Custom AIR updater interface using ApplicationUpdater
To tell you the truth, I never gave the ApplicationUpdaterUI much thought in terms of memory use before this post. I just thought it was a great way to add a complete update system to your AIR applications. I had not thought it could be so memory intensive until a recent conversation with [...]
Garbage collection and styles
I read a really great post in my endless search for better garbage collection in AIR and Flex. Bernd Bindreiter of firstrow RIA posted a 5-part series on garbage collection and one of them involves removing skins from Button controls in order to have them garbage collected properly. In his post he [...]
AIR :: TextField bug when resetting HTML text.
I ran into a really strange issue that only occurs within AIR applications (AIR 1.5.1/1.5.2). When I create a TextField control, set it's style, and then assign it HTML text it appears fine. However, if I wish to reset that TextField content and the original content has links, the entire replaced content becomes one HTML link. I think the issue can be better explained with some images and some code samples.

With Flex truncating text within a Label control is easily done by setting the property “truncateToFit” to true. This parameter doesn’t do much when using the Text or TextArea controls in Flex. To truncate text in these controls you would have to build your own function to count characters and add the [...]
Garbage Collection and Event Listeners

My concerns have centered around garbage collection and event listeners, specifically how you clean up event listeners to allow Garbage Collection (GC) to clean up objects. Most DisplayObjects implement the EventDispatcher class that allows it to broadcast events. [...]

I was calling an RESTful service that returns XML and using the built-in Flex HTTPService with either POST/GET as the method for the request. Most [...]

Smooth Scrolling HorizontalList
This example is based on Alex Harui’s Smooth Scrolling List. It just changes the code to work with the HorizontalList control rather than the List control. The SmoothHorizontalScrollingList class extends the HorizontalList control adding the needed functionality to allow smooth scrolling:
