XML Schemas: Take Advantage of Existing External XML Schemas with a Custom Import Framework in ASP.NET
Scott Short - December 2002
Over the years, many industry-standard XML schemas and dialects have been developed. These industry-specific schemas embrace the original purpose of XML and are extremely valuable in promoting and supporting B2B interaction. Unfortunately, the ASP.NET Web Services runtime does not allow developers to directly reference external schemas from within their XML Web Services interface (the WSDL file). This article builds an external schema framework as an extension to the ASP.NET Web Services runtime to enable you to reference external schemas within your XML Web Service interface.

Passport Secure Sign-In: Provide Your Users with Secure Authentication Capabilities Using Microsoft .NET Passport
Michael Kogotkov-Lisin - September 2002
Secure sign-in, a new feature in version 2.0 of the .NET Passport single sign-in and profile service, is a functionality that will be especially useful for sites containing confidential information or anywhere security is a primary concern. Such sites include banks, medical sites, and so on. Secure sign-in is as safe as any SSL-based Web site login used today and provides a way to virtually eliminate vulnerability to replay and dictionary attacks.This article explains secure sign-in and demonstrates how you can implement this feature with very little effort in either ASP using the Passport.Manager COM object or in ASP.NET using the .NET class PassportIdentity.
HTTP Pipelines: Securely Implement Request Processing, Filtering, and Content Redirection with HTTP Pipelines in ASP.NET
Tim Ewald and Keith Brown - September 2002
ASP.NET is a flexible and extensible framework for server-side HTTP programming. While most people think of ASP.NET in terms of pages served, there is a lower-level infrastructure sitting beneath this page model. The underlying plumbing is based on a pipeline of app, module, and handler objects. Understanding how this pipeline works is key if you want to get the most out of ASP.NET as an HTTP server platform, while making your process more efficient, and keeping your server secure. This article introduces the architecture of the pipeline and shows how you can use it to add sophisticated functionality to an ASP.NET-based app.
Tamper-Resistant Apps: Cryptographic Hash Algorithms Let You Detect Malicious Code in ASP.NET
Jason Coombs - September 2002
Cryptographic hash algorithms produce fixed-length sequences based on input of arbitrary length. A given input always produces the same output, called a hash code. Using these algorithms, you can compute and validate hash codes to ensure that code running on your machine has not been tampered with or otherwise changed. ASP.NET provides a software mechanism for validating hash code fingerprints for every page requested by a client. In this article, the author shows how to use hash codes with ASP.NET applications to detect tampering and prevent malicious code from running when tampering is detected.

ASP.NET: Intercept, Monitor, and Modify Web Requests with HTTP Filters in ISAPI and ASP.NET
Panos Kougiouris - August 2002
There can be many reasons to reroute incoming Web requests. For instance, sometimes it's necessary to redirect a browser to a page based on user criteria without passing long lists of parameters in the URL. In the past, the only way to intercept such page requests and send them elsewhere was with ISAPI. Now, in ASP.NET, the IHttpModule interface provides notification of server requests, and lets you easily reroute them based on criteria other than browser type or version. Here the author demonstrates the use of IHttpModule for interception and explains the use of ISAPI filters for anyone who isn't yet using ASP.NET.
Commerce with ASP.NET: Leverage the Authentication and Form Validation Features of ASP.NET to Bolster Your Commerce App
Jason Lefebvre and Robert Lair - August 2002
If you're planning to build an e-commerce site, you'll be pleased to see that ASP.NET makes it easier than ever. Existing controls can be used and extended to add a great deal more functionality than you might expect. In this article, forms-based authentication is used to verify the identity of users and make certain areas of the site, such as the check-out page, inaccessible to unauthorized users. The power and flexibility of validation controls are demonstrated using the CustomValidator control to connect to a Web Service that verifies addresses. A shopping cart is then implemented in ASP.NET using the DataGrid, and finally, credit card authorization and billing are performed.

To demonstrate the use of Windows Forms over the Web, the author takes his existing app, Wahoo!, and ports it to Windows Forms. In doing so, he discusses versioning, linked files, security, storage isolation, the deployment model, and everything else you need to get started building your own Windows Forms apps for the Web.
Bug Tracker: Build a Configurable Web-Based Bug Management Tool Using ADO.NET, XML, and XSLT
Roy Margolis - July 2002
One of the most significant features of ADO.NET is its integration with XML. Developers can either use an ADO-like API to access the data or work directly with an XML representation of the data. This article demonstrates how both of these techniques can be used together to create Web applications that take advantage of XML standards such as XSLT. The example presented here is a bug tracking application built using C# and the.NET Framework. The development of the application covers several topics including data access using ADO.NET, the presentation of data using XSLT stylesheets, and the integration of ADO.NET with the .NET XML Framework.

ASP.NET: Develop Polished Web Form Controls the Easy Way with the .NET Framework
David S. Platt - June 2002
Pre-built custom controls make application design easier and faster and allow you to maintain UI consistency. However, prepackaged controls can be big and slow, and are OS-specific. For those who don't want to use prepackaged controls, Visual Studio .NET provides controls for Web Forms similar to those found in Windows Forms, including label and textbox, and new additions such as the DataGrid, all of which you can customize. If you want to design your own controls, the .NET Framework provides inheritable classes that take care of all the nasty stuff you want to avoid, including page lifecycle, maintaining state across invocations, and browser detection. This article discusses these concepts, as well as eventing, rendering, and client-side scripting.
C#: XML Comments Let You Build Documentation Directly From Your Visual Studio .NET Source Files
J. Andrew Schafer - June 2002
C# allows developers to embed XML comments into their source files-a useful facility, especially when more than one programmer is working on the same code. The C# parser can expand these XML tags to provide additional information and export them to an external document for further processing. This article shows how to use XML comments and explains the relevant tags. The author demonstrates how to set up your project to export your XML comments into convenient documentation for the benefit of other developers. He also shows how to use comments to generate help files.
Return of the Rich Client: Code Access Security and Distribution Features in .NET Enhance Client-Side Apps
Jason Clark - June 2002
Rich clients employ many of the features and conveniences of the operating system they run on, and the list of these features has been growing since the dawn of the PC. But as apps have migrated to the Web, the trend towards increasing client-side functionality has ground to a virtual halt. There are several reasons for this; chief among them are security and deployment problems. But that's all about to change. With the .NET Framework, you can participate in building the distributable rich client of the future. In this article, the author enumerates the pertinent features of .NET that will allow you to build safe, easily deployable controls. The features discussed include managed code, code access security, versioning control, Windows Forms classes, and isolation.

Virus Hunting: Track and Report Server Attacks Quickly and Easily with the .NET Networking Classes
G. Andrew Duthie - April 2002
To help stop the spread of worms, viruses, and other hostile activity, it is important to track down and report the servers used in these attacks along with those used to send spam. Many Web administrators, however, don't take the time to track them because the manual process can be quite cumbersome. The Microsoft .NET Framework comes to the rescue with several networking classes, including the Dns class and the TcpClient class, that abstract away the complexity of performing DNS and WHOIS lookups. These classes make it easy to create a simple, straightforward ASP.NET-based utility for performing these lookups and automating this very important task.
ASP.NET: Selectively Enable Form Validation When Using ASP.NET Web Controls
James M. Venglarik II - April 2002
Sometimes the extra controls that come with Visual Studio .NET can be a bit inflexible or they just don't provide enough functionality or flexibility for all situations. The ASP.NET form validation controls, while powerful and easy to use, require that the entire page be valid before it's submitted back to the server. Through the use of the new object-oriented features of Visual Basic .NET, it is possible to extend their functionality to overcome this limitation. This article tells you how and helps you decide when it's a good idea to keep validation on the client and when you'd be better off disabling it.

Features such as Remote administration, caching, and metabase improvements, as well as custom isolation and security enhancements, make IIS 6.0 the Web server of the future.
ASP.NET: Create Snazzy Web Charts and Graphics On the Fly with the .NET Framework
Scott Mitchell - February 2002
Knowledge workers can understand data more effectively when raw numbers are presented in a graphical format. This is especially true when displaying database information on a Web page, where a simple chart can make the difference between a dry presentation and a vivid data source. In the past, creating dynamic, data-based charts on the fly in ASP required purchasing a third-party, image-generating COM component. Now with ASP.NET, developers can access the .NET Framework's drawing classes directly with C# to create dynamic images and charts.

Generative Programming: Modern Techniques to Automate Repetitive Programming Tasks
Chris Sells - December 2001
Even when developers have recurring computer-readable metadata to process and a clear idea of how code should be structured, they can still find themselves in need of a technique to automatically generate the code to avoid the drudge work of repeatedly writing and tweaking it. Generative programming is a technique that addresses this problem. Using generative programming techniques, you can solve software engineering problems in families, rather than individually, saving time and coding effort. This article describes these techniques, and builds a sample template-driven code generator. The article also lists existing utilities that have been built with generative programming techniques, as well as actual code generators.

