What is ASP.NET?
ASP.NET is a server side scripting technology that enables scripts (embedded in web pages) to be executed by an Internet server.
* ASP.NET is a Microsoft Technology
* ASP stands for Active Server Pages
* ASP.NET is a program that runs inside IIS
* IIS (Internet Information Services) is Microsoft's Internet server
* IIS comes as a free component with Windows servers
* IIS is also a part of Windows 2000 and XP Professional
ASP.NET is a web application framework developed and marketed by Microsoft to allow programmers to build dynamic web sites, web applications and web services. It was first released in January 2002 with version 1.0 of the .NET Framework, and is the successor to Microsoft's Active Server Pages (ASP) technology. ASP.NET is built on the Common Language Runtime (CLR), allowing programmers to write ASP.NET code using any supported .NET language. The ASP.NET SOAP extension framework allows ASP.NET components to process SOAP messages.
ASP.NET has emerged as an answer to the problems that the developers used to face with the classic ASP. Since ASP has an extensive use, however, Microsoft ensured that ASP scripts perform without modification on a machine with the .NET Framework (the ASP engine, ASP.DLL, is not customized when installing the .NET Framework). Thus, IIS can accommodate both ASP and ASP.NET scripts on the same machine.
Advantages of ASP.NET
1.Division of Code from HTML:
To make a clean sweep, with ASP.NET you have the capability to completely detach layout and business logic. This makes it much simple for the programmers and designers to collaborate efficiently. There is also a high level of efficiency achieved through this.
2.Support for compiled languages:
The developer can use VB.NET and access those vital things like strong typing and object-oriented programming. Using compiled languages signifies that ASP.NET pages do not have the similar performance penalties which are all linked with interpreted code. ASP.NET pages are precompiled to byte-code and Just In Time (JIT) compiled when it is requested. All the requests henceforth made are directed to the fully compiled code, which is cached until the source changes.
3.Use services provided by the .NET Framework:
The .NET Framework offers class libraries that are usable by your application. Some of the chief classes help you with input/output, access to operating system services, data access, or even debugging.
4. Graphical Development Environment:
Visual Studio .NET offers a potential development environment for Web developers. It is feasible to drag and drop controls and set properties the way you do in Visual Basic 6. There is a full IntelliSense support, not only for your code, but also for HTML and XML.
5. State Management:
In answer to the problems which developers faced ASP.NET provides solutions for session and application state management. State information can, can be confined in memory or stored in a database. It is also sharable across Web farms, and state information can be recovered, in case the server fails or the connection breaks down.
6. Update files while the server is running!
You can update the components of your application while the server is online and clients are connected. The Framework will use the new files
at the same moment that they are copied to the application. The files which have become old and needs to be removed are still in use are kept in memory until the clients have completed.
7. XML-Based Configuration Files:
Configuration settings in ASP.NET can be kept in XML files that are easily readable and can be edited. It is also easy to copy these to another server, along with the other files that include your application.

ROR Open Source Web Application Framework
Ruby on Rails is an open source web application framework coded in Ruby that follows the Model View Controller (MVC) architecture. Ruby is an object oriented scripting language. Rails is a Model-View-Controller (MVC) framework based on Ruby and used for developing web applications. The Rails framework supports MySQL, PostgreSQL, SQL Server, DB2 and Oracle databases.
Ruby on Rails is separated into various packages, namely ActiveRecord (an object-relational mapping system for database access), ActiveResource (provides web services), ActionPack, ActiveSupport and ActionMailer. Prior to version 2.0, Rails also included the Action Web Service package that is now replaced by Active Resource. Apart from standard packages, developers can make plugins to extend existing packages.
A content management system provides the foundation for an easy to maintain a website. A key factor in deciding which CMS to use should be the customization factor. When I say customization factor, I mean the how difficult it is to develop custom functionality particular to your project. Some CMS systems make this easy while others present more of a challenge.
A minor phenomenon has swept the Web world in the last few years. Like many things in the realm of software, it was over hyped. I'm talking about the open-source Web development framework called Ruby on Rails. The RoR market is more than ready for anything that gives them visibility into their applications, whether that is on the developer's desktop or the running production application.
