- Migrating
to ASP.NET
This paper looks at some of the specific benefits you can achieve in migrating applications from ASP, and presents five distrinct strategies for a migration, based on its perceived strategic value and your desired timeframe for results. A scorecard with key questions about your migration allows you to quickly arrive at an initial estimate of a migration's complexity. Finally, it outlines the major activities involved in the four phases of a migration project.
- Multi-Language
programming
which has taken language interoperability to new heights, shows that it's possible, but only with the right design, the right infrastructure, and appropriate effort on the basis of both compiler writers and programmers. In this three-part article, I'd like to go deeper than what I have seen published on the topic, to elucidate what it takes to provide true language openness. The experience that my colleagues have accumulated over the last three years of working to port Eiffel on .NET, as well as the countless discussions we have had with other .NET language implementers, informs this discussion.

Hosting Guide
ASP.NET Hosting is a web service hosting provided on Windows 2000 server or Windows 2003 Server platform, which supports ASP.NET framework. ASP.NET is the successor of the highly successful classic ASP. ASP.NET is a powerful server-side technology utilizing the Microsoft .NET framework. ASP.NET pages have ".aspx" extension and are executed on the server. ASP.NET hosting is practically offered by all Windows hosting companies. Different hosting companies offer different ASP.NET hosting plans, with variety of features. The most popular database backend used in hosted ASP.NET web applications is MS SQL Server. ASP.NET hosting plans frequently offer MySQL and MS Access databases, as well as variety of ASP.NET components.

Alliance Tutorial
In Classic ASP, we were having only six objects and we have only less to learn. But now, in ASP .NET (V1 Framework) we have around 4,000 classes and 78,000 methods and properties. This is a beginner's tutorial for ASP .NET. All examples have been worked out in VB. To start with, I am starting with three web server controls. I will add many other controls with ready to use examples in the coming days. I will list the control that we are going to learn. Also, I have a bulletted list of information. This information is nothing but the list of things that you will learn from the control listed.

