How to use Local XML for HTTPSERVICE

As we know that used for remote server application. But in case we have local XML file then how we can fetch recored from XML using
1. First create new project in Adobe Flex Builder 3.
File -> New -> Flext Project give some name (say Binod_ShareTrading) and click on Finish.
2. Paste you local XML into src folder (say addressbookdata.xml)



3. Right click on Binod_ShareTrading project and click on properties -> Flex Compiler and come to Additional compiler arguments: and put this info
-locale en_US -use-network=false and click on Apply and OK.
Now it will inform to httpserice that do not look on internet for the given XML file.

4. Now start your code in Binod_ShareTrading.mxml (May be different in your case)

How to give some effect to your component in FLEX using ACTIONSCRIPT

Suppose you have some component in your FLEX application and you want to give effect like during visible=flase it should show fade during visible=true it should rotate.
For example, if you have one datagrid say mygrid

< id="mygrid" x="485" y="119" width="600" dataprovider="{employees.contact}" visible="false">

< mx:columns >
< headertext="UserName " datafield="userName">
< headertext="Location" datafield="location">
< headertext="Email" datafield="email">
< /mx:columns >
< /mx:DataGrid >

and you want to put the effect then you have write one method

private function init():void {
mygrid.setStyle("showEffect", rotate);
mygrid.setStyle("hideEffect", fade);
}

and obiviously this method should run during application start time, so you have to add this method name with <mx:Application ...... /> like this
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init();">
Put these below code outside from < / mx:script >

<mx:Fade id="fade"/>

<mx:Fade id="fadeOut" duration="4000" alphaFrom="1.0" alphaTo="0.0"/>
<mx:Rotate id="rotate"
angleFrom="-180"
angleTo="0"
easingFunction="Elastic.easeInOut"
duration="2000" />

You can also set Face class directly in the function without <mx:Fade id="fade"/>

private function init():void {
// Fade effect
fade = new Fade();
// Rotate effect
rotate = new Rotate();
rotate.angleFrom = -180;
rotate.angleTo = 0;
rotate.easingFunction = Elastic.easeInOut;
rotate.duration = 2000;
mygrid.setStyle("showEffect", rotate);
mygrid.setStyle("hideEffect", fade);
}


That it !!!!!!!!!!!!!!!!!!!!!!!! :)
