Is it possible to readUTFBytes from a remote file without prompting the user with the download screen?
Thank you.
Sure, use URLLoader.
private var loader:URLLoader;
private var req:URLRequest;
private function init():void {
loader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.BINARY;
req = new URLRequest("..."); //url
loader.addEventListener(Event.COMPLETE, onComplete);
loader.load(req);
}
private function onComplete(event:Event):void {
ByteArray(loader.data).readUTFBytes(100);
}

I am reading in an XML file that is shown in the attached image. I'm reading it in using URLRequest, which works properly. The next thing I'd like to do is to populate an arraylist with all of the "project" nodes. I'm converting the XML to an array, but the source is showing the project as being in the [0] node and the arraylist's length is 1.
What's the proper way to do this so I can loop through all the projects in the arraylist?
private var xmlParameters:XML
private var xmlStoryMap:XMLList;
protected function application1_creationCompleteHandler(event:FlexEvent):void
{
var params:Object;
var xmlLoader:URLLoader = new URLLoader();
xmlLoader.addEventListener(Event.COMPLETE, xmlloader_onComplete_Handler);
xmlLoader.addEventListener(IOErrorEvent.IO_ERROR,IOError_handler);
xmlLoader.load(new URLRequest("myXML.xml"));
}
protected function xmlloader_onComplete_Handler(event:Event):void
{
var loader:URLLoader = URLLoader(event.target)
xmlParameters = new XML(loader.data);
xmlStoryMap = xmlParameters.projects;
initializeMap();
}
protected function initializeMap():void
{
var testlist:ArrayList = new ArrayList();
testlist.source = convertXMLtoArray(xmlStoryMap.project);
}
private function convertXMLtoArray(file:String):Array
{
var xml:XMLDocument = new XMLDocument(file);
var decoder:SimpleXMLDecoder = new SimpleXMLDecoder;
var data:Object = decoder.decodeXML(xml);
var array:Array = ArrayUtil.toArray(data);
return array;
}
If you don't want to have a loop issue, use this instead
protected function xmlloader_onComplete_Handler(event:Event):void
{
var loader:URLLoader = URLLoader(event.target)
var xmlString:String = loader.data;
initializeMap(xmlString);
}
protected function initializeMap(xmlString:String):void
{
var testlist:ArrayList = new ArrayList();
testlist.source = convertXMLtoArray(xmlString);
}
private function convertXMLtoArray(xmlString:String):Array
{
var xmlDoc:XMLDocument = new XMLDocument(xmlString);
var decoder:SimpleXMLDecoder = new SimpleXMLDecoder();
var data:Object = decoder.decodeXML(xmlDoc);
return ArrayUtil.toArray(data.storymap.projects.project);
}
For looping through the projects,
for each(var projectXML:XML in xmlParameters.projects.project)
{
// Do operation
}
I m using flex4.6 and i wanted to run a .bat file from ma air application, is there any help ?
You can use NativeProcess class.

Try this

Before run applications (Projectname-app.xml) check supportedProfiles tag

I have problems getting my flex code to work, below is my code I try to netstream a webcam and receive it and use 2 functions for that. Any flex guru can help me fix these functions?
function onNetConnectionPublish():void {
StatusMessage("onNetConnectionPublish called");
ncNetStream = new NetStream(nc, NetStream.DIRECT_CONNECTIONS);
ncNetStream.addEventListener(NetStatusEvent.NET_STATUS, sendNetStreamHandler);
ncNetStream.publish("media");
ncNetStream.attachAudio(Microphone.getMicrophone());
ncNetStream.attachCamera(Camera.getCamera());
}
and:
function connectToRemote(remoteId:String) {
StatusMessage("connectToRemote(" + remoteId + ")");
ncNetStream = new NetStream(nc, remoteId);
ncNetStream.addEventListener(NetStatusEvent.NET_STATUS, receiveNetStreamHandler);
ncNetStream.play("media");
}
display video:

private function Publisher():void{
var camera1:Camera = Camera.getCamera();

video.attachCamera(camera1);
VideoDisplay1.addChild(video);
camera1.addEventListener(ActivityEvent.ACTIVITY, camera_activity);
camera1.addEventListener(StatusEvent.STATUS, camera_status);
}
var nc:NetConnection = new NetConnection();
nc.connect("rtmp://your/stream/url");