We will be creating ASP.NET data driven Master/Detail pages as well as insert, update, and delete pages records with ASP.NET. You will also learn how to build forms using the new ASP.NET server controls, how to implement ASP.NET client side field validation, and how to develop custom ASP.NET controls. In addition to coverage of DWMX features Dot NET News shows how to implement ASP.NET folder level security on your content management pages and discusses how to authenticate global site users with the ASP.NET authentication service. The complete code of this tutorial is available as a download.
- ASP.NET.4GuysFromRolla
ASP.NET is Microsoft's dynamic website technology, enabling developers to create data-driven websites using the .NET platform. ASP.NET version 1.0 was first released in January 2002, with ASP.NET version 1.1 released in April 2003. Version 2.0 of ASP.NET was released in November 2005. (For more on ASP.NET version 1.x, see the 1.x article index; for more on 2.0, refer to the 2.0 article index.)The site navigation features in ASP.NET 2.0 make it easy to define a site map and implement common navigation UI elements, such as a breadcrumb, treeview, and menu. Due to its use of the provide model, you can dictate how to serialize the site map. ASP.NET 2.0 ships with a default implementation that serializes site map information to an XML-formatted file (Web.sitemap, by default), but as we saw in Part 4 this logic can be customized to garner site map information directly from the file system or through a SQL Server database table.
- Object
Oriented Programming for VBscripters
If you want to make the move to .NET and feel intimidated by object-oriented programming (OOP), this article is designed to ease any level VBScripter (ASP) into .NET by clarifying some OOP concepts.Think of an "object" as simply a container that could have state, behavior, and identity. Objects are typically represented as a "class" and are considered to be a custom "type." Every single program you create will be composed entirely of classes. Let's start with the basics. There are a few big differences between classic ASP and .NET, more specifically VBScript and C#. With VBScript, all variables are of type "variant," which means they can be treated as any data type you wish. Any action taken when performing some action on the variable was determined by the action and the data in the variable itself.
- Microsoft .NET Framework FAQ
The Microsoft .NET Framework is a platform for building, deploying, and running Web Services and applications. It provides a highly productive, standards-based, multi-language environment for integrating existing investments with next-generation applications and services as well as the agility to solve the challenges of deployment and operation of Internet-scale applications. The .NET Framework consists of three main parts: the common language runtime, a hierarchical set of unified class libraries, and a componentized version of Active Server Pages called ASP.NET.
- Debugging
and Tracing in ASP.NET
Before Web development was popular and most applications were stand alone programs debugging strategies depended a lot on how and where they were being developed. When developing in C/C++ printf(...) was a favorite debugging tool on both UNIX and DOS environments for programmers. That changed when Integrated Development Environments--IDEs--like Borland's Turbo C++ and Microsoft's Visual Studio came along. These allowed stepping through code and watching local and global variables in a GUI as each line of code was executed. Suddenly, debugging was much more efficient. All that changed once again with the Web programming model. Debugging was once again much harder and reduced to print statements. Server side debugging before Visual Studio .NET was never up to the mark. Even with Visual Studio .NET server side debugging still does not have all the bells and whistles that the older IDEs had while developing stand-alone applications.
- The .NET Revolution
Microsoft is about the change the way we do web developmentagain. Just a few years ago they introduced their Active Server Page technology, otherwise known as ASP, that allowed developers to directly embed code within their web pages that was executed on the server with the results sent back to the client. While this type of embedded code was a dream come true to many developers who were fed up with CGI and the like, it still left much to be desired. From a developer's perspective, pages designed with ASP technology can be lengthy, difficult to read and just plain sloppy. Not only that, but the developer is restricted to using VBScript, a watered-down incarnation of Visual Basic or JScript, Microsoft's attempt at reinventing the wheel that is JavaScript. Neither of these languages is very powerful feature-wise, and being scripting languages, they are not strongly typed (simply put, strongly typed languages are those languages that require specific variable and type declarations and often adhere more strictly to syntactical and logical requirements) which tends to make these languages and ASP pages less efficient overall.
- Building Secure ASP.NET Applications
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.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.
- Event
Logging in .NET
In an earlier article we had discussed how new tracing and debugging techniques in .NET make debugging easier. In this article we will view the event logging API that comes with .NET. We will also create a small library that can be used in most enterprise level applications that overcomes a few shortcomings of the standard .NET API for event logging.All the classes required for logging events to the windows event log are in the System.Diagnostics package. The most important class is the EventLog class. This allows reading and writing of event log entries. However, before any logs can be written an EventSource must be defined.
- ASP.NET
Web Programming
Any real website is generally made up of a lot of pages, images, XML/XSL files, stylesheets, databases, and other types of document. It's very common to have many hundreds or even thousands of files for a single website. During development of the site these files will usually be modified several times. This will also continue after deployment, since no application is ever really finished ? particularly when we can redeploy to all our users at once. As a result, an integral part of any development work is having some kind of maintenance system
- ASP
.Net Fundamental
After working with ASP.Net for over a year, and participating in the Microsoft ASP.Net newsgroups for quite awhile, I have observed that many people who are new to ASP.Net are having some fundamental difficulties understanding how it actually works. This is particularly important with ASP.Net, much more so than with ASP. Why? Because ASP has a fairly straightforward approach to creating dynamic content, and is procedural. ASP.Net is object-oriented, and has a number of features built in which seem to confuse people. For example, with ASP it was fairly obvious to most of us that there is an impenetrable gulf between the server and client, because HTTP is stateless, meaning that the browser and server only respond to individual page requests, and do not maintain any kind of state between requests.
- The
ASP.NET Pages Cycle
When a page request is sent to the Web server, whether through a submission or location change, the page is run through a series of events during its creation and disposal. When we try to build ASP.NET pages and this execution cycle is not taken into account, we can cause a lot of headaches for ourselves. However, when used and manipulated correctly, a page's execution cycle can be an effective and powerful tool. Many developers are realizing that understanding what happens and when it happens is crucial to effectively writing ASP.NET pages or user controls. So let's examine in detail the ten events of an ASP.NET page, from creation to disposal. We will also see how to tap into these events to implant our own custom code.
