This is a dream come true.
To run an EXE from AIR, do the following steps:
Step 1:
Install the exe from this Link
Step 2:
Import Flex Project samples, from install dir ex: C:\Program Files\FluorineFx Aperture\Samples
Step 3:
Copy *.dll files (apimaging.dll,apoutlook.dll,apSystem.dll,fluorinepp.dll and msi.dll) to your Flex src directory
Step 4:
Copy your ‘-app.xml’ to ‘C:\Program Files\FluorineFx Aperture\Debug’ location of install dir for debugging or just pack the AIR

A Quick tip, was stuck today to load an local image / swf inside AIR at MAC OS.
The below is the solution:

var filenotion:String =”;
if(Capabilities.os.search(“Mac”) >= 0) filenotion = “file://”;
Image.source= filenotion +imgFileURI;

How to do :

1 ) To create resource bundles for different languages and then use the ResourceManager class provided by the Flex API to get the resources.
Just changing the locale of the resource manager will reflect changes in the entire application with the values from the new locale’s resource bundle.

How to Create Locale :

For example if I want to support two locales (en_US and fr_FR) in your application and I my parent folder is named as “Locales”, then I might have following folders. As en_US ,fr_FR

It will be like this :
Locales/en_US , Locales/fr_FR

Steps to do before make the Bundle

Part 1 : SDK

Create folder
1 D:\Program Files\Adobe\Flex Builder 3\sdks\3.2.0\frameworks\projects\framework\bundles \fr_FR
2 D:\Program Files\Adobe\Flex Builder 3\sdks\3.2.0\frameworks\projects\framework\bundles\fr_FR \src

Download and paste
3.http://opensource.adobe.com/svn/opensource/flex/sdk/trunk/frameworks/projects/framework/bundles/fr_FR inside step 2

Create folder :
4 D:\Program Files\Adobe\Flex Builder 3\sdks\3.2.0\frameworks\locale \fr_FR

Execute
5. D:\Program Files\Adobe\Flex Builder 3\sdks\3.2.0

bin\compc -locale=fr_FR -source-path+=frameworks/projects/framework/bundles/fr_FR/src -include-resource-bundles=collections,containers,controls,core,effects,formatters,logging,SharedResources,skins,states,styles,utils,validators -output=frameworks/locale/fr_FR/framework_rb.swc

Part 2 : Project

1. Set System PATH
D:\Program Files\Adobe\Flex Builder 3\sdks\3.2.0\bin
2. create required properties file mainBundle.properties
3. keep that file inside a folder with your locale name ‘fr_FR
4.execute from root path
mxmlc -locale=fr_FR -source-path={locale} -include-resource-bundles=mainBundle,collections,containers,controls,core,effects,skins,styles -output=src/Resources_fr_FR.swf

mxmlc -locale=en_US -source-path={locale} -include-resource-bundles=mainBundle,collections,containers,controls,core,effects,skins,styles -output=src/Resources_en_US.swf

After that place that swf file your Project

Locale/en_US :
Inside we need create the file name like “mainBundle.properties” inside that we need to create like that

welcome_title_text=Welcome,
form_first_name_text=First Name
form_second_name_text=Last Name
form_gender_text=Gender
form_gender_list_male_text=Male
form_gender_list_female_text=Female

Locale/fr_FR :
Inside we need create the file name like “mainBundle.properties” inside that we need to create like that

welcome_title_text=Bienvenue ,
form_first_name_text=Prénom
form_second_name_text=Nom de famille
form_gender_text=Sexe
form_gender_list_male_text=Mâle
form_gender_list_female_text=Femelle

Adding Locales to your Projects
Add the locale to the compiler options.
-locale=en_US,fr_FR

This link, claims to have compiled swc files for most languages : Babel

This Post was my overdue subject, I wanted to help with a sample Application using Cairngorm, Spring BlazeDS Integration & Generic DAO.

This might be a heavy subject as it deals with many subjects:

• Cairngorm with UM Extensions , from Universal Mind
• Spring BlazeDS Integration, from Spring Source
• Spring, from Spring Source
• Hibernate
• Generic DAO, from IBM.
• Spring Security 2.0, using MySQL.

