In my tablet app I download files from the server and I try to save these files to my application storage directory. Then I get an error which says:
Error #2044: Unhandled IOErrorEvent:. text=Error #2038: File I/O Error.
It is occuring on this line:
var fileStream:FileStream = new FileStream();
Maybe some files are corrupted on the server but I can influence this. I tried to catch the error, but this isn't working. What do I do wrong?
The complete code
try {
var file:File = File.desktopDirectory.resolvePath(_path);
var fileStream:FileStream = new FileStream();
fileStream.openAsync(file, FileMode.WRITE);
var fileData:ByteArray = new ByteArray();
_urlStream.readBytes(fileData, 0, _urlStream.bytesAvailable);
fileStream.writeBytes(fileData,0,fileData.length);
fileStream.close();
} catch(error:Error) {
// do something
}

I'm working on an application and we are using Flash to add an interface. During the initialize the app loads in a config file with references to image paths. When I use the Loader and URLRequest classes to load those images the path is not working and it's causing issues. Based on everything I've researched my code should work. I have a trace that outputs "source/icons/default.png" which is the correct relative path for the external image and loading the image works, but I need to use a variable to set the image path. Setting the URLRequest with a variable, new URLRequest("source/icons/" + default.png);, causes it use a full file path that looks wrong and reports a 2035 error. Is there something that I'm doing wrong? I'm not sure what to do at this point. I've verified the file exists and I've verified the path of the file.
Trace Ouput:
source/icons/default.png
Error Output:
[CompanionStatus] Error occurred while loading bitmap
[CompanionStatus] 2035 : Error #2035: URL Not Found. URL: file:///C|/Users/devtrooper/Desktop/project/source/icons/default.png
It looks like flash is replacing the colon (:) near the drive letter with a pipe (|) and I'm not sure if that is the issue.
Here is my method for loading images:
private function getBitmapData(nameString:String, imagePath:String):void{
try{
var bitmapDataFunction:Function = addBitmapDataToDictionary(nameString);
var path:String = ICON_FOLDER_PATH + imagePath;
var loader:Loader = new Loader();
var urlRequest:URLRequest = new URLRequest("source/icons/" + imagePath);
trace("URLRequest.url " + urlRequest.url);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, bitmapDataFunction, false, 0, true);
loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, handleBitmapDataError, false, 0, true);
loader.load(urlRequest);
} catch (e:Error) {
log("Error occured while trying to load image data");
log(e.name + " : " + e.message);
}
}
you can use File method instead of urlRequest method like this:
var urlPath:String="";
var picFile:File = File.desktopDirectory.resolvePath("source/icons/default.png");//you can use applicationDirectory,applicationStorageDirectory,userDirectory,doumenntDirectory and ...
if (picFile.exists == true) {
urlPath = picFile.url;
}
I have an Adobe Air Application that would open an csv file on Mac. I am getting an error which I am not getting with the same app for Windows, so I am thinking something about file locations, etc is amiss. Here is the code:
var file: File = File.applicationStorageDirectory;
file = file.resolvePath("A&P plans");
file.addEventListener(FileListEvent.SELECT_MULTIPLE, filesSelected);
function filesSelected(event: FileListEvent): void {
//trace(event.files.length);
fileList = new Array();
fileNames = new Array();
for (var i: uint = 0; i < event.files.length; i++) {
fileList.push(event.files[i].nativePath);
trace("name of file loaded is ", event.files[i].name, "where :", event.files[i].nativePath);
}
}
var urlRequest: URLRequest = new URLRequest(fileList[0]);
function openCSVFile():void{
csv = new CSV(urlRequest);
csv.addEventListener(Event.COMPLETE,onComplete);
csv.addEventListener(IOErrorEvent.IO_ERROR, onErrorOpening);
function onComplete(event:Event):void{
trace("file open successful");
}
function onErrorOpening(event:IOErrorEvent):void{
trace ("error opening file");
}
}
The URLRequest trace shows the location where it should be, so the app knows where to look, and it does find the file. Here is the result of the trace :/Applications/myApp.app/Contents/Resources/A&P plans/majors/NationalLeague.csv. Yet, instead of the completeEvent showing the trace, the errorEvent is inovked. Any ideas where to look for the issue? The file does not have any weird characters in its name or anything. Tracing the error shows the following: Error #2032: Stream Error. Thanks
Quite possibly the ampersand and the space in 'A&P plans' might be troublesome.
Try removing/changing those.