Ruby on Rails, also known as RoR, is an open source web programming application framework meant for faster web applications. The Ruby programming is a free program and is constantly improved by Ruby on Rails Programmers to make it more better and user friendly. Ruby on Rails development comes with features such as Model View Controller architecture that separates data from logic i.e. presentation layer and helps in organizing application program. RoR database access library simplifies data handling. Rails framework has an extensive AJAX library which it uses to generate AJAX code and the required Java script is automatically generated.
Benefits of Ruby on Rails include:
1. Rails works well with various web servers and databases as it is really easy to deploy web solutions using Rails.
2. With Ruby on Rails work is done faster otherwise before web applications which were using languages such as PHP, Java, ASP, could take ages to complete and in the end you may just have a large stack of unmentionable codes.
3. Rails provide fast and easy development with quality results.
4. With Ruby programming language you need to write few lines of code in comparison to other programming language to reach the same result.
5. The Ruby on rails framework software also supports MySQL, SQL, SQL Server, DB2 and Oracle.
6. ROR CMS provides very flexible solutions, final output depends on user choice no pre-format is mandatory, image cropping, resizing, multi-language support, excellent usability, sort able tree-based admin interface, layout editor, scaffold template is created.
7. Rails applications are Tailor made to perfection for an individual or an enterprise and best fit for all kind of web application. Rails architecture is used and most preferred for development of cms, e-commerce, portals, collaboration, and community.
The new performance management and profiling tools are important additions to the RoR development community as RoR moves from being a hobbyist development language to a bona fide enterprise development framework. Most of our attention now is moving over to the general rails environment and ecosystem creating tools and environments for development and production so that people can work better with and on their rails applications.

Flex Application - Powerful Tool For Developing
Have you planed to make rich and interactive application? It is little bit difficult for developing good and interactive applications. Flex makes it easy and fast to build applications. This is especially due to the many standard components. Much can be modified in Flex, such as colors and properties such as shadows and corners. The most common approach building software appliances, is to build it with the standard components and skin it later on. This not only affects the design, but also does not involve the end user in the process. Flex is a powerful tool for developing rich internet applications but for beginners, Flex may be a bit overwhelming. Perhaps you understand the basics of Flex and what it can do for you, namely some of the beneficial features like cross compatibility, but you lack a concrete understanding of the ins-and-outs of the platform. This article will suggest some methods for familiarizing yourself with Flex as well as methods for laying out applications, making code changes, repeating components, and managing data.
Sample Applications are Great Learning Tools
Unless you're an expert, you might find it beneficial to do some practice with Flex before you start developing applications. There are a number of sample applications that you can manipulate in order to familiarize yourself with Flex and exactly what it can do. Flex can be utilized to create simple applications that feature the basic building blocks of application development, but also gives developers the power to create complex, interactive applications. Many of the major features in flex can be surveyed using Flex Explorer. Quickly learn about these major features as well as the kind of control that Flex gives to developers.
Using Containers and Controls to Lay out Applications
In simpler terms, containers are the components of a user interface that allow you to control the layout of your application. Child sizing, positioning, and navigation are examples of features that are controlled by containers. Buttons, Text Area, and Combo Boxes are examples of controls that are components of the user interface. MXML tags are used to bring containers and controls to your application but developers can also use ActionScript to add them at runtime.
Enhancing Performance with Code Changes
There are a number of facts that developers should consider when creating their applications. The smooth operation of applications is vital to their success and as such understanding code changes can be crucial for enhancing performance. For example, start up times for applications are slowed drastically when you have too many levels of nested containers. Similarly, applications can be slowed by Macromedia Flash Debut Player and by the use of trace statements. Slowed performance is a considerable annoyance to the end user and as such you should always be sure to test your application in both Flash Player and Flash Debug Player to ensure smooth running.
A container’s creation policy property can help you determine when you should create components at runtime. Applications can create components at various stages: at start up, when users navigate to a container, or even because of user interaction. Therefore, you should configure an application so that it is laid out incrementally at start up. Likewise, the position, width, and height of components are customizable so that start up time can be enhanced. Moreover, performance can be improved with the Grid container but only when controls are required to line up horizontally and vertically. As you can see, the developer has a number of tools and resources to improve performance at every stage of the development process.
Repeating Components
Developers are always looking for the best way to dynamically repeat components. In Flex, you have a choice between the Repeater object, Horizontal List, Tile List, or List control. Better performance can be achieved by replacing layouts as is appropriate. For example, during the Flex 1.0 timeframe, you can replace layouts created using Repeater with a combination of a Horizontal List or Tile List and a cell renderer.
