I have a problem with my Flex-Application. As you can see in the code-sample below i try to add some panels to a vgroup. The panels are getting their title from my MYSQL db. My problem is that I can't wait on the async call of the callresponder, so the panel doesn't get filled. How can I wait for the data from DB?If i try to build a new panel with a button it works. When i press the button one panel appears with the right title.
I am using Flex and Actionscript 3, along with Webservices, rpc and a callResponder. I want to be able to, for example, say:
loadData1(); // Loads webservice data 1 loadData2(); // Loads webservice data 2 loadData3(); // Loads webservice data 3
However, Actionscript 3 works with async events, so for every call you need to wait for the ResultEvent to trigger when it is done. So, I might want to do the next request every time an event is done. However, I am afraid that threading issues might arise, and some events might not happen at all. I don't think I'm doing a good job of explaining, so I will try to show some code:
private var service:Service1; var cp:CallResponder = new CallResponder(); public function Webservice()[code]....
I could ofcourse save the actions in an arraylist, but whose to say that the addToArrayList and the check if other calls are available do not mess eachother up, or just miss each other, thereby halting execution? Is there something like a volatile Arraylist?
I want to create a high performance server in C# which could take about ~10k clients. Now i started writing a TcpServer with C# and for each client-connection i open a new thread. I also use one thread to accept the connections. So far so good, works fine.
The server has to deserialize AMF incoming objects do some logic ( like saving the position of a player ) and send some object back ( serializing objects ). I am not worried about the serializing/deserializing part atm.My main concern is that I will have a lot of threads with 10k clients and i've read somewhere that an OS can only hold like a few hunderd threads.
it most used on network accesses. But now, I have a class that will do several things, including but not limited to network accessing, many many single loops within a huge code(maybe). The return time is unspecific, so I think about using an async method. However, when I run my program, I found that all things in call stack are stuck when the loop running. I made a short version of my code. First, the weird AsyncClass.as class is like this:
in a AIR mobile project I've done an initial loop that call a class that save images listed in an xml file to the applicationStorageDirectory of the device (iPad/android). With png files I have no problems since I got a jpg file. All files are correctly saved into the directory, but when a jpg occours it stops the save process (so the jpg is the last file saved and the loop on the list is incomplete, no others pngs are saved).
I will call flashObject.httpRequest to complete a http request via flash. The problem is there is no reference about httpRequest is an async method or sync. It is important for my application.
private function httpRequest (uri:String, param:String="", method:String="GET"):void { var
I am aware that Action Script does not provide multithreading so when writing flex application we are limited to work on one thread. which is ok for rendering my UI.
However some questions arise when preferring flex over silverlight:
As a UI layer single thread is good enough but is it fair to assume that for Aync httpservice like operations in flex , internally it would use some worker threads to manage the async operation and then come back to the main thread ? it looks like it does since my UI does not freeze.Can the flex/flash player deal with multiple httpservice calls in parallel ? ( e.g more than one section of the UI loading data at the same time.)How about the animation stuff ( e.g the parallel animation ) - does flash player internally leverages some threading for accelerating graphics or is it all done on the UI thread ?
user clicks a button sends a Loader to see if the user has permission if the user has permission uploads a file
Unfortunately, this gives:
SecurityError: Error #2176: Certain actions, such as those that display a pop-up window, may only be invoked upon user interaction, for example by a mouse click or button press.
It appears that as a security feature, Flash 10 disallows certain functions (such as uploading a file) unless it is preceded by a mouse click or button press. However, since I am first loading the request for permission, it no longer see the MouseEvent event (presumably in the stack) and thus throws a SecurityError.
I'm having a weird situation that only seems to occur in IE. This may or may not be related to my other post ("Need to worry about thread-safety?"), but I'm not sure, so I'm putting this in a separate thread.I have a setup in my my flash app to load an arbitrary number of different sounds, but with an limit on the number of sounds being loaded simultaneously. It works like this (psuedocode):
EDIT: In other words, it starts loading up to the first, say, 5 sounds, and then after each one finishes loading, it starts loading the next sound in the queue.It works fine on everything except IE. And it will work on IE as long as the files aren't cached. But if they are cached, then in IE (and only in IE) the flash app will hang and produce a trace like this:
a b start callback start callback
[code]....
And after roughy 50 of those "start callback"s the flash app hangs and it never gets to any "end callback" or "c".It seems that loadSound is deciding to call onLoad synchronously, instead of asynchronously as would normally be expected. But this never seems to happen in anything but IE, even when the given browser has it all cached. So apparently it's either calling onLoad the wrong way in IE, or flash events like onLoad are susceptible to race conditions and need to be written accordingly.