I would like to load a an image from an external domain and I have the below so far:
private function get_coverArt(coverArtID:String):void
{
var requestString:String = "/rest/getCoverArt.view?v=1.5.0&c=AirSub&id=" + coverArtID;
var requestURL:String = subServerURL + requestString;
myCoverArtLoader = new URLLoader();
var myRequest:URLRequest = new URLRequest();
var authHeader:URLRequestHeader = new URLRequestHeader();
authHeader.name = 'Authorization';
authHeader.value = 'Basic ' + credentials;
myRequest.requestHeaders.push(authHeader);
myRequest.url = requestURL;
myRequest.method = URLRequestMethod.GET;
myCoverArtLoader.dataFormat = URLLoaderDataFormat.BINARY;
myCoverArtLoader.addEventListener(Event.COMPLETE, set_coverArt);
myCoverArtLoader.load(myRequest);
}
private function set_coverArt(evt:Event) : void {
coverArtImg = new Image();
var loader:Loader = new Loader();
loader.loadBytes(myCoverArtLoader.data);
coverArtImg.source = loader;
}
This does not seem to work - any help?
Thanks!
Try setting the source directly like so:
private function set_coverArt(evt:Event) : void {
coverArtImg = new Image();
coverArtImg.source = myCoverArtLoader.data;
}
Also, check your authentication, here's a question I answered regarding the auth :

following is my code for loading one video using FileReference class and it works fine

the sender.mxml code is following which plays the video on the stage
private function init() : void {

fileLoader.addEventListener(Event.COMPLETE, fileLoaded);
fileShare = new P2PFileShare();
fileShare.addEventListener(StatusEvent.STATUS,

if (fileShare.connected) {
fileShare.p2pSharedObject = fileLoader.p2pSharedObject;
fileShare.p2pSharedObject.lastIndexBegin = 0;
fileShare.p2pSharedObject.lastIndexEnd = fileShare.p2pSharedObject.packetLength-1;
fileShare.updateHaveObjects();
}
setupVideo();
// PLAY
ns.play(null);
ns.appendBytesAction(NetStreamAppendBytesAction.RESET_BEGIN);
ns.appendBytes(fileLoader.p2pSharedObject.data);
video.attachNetStream(ns);
}
private function setupVideo():void{
var nc:NetConnection = new NetConnection();
nc.connect(null);
ns = new NetStream(nc);
ns.client = this;
ns.addEventListener(NetStatusEvent.NET_STATUS,
function(event:NetStatusEvent):void{
writeText("stream: "+event.info.code);
});
video = new Video();
videoComp = new UIComponent();
videoComp.addChild(video);
this.addElement(videoComp);
}
then after this, the file.name and file.size goes to mxml page and the video is displayed on stage with name and file size
but the samething i want to do with FileReferenceList class, i am solving this problem from last 2 weeks but cant ,,, plz guide me ,,, i google so many times but no specific answer

You can use the fileList property of the FileReferenceList class to access the files that where selected. Then load() each FileReference in the list separately:
private var list:FileReferenceList;
public function browseFileSystem():void {
list = new FileReferenceList();
list.addEventListener(Event.SELECT, selectHandler);
list.browse();
}
protected function selectHandler(event:Event):void {
for each ( var file:FileReference in list.fileList) {
file.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
file.addEventListener(ProgressEvent.PROGRESS, progressHandler);
file.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
file.addEventListener(Event.COMPLETE, completeHandler);
writeText(file.name+" | "+file.size);
file.load();
}
}