There are images inside of folder names like Slide1.jpg,Slide2.jpg, until Slide20.jpg. But program doesn't know how many images inside of folder. I dont want to count them also.(lets say total number of images = 100). But when press nextBtn until Slide20.jpg program will take:
Error #2044: Unhandled IOErrorEvent:. text=Error #2036: Load Never
Completed
When program Catches that error logically, it means there is no file name like Slide21.jpg. Which means total image number is 20. I want to go back when take at first time that error. Thanks for any advice
var totalImages=100;
var imageNumber=1;
var myLoader:Loader = new Loader();
//************LOADING IMAGES TO STAGE********************//
//elearningau.com/nondynamic/
var myRequest:URLRequest = new URLRequest("http://elearning.com/upandshow/Images/Slide"+imageNumber+".JPG");
myLoader.load(myRequest);
addChildAt(myLoader,1)
rightButton.addEventListener(MouseEvent.CLICK, nextImage);
function nextImage(event:MouseEvent){
if(imageNumber<totalImages)
{
imageNumber++;
} else {
imageNumber = 1;
}
reload();
}
function reload(){
removeChild(myLoader);
myRequest= new URLRequest("http://elearning.com/upandshow/Images/Slide"+imageNumber+".JPG");
myLoader.load(myRequest);
addChildAt(myLoader, 1);
}
You need to listen for errors:
myLoader.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
function ioErrorHandler(event:IOErrorEvent):void {
// this means there was an error - do whatever you want
}
We need to modify/update the xml attribute of .idms file. using actionscript. I'm using below approach to do that.
protected function windowedapplication1_creationCompleteHandler(event:FlexEvent):void
{
var file:File = File.desktopDirectory.resolvePath('myInputFile.xml');
var fileStream:FileStream = new FileStream();
fileStream.open(file, FileMode.READ);// doesn't read processing instrunction
var xml:XML = new XML(fileStream.readUTFBytes(fileStream.bytesAvailable));
fileStream.close();
var writeStream:FileStream = new FileStream();
writeStream.open(file, FileMode.WRITE);
for each(var node:XML in xml.descendants("*"))
{
if(node.localName() == "Link")
{
var linkfile:String=node.#LinkResourceURI = "file:/Shared/Logos/Bk.ai";
}
}
writeStream.writeUTFBytes(String(xml));
writeStream.close();
}
In above code problem is that it does not read processing instruction on top of xml file. in result after writing the xml file, it won't read the file as InDesign snippet file anymore.
Processing instrunctions are:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
Can anyone help me in figure out how I can I read the processing instrunction as well in new file ?
Thanks for quick reply but Even though I've made this property as flase it's keep ignoring the processing instuction.
var file:File = File.desktopDirectory.resolvePath('031413115849909.idms');
var fileStream:FileStream = new FileStream();
XML.ignoreProcessingInstructions = false; //newly added
fileStream.open(file, FileMode.READ);
var xml:XML = new XML(fileStream.readUTFBytes(fileStream.bytesAvailable));
fileStream.close();
There is a static property in the XML class called ignoreProcessingInstructions (which is true by default) that you could try setting before reading in your file. See this help page.
After some Google-ing, it appears that processing instructions outside of the root node may not be available, since the XML object starts with the root node. In that case, you may have to read the file in as standard text, save the processing line(s) before the root node, and then write them to the output file before you write the actual XML contents.
I have an issue with Workers in AIR : when I try to open a file in a non-primordial Worker, I get a Security error. When I try the same code in the primordial Worker, it works well.
I load another swf and pass its bytes when creating the second Worker.
First, I tried with URLLoader (code in 2nd worker) :
// Loading XML test
var loader:URLLoader = new URLLoader(new URLRequest('app:/config/generator/galaxy.xml'));
loader.addEventListener(Event.COMPLETE, function(evt:Event):void
{
// Trace
CEThreadDebugger.log(XML(loader.data).toString());
});
loader.addEventListener(IOErrorEvent.IO_ERROR, function(evt:IOErrorEvent):void
{
CEThreadDebugger.log(evt.text, CEThreadDebugger.ERROR);
});
loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, function(evt:SecurityErrorEvent):void
{
CEThreadDebugger.log(evt.text, CEThreadDebugger.ERROR);
});
I get this error :
[LOG]ERROR->Error #2048: Security sandbox violation: app:/SombresCieux.swf cannot load data from app:/config/generator/galaxy.xml.
Then I tried with File :
var file:File = File.applicationDirectory.resolvePath('config/generator/galaxy.xml');
var stream:FileStream = new FileStream();
stream.open(file, FileMode.READ);
var xml:XML = XML(stream.readUTFBytes(stream.bytesAvailable));
stream.close();
And I get this error (my code is in _mainToWorker method) :
[LOG]INFO->Error #0 : SecurityError -> file
SecurityError: file
at flash.filesystem::File$/initAppResourceDir()
at flash.filesystem::File$/get appResourceDirectoryPath()
at flash.filesystem::File$/get applicationDirectory()
at generator::Generator/_mainToWorker()
at engine.generic.system.concurrency::CEThreadMain/Evt_mainToWorker()
I noticed that the error comes from this line alone :
var file:File = File.applicationDirectory.resolvePath('config/generator/galaxy.xml');
So it works in the primordial Worker (main app), but not in the threads...
Can't the Workers access system's files nor load any file ? It's a quite huge limitation...
Thanks for the replies !
public function createWorker(swf:ByteArray,
giveAppPrivileges:Boolean = false):Worker
giveAppPrivileges:Boolean (default = false) — indicates whether the worker should be given application sandbox privileges in AIR. This parameter is ignored in Flash Player