I have a typical Flex-based application that was written to use a Java/Hibernate/MySQL backend. The client changed the requirements - now they want to distribute it on a CD where the user can just run the app without any installation or a network connection.
To do this, I certainly need to eliminate the web server and the database server and adapt my application (with as few changes as possible, of course) to a stand-alone application that will fit on a CD/DVD. I've managed to export the data to XML and read it into Flex, but I'm wondering if there's a way to recreate the Hibernate data structures in Flex so I could change as little code as possible. Failing that, is there any way to keep the existing Java/Hibernate external to the Flex code but retrievable without installing Apache Tomcat or MySQL?
I have a Flex application which manage a database composed by 7 tables.I have created the insert form and all work great. Now I wanto to improve the Form performances; the idea is to replace the TextInput of the Form with ComboBoxes which are provided by the DataBase tables
In my table the Collation is:latin1_swedish_ci (but i tried UTF8_unicode too).In my flex application when it shows the table,it displays it correct,with all accent and pointing correct,but in the table is like :
I get the alert but I can't get the lightbox window to display. When my as code makes the ExternalInterface call I get what looks like a page refresh and a blank browser window.
I'm trying to get the AS3 Flash remoting example found here: [URL]. and I keep getting this error: Code: Select allError #2044: Unhandled NetStatusEvent:. level=error, code=NetConnection.Call.BadVersion at amfphp1_fla::MainTimeline/frame1() Here's the code I'm trying:
I'm having trouble simulating a click call to a button(displayObject) thats generated via an API call( youtube as3 API). I have not seen any mention of security reasons as to why I can not simulate a click as long as something is registered with a click handler. Basically I checked to make sure the button made is listening to a mouse click event with:
trace(generatedButton.hasEventListener(MouseEvent.CLICK)) which returns true
I proceed to than call this:
generatedButton.dispatchEvent( new MouseEvent(MouseEvent.CLICK, true) );
And nothing happens yet if I physically click the button it works. Is there some security measure that prevents something from being fake clicked unless its origin is strictly from the system mouse?
I even set a timeout call on the click function and moved my cursor over the button and let it fire in case it was an issue of the mouse having to over the object but still nothing. I am kind of stumped at this point.
I have an enterFrame action that I use on a graphic:
[Code]....
Because I want to use the above code more than a few times, I tried to make it a function.
[Code]....
But for some reason the function call does not work when I call it via an action on a graphic where initially the code worked when it was explicitly written and not called as a function.
I need to get a javascript var in my Flash application. I like to be able to just set a variable in the javascript (client constraints) rather than define a function.
Can this be done? I am trying to use the ExternalInterface.call()
We have been given some code that does a URLRequest call which is really slow to respond, so I was looking to make it pull the data from the page, as it is already on the page.[code]I have tried to replace it with this (actionscript is definitely not my forte):[code]I am using addCallBack as that is what the editor suggested via autocomplete, unfortunately it doesn't seem to work. Unfortunately I cannot go back to the developer at this time.The error message is:Call to a possibly undefined method addCallback through a reference with static type flash.external:ExternalInterface
have a node that has an asfunction embedded - won't work. if I change the a href to a web page- it works fine. If I try to call a custom function it doesn't call it at all.
JS-to-AS3 callbacks work in kinda asynchronous way right? So for example if I ask SWF to download some file, which may take some time (depending on the size of that file), and while it downloads it, ask it to do some other operation (suppose SWF has several callbacks for various purposes), what happens in this case? Does SWF continue to download file and handle my second request in a different thread maybe, or it crashes, or throws some error? I know this is a good case for some testing, but I wonder if anyone has already done that, or maybe there is public info on the case that I cannot find?
I have an issue with my eventListeners with the URLLoader, but this issue happens in IE, not in FF.
public function getUploadURL():void { var request:URLRequest = new URLRequest(); request.url = getPath();[code]....
The issue is that my getBaseURL gets executed automatically after I have executed the code at least once, but that is the case only in IE. What happens is I call my getUploadURL, I make sure the server sends an event that will result in an Event.COMPLETE, so the getBaseURL gets executed, and the listener is removed. If I call the getUploadURL method and put the wrong path, I do not get an Event.COMPLETE but some other event, and getBaseURL should not be executed.
That is the correct behavior in FireFox. In IE, it looks like the load() method does not actually call the server, it jumps directly to the getBaseURL() for the Event.COMPLETE. I checked the willTrigger() and hasEventListener() on _loader before assigning the new URLLoader, and it turns out the event has been well removed.
I simplified my code. To sum up quickly: in FireFox it works well, but in IE, the first call will work but the second call won't really call the .load() method; it seems it uses the previously stored result from the first call.
