Since 1998, DevX has helped people start businesses, build websites, and provide enterprise technology to people globally. Interviewing the likes of Microsoft’s co-founder, Steve Ballmer, the publication brings comprehensive, reliable, and accessible insights to the Internet.
he focus of this issue is best practices and techniques. From testing to free tools you can use with ASP.NET, we discuss several topics that are important to developers. I
henever you gather multiple travel veterans in the same location for long enough, sooner or later the discussion turns to travel horror stories. I’ll admit that it’s just August as
utomated unit testing lets a team exercise its entire code base against a battery of tests, facilitating a quick, reactive environment by providing instant feedback during development. When developers can
n real life, sequences aren’t easy to control. Once something is set in motion it is difficult to manipulate discrete portions of that movement. And of course, in real life
ode reuse has been a mantra of software development for decades. .NET provides for code reuse in many ways including inheritance, components, and of course the indispensable function. Visual Studio
hen you’re unit testing, you often want to test an individual unit of code without testing its dependencies. One common solution to this problem is to utilize the mock-object testing

ne of the language enhancements in .NET 2.0?available in both VB.NET 2005 and C# 2.0?is support for partial classes. In a nutshell, partial classes mean that your class definition can
As you know, VBScript doesn’t support the declaration of optional parameters in subroutines or functions. So, if you have a function declared as: Myfunction(p1,p2,p3), to simulate optional parameters, you’d have
This tip is an extension of a Design Pattern called “Service Locator” for the J2EE architecture. Generally, the “Service Locator” pattern returns a home object by merely accepting a string,
You can use STL binders to use binary function objects as unary function objects in many STL algorithms which need them. Suppose you need to find the count of strings
The Java API provides a class called java.util.Observable which can be extended by any Java class. The child class can then be an “observable” class and other objects can “observe”
n the old days, building mobile applications involved using the ASP.NET mobile controls which were a subset of the larger ASP.NET. ASP.NET developers had to learn new concepts (for instance,
isual FoxPro 9.0 is fully compatible with pervious versions of Visual FoxPro. With its local cursor engine, tight coupling between language and data, and powerful features, Visual FoxPro 9.0 is
he integration of heterogeneous software systems often requires disparate clients to share data seamlessly in real time. Two technologies that have eased this data flow are XML and Web services,
Instant messaging represents a medium via which messaging partners can interact in a synchronous fashion. Correspondence can occur in a near “instant” manner. Chances are the majority of workgroups in
he hype during the mid-to-late 1990’s over Java’s utility to run swarms of autonomous applets was greatly exaggerated. This early enthusiasm (and marketing) for Java as a language with which

here are incredible improvements in the Visual FoxPro 9 reporting system. Of several aspects, I’ll discuss just one in this article: the ability to extend the behavior of the runtime
ierDeveloper is an Object-to-Relational (O/R) mapping tool that integrates with Visual Studio versions 2002 and higher. TierDeveloper maps Relational Database Management System (RDBMS) tables to .NET objects (VB.NET and C#),

To shutdown Windows, just type the following code: Shell “shutdown -s -t 00” To restart windows: Shell “shutdown -r -t 00” Here’s the key: -s means shutdown. -r means restart.
In Visual Studio, when you select an item on a form you’re building, the Property Grid appears and lets you set various properties (e.g. background color, width, height, text color,
Many of the STL algorithms have two versions, with one version taking one less parameter than what the second version takes. The one with lesser parameters implies its default logic
You cannot change the value of a nodes checkbox in the event treeview_NodeCheck as explained in this tip. Besides that, the event doesn’t fire at all when clicking a nodes
hy do we need to model software? After all, aren’t the acts of coding and refactoring of that code enough? That depends on what is meant by enough! You could
For persisting Java objects in a file, use java.io.ObjectOutputStream. ObjectOutputStream writes primitive data types or Java objects. Persistent storage can be accomplished by using a file for the stream. Only
