Actionscript 3 :: Catch And/or Deal With "Error #2030: End Of File Was Encountered" On A NetConnection ?
Mar 30, 2011
I'm currently writing a client in ActionScript 3 that talks to a Red5 application/media server via a NetConnection object. The server sends the client multiple types of data over this connection including video, audio and remote procedure calls. After an indeterminate amount of time (sometimes 10 seconds, sometimes 10 minutes) I see the following error in a popup window from my Debug version of the Flash client:"Error: Error #2030: End of file was encountered."
I'm in the process of trying to figure out what's causing this error and the thing that's really driving me nuts is that I can't seem to catch it. I realize that the error probably indicates some low-level network read failing, but the fact that it generates a popup window in the debug flash player implies that I should be able to catch it.Since the error has no associated stack trace, I went so far as to add the an uncaught exception handler on my base Sprite object:
public class MyClient extends Sprite
{
public function FOWClient()[code].....
My uncaught exception handler will get called properly if I purposely throw in some errors, but it never gets called when this Error #2030 happens.How the heck can I catch this "End of file was encountered" error and deal with it in code? If I can't catch it, are there any thoughts on what's causing it and how I fix that? I've narrowed it down to having to do with RPC calls being made from my server to my client because when I disable those, but leave audio & video, I don't see the issue. Unfortunately, I don't yet have any good ideas beyond that.
I created an equalizer that works great, except every once in a while It throws the Error #2030:End of file was encountered error. Here is the code for the equalizerwhat is causing this?
var ba:ByteArray = new ByteArray();var frameHalf:Number = 0;var framePlay:Number = 2;addEventListener(Event.ENTER_FRAME, loop);function loop(e:Event):void{ if(frameHalf == framePlay) frameHalf = 0;
In the 4th line in the code above i am getting "Error: Error #2030: End of file was encountered." I checked the length of the pixels object which is 4 times the width*height of the rect object. Given that setPixels() functions reads unsigned int from bytearray and sets that value to pixels, I think it should work.
But I have no clue why this wont work. The pixels object is filled after RLE decoding of the data which i get from a server.
Is there any work around or any other method which I could try to use. The loader class wont work as the data that I get from the server is not in any of the recognized format.
I was testing out some applications written in AS3 and it worked fine untill I encountered one app when I got the Flash10i.ocx error message. I uninstalled and re-installed the flash player and this time when I run the application I got the Flash10k.ocx error. I am using IE 7 and Flash CS5 and my OS is Win XP professional. I am trying to go through the code to see if there is any issue. Meantime I am posting the code here, if anyone is able to spot any issue with the coding do share with me. The code is from the book 'Learning Flash Media Server 3':
myasfile.as holds my code, and starts with "@estr = function ()" When I go to export movie, I get "myasfile.as, Line 1 unexpected '@' encountered" Why do I get this message?
I'm not sure about the purpose of the throw statement.What exactly does it do in the following example?Does it throw the error message on the screen?The manual is silent about what the throw statement does upon execution.The throw statement
Flash Player and Adobe AIR throw exceptions when they encounter errors in your application at run time.In addition,you can explicitly throw exceptions yourself using the throw statement.When explicitly throwing errors, Adobe recommends that you throw instances of the Error class or its subclasses.The following code demonstrates a throw statement that throws an instance of the Error class, MyErr,and eventually calls a function,myFunction(), to respond after the error is thrown:
var MyError:Error = new Error("Encountered an error with the numUsers value", 99); var numUsers:uint = 0; try { if (numUsers == 0)[code]......
Notice that the catch statements are ordered so that the most specific data types are listed first.If the catch statement for the Number data type was listed first, neither the catch statement for the uint data type nor the catch statement for the int data type would ever get executed.
I'm calling a function in my actionscript called GrabWidget() from the javascript. When I do this from a plain page with just the flash and the javascript link, everything works flawlessly. However, when I add this to a page, I get the error: uncaught exception: Error in Actionscript. Use a try/catch block to find error.I've even gone so far as to empty out the contents of GrabWidget() in my actionscript and I still get the error.
I have a password text box set up and for the submit button I have this script and it keeps giving me errors.. Basically I want to say if the password = one then go to this url ... if password is = two then go to this URL if it is none of them go to the next frame.
I want to count the online user,when each client login the system,it's connecting to the server and increase a variable stored in a remote shared object.But when client connecting server,problems arises:Error #2126: NetConnection object must be connected
My web layout:

Code snippets:
rtmpnc = new NetConnection(); rtmpnc.objectEncoding = ObjectEncoding.AMF0; var uri:String = ServerConfig.getChannel("my-rtmp").endpoint + "/userLogin"; rtmpnc.connect("http://202.206.249.193:2367/userLogin");
Is there any way to catch any error within Flex application and send it via let's say email or record it somehow (this emailing or recording part is not the problem, just error catching for whole application is).
