ASP.NET

ASP.NET Web Developer's Guide
By Mesbah Ahmed, Chris Garrett, Jeremy Faircloth, and Chris Payne
Since 1996, ASP programmers have faced one upgrade after another, often with no extremely visible advantages until version 3.x—it’s been quite a wild ride. Now we have the first significant improvement in ASP programming within our grasp —ASP.NET. Our reliance on a watered-down version of Visual Basic has been alleviated now that ASP.NET pages may be programmed in both Microsoft’s new and more powerful version of Visual Basic or the latest version of C++: C#, which is more Web friendly.ASP.NET allows programmers and developers to work with both VB.NET and C# within the same ASP.NET page. .NET itself is a milestone for Microsoft; it marks Microsoft’s entry into the “run once, run everywhere” compiler market alongside Java and Ruby. .NET is also notable for its extreme flexibility; unlike the other choices available, .NET allows the programmer to use any number of .NET-compliant languages to create its code (however, as of this writing, only VB.NET and C# are allowed for ASP.NET) and have it run anywhere through the robust .NET Framework.Visual Basic and C++ have undergone changes as well; Visual Basic was already somewhat Web-oriented through its sibling,Visual Basic Script (VBS).
Since VBS was not visually orientated, like Visual Basic, this meant that a lot of the prewritten code employed by Visual Basic did not create performance issues.This did mean, however, that VBS was not graced with an IDE to debug or troubleshoot with, making the server logs and the browser error messages a programmer’s only hope of figuring out what went wrong and where.The lack of an IDE led to several complications and eventually programmers had to create their own error-handling system, usually consisting of a log file and e-mail notification.
VBS had another obstacle to overcome in attempting to offer programmers more than what originally was basically a scaled-down version of Visual Basic.VBS lacked many of Visual Basic’s strong features due to the way that the IIS was limited at the time, especially with object creation and cleanup. Programmers experienced code or objects locking up before destruction, rampant memory leaks, and even buffer overflows that were caused by IIS, not by the code itself.
With .NET in general,Visual Basic and VBS are now one and the same. All of the Web-oriented abilities of VBS have been given to Visual Basic and it has received a significant retooling of the language and syntax. Many previous problems, such as poor memory management and object control, have been resolved by the .NET Common Language Runtime (CLR) and internal programming additions, such as the inclusion of the Try/Catch error-handling system and more low-level abilities than before. All in all,Visual Basic can now be called a true programming language.
C++ retained all the aspects that made it a powerful programming language, such as its excellent object control and error-handling techniques, in its new version, C#. It has now gained a very good IDE as well as being more Web-based, a trait that can be attributed to the .NET Framework and ASP.NET. It is expected that many programmers will still use C# for object control while combining it with Visual Basic’s ease of use for GUI and presentation.
This book is meant to show all ASP programmers, new and old, just how powerful ASP.NET now is. Unlike ASP 1.x through 3.x, which worked in Windows 95 through the Personal Web Server tool, you will need at least Windows 2000, all the latest service packs, Internet Explorer 6, IIS 5.x (up to date), and the .NET SDK installed. As of this writing, the latest version of .NET is Beta 2, which covers the framework,ASP, and its programming languages. Remember, this book is meant to be an introduction to ASP.NET, not VB.NET or C#. If you need a good book on VB.NET or C#, I recommend looking to two other books published by Syngress Publishing: The VB.NET Developer’s Guide (ISBN 1-928994-48-2) and The C#.NET Web Developer’s Guide (ISBN 1-928994-50-4).

An Introduction to ASP .NET using Visual Basic .NET
By Peter McMahon
This book is aimed primarily at three groups of people. First, those readers who are Visual Basic programmers and wish to learn how to develop Web applications using ASP.NET by applying what they’ve learned in Visual Basic. = Second, current ASP programmers who wish to learn how to become more productive using the completely new, yet familiar, ASP.NET programming model and the Visual Studio .NET IDE. Third, current ASP and Visual Basic programmers who wish to merge their skills to increase their productivity.
This book assumes no previous knowledge of building Web applications or even simple, static Web pages using hand-coded HTML. There is a chapter dedicated to getting Visual Basic programmers without any HTML or Web building knowledge up to speed. However, this book does assume previous experience with the Visual Basic programming language or a previous subset thereof, VBScript. Included is a section showing the differences between VBScript (and previous versions of Visual Basic) and the Visual Basic .NET language that should prevent some of the subtleties of the language from causing any problems. Knowledge of object-oriented programming is advantageous, although not essential.

