I will also be heading to SgDotNet Usergroup Meeting tomorrow to spread the event to the .NET users (in fact, the backend of the TAC registration runs on asp.net).
For those who wish to meet the organizers and the usergroup, learn about BlazeDS and Gaia Framework, feel free to join us at Yahoo! next week by RSVP here. There are just a few seats left at the time of this posting so do reserve one now.
Chain Events in Cairngorm allow you to chain up a series of Caingorm Events. This is especially useful when you are using a series of webservices and you need the results from the preceding one to execute the next one
Another example will be you need to execute a command that requires a prerequisite, such as authentication. You can use the Chain Event to execute the next command after authentication. It makes your code structured and easier to manage altogether
5 mins Flex video:
In this video, we use Seesmic API to show how we can search for a username existance in Seesmic, and if it exist, we use the result to get his/her videos.
SuperImage from Quieting Scheming is a must use and an excellent replacement for the Image component for List Component in Flex. If you have tried to develop mashup that tap into Flickr / YouTube / any type of API that load into thumbnail and images, you will realize that if your List control scrolls, the image will flicker very badly. This is because the image is not cached internally and thus this impact very badly on the performance as well as to the scrolling. My previous ’solution’ is to make sure that the user do not get the chance to scroll, and thus, only fetching a pre-setted number of results. This problem is solved by the Super Image, which caches the images internally.
If you are facing the same problem, download SuperImage now and try it on your Flex application. You will be surprised!
AsWing is a set of UI components for Actionscript 3.0. Like Flex, it has its own series of components like VBox, Buttons, etc, and are skinnable with customizable look and feel. The good thing about AsWing is that you do not need to have a Flex project to use it. You can build it upon a pure AS3 project.
Since it is based from its Java sibling Swing, Java developers will find its API very familiar.

A short snippet to convert a uicomponent into base64 data which you can send to your database. I need to convert images into base64 data for AirTalkr as Openfire requires the avatar to be set in base64 format. Here is the snippet:
import flash.display.BitmapData;
import com.adobe.images.JPGEncoder;
import mx.utils.Base64Encoder;
import flash.utils.ByteArray;
privatestatic const QUALITY:Number =80function getBase64FromComponent(photo:UIComponent) :String{var data1:BitmapData = new BitmapData(photo.width, photo.height); data1.draw(photo);
var en:JPGEncoder = new JPGEncoder(QUALITY);
var bArray:ByteArray= en.encode(data1);
var encoder:Base64Encoder = new Base64Encoder();
encoder.encodeBytes(bArray, 0, bArray.length);
var base64data:String = encoder.flush();
return base64data;
}
PS: I am not sure if there is a shorter way to do the above, like using base64Encoder directly. If there is, and I am doing extra stuff, do let me know!
