(Aaron Skonnard) Programmers using Visual Basic 6.0 have long bowed to the altar of the ADO recordset. It’s probably the most commonly used data structure in Windows-based applications today. The ADO.NET DataSet is poised to play a similar role in the realm of managed Windows-based applications.

(Adam Young) XAML (Extensible Application Markup Language) is an XML dialect that developers will use to author applications for Longhorn, the next version of the Microsoft Windows operating system. A new user services layer, code named “Avalon,” lets you define a single set of markup pages and code

(Shail Srivastav) In this article I will show how to build and use asynchronous Web services in your application and how you can use the callback method to make your application work in asynchronous state. I made this application to calculate the speedup for the case when you want to run long proces

(Michael S. Mimoso) Service-oriented architectures, XML and Web services may be evolving into viable enterprise computing strategies, but they do come at a price. Parsing, transforming and validating XML puts a drain on server resources and cuts into service levels, according to research done by

(Bob DuCharme) I have several useful little stylesheets that I’ve never mentioned in this column because each is so short that describing it would make for a pretty short column.

Savarese) In the past year or two, the Java platform has been criticized for lagging behind competing platforms in integrating with XML, and Sun Microsystems has been accused of deliberately dragging its feet to adopt XML as part of its distributed computing strategy. Whatever truth there

(Andy Oram) In last week’s article (“From P2P to Web Services: Identification and Addressing”), I examined the ways in which the development of web services might learn some lessons from the peer-to-peer phenomenon of a few years ago. I focused on identification and addressing. In this article I con

(Charles Sterling) I want to create a Windows Application that allows a user to enter/edit/access data that he or she creates without connecting to a remote database. I want all of the data accessing to be local. Is this possible? I was thinking maybe using XML files to store the data and read the

(Nakul Goyal) Since the inception of XML, many developers have wondered why we need XML… How is it better than HTML and what does it do? For starters, XML is far more powerful than HTML, and the power resides in the “X” in XML (which stands for extensible). Rather than providing a set of pre-defin

(Thiru Thangarathinam) Designing an n-tier application means carefully evaluating the different options and paying careful attention to the type of objects being returned from the business logic layer. The client for the business logic layer could be either ASP.NET Web forms or ASP.NET Web services.