ASP.NET AJAX Roadmap
Microsoft ASP.NET AJAX documentation includes overviews, tutorials, and API reference topics.
IntroductionMicrosoft ASP.NET AJAX enables you to quickly create Web pages that include a rich user experience with responsive and familiar user interface (UI) elements. ASP.NET AJAX provides client-script libraries that incorporate cross-browser ECMAScript (JavaScript) and dynamic HTML (DHTML) technologies, and it integrates them with the ASP.NET 2.0 server-based development platform. By using ASP.NET AJAX, you can improve the user experience and the efficiency of your Web applications.
Why Use ASP.NET AJAX?ASP.NET AJAX enables you to build rich Web applications that have many advantages over Web applications that are completely server-based. ASP.NET AJAX applications offer:
Improved efficiency by performing significant parts of a Web page's processing in the browser.
Familiar UI elements such as progress indicators, tooltips, and pop-up windows.
Partial-page updates that refresh only the parts of the Web page that have been updated.
Client integration with ASP.NET application services for forms authentication and user profiles.
Integration of data from different sources through calls to Web services.
A framework that simplifies customization of server controls to include client capabilities.
Support for the most popular and generally used browsers, including Microsoft Internet Explorer, Mozilla Firefox, and Apple Safari.

Building Secure ASP.NET Applications: Authentication, Authorization, and Secure Communication
By J.D. Meier, Alex Mackman, Michael Dunner, and Srinath Vasireddy
This guide presents a practical, scenario driven approach to designing and building secure ASP.NET applications for Windows 2000 and version 1.0 of the .NET Framework. It focuses on the key elements of authentication, authorization, and secure communication within and across the tiers of distributed .NET Web applications. (This roadmap: 6 printed pages; the entire guide: 608 printed pages)
This guide focuses on:
Authentication (to identify the clients of your application)
Authorization (to provide access controls for those clients)
Secure communication (to ensure that messages remain private and are not altered by unauthorized parties)
Why authentication, authorization, and secure communication?Security is a broad topic. Research has shown that early design of authentication and authorization eliminates a high percentage of application vulnerabilities. Secure communication is an integral part of securing your distributed application to protect sensitive data, including credentials, passed to and from your application, and between application tiers.
There are many technologies used to build .NET Web applications. To build effective application-level authentication and authorization strategies, you need to understand how to fine-tune the various security features within each product and technology area, and how to make them work together to provide an effective, defense-in-depth security strategy. This guide will help you do just that.

Inside ASP.NET Web Matrix
By Alex Homer and Dave Sussman
During its relatively short but spectacularly successful life, Microsoft® Active Server Pages (ASP) has grown from a simple scripting environment for creating dynamic Web pages into a powerful and easy-to-use platform for fully-fledged Web application development. In its latest incarnation, ASP.NET, it provides a complete solution for building almost any type of interactive user interface, as well as for implementing extensive back-end processing operations.
However, despite the many powerful features of ASP, choosing a comprehensive and usable development environment in which to create ASP applications was never easy. Many third parties provide ASP support in their products, for example HomeSite and Macromedia UltraDev (among others) support ASP 3.0, and, of course, Microsoft's own Visual Studio 6.0 included InterDev – which was also available as a standalone product.
With the advent of .NET, support for ASP.NET development has been fully integrated into Visual Studio .NET. It provides an extremely powerful and usable environment for ASP.NET development in the guise of Web Forms, as well as the more traditional types of application (Windows Forms). And now Visual Studio .NET is joined by another Microsoft product, namely the Microsoft ASP.NET Web Matrix Project (referred to from here on in as "Web Matrix").
At the time of writing, Web Matrix has just been released as a Beta 1 product. The whole nature of the Microsoft ASP.NET Web Matrix project is that it will develop and grow based on feedback from the community that uses it, so the feature set will evolve over time. You should also keep in mind that, as this is a Beta product, there are quite a few features that are not yet fully implemented (so some things you may expect to see are missing).
However, even at this stage Web Matrix is an extremely usable and efficient tool, and certainly well worth installing and experimenting with. In time, it will, without doubt, mature and be extended to provide many more of the features required for building Web sites and Web applications using ASP.NET.

