For over a decade now, we have been trained to use the 'back' and 'forward' buttons in our Web browser to review or backtrack previously viewed content. We are trained to the point that there are even keyboard shortcuts. Unfortunately, this can be a problem when browsing Flex applicati...

This article is about creating a Flex tree control that uses a component hierarchy as the data provider. As with most of my Flex development, after struggling for days and then finally getting something to work, I later find out that there is a much easier way to do it that none of my ...

This article is based on a presentation that I made at the Adobe Flex seminar in August 2006 (www.flexseminar.com/), after which the master of ceremonies Jeremy Geelan asked me to explain how to make great mapping mashups using Adobe Flex.

Ten years ago I've been doing PowerBuilder and my mentality was different: first, I was the best friend of business users, and second I did not really worry about what's under the hood. I could do stuff quickly, or using the modern jargon, I was an

Here's the assignment: write a Flex application that can run against different servers (dev, uat, prod) without the need to recompile the SWF file. It does not take a rocket scientist to figure out that the URL of the server should be passed to SWF as a parameter, and we’ll do this by...

Flash Player 9 enters pre-Alpha stage on Linux. Adobe marketing needs to work harder.

We are about to enter a new era, when plain looking Web applications will gradually be replaced with RIA delivered over the Web that can actually land on the PC and work in a disconnected mode as well. How this will affect the evolution of Business Intelligence (BI) applications?

You read the blogs, see a couple of articles, and hear all the buzz about Flex 2 and how it can really transform how your users can fluidly interact with information and the business in an exciting and efficient new way.

In Java, if you've created an object from a particular class, you can use only properties and methods that were defined in this class. This is not the case in ActionScript 3. This is one of the examples of unusual (from the OOP perspective) programming techniques.

Traditional application development processes make it challenging to meet the time and budget constraints facing businesses today. Going from the requirements gathering phase to writing up design documents to delivering applications can take many months-which is often too long for exec...

We've all seen Google finance, and the great job that it does at mixing HTML content with Flash content, as seen on company stock quotes. Google has done a great job at using Flash where it makes the most sense, in the graphs for company quotes, with HTML where it makes sense (linking ...

There comes a day when we all need an application in multiple languages. Eso es la verdad. In Flex, the solution to this problem is resource bundles. In this article, I'll describe the basic use of resource bundles and create a small example in Flex Builder. I'll also suggest some ...

Each of our students comes with different understanding of how to program in Flex according to their 'legacy' background. So I'll tell you the story that might have happened in a real life, but first, let me remind you of an old Indian tale about seven blind men and an elephant. In sho...

While a large Flex application is loaded, the user may experience unpleasant delays, which can be used productively to logon to this application. Besides, it'll give the user perception that your application loads faster.

This sample application shows the data exchange between Adobe Flex and Microsoft Excel

Flash components are badly written; there are many undocumented bugs that you would never overcome, e.g., try adding a combobox to an accordion pane, or a menu inside of a scrollpane. The most awful truth about Flash components is that they are badly integrated with one another and put...

Can you put Flash Player's pretty face on your Web application written in Java/.Net/Python/PHP et al? Yes. Can you do it for free? Yes.

There are quite a few developers that a) become impatient if the build takes more then 5 seconds and b) concerned that their application will be delivered to the user with similar attention span that could walk away in 10 seconds or less - regardles of the artwork in the progress mete...

Adobe Flex Builder has many convenient keyboard commands and hints that make your programming faster. But this is a list of Flex Builder shortcuts that I use on a regular basis

Flexstore is a traditional Shopping Cart application. In this tutorial, we create two modules: The administration module is an internal application used to maintain the product database. You use the administration module to create, update, and delete products. The store module is a cus...

The JBoss Mail Server (JBMS) has been recently re-branded for its upcoming 1.0 release as 'JBoss Collaboration Server.' The web-based mail client component of the whole collaboration server package, says JBoss's Andy Oliver, is 'spellbinding.' The JBMS team used Flex 2.0 from Adobe.

Some people take the dog for a walk, other go play a round of golf. Not Christophe Coenraets. His idea of a good time is to illustrate Flex and JMS integration by extending a simple 'realtime feed' application that he built a while back! Web Developer's & Designer's Journal is proud to...

A typical Java developer knows that when you need to develop a GUI for a Java application, Swing is the tool. Eclipse SWT also has a number of followers, but the majority of people use Java Swing. For the past 10 years, it was a given that Swing development wouldn't be easy; you have t...

'One of the questions that comes up a lot when we're talking about Flex with web developers is 'How does this relate to AJAX?'' writes Ely Greenfield, a long time developer at Macromedia/now Adobe on the engineering team behind the design and development of the Flex SDK.

Communication Server (FCS) together provide an amazing toolbox that will undoubtedly provide inspiration to thousands of developers and projects. Unfortunately, without concrete examples and guidelines for good practices on their integration, we spent many hours on tiny issues that, wi...

Since a Rich Internet Application (RIA) is not a stateless client, you typically have a lot of data in the client, especially when you load dynamically over time. Often, while developing Flex applications, you might need to peek at data structures during runtime - this is where my util...

In the early days of Flex beta (Royale), we were shown a fantastic new product that would allow folks to write rich User Interface (UI) designs via an XML style solution, named MXML.