ISAPI Extensions: Creating a DLL to Enable HTTP-based File Uploads with IIS
Panos Kougiouris - October 2001
The MIME-compliant content type, called multipart/form-data, makes writing HTML that uploads files almost trivial. On the server side though, ASP does not have a way to access data in the multipart/form-data format. The most flexible way to access the uploaded file is through a C++ ISAPI Extension DLL. This article describes a reusable ISAPI extension DLL that allows you to upload images and files without writing C++ code. It is coupled with a few COM components that make it readily reusable for ASP development. With .NET, this whole process is much easier, and this article shows preliminary code that uploads files using ASP.NET features.
ISAPI Filters: Designing SiteSentry, an Anti-Scraping Filter for IIS
Rodney Bennett - October 2001
The Microsoft Internet API for IIS, ISAPI, sits between the client and the Web server. Therefore, you can access the HTTP data stream before IIS gets to see it. The project in this article takes advantage of the ISAPI architecture to create a filter that monitors access to a Web site to determine if visits are from typical users or from automated processes designed to pilfer information from your site. The author tracks the regularity of visits to the site to determine the likely source. Once the determination is made, the app either redirects the user or continues to track information about those hits.

To make the most efficient use of that information, it must be readily accessible, easy to identify, and simple to navigate. SharePoint Portal Server 2001 unifies information by allowing members of any organization to create, share, and publish documents from a single access point. This article covers the services in SPS that can help an organization improve workflow and information management.
C# and the Web: Writing a Web Client Application with Managed Code in the Microsoft .NET Framework
Avi Ben-Menahem - September 2001
When the author wanted to build a middleware Web client to connect to other applications over the Internet, he realized that the XMLHttpRequest COM object was not sufficient for his purposes. In order to build a Web client using managed code, the author had to use the HTTPWebRequest and HTTPWebResponse classes provided by the Microsoft .NET framework. These classes are used in the sample project as a substitute for the less powerful XMLHttpRequest COM object, allowing the author to build a full-featured Web client. They also take advantage of all the benefits that the CLR and managed code have to offer.
ASP.NET: Collect Customer Order Information on an Internet Site Using XML and Web Forms
Jeff Jorczak - September 2001
XML has quickly become the new data structure standard for everything from database access to cross-platform computing. XML is typically considered to be a vehicle for data exchange, dynamic data presentation, and data storage. However, the potential of XML far surpasses those limited applications. This article examines one new use: the gathering of data across a number of forms in an ASP.NET Beta 1 framework application. The sample program is a Web app used for ordering pizza. It uses ASP and C# to gather order information and then stores it in XML. To build the application, several concepts are explained, including data collection, order persistence using cookies, grouping input forms, and formatting the data for display.

SQL and XML: Use XML to Invoke and Return Stored Procedures Over the Web
Dave Grundgeiger, Anson Goldade, and Varon Fugman - August 2001
Front-end developers frequently want to add functionality to the presentation tier of an n-tier architecture, but such requests can require changes on all tiers just to get the data and present it. This process can be made easier and more flexible by using SQL Server stored procedures to automate the delivery of data in XML format from the database to the front-end components. In the component presented here, stored procedures are invoked by XML strings, XML is returned, converted using XSL, and presented to the client in HTML. The technique supports rapid changes yet doesn't sacrifice the n-tier approach. This approach can be used with either SQL Server 7.0 or SQL Server 2000.

WSS is based on Internet standards, therefore data can be accessed through URLs, an Exchange OLE DB provider, drive mapping, XML, and Web Documenting and Versioning (WebDAV). This article discusses the WSS schema and how to extend the default schema for custom data. A sample application that uses a custom schema and a custom form to display WSS data is available for download.
ASP.NET: Web Forms Let You Drag And Drop Your Way To Powerful Web Apps
Jeff Prosise - May 2001
Web Forms have the potential to change Web programming by introducing a new programming model built around server-side controls-a model in which controls render their own UIs by generating HTML to return to clients and firing events that are handled by server-side scripts. Since all the action takes place on the Web server, virtually any browser can run a Web Forms app. And thanks to Visual Studio .NET, building a Web Forms app is a lot like using Visual Basic: just drop a control onto a form then write an event handler. This article describes the Web Forms programming model, how it fits with ASP.NET, and introduces DataGrid, TextBox, and other classes in the .NET Framework class library.