If you want to repeat a small number of simple user interface components, you can use the Repeater object. Examples of this layout include Radio Button controls or other controls that are used in Form containers. On the other hand, if you want to display more than a few repeated objects, you can use the Horizontal List, Tile List or List control.
To display data horizontally, much like an HBox container, you can use the Horizontal List. Items are always displayed from left to right when using the Horizontal List while the Tile List displays items in a tile layout, as you would expect from the Tile container. Therefore, Tile List provides the direction property that decides whether the next item is down or to the right. The List displays items in a single column and all these controls, Horizontal List, Tile List, and List, instantiate all objects that can be seen in the list.
Data Management
Finally, Flex provides a number of resources and tools for managing data. Using MXML tags you have a number of options for data management. You can send data to server-side data sources using HTTP Post and GET commands, Java objects or other web services. You can also receive data from these server-side data sources and even share data between client-side items in your application. Furthermore, data can easily be stored in client-side objects. Moreover, data can be manipulated before it is used or displayed; for example, you can format data before it is displayed in the user interface and you can validate your data before it is used as well.
As one of the most versatile developer platforms, Flex has quite the reputation to live up to. Developers choose Flex because of the range of control they experience and also because of the design and style elements of Flex. Whether you’re looking to build a very simple application or you want to create a uniquely rich internet application that features all the bells and whistles of modern RIA, Flex gives you the tools you need.

Open Source - Php Application Development
Open source describes practices in production and development that promote access to the end product's source materials. Some consider open source a philosophy, others consider it a pragmatic methodology. Before the term open source became widely adopted, developers and producers used a variety of phrases to describe the concept; open source gained hold with the rise of the Internet, and the attendant need for massive retooling of the computing source code. Opening the source code enabled a self-enhancing diversity of production models, communication paths, and interactive communities. Subsequently, a new, three-word phrase "open source software" was born to describe the environment that the new copyright, licensing, domain, and consumer issues created.
PHP is a powerful tool for making dynamic and interactive Web pages. PHP is open source, meaning that everyone has free access to the source code and can use it for own development purposes. PHP provides high compatibility with leading operating systems and web servers such as thereby enabling it to be easily deployed across several different platforms. PHP extensions include support for features such as XML parsing, compression utilities, dynamic generation of images, translation functions etc.
Here are some advantages why use PHP?
* Easy integration
* Flexibility
* Free Open Source
* PHP l run on any platform
* PHP is extendible
* Better performance and reliability

The Security of PHP and MySql
This article provides a basis for understanding secure programming with PHP and gives a broader view of the subject. You should keep in mind that these guidelines identify only the most common threats and how to avoid them, reducing the risk of security compromise at the same time. The basic rule for writing a secure application is: never trust user input. Poorly validated user input constitutes the most severe security vulnerabilities in any web application. In other words, input data should be considered guilty unless proven innocent. Choosing php and mysql as programming language for a website is not enough. With open source coding being one of the inherent properties of php mysql development, securing your codes becomes essential. So when one allows the users to upload files on the website, then security is definitely at stake.
PHP Programming Protection
While it is not entirely possible to protect your site, yet there are few precautions that you can incorporate for better protection of PHP programming. Some of these are:
• You should check the referrer, for being sure that the information sent is from your website and not an outside source. Since, there are maximum chances of the information being fake.
• Restriction of the type of extension files being uploaded on the website is yet another method of security check.
• Renaming files is another way in which the program can be secured. This procedure involves the checking of double-barreld extensions like yourfile.php.gif.
• Changing the permission command for the upload folder so that files within it are not executable.
• All the alterations created by the user should be allowed only when they ‘Login’ into the database. On the other hand the owner of the site should always keep a close watch on all files being uploaded and then make them live.
Mysql Programming Security
Another aspect in php and mysql web development is the protection of the mysql libraries. Therefore, the most important aspect involved in protecting the mysql program is the security of the entire server host.
Securing MySQL is very essential for the smooth running of the website. This is based on Access Control Lists and SSL-encrypted connections, for protecting the php mysql web development program from random users visiting the website.
Some of the vital things to be considered for online site protection are:
• Accessing of the mysql database should not be allowed for any and everyone.
• Privileges to the users should always be accompanied with some restriction. If one can easily connect to the server without any ‘login’ then the security level code of the MySQL server should be rechecked.
