ActionScript 3.0 :: Turning Asynchronous Calls To Synchronous?
Aug 27, 2008Is there a way to have a synchronous call to a URL to retrieve the HTML code? If not, is it possible to turn an asynchronous call into a synchronous one using some trick? I can't believe Adobe wouldn't implement this option. I tried looping until the result is back but then the status function never fires making my loop infinite.

I'm a ColdFusion developer and recently started working on a project in Flex. I am getting more and more frustrated with AS and Flex lately. It seems that whatever I'm trying to do is either really hard or impossible while it usually can be done with one line of code in ColdFusion. I'm still learning these languages and I'm sure my lack of knowledge is the reason but for some reason I can't get ahead with my project. It looks like the learning curve is much steeper than it should be.

Anyways, here's my code for testing this functionality. The main application file looks like this:
Code:
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" applicationComplete="init()">
<mx:Script>
[code]....
This works OK except the function returns false before the HTTP call returns its result. If I un-comment the while loop the onStatus function will never be called and therefore end up with an infinite loop. Not sure why this happens.
Flex :: RemoteObject Synchronous Call?
Oct 1, 2009In the code below when I call chkAuthentication function from another function the remoteObj.login (login function in my service file (.php)) is called after the remaining code in that function. i.e., the loginStatus is returned from the function before the result-handler function loginResult is called. but my loginStatus is supposed to be set in loginResult function. It seems that the asynchronous behaviour is the culprit. what should I do in order to get the loginResult function to complete first?

View 1 RepliesFlash - How To Make Synchronous URL Requests From AS
Sep 13, 2010I have a big loop in actionscript that sends lots of data to an url:
for(var i=0;i<1000;i++) {
var request:URLRequest = new URLRequest();
request.url = url;
request.method = URLRequestMethod.POST;
request.data = data;
var loader:URLLoader = new URLLoader();
loader.load(request);
}
The problem is because URLLoader can make only asynchronous calls, it sends all those thousands requests at once which kills webserver. Also it acts a bit strange on top of that. Lets say the loop is running for 5 minutes. For whole 5 minutes there is no requests coming to web server, then at the end they all are sent at once. I already tried everything I could possibly think of (empty loops, callbacks, delays) - nothing works. All requests are sent at once no matter what. How to make requests synchronous, so it will send one request after another?

View 5 RepliesFlex :: Programming Synchronous Web Service Calls
Aug 19, 2009Web service calls are asynchronous in flex, but I wanted to wrap a web service call in a class to provide synchronous encapsulation. Something like the below - the user could call getMyMethodResult and get the result returned by the web service. I expected the thread that recieved the soap response would populate the variable _result and mean that getMyMethod would, after a time, find _result is not longer null. But it doesn't! Can anyone explain why this does not work?[code]

Jun 22, 2011I have small Flex web based util with single button.

ActionScript 3.0 :: Asynchronous Image Loading?

This was easy enough to code with an ENTER_FRAME event handler and a few state variables.Here are the most relevant snippets:

View 2 RepliesFlash :: ActionScript 3 Handle Asynchronous Callbacks?
Jul 11, 2011I have a piece of code in my game which looks a lot like this: MultiplayerAPI.createGameRoom(function(){ successFunction(new Object()); }); Basically, the createGameRoom is performed and, upon success, the function I passed is run. However I've been running into some strange bugs recently and I'm wondering, is the instance of "new Object();" the same each time the callback function is run? It needs to be a different, fresh instance of Object each time, but I'm having some garbage collection issues which make me think it's passing the same object each time that event callback is fired,

ActionScript 3.0 :: Checking Against Multiple Asynchronous Conditions?
Feb 1, 2010If I have one parent class that instantiates 5-10 different child classes, each of which need to load multiple assets etc, how can I check within that parent class to make sure all of the 5-10 children are loaded & ready to go before telling the program to continue?
The tricky part is that the exact number of those 5-10 classes that are instantiated is determined at runtime, so I can never be certain which I should be waiting on and which not to be waiting on. And just to be clear, these are different modules of sorts, not multiple instances of the same exact class.
Media Server :: Recording Of Video And Audio Is Asynchronous
Oct 15, 2010I'm currently able to record audio and video (from a webcam) to a Flash Media Server. However, in some cases users have a webcam with no builtin
microphone. In that case the flash client uses the default microphone with 'Microphone.getMicrophone();' and possibly selects the micrphone of the PC.
A delay between audio and video is caused in cases with a separated webcam and microphone. There isn't a lot of delay on an internal network (e.g. LAN) however, there is a very large delay between audio and video on an external network (e.g. WAN).
Flex :: Create A Web Server For Asynchronous Request From A Air Client?
Dec 21, 2009I have created a client with Flex Builder which works in a browser but also in an Air windowed application. I must connect it to a server and it has to do asynchronous request related to changing data of the server.Because of the too much expensive cost of LiveCycleDS license, I was looking for other ways, maybe open source and i found the following solutions:
Adobe BlazeDS
Granite Data Services
WebORB Community Edition
I want to ask you which is the easy way to create the solution described above, expecially i want to use J2EE application server type.
Flex :: Multiple Asynchronous Calls To Populate An Object?
Aug 28, 2010I'm developing a Flex application and am having some trouble working with asynchronous calls. This is what I would like to be able do:

Flex :: 4 - Download Files - Make The Save Asynchronous From The Dialog
Jan 15, 2012I want to download a file in flex. Here is my desired flow User clicks "view" Code goes to backend and get the file as an array of bytes bytes sent from java to flex via a callback flex then opens dialog and user decides where to save the file Unfortunately the last part is not on a user event but on the callback from the server. When I call new FileReference().save(...) it tells me this. An alternative could be
User clicks "view" Flex shows user the dialog and user chooses where to save file Flex goes to backend requesting bytes of file bytes sent to flex and data is saved. For this approach I am unsure how I can make the save asynchronous from the dialog. I want the user to save a file but the data but come from an array of bytes from the backend