I have a single server that runs IIS and FMS, both on port 80. The server has two internal IPs assigned to it, one for IIS and the other for FMS. I also have two static public IPs. My router maps one public IP to IIS' internal IP and likewise for FMS.
IIS works fine. Using an online port scanner, I was able to determine that port 80 is responsive for both public IPs. Before I had configured my Adapter.xml and fms.ini, only IIS' public IP was responsive. This seems to indicate that FMS is fine.
However, when my ActionScript creates a NetConnection and calls connect(), my netStatus callback takes about half a minute to be invoked, and I get "NetConnection.Connect.Failed". Which is not very informative. Is there a way to get more info about the cause of the error?
I have an air application, in which the user types javascript in a textarea, and it is eval'd in an mx:HTML component, but even with try/catch around the eval, and around the code in the eval, and an HTMLUncaughtScriptExceptionEvent handler, it still throws an error. htmlWindow is html.htmlLoader.window.
In Flash AS3 i wanna write the single try catch block in order to catch any errors in whole class. For ex, i have a lot of functions in myClass.as. I don'w wanna write in each function try catch blocks in order to catch errors in this function. Is there any methods to do this?
import flash.display.*; var bmp:BitmapData = new BitmapData(Stage.width, Stage.height, true, 0);; attachBitmap(bmp, 2, "auto", true)[code]...
Throws this error:
*** Security Sandbox Violation ***Connection to null halted - not permitted from file:///~test.swf .Despite the error description, the video plays fine, it's the bmp.draw which fails. If I move the ns.play before the bmp.draw, it works?!
I am currently building a Flex application with a PHP backend. The flex application should talk to the backend using Zend_AMF.I have implemented the Zend_AMF endpoint as a controller, so it is accessible via http://localhost/myapp/amf.I am trying to test the service using a service browser called ZamfBrowser.When connecting, I get this error:
There was an error loading the server's info. Error: (mx.rpc.events::FaultEvent)#0 bubbles = false cancelable = true
When loading certain .swf files into a WebView, a split second after the flash file begins to be displayed, my app closes with a Signal 11 fault. No exception is thrown that I can see. Example LogCat dump here.When loading the same .swf files into the stock Android browser, instead of closing, an error icon is displayed. Touching it opens a pop-up stating: "Adobe Flash; Insufficient Memory". Is there any way to catch the Insufficient Memory error before the SIGSEGV occurs -- preventing the task from being terminated -- as is done by the stock browser?
Note: I'm testing under Android 2.2 with the HTC version of the Flash plugin, but it appears that the same sort of issues occur on other, non-HTC devices. I'm loading the swf file into the WebView directly, using:
webView.loadUrl("http://whatever.com/bla.swf");
(with plugins and JavaScript enabled). It works perfectly in most cases -- only a few files cause problems. I've tried various suggestions for reducing memory (such as clearing the WebView caches) without success.

I'm trying to write a Flex client that interacts with a Spring-Flex java application. I would like to catch (the flex equivalent of) SecurityExceptions and Display an error page if the user was trying to do something they aren't allowed to dox op up a login box if the user wasn't logged in According to the Spring-Flex docs,
I'm loading info from a mySQL database through Flash/AS3 --> PHP then back to Flash. I'm not really certain if we're going to know how many times to try and load from the database. I'm getting an error from URLVariables right now from the constructor (Decode ()) when Php sends me nothing. (I'm out of database info) I would like to error handle this so my program doesn't crash. I looked it up in the documentation and it says that the constructor ( Decode () ) throws "Error" when this particular type of thing occurs.
I have a Flex and Java application and i am using BlazeDS between flex and java. Generally my application works fine. I observed when ever i try fetch data little faster(not giving gap between two fetch commands) then i am getting the error "Server error :faultCode:Channel.Call.Failed faultString:'error' faultDetail:'NetConnection.Call.Failed: HTTP: Failed'"
I guess when ever load is increasing on BlazeDs, i am getting the error. I am calling the java service using following code
I'm making application with ability to copy system files and I need to show copying progress. Can anyone show some examples,I'm trying to use FileStream class, but I seem to lack experience.
I've searched for a good while but I can't seem to find an answer to this question:How to catch all errors of an external SWF file when it's loaded?The story:I'm building a flash app that would upload and then load any user-created SWF file and display it if it doesn't throw errors.I've tried to use try/catch statement but it doesn't seem to catch internal errors of the loaded SWF.