• The MySQL database should be void of plain-text passwords. Use programs like MD5 (), SHA1(), or some hashing function for complete protection.
• Do not choose passwords from dictionaries, since they can be hacked easily. Use programs that break the passwords.
Therefore, the successful development of a website through php and mysql web development is complete only when the site owner consults a professional programmer. They expertise in the optimization of the MySql hosting database. This program is dynamic in nature and is an effective tool in the creation of browser-based applications.

Ajax Applications For Your Websites
AJAX enables you to write interactive applications while reducing the amount of data interchanged between the web browser and web server. This results in shorter processing times so you can give your user the ultimate web experience.
AJAX. Asynchronous JavaScript and XML, if you must know what it stands for. Don't let that put you off. Even if it is comprised of technical words and yet another acronym, more importantly, what is it, and why do you need it?
Why to use Ajax?
Mainly to build a fast, dynamic website, but also to save resources.
For improving sharing of resources, it is better to use the power of all the client computers rather than just an unique server and network. Ajax allows to perform processing on client computer (in JavaScript) with data taken from the server.
The processing of web page formerly was only server-side, using web services or PHP scripts, before the whole page was sent within the network.
But Ajax can selectively modify a part of a page displayed by the browser, and update it without the need to reload the whole document with all images, menus, etc...
For example, fields of forms, choices of user, may be processed and the result displayed immediately into the same page.
Remember the internet up until recently? Virtually all web pages were lifeless objects, similar to pages in a magazine, with no intelligence. In order to get a response from a website, you would click a link or press a submit button, and your computer would send a message to the computer hosting the site that it needs to send you back the next page. A little bit like turning to a new colourful but lifeless page in your magazine.
Sure, there were some really great new technologies that came along to make the internet more interesting. Animated images, Flash animations, small embedded applications, and scripts downloaded with the page certainly made the pages a lot more interesting. Yet, when compared to the highly responsive environment of your desktop computer, a web page really could not compete. Click anywhere in your local pc environment and you get an immediate and logical, virtually instantaneous response from the object you clicked, without your entire screen flashing blank and reappearing again from scratch. Do the same on a web page until recently, and usually at best you would have to wait a few seconds for a completely new page to reappear, a newly turned page in your virtual magazine.
Until Ajax. Technically Ajax is actually not a new technology, but a clever grouping of a few existing technologies. What has made Ajax a workable solution is that most people have started using browsers capable of supporting these technologies, often without even realising that their browser wields these dormant superpowers.
Ajax allows your internet page to respond to a user very similarly to the way your local computer desktop environment would. In a well-developed Ajax-based site, when you click on a page object, it responds almost immediately. Any changes to the page happen there and then, without the page disappearing and a new one replacing it. The result? A much more pleasant user experience. Once more, computers are becoming more interactive and responsive.
The concept can be a bit difficult to grasp initially, so here's a simple example from the RealmSurfer website to demonstrate the concept: Ajax example: search page. At first glance this looks like any other search page. Notice that advanced search link underneath the search box? When you click it, notice that you instantly get a whole lot more functionality inserted into the page -- no page refresh. Click the link again and the process reverses itself.
This is just a very simple example of the benefits of building Ajax functionality into your site. To get a look at some really powerful applications, have a look at a few popular Ajax-enabled websites:
Flickr -- one of the first sites to popularise the Ajax phenomenon, it's still one of the best ways to share pictures with your friends and family online. Yahoo was quick to realise the potential, and purchased the company a while back.
Protopage -- create your own customised, interactive home page. From the moment you land on the site, you can move objects around the page as if they are windows on your desktop, and interact with them just as easily.
There are plenty more Ajax-powered sites, and every day a whole lot more become available. What makes this technology so special? Here are a few good contributers:
* It uses relatively well established browser technology -- no plugins are needed, and most browsers these days are fully capable of supporting Ajax-enhanced pages.
* For the most part pages are still recognisable by search engines, meaning that unlike technologies like Flash, search engines will still understand what your page is about.
* It's economical. Instead of downloading a whole page when all you want to know is the weather, a well designed Ajax-based site will only download the information you need, leaving everything else perfectly intact.
* It's fast and responsive. Because much of the programming code that makes an Ajax-based page so useful is downloaded onto your local computer, much of your functionality is very fast and responsive, the same as any locally installed program.
* It's non-proprietary technology. Ajax is a combination of established web standards. You will never have to pay to use it, and neither will the people who program it for you.
