegacineplexadrome!

Showtimes for <%WriteDate();%>

<%WriteMovies();%>

And this is where the C# part of a web forms application comes in.
Web form application part 2 - SimpleWebForm.cs
using System;
using System.Web.UI;
using System.Web.UI.WebControls;
public class MoviePage:Page
{
protected void WriteDate()
{
Response.Write(DateTime.Now.ToString());
}
protected void WriteMovies()
{
Response.Write("The Glass Ghost (R) 1:05 pm, 3:25 pm, 7:00 pm
");
Response.Write("Untamed Harmony (PG-13) 12:50 pm, 3:25 pm, " +
"6:55 pm
");
Response.Write("Forever Nowhere (PG) 3:30 pm, 8:35 pm
");
Response.Write("Without Justice (R) 12:45 pm, 6:45 pm
");
}
}

Quick Start :To ASP.NET

File name extensions
Web applications written with ASP.NET will consist of many files with different file name extensions. The most common are listed here. Native ASP.NET files by default have the extension .aspx (which is, of course, an extension to .asp) or .ascx. Web Services normally have the extension .asmx.Your file names containing the business logic will depend on the language you use. So, for example, a C# file
would have the extension .aspx.cs. You already learned about the configuration file Web.Config.

Another one worth mentioning is the ASP.NET application file Global.asax - in the ASP world formerly known as Global.asa. But now there is also a code behind file Global.asax.vb, for example, if the file contains Visual Basic.NET code. Global.asax is an optional The easiest way to start The easiest way to start with ASP.NET is to take a simple ASP page and change the file name extension to .aspx.
Page Syntax
Here is quick introduction of syntax used in ASP.NET Directives
You can use directives to specify optional settings used by the page compiler when processing ASP.NET files. For each directive you can set different attributes. One example is the language directive at the beginning of a page
defining the default programming language.
Code Declaration Blocks
Code declaration blocks are lines of code enclosed in

Architecture of Asp

2010-06-20T12:51:00.000+05:30

ASP.NET is based on the fundamental architecture of .NET Framework. Visual studio provide a uniform way to combine the various features of this Architecture.
Architecture is explained form bottom to top in the following discussion.
At the bottom of the Architecture is Common Language Run time. NET Framework common language run time resides on top of the operating system services. The common language runtime loads and executes code that targets the runtime. This code is therefore called managed code. The runtime gives you, for example, the ability for cross-language integration.

1..NET Framework provides a rich set of class libraries. These include base classes, like networking and input/output classes, a data class library for data access, and classes for use by programming tools, such as debugging services. All of them are brought together by the Services Framework, which sits on top of the common Language runtime.
2.ADO.NET is Microsoft9s ActiveX Data Object (ADO) model for the .NET Framework. ADO.NET is not simply the migration of the popular ADO model to the managed environment but a completely new paradigm for data access and manipulation.ADO.NET is intended specifically for developing web applications. This is evident from its two major design principles:
Disconnected Datasets9In ADO.NET, almost all data manipulation is done outside the context of an open database connection.
1. Effortless Data Exchange with XML9Datasets can converse in the universal data format of the Web,namely XML.
2.The 4th layer of the framework consists of the Windows application model and, in parallel, the Web application model.
The Web application model-in the slide presented as ASP.NET-includes Web Forms and Web Services.
ASP.NET comes with built-in Web Forms controls, which are responsible for generating the user interface.
They mirror typical HTML widgets like text boxes or buttons. If these controls do not fit your needs, you are free to create your own user controls.
Web Services brings you a model to bind different applications over the Internet. This model is based on existing infrastructure and applications and is therefore standard-based, simple, and adaptable.
Web Services are software solutions delivered via Internet to any device. Today, that means Web browsers on computers, for the most part, but the device-agnostic design of .NET will eliminate this limitation.
4.One of the obvious themes of .NET is unification and interoperability between various programming languages. In order to achieve this; certain rules must be laid and all the languages must follow these rules. In other words we can not have languages running around creating their own extensions and their own fancy new data types. CLS is the collection of the rules and constraints that every language (that seeks to achieve .NET compatibility) must follow.
5.The CLR and the .NET Frameworks in general, however, are designed in such a way that code written in one language can not only seamlessly be used by another language. Hence ASP.NET can be programmed in any of the .NET compatible language whether it is VB.NET, C#, Managed C++ or JScript.NET.

Intoduction to Asp.Net

2010-06-18T09:20:00.001+05:30

I have seen many tutorials on ASP.NET but most of them starts with coding and writing your first ASP.NET Program. But here I has written this tutorial for explaining why there is a need for ASP.NET when classy ASP is working fine and what are the underlying technology behind ASP.NET, What programming model ASP.NET

Provides to programmers. Now let us get started.ASP.NET is the new offering for Web developers from the Microsoft .It is not simply the next-generation of ASP;

in fact, it is a completely re-engineered and enhanced technology that offers much, much more than traditional.ASP and can increase productivity significantly.

Because it has evolved from ASP, ASP.NET looks very similar to its predecessor9but only at first sight. Some items look very familiar, and they remind us of ASP. But concepts like Web Forms, Web Services, or Server Controls gives ASP.NET the power to build real Web applications.

Advantage of Asp.Net

Support for compiled languages

developer can use VB.NET and access features such as strong typing and object-oriented programming.

Using compiled languages also means that ASP.NET pages do not suffer the performance penalties

associated with interpreted code. ASP.NET pages are precompiled to byte-code and Just In Time (JIT)

compiled when first requested. Subsequent requests are directed to the fully compiled code, which is

cached until the source changes.

Use services provided by the .NET Framework

The .NET Framework provides class libraries that can be used by your application. Some of the key classes

help you with input/output, access to operating system services, data access, or even debugging. We will

go into more detail on some of them in this module.

Graphical Development Environment

Visual Studio .NET provides a very rich development environment for Web

developers. You can drag and drop controls and set properties the way you do in Visual Basic 6. And you

have full IntelliSense support, not only for your code, but also for HTML and XML.

State management

To refer to the problems mentioned before, ASP.NET provides solutions for session and application state

management. State information can, for example, be kept in memory or stored in a database. It can be

shared across Web farms, and state information can be recovered, even if the server fails or the connection

breaks down.

Update files while the server is running!

Components of your application can be updated while the server is online and clients are connected. The

Framework will use the new files as soon as they are copied to the application. Removed or old files that

are still in use are kept in memory until the clients have finished.

XML-Based Configuration Files

Configuration settings in ASP.NET are stored in XML files that you can easily read and edit. You can also

easily copy these to another server, along with the other files that comprise your application.
