Flex: working with MovieClips
June 16th, 2008
You do not do everything with Flex components, especially if you develop games or cool interfaces. You often need to load SWF files and use the MovieClips inside them. A previous article talks about Instantiating and displaying MovieClips from loaded SWF. Here are a few considerations when loading MovieClips into Flex: If you embed a […]
codeFest 2.1 Conclusion
May 19th, 2008
The codeFest is now over. It went really well. We had about 20 developers yesterday. It was really productive for most people. Some learned a lot. The event was beneficial to the community. With Yann Larrivée and Louis-Philippe Huberdeau, I was able to make much progress on the PHP Quebec website (jobs section). The new […]
.htaccess on Leopard
April 28th, 2008
After moving my databases and websites to a new Mac with Leopard, none of the websites were working. It was as if mod_rewrite was not working. First, I noticed that the .htaccess files were all ignored. I checked the Apache configuration file in MAMP, and everything seemed fine. After over an hour of going through […]
Runtime Sharing problems solved for good!
March 26th, 2008
I stayed at work until 8:00 pm today because I could not figure out why I was getting a #1065 Reference Error when using Runtime Sharing. The scenario A main ActionScript application loads multiple swf files (screens). These swf import various symbols from a central swf (global_asset_library). When I load the first screen, I can […]
Data Binding expressions
March 8th, 2008
In MXML, you may use expressions as a source of data binding. The Label will only be displayed if the person is 18 or older. Did you try a more complex expression? Ah ha! You get a compiler error. Why? Because you’re inside MXML and the & character is special. […]
[Bindable] public override
March 7th, 2008
I stumbled upon a compiler error when overriding a setter function with the Bindable metadata tag: “overriding a function that is not marked for override” The answer is short and simple: use –[Bindable] public override– instead of –[Bindable] override public– It may sound silly but the override actually has to come second in order for […]
Instantiating and displaying MovieClips from loaded SWF

So you want to dynamically load a .swf, instantiate it and add to to a SWFLoader control. […]
AS3 data binding and component states
February 28th, 2008
If you ever developed a complex data-driven application, you probably stumbled upon the data binding nightmare. Altough a great feature in Flex (a central one in my opinion), it lacks a bit of control. I needed a form with multiple states depending on the flavor of the edited object. This way, I could have common […]
AIR Prerelease Tour
February 8th, 2008
I attended a presentation on Flex and AIR yesterday. Mike Potter was unable to come and was replaced by LordAlex Leon. The presentation began with a long description of Adobe applications and their integration, but an hour later finally reached AIR. The part about AIR was quite short and did not teach me anything new. […]
Sending headers
February 7th, 2008
There are many reasons to send headers in the middle of you PHP script. Sometimes you want to redirect the user based on some computed information or display different content types (mime-type). Have you ever had a problem with PHP complaining about “output already sent”? To solve this problem, there is a workaround with ob_start/ob_flush. […]
