I am trying to upload and download a file from the server. After uploading if I Try to download the file it is not downloading. URLStream.bytes Available returns incorrect value. If I close the AIR application and try it ,it will work perfectly.. Why URLStream.bytesAvailable returns incorrect value just after uploading..

I am an intern trying to fix a problem with an XMLsocket outputing the wrong byte size, stored in a byte array, for the file. Anyone know why a XMLsocket would be output the wrong file size/byte size for a file?
View 1 RepliesI'm just trying to make a sprite follow the last letter of a TextField with the getCharBoundaries() function. It works fine when the DisplayObject that contains the TextField has no 3d transformations on it. But when I rotate it in 3D, returned values are wrong and it doesn't work anymore.I don't know anything about the matrix objects and all those transformation functions but I guess there is a way to get the correct value by using one of those matrices.I tried to use some matrices and played with some of their values but didn't get any luck.
View 1 RepliesI can get which part of file in bytes is loaded using videoDisplay component for RTMP protocol for VOD, I can get the current playing position using videoDisplay.playheadTime. But I want to know how many seconds of video are already loaded (not the length of bufferTime, which remains constant). i used videoDisplay.bytesLoaded when using RTMP it returns nothing ,if we uses HTTP it displays number of bytes loaded
The loaded size in bytes is not directly proportional to running time of the video, and while using rtmp im unable to get bytesLoaded too, how i can calculated the Video already loaded.
how can I get the bytes loaded and bytes total, from a JPG i'm loading using loadMovie? the point it's making a loadbar
Code:
image.loadMovie("pic.jpg");
What I'm trying to do is get the total bytes of all the files I want to load and display the percentage loaded of total bytes and bytes loaded of all the files. Its a slideshow so i want all the files loaded and then it will play. I've looked at bulk-loader but it wasn't what I needed. The image are loaded from an xml file. I think I would need to create an Array and then find out the total bytes but I don't know how to reference the loader in the progress.

I have a load file and a write to file method. We all know what they do. How ever load always returns true and write always returns false....Right there you know somethings wrong. Because The forums have an issue with me posting code...I posted it here: [URL] Based on this code what is the issue here? why is write always returning false and why is load always returning true? (even for files that do not exist). My understanding is that if flash cannot find the file it should write to it will create it and if it cant load said file, then that method should return false.
View 6 RepliesI'm having with a menu navigation system. I'm using Flash MX. I have created a menu system for the site I'm building ([URL]) where one of the buttons "Choose photographer" drops down a list of names. All the other buttons just jump to another page. The drop down is currently using tweens also the logo moves to the left as the dropdown appears and returns when the dropdown returns. All working fine apart from its a bit jerky.
It's I just wanted to get away from tweening and use action scripts instead, as I'm a newbie to all things Flash I trawled the net for tutorials and examples so that I could cobble together the exact same effect. I have managed to get the drop down work and return using the action script and it does seem smoother and works slightly better. But can I get the logo to move to the left and back in time with the drop down...no.
I'm using URLStream to download 30-80mb files over HTTP. It downloads fine on Windows XP, but is extremely laggy in OSX. Anyone had similar issues? Here's some snippets of the code.

I'm trying to open a connection to a URL that will periodically send over a JSON object. I know that I need to use URLStream and some event callbacks, but I'm in the dark when it comes to knowing how streams of data "work," or the general flow of operations. Assume I know how to open the connection and send the correct request headers. First, some relevant code:

I successfully built a XML gallery; everything seems to work fine. But everytime I click on a thumbnail, I will get the following error:Error: Error #2029: This URLStream object does not have a stream opened.I researched on this error, and it seems this error involves sounds. Something about trying to load something that's already fully loaded. Therefore, I'm confused since I don't have any sound in my gallery. On top of that, the gallery works just fine but this error keeps popping up in Flash.[code]