Moving to ASP.NET: Web Development with VB .NET
By Steve Harris and Rob Macdonald
BY NOW, MOST DEVELOPERS will have heard of ASP.NET and will have seen it in action. In fact, it’s a pretty sure bet that if you’ve bought this book then you already have it installed, maybe with Visual Studio .NET, and there’s a good chance you’ve tried a few things out. You probably already know that ASP.NET brings an objectoriented and event-driven programming model to the world of Web development and that it can dramatically simplify the structure and creation of Web applications. You might, like us, be really excited about the possibilities and improvements it brings, or you might just see it as a tool you can use to save a bit of time so you can get to the game earlier or spend more time with your kids. Either way, you can’t afford to ignore it—ASP.NET is big news and plays a key role in Microsoft’s .NET strategy.
ASP.NET solves many of the problems that currently face Web developers, and it greatly simplifies the tasks of creating, debugging, and deploying Web applications. It’s radically different from its predecessors in many ways, but it shares a common heritage and background to some. It requires that you learn new skills and forget about some you already have. It’ll take time to master, but that investment will be repaid many times over once you start working with it in earnest. In short, it’s what many Web developers have been asking for over the past few years.

ASP.Net with C# - The Basis
By Vijay Mukhi
ASP.Net provides the most powerful environment for development of sophisticated, real-life business applications. It was only natural for us to get sucked into the vortex of the exciting opportunity that this language provides, to satiate our technical appetite. This book presents a realistic tableau of the vast repertoire of features of the ASP.Net language. We have scythed through the maze of technological jargon to present to you, in a simple yet comprehensive manner, all the salient features of the language.
The book commences with the assumption that you are a programming tyro, with no previous knowledge of ASP.Net or C#. It however, expects you to have a working knowledge of the Hyper Text Markup Language (HTML). The book covers the length and breadth of the ASP.Net framework. Since the C# language has been used for programming, the fundamentals of this language have also been covered.
The book begins with the basics of the ASP.Net and C#. Thereafter, it moves on to the built-in controls of ASP.Net. Next, it demonstrates how you can build your own custom controls. The text then veers on to the concepts of the built-in C# classes, and shows you how to build your own custom classes. It also covers the myriad aspects of handling databases, advanced concepts of controls, mysteries of Cookies, CGI Progamming and state management,Web Services and finally a Class Browser Application. It finally winds up with a peek into the security issues of designing an Internet application using ASP.Net. Thus, you’ll be able to appreciate, that a vast array of technical concepts of ASP.Net have been covered by this book.
This book is teeming with examples and explanations that discuss each concept threadbare. The various disparate concepts have been woven together to create a beautiful tapestry of the ASP.Net language. It has always been our modus operandi to break up large programs into smaller fragments, comprehend each fragment thoroughly and subsequently, synthesize all the fragments together to retrieve the original program. The same strategy has been employed in this book also. Each concept has been substantiated with examples so that you can see how each concept is implemented in real-life applications.
In our books, we have presented examples that emulate a concept supplied in the documentation, or some idea we found on the Internet. However, some of the concepts introduced are purely ours, and thus original. As far as we are concerned, you are free to use our accepted wisdom, as long as someone somewhere in the world benefits from it.
We are sanguine that this book will go a long way in providing ample food for thought, to sate the technological hunger of your minds. We implore you to put in sedulous effort in mastering this language, by reading all the material provided to you in this book with sincerity, and also by trying out all the examples that have been presented. We are confident that on doing so, you will be able to scale dizzying heights in the world of Internet programming.