Beyond ASP: XML and XSL-based Solutions Simplify Your Data Presentation Layer
Scott Howlett and Jeff Dunmall - November 2000
The combination of XML and XSL can provide a powerful alternative to ASP development. This article presents arguments for building even small-scale Internet applications on the XML model. An example written with traditional ASP programming is compared to the same example written with XML and XSL in order to show the benefits of this approach. The example is followed by nine good reasons to make the switch. These reasons include separation of presentation and data, reusability, extensibility, division of labor, enhanced testing, and legacy integration. The XML/XSL solutions described hold the promise of greater simplicity, flexibility, and durability than ASP solutions built the traditional way.

Taming the Stateless Beast: Managing Session State Across Servers on a Web Farm
John Papa - October 2000
Running a Web farm means managing session state across servers. Since session state can't be shared across a Web farm with Internet Information Services 5.0, a custom solution is required. One such solution using a tool called the session manager is described here. The article begins with a description of the SQL Server database used to store state information, the stored procedures used to update it, and the retrieval of session data. ASP code drives the session manager tool and the COM and COM+ components that run the stored procedures.

Active Server Pages+: ASP+ Improves Web App Deployment, Scalability, Security, and Reliability
Dave Sussman - September 2000
ASP has been rebuilt from the ground up. The result? Active Server Pages+. ASP+, with a host of new features, provides for easier to write, cleaner code that's simple to reuse and share. ASP+ boosts performance and scalability by offering access to complied languages; development is more intuitive thanks to Web Forms; and an object-oriented foundation facilitates reuse. Other important features include page events, Web Controls, and caching. Server Controls and improvements in data binding are also new with ASP+. Libraries for use with ASP+, and the Microsoft .NET Framework which allows custom business functions to be exposed over the Web, provide more new development opportunities.

Web Security: Putting a Secure Front End on Your COM+ Distributed Applications
Keith Brown - June 2000
The Internet requires that developers provide a different security model for clients than is used on a closed network. Because it would be too resource-intensive for both the client and server to prove their identity to each other, you need to look at other ways to ensure secure communications. This article covers the options, from digital certificates to public and private key encryption to Secure Sockets Layer and Web certificates. The discussion covers the installation of certificates in Microsoft Internet Information Services along with other options specific to IIS. This article was adapted from Keith Brown's Programming Windows Security (Addison-Wesley), due out in July 2000.

Using Server-Side XSL for Early Rendering: Generating Frequently Accessed Data-Driven Web Pages in Advance
Paul Enfield - April 2000
Dynamic data-driven pages have become the basis of many cutting-edge Web sites. Early render systems can provide better performance and maintainability for data-driven Web sites by generating frequently accessed pages that contain less-volatile information ahead of time. We'll show you an example of a server-side solution that uses Extensible Stylesheet Language (XSL) to merge data and layout information into HTML that is compatible with just about any modern Web browser. Using these techniques to render Web pages early can reduce the load on your database back end and increase performance for your users.
New Directions in Redirection: Microsoft Internet Information Services 5.0 Provides Two New Methods
Ram Papatla - April 2000
Internet Information Services (IIS) 5.0 provides several enhancements to its support for ASP-based Web development, including two new server-side redirection methods: Server.Transfer and Server.Execute. Rather than redirecting requests with a round-trip to the client, these new methods can be used to transfer requests directly to an ASP file without ever leaving the server. While this functionality doesn't replace the Response.Redirect method used by IIS 4.0, you can take advantage of it to implement better application flow control mechanisms and to handle errors more efficiently. The different redirection options are described, along with some tips and tricks for implementing them on your own site.

SQL Server 2000: New XML Features Streamline Web-centric App Development
Joshua Trupin - March 2000
With XML support in SQL Server 2000, you can query SQL over HTTP with a URL, bring the data down to the browser, and manipulate it on the client machine. By adding Internet Explorer 5.0 to the mix and using XSL to convert the XML to HTML, you can lighten the load on your database server. Going still one step further, by using Vector Markup Language you can even create drawings on the fly using the data from your SQL queries. This article illustrates this combination of technologies by leading you through the creation of a Web app that queries a digitized street map database that's been imported into a SQL Server database, sorts and displays the data using XML, and draws maps using VML.
Build an Easy Maintenance Intranet Site: Using Office Docs, File System Object, and OLE Structured Storage
Josef Finsel - March 2000
If you've ever needed to build an easy-to-maintain intranet site, here's a solution based on Microsoft Office documents. Many sites require constant updating of their HTML, but the use of Word documents can simplify the process. This article details the construction of a human resources site that exploits the File System Object (FSO), OLE Structured Storage, and ActiveX capabilities of Word documents. This allows the HR staff to copy their revised or newly created Word files to the site, dynamically generate a list of links to their files, and free IS from the constant recoding of HR updates into new HTML pages.
