Here is an example that illustrate how you can upload an image or a swf in your Flash ActionScript 3.0 project .

ActionScript 3.0 code:

// create the MovieClip that will hold the object loaded
var _mc:MovieClip = new MovieClip();
addChild(_mc);

// create the URLRequest with the path to the object you want to load
var request:URLRequest = new URLRequest("image.jpg");
var loader = new Loader(); // create the Loader object
loader.load(request);

loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onLoadProgress);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadComplete);
loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, onLoadError);

// call this function when the object is loading
function onLoadProgress(event:ProgressEvent):void
{
    // display the percentage loaded
    trace(int(event.bytesLoaded/event.bytesTotal*100)+"%");
    // display the bytes loaded and the total number of bytes
    trace(event.bytesLoaded+":"+event.bytesTotal);
}

// call this function when the object is loaded
function onLoadComplete(event:Event):void
{
// duplicate and resize a loaded image (doesn't work for swf)
// ----->
    var objectDuplicate:Bitmap = new Bitmap(loader.content.bitmapData.clone());
    objectDuplicate.width = 100;
    objectDuplicate.height = 100;
    objectDuplicate.smoothing = true;
    _mc.addChild(objectDuplicate);
// ----->

    _mc.addChild(loader); // attach object to MovieClip
}

// call this function if the path to the object that you want to load is not valid
function onLoadError(event:Event):void 
{
        trace("Error! The URL was not found.");
}

This is very useful when you try to create a “liquid” flash application.

ActionScript 3.0 code:

//The next 2 lines are not mandatory. 
//Use them if you whant to keep the original sizes.
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.align = StageAlign.TOP_LEFT; // Other values: 
//TOP, BOTTOM, LEFT, RIGHT, TOP_RIGHT
// BOTTOM_LEFT, BOTTOM_RIGHT 

stage.addEventListener(Event.RESIZE, resizeHandler);

function resizeHandler(event:Event):void 
{
        trace(stage.stageWidth);
        trace(stage.stageHeight);
        trace("An event has been triggered.");
}

Here is an example on how to get data from XML file using ActionScript 3.0.

XML file example:

<?xml version="1.0" encoding="utf-8"?>
<Data>
    <Title font="Arial">
        XML Example
    </Title>
    <HTML_Example>
        <![CDATA[You can add html text here.]]>
    </HTML_Example>
    <List>

        <URL>http://www.mariuscristiandonea.com</URL>
    </List>
</Data>

ActionScript 3.0 code:

var XMLLoader:URLLoader;
var XMLPath:URLRequest;
var XMLDoc:XMLDocument = new XMLDocument();
XMLDoc.ignoreWhite = true;

XMLPath = new URLRequest("test.xml");
XMLLoader = new URLLoader(XMLPath);
// Call extractXMLFileData function if the XML file does load.
XMLLoader.addEventListener("complete", extractXMLFileData);
// Call errorXMLFileData function if the XML file didn't load.
XMLLoader.addEventListener("ioError", errorXMLFileData);

// This function parse the data from the XML file, if it is loaded.
function extractXMLFileData(event:Event):void
{
    var XMLData:XML = XML(XMLLoader.data);
    XMLDoc.parseXML(XMLData.toXMLString());
// Define the first node.
    var DataNode:XMLNode = XMLDoc.firstChild; 

// Read a node attribute.
    trace(DataNode.firstChild.attributes.font);
// Read a node value.
    trace(DataNode.firstChild.firstChild.nodeValue);
// Here we read the node value that contains the HTML text.
    trace(DataNode.childNodes[1].firstChild.nodeValue); 

// In the next "for" we read all the URL nodes.
    for (var currentNode = DataNode.childNodes[2].firstChild;
currentNode != null; currentNode=currentNode.nextSibling)
    {
// If the name of the node is "URL" then we read the value from it.
        if (currentNode.nodeName == "URL")
        {
            trace(currentNode.firstChild.nodeValue);
        }
    }
}

// This function takes action if the XML file didn't load.
function errorXMLFileData(event:Event):void
{
    trace("Error! The XML file didn't load!");
}

This is a function that changes the color of a video given as a parameter in a new color given as parameter as well.

ActionScript 3.0 code:

import flash.geom.ColorTransform; // import ColorTransform class

function setColor(_mc:MovieClip, color):void
{
    var newColor:ColorTransform = _mc.transform.colorTransform;
    newColor.color = color;
    _mc.transform.colorTransform = newColor;
}

setColor(bigBtn.icon.bg, 0xff0000); //call the function