View 2 RepliesIn my AIR app,I am trying to implement a file downloader using URLStream.
public class FileDownloader {
// Class to download files from the internet
Function called every time data arrives[code].....
I simply create an object of the above class and passing the url and the file and call the load function. For some files I get the following error.
remotePath: http:[url].....error while writing bytes from...Error:Error #2029: This URLStream object does not have a stream opened.Which means the error is from the file stream(fileAccess) that I am using. I am unable to figure out why this could be happening. If I try to open the url http:[url]... in the browser, it opens properly. This happens randomly for some files.
I'm attempting to connect to an existing Comet-style long-poll service using an AIR app. The service expects a client to make a GET request with a Connection: Keep-Alive header. This request will remain open for long periods of time so that the server can push data through. In my app, the connection is terminated with an IOError after 30 seconds.
Is this an undocumented limitation of URLStream? A restriction on adl (I've only been running my app through adl)?
The server does not send any "keep-alive" messages to the client but, unfortunately this is not something i have control over.
Update
To test this, I've set up a stripped-down version using a little php script (linked by leggetter below) and am hitting it from a simple AIR app. I'm finding that my connections are closed after 30 seconds whether I use URLStream or URLLoader. the PHP:
<?php
set_time_limit(0);
sleep(40);
[Code]....
If i adjust the initial sleep time in the php script to anything over 30 seconds, the IOError event is triggered. If I lower the sleep time, but the request continues adding data past 30 seconds, the onComplete event is called, but _urlLoader.data is empty.
The only way this process completely successfully is if the entire thing is over before 30 seconds elapses.
In my case I need to be able to cancel loading as the user could possibly be scrolling through alot of images and the if not canceled it can take a few minutes to catch up to the scroll position.So after research the URLStream class seems to cure this problem and I found a good streaming class hereThis class works very nice except when there is heavy load on the server causing lag.When this lag happens the class will dispatch the complete event yet the image will not show.Watching the download with HTTPFox shows the image in fact does get loaded.
I assume there is some kind of delayed issue with the URLStream class and the author of this class tried to correct it using the setTimeout method. I also tried delaying the dispatching of the complete event using a timer and not dispatching until if( this.width != 0 ) was detected and this seemed to work much better.But it is still haunting me just not as often.
I have to be able to cancel and kill a Loader process properly and many times. If I dont do this, it seems that the flash player (at least on mac) eventually crashes as some loader processes are flying about , strangling the CPU.
There doesnt seem to be a straightforward way to know this and just calling a Loader.close causes an error, if the stream is not open.
Is anyone else aware of the fact that Internet Explorer (at least version 8) keeps downloading a file even if the close() method is called on an URLStream instance? Heck, it even keeps downloading if you close the tab displaying the site which called the load()/close() methods on an URLStream instance. Does anyone know of a solution to overcome this problem? More details: My preloader is loading a dozen of files and immediately closing the download streams with the purpose of checking each resource's file size. In Mozilla Firefox all goes well, exactly as expected, but Internet Explorer keeps downloading the resource even if the stream has been interrupted by the action script close() method.

I'm writing a Comet-like app using Flex on the client and my own hand-written server.
I need to be able to send short bursts of data from the client at quite a high frequency (e.g. of the order of 10ms between sends).
I also need the server to push short bursts of data at a similarly high frequency.
I'm using NetConnection.call() to send the data to the server, and URLStream (with chunked encoding) to push the data from the server to the client.
What I've found is that the data isn't being sent/received as soon as it's available. For example, in IE, it seems the data is sent every 200ms rather than as soon as NetConnection.call() is called. Similarly, URLStream isn't making the data available as soon as the server is sending it.
Judging by the difference in behaviour between the browsers, it seems as though the Flash Player (version 10) is relying on the host browser to do all the comms. Can anyone confirm this? Update: This is very likely as only the host browser would know about the proxy settings that might be set.
I've tried using the Socket class and there's no problem with speed there: it works perfectly. However, I'd like to be able to use HTTP-based (port 80) connections so that my app can run in heavily fire-walled environments (I tried using a Socket over port 80, but that has its problems).
Incidentally, all development/testing has been done on an internal LAN, so bandwidth/latency is not an issue.
Update: The data being sent/received is in small packets and doesn't need to be in any particular format. For example, I might need to send a short array of Numbers, and this could either be encoded in AMF (e.g. via NetConnection.call()) or could be put into GET parameters (e.g. using sendToURL()). The main point of my question is really to see whether anyone else has experienced the same problem in calling NetConnection/URLStream frequently, and whether there is a workaround (it's also possible that the fault lies with my server code of course, rather than Flash).
This is absolutely driving me crazy. While I'm a fan of the availability of asynchronous calls in AIR, I'm finding that being forced to use them for something that should be SUPER simple is a severe limitation. So severe that I may end up abandoning AIR and writing native Android and iOS apps instead of using the shared AIR platform.
OK, now that I have that off my chest, here's what I'm trying to accomplish. I have an app that, when deployed, is relatively small. But once deployed to a user's device that user will log in using a login name/password. Once they log in, content specific to that user needs to be downloaded and saved to the local device. Since the content varies by user I can't include it in the package for deployment.
But I cannot figure out how to accomplish this: say I want to download 10 files and each file is 2-3mb and I want to show a "Downloading, please wait..." view during the download. The application cannot proceed until all 10 files are downloaded. But since from what I've seen URLStream and URLLoader are both async I cannot figure out how to block the app from opening the "View available content" and say on the "Downloading, please wait..." view.

Shoud I take float from the URLStream with readFloat() or plain bytes with readBytes()?
