How to create an exit button in a full screen swf file? - actionscript-3

Question

I'm currently making my thesis in Flash. Does anyone know how to put a warning before quitting the app? Like when a user clicks the "X" button, a "Are you sure you want to quit? Yes? No?" will pop up? Also, it is on a f
So far, my code for the Exit button is
addEventListener(MouseEvent.CLICK, CloseApp);
function CloseApp(e:MouseEvent) {
fscommand("quit");
}
hence, when click, it automatically closes the app. Thank you very much!

The following piece of code illustrates how to achieve this result using Adobe AIR & Flex SDK.
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
closing="onClosingMainWindow(event)">
<fx:Script>
<![CDATA[
import mx.controls.Alert;
import mx.events.CloseEvent;
protected function onClosingMainWindow(event:Event):void
{
event.preventDefault();
Alert.show('Are you sure?','',Alert.YES|Alert.NO,null,function(event:CloseEvent):void{
if(event.detail == Alert.YES)
nativeApplication.exit();
});
}
]]>
</fx:Script>
</s:WindowedApplication>
And the same result using Adobe AIR in Flash Pro. (Pure AS3)
import flash.desktop.NativeApplication;
import flash.events.Event;
//activeWindow will be null until the frame will not be constructed.
stage.addEventListener(Event.FRAME_CONSTRUCTED, onFrameConstructed);
function onFrameConstructed(event:Event){
stage.removeEventListener(Event.FRAME_CONSTRUCTED, onFrameConstructed);
NativeApplication.nativeApplication.activeWindow.addEventListener(Event.CLOSING, onClosingMainWindow);
}
function onClosingMainWindow(event:Event):void
{
event.preventDefault();
//The following code will close the app.
//NativeApplication.nativeApplication.exit();
}

import flash.desktop.NativeApplication;
import flash.events.Event;
addEventListener(MouseEvent.CLICK, CloseApp);
function CloseApp(e:MouseEvent) {
stage.nativeWindow.close();
}
should do the job
