ActionScript 3.0 :: Polling With URLLoader Gives Sporadic IoError #2032?
Jul 8, 2008
I have a flex app that polls a php script every 1-2 seconds and returns new data. The polling is done with a URLLoader.load call;the requests are HTTP GETs. The app listens for Event.COMPLETE, handles the incoming data, waits for 1 second, then makes another URLLoader.load call.
This process works perfectly for any duration from 4 to 20 minutes. Eventually, a URLLoader.load call fails to return Event.COMPLETE. Instead it hangs for 60 to 180 seconds (depending on which local network I'm using for internet access) and finally returns an ioErrorEvent.IO_ERROR with the message "Error #2032: Stream Error. URL: <mysite.com/foo.php". The app tries to make another URLLoader.load call, but from this point onward, none of the loads return Event.COMPLETE. Also, none of these post-error HTTP GETs appear in the access.log file of my apache (2.0.55) webserver. The app will not work again until I close and reopen the browser.
I've spent several days trying to figure this out! The time until the app crashes appears to be completely random. The problem occurs in both Firefox (2.0.0.15) and IE (7.0.5730.11). I've read that sometimes 2032 errors can be related to caching, but there's no directives (in .htaccess file or httpd.conf file) that sets the Pragma or Cache-Control response header to "no-cache".
I can't tell if the problem is on client or server end. Based on the adobe language references and the forum posts I've read, this seems to be an appropriate use of URLLoader. (In case you're wondering I want the app to respond to events in near real-time. I originally used xmlsocket to push data to app from server. However, this communication is blocked by corporate firewalls, so I need an alternative method)
I have a project that was already supposed to be launched. It tested fine on my computer, but is throwing an error on other browsers....and I cannot figure out how to catch the error! I have been reading and trying everything, but nothing is working!!!
I captioned a video using components, but the captions are stored in the video and the source then is "0". Flash doesn't understand "0", but the captions still work. I need Flash to ignore the error so it stops crashing the browsers!
I'm getting IoError 2032 when attempting to login from the mobile actionscript-facebook api. Specifically I'm getting this error on my android 4.0 device. Strange thing is, it was working fine about a week ago.
When my PNG encoded data is sent to my uploader php file its throwing an error the very first time and only after I havent done it in a while... half an hour maybe... it says this:
Then when I press the button a second time it goes through fine. If I close and re-test the movie its fine the only way to reproduce it is to wait a while and try it for the first time. Any clues whats causing this?
I�m getting Error #2032 when my URLLoader complete event finishes firing. What I can�t figure out is why. The complete event fires successful (I ran a number of trace statements to make sure it made it all the way to the end of the method with no error) and I�m not getting any helpful output when I trap the IOError. Here is the error message:
I'm creating a flash basketball bracket that I need to submit the picks to a MSSQL database on an ASP.NET server. Every time, I get the #2032 Stream Error, which usually means the URL doesn't exist (which it does). The thing that chaps my behind is that if I trace the url and the variables, then paste that into a browser window, the database updates perfectly, just as I want it to. My code is below. Of course, the tournament is ten days away and I've been stuck here for a week, so if anyone can see what the heck is going wrong, please let me know.

I have an swf that sends info to a PHP file which in turn gets a SWF to FLV converter running. If I try this with a small 1kb swf file it works great and returns the results with in 5 seconds.However now that I step it up to convert the files in which it was intended, files ranging around 2 mbs, I get this error..
I have a function in my AS3 that frequently calls a PHP file. Most of the time it works but occasionally it fails and throws the error I used in the title. I researched this fairly extensively and started capturing the event in the following manner:
public static function Bar():void { var request:URLRequest = new URLRequest("path/to/file.php"); var requestVariables:URLVariables = new URLVariables(); var loader:URLLoader = new URLLoader();
I am trying to display database details in a Flex datagrid and connected using HTTP Service. It was able to display details without any issue when I was working in the FlashBuilder 4.5, however, I deployed the bin-debug part in the Tomcat webserver to access it globally.
I am experiencing this error message when I am trying to access the swf file "HTTP request error Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032"]. URL: http://localhost:8084/UA/details.jsp"
I tried to create the crossdomain.xml file and deployed in the root directory but still experiencing the same error.Here is my crossdomain.xml :
<?xml version="1.0"?> <!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd"> <cross-domain-policy>[code].....
which everything seems fine, but when i implement a slider on a page inside a folder in the root (i.e. aboutus/index.aspx) i get that error when the slider is trying to call the images.I have similar slider animations in pages located in the root folder and in those i get no problem at all, seems it only happens when the page is located inside a folder.The website is done using main.master on asp, maybe the cache or rendering of the website is missing something, hope someone has had something similar or know how to get around this.
I have a character on the stage in my fla that when hitting a particle created in an a particle.as removes the particle. I have the code for removing the particle and also a score counter that adds one everytime a particle is removed (located in my particle.as). My problem is the score keeps resetting or I get sporadic results (not sure which) for example here I traced the results; 16 17 24 18 7 23 24 25
On the stage I have a dynamic text field called score_txt, that displays my score. Code: package { import flash.display.Sprite; import flash.display.Shape; import flash.events.Event; import flash.utils.Timer; [Code] .....
The slider thumbs in my Flex 3 application usually work correctly, but often they seem to become insensitive to mouse downs on what should be thumbPress events. It turns out that mouseOut events are being fired as the mouse moves away from the edge of the thumb towards the center. The thumb is sensitive to mouseDown events only when it is in the "over" state.