The Source is available at the link: cairnspring

How to use the source effectively?
it is simple, steps below:

1. Download, Source and Libs
2. Unzip both and import “CairnSpring”, to your Eclipse
3. Paste the lib files to “CairnSpring\WebContent\WEB-INF\lib” folder
4. Import the “db.sql” into your MySQL Db, (change mysql port to 3036, else can be configured to default in “CairnSpring\WebContent\WEB-INF\config\jdbc.properties” file)
5. In Eclipse, Window -> Preferences -> Web and XML -> XML Catalog -> Add User Specified Entries with below values
   Location : CairnSpring/WebContent/WEB-INF/config/spring-flex-1.0.xsd
   KeyType : Namespace Name
   Key : http://www.springframework.org/schema/flex/spring-flex-1.0.xsd
6. Start the Tomcat Server with CairnSpring instance (the server host and port can be configured in file “CairnSpring\flex_src\Server.properties”)

The code file contains functions for managing SQL Lite Table and Database

Save the below code as a Class file and refer the class name as

{
super();
// Set the download label.
downloadingLabel=”Downloading…”
// Set the initialization label.

// Override to return true so progress bar appears during download.
override protected function showDisplayForDownloading(

Today, i faced a weird problem of fileReference.load() not working in AIR. Even, in the latest 3.3 SDK. To resolve that, you have to install Flex Builder Update. Then, modify your App.xml into air version 1.5. As, to get the benefits of latest AIR Version.

Otherwise, in AIR: Code gets compiled but when we select a file from system, it throws a error.

Utility functions to find First Day of a month, Relative Date information like “Today”, “Yesterday”

public static function getFirstDayofMonth(fullyear:uint,month:uint):uint
{
var tmp:Date = new Date(fullyear,month,1);
return tmp.getDay();
}

public static function isLeapYear( fullyear:uint ):Boolean
{
var flag:Boolean = false;
if(((fullyear%4==0) && (fullyear%100!=0)) || (fullyear%400==0)) flag = true;
return flag;
}

public static function getWeekName( index:uint , type:uint=0 ):String
{
var week:Array;
if(type==0) week = ["SUNDAY","MONDAY","TUSEDAY","WEDNESDAY","THURSDAY","FRIDAY","SATURDAY"];
else if(type==1) week = ["SUN","MON","TUE","WED","THU","FRI","SAT"];
else week = ["Sun","Mon","Tue","Wed","Thu","Fri","Sat"];
return week[index];
}

public static function getMonthName( index:uint , type:uint=0 ):String

The below custom functions might be of use where you don’t want to use currency formatter or numeric Formatter of AS3

 
public function currencyFormat( number:Number ):String {
var words:Array = String( number ).split( “” ).reverse(); 
  var results:Array = new Array();
 var l:int = words.length;
  for ( var i:int = 0; i < l; i++ ) {
   results.push( words[i] );
   if ( i % 3 == 2 ) {
     results.push( “,” );
   }
   }
   return results.reverse().join( “” );
}

public function prefixZero( number:Number, figure:int ):String {
   var str:String = String( number );
   for ( var i:int = 0; i < figure; i++ ) {
     str = “0″ + str;
   }
   return str.substr( str.length – figure, str.length );
}

The Below code demonstrates the conversion of ByteArray to BitmapData. In the below case, SWF is loaded and converted into BitmapData

private function swfLoad_complete(evt:Event):void {
byteArrayToBitmapData(swf.content.loaderInfo.bytes);
}
private function byteArrayToBitmapData(ba:ByteArray):void {
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, getBitmapData);
loader.loadBytes(ba);
}
private function getBitmapData(e:Event):void {
var content:* = loader.content;
var BMPData:BitmapData = new BitmapData(content.width,content.height);
var UIMatrix:Matrix = new Matrix();
BMPData.draw(content, UIMatrix);
}

The code below demonstrates the data type conversions among basic DataTypes used most in Flex. The ‘init()’ method does to and from conversion for ArrayCollection to XML and XML to ArrayCollection

To Select a Static Text in Flash, as like mentioned in LiveDocs.
It doesn’t work, its mentioned in the below bug entry [Link].

The work around for that is to embed the fonts of the text in your flash movie.

I came across the efflex.org. Its so amazing.. someone took effort to make such library.. I compiled a zip with required Lib elements on this link efflex.