I am seeing the same behavior: Displaying the default thumb rather than my custom class Using a hitArea sprite (I tried a child TextInput sized to cover the thumb with alpha 0). Can anyone suggest either a fix or a workaround? I can identify the faulty mouse out events, but then don't know how to compensate, for example, by reestablishing the "over" state, or perhaps with programmatic control of the mouse.
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:
This is one of those rich media interactive ads, that have the ability to launch another SWF using _root.myPR.openPanel(1); The user has 3 choices identified as option1, option2, option3. I would like to not just openPanel on pr_submitBtn.onRelease, but to have the panel open & advance to a particular frame depending on which option the user chooses in the poll. I have the following launching the panel but not going to different frame labels in the panel launched. All 3 options simply stop on frame "one".
Code: if (option1 = true) {_root.myPR.openPanel(1, "one"); } if (option2 = true) {_root.myPR.openPanel(1, "two");
So I have streaming video coming in, and I want to know when it is buffering. This is fundamentally not that hard, just adding an EventListener for some type of buffering event, but I was wondering if this is necessarily the "best" way to do it.
My other thought was setting up a timer that polls the video feed every X milliseconds asking it if the video isBuffering(), or somesuch. While I could, in the worst case, wait the full X milliseconds before querying the video stream, I've decided that this doesn't actually matter to me; I can work around it, and indeed do so quite naturally already.
So I'm asking: is there substantial overhead involved in having an EventListener (assuming I already have quite a few), or is the advantage of catching the buffering event right away sufficiently appealing?
I'm building a remote presentation tool in AS3. In a nutshell, one user (the presenter) has access to a "table of contents" HTML page with links for each slide in the presentation, and an arbitrary number of viewers can watch the presentation on another page, which in turn is in the form of a SWF that polls the server every second to ensure that it's on the right slide. Whenever the admin clicks a slide link in the TOC, the database gets updated, and on its next request the presentation swf compares the label of the slide it's currently displaying to the response it got from the server. If the response differs from the current label, the swf scrubs through the timeline until it finds the right frame label; otherwise, it does nothing and waits for the next poll result (a second later).
Each slide consists of a movieclip with its own nested timeline that loops as long as the slide is displayed. There's no actionscript controlling any of the nested movieclips, nor is there any actionscript on the main timeline except the stop();s on each keyframe (each of which is a slide in the presentation).
Everything is built and working perfectly. The only thing that's troubling is that if the presentation swf is open for long enough (say, 20 minutes), the polling starts to have a noticeable effect on the framerate of the movieclips animating on any given slide. That is, every second, there's a noticeable drop in the framerate of the animations that lasts about three-tenths of a second, which is quite noticeable (and hence is a deal-breaker for the whole presentation suite!).
I know that AS3 has issues with memory management, and I've tried to be diligent in my re-use of objects and event listeners. The code itself is dead simple; there's a Timer instance that fires every second, which triggers a new URLRequest to be loaded by a URLLoader. The URLLoader is reused from call to call, while the URLRequest is not (it needs to be initialized with a new cache-killing value each time, retrieved from a call to new Date().time). The only objects instantiated in the entire class are the Timer, the URLLoader, the various URLRequests (which should be garbage-collected), and the only event listeners are on the Timer (added once), the URLLoader (added once), and on the routines that scrub backwards and forwards in the timeline to find the right slide (and they're removed once the correct slide is found).
I've been using mr doob's stats package to monitor memory usage, which definitely grows over time, so there's gotta be a leak somewhere (it grows from ~30 MB initially to > 200 MB after some scrubbing and about 25 minutes of uptime).
Apart from using BlazeDS, are there any pre-existing libraries that implement long polling (or server push) in Flex?I've read I like to implement Flex to Server comet / long polling for games, but he's only asking if it's possible to implement... Not if implementations exist.
I recently migrated to Flash CS4 from Flash 8 and occasionally there is a bizarre jolt that briefly shifts all the panels before returning to normal. Is this a glitch? I'm running Windows XP 32-bit. I've noticed this across all workspace layouts I've used so far.
ScenarioI have a main movie which launches slides dynamically via xml.Within that xml i'm calling a slide which loads another swf called Quiz.That Quiz file loads its questions via xml.IssueWhen I play the outermost swf (the main movie), it starts to load (I can see the border graphic) but throws an XML IOError.
If I just play the quiz swf in the media folder from which the main movie pulls, it works fine. Therefore my assumption is that the xml for the quiz is not loaded before the quiz slide is pulled into the main movie.Directory structure and calls are correct.
I need to let people upload a .pdf document there are other places on my site that allow people to upload .jpg which are usualy a fairly small file size.Well I need them to be able to upload a .pdf which is considerably larger.The problem is that every time I atempt an upload, it gets to about 65000 bytes and then results in an IOError.
I'm trying to get my swf to show the url of an attempted file loading operation when it fails (IOError). For some reason (security?) it works fine in the flash debug environment, but it doesn't in the browser. In flash it shows:
I want to make some buttons invisible until the print job is done.So I have simply set the alpha to 0 when the print button is clicked.At the end of the printjob I want the exit button to be visible again.I have a 2 second timer that sets the alpha back to 100.It works fine when someone actually prints, but if someone hits the print button and then cancels without printing, the timer never fires.I was looking for a way to catch the canceled print.[code]
I have now ran into Flex Fileupload problem on ssl as many others have. I simply get an IOError, no other information as to what caused the error was given, ssl handshake or something else. How do I nail down the cause of the error? I tried using the ';jsessionid=' trick, still no luck. FYI, I am running on local https server, with self signed cert. Everthing works fine without ssl. With ssl, it only works on IE (FF, Chrome, Safari fails on https). With other browsers, server doesn't even get the request.
