I'm using Flash Builder 4.6. As a simple example, say I have the following application:
<?xml version="1.0" encoding="utf-8"?>

I am running flex with BlazeDS. My backend is in Java.
I have the following function in actionscript:
override public function execute():void
{
super.execute();
var responder:CallResponder = new CallResponder();
[Code].....
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.
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

I have an actionscript function which is supposed to launch a panel and then fill in Networktopology data inside it.As, network data is too large that it consumes much time and makes browser hang!Even I tried to display busy cursor which also stopped spinning when data was being processed.How can I ensure processing large amount of data does not hang the browser.
View 3 RepliesA groups of friends are working on a little game that would listen to the microphone as part of the interaction. We've tinkered with processing and flex. What we'd like to know is if anyone has succeeded in:
recording from the microphone using a web app
performing an FFT on this microphone data
In the case of flex, according to the docs "Because sound data from a microphone...do not pass through the global SoundMixer object, the SoundMixer.computeSpectrum() method will not return data from those sources."[1]

I want to extend AdvancedDataGrid to show a Waterfall Chart in one of its columns.
To do that I already created custom cell render that shows bars as I need.
Now I have a little challenge: I have to pre-process data to show my Waterfall Chart properly. I have to do it before my grid is show. So, I assume that I have to extends AdvancedDataGrid and overwrite some methods.
I've been working with a 3rd-party multiplayer engine for a game I'm developing. A lot of messages get sent during certain times (loading, etc) to the point where it is possible that multiple messages may be sent per gameloop. To solve this problem, I am attempting to create a delayed message processing scheme. this function is invoked every time a new message is received:
Code:
// called by the Client
public function PushMessage(gameMsg:GameMessage):void
{
messageQueue.push(gameMsg);
}
And at a point in the gameloop, I want to process these messages and clear the message queue. The only problem: there is no assurance that the messageQueue won't be modified during that time. The messages in AS3 are basically interrupts (possibly overlapping), and I can't find any way to temporarily disable event dispatching for a specific EventDispatcher-derived class.
So at this point I can think of only two options. The first is to write a mutex using a Boolean and setTimeout. I do not want to do this for obvious reasons (bad! BAD!). The second is to give up on a delayed processing model.
Is there a way to process a picture > 4096 x 4096 px in pixel bender? Or any other technique?

View 1 RepliesI'm creating some image uploader in Flex with client-side image processing. Processing consists of two steps:
1. Resizing (solved)
2. Converting resized image (represented by ByteArray in PNG32 with alpha-channel) to gray-scale PNG with bit-depth = 2 and no color-palette. Is there any existing library that is capable of second step? Something like libpng for C++, maybe?Edit:It seem I stumbled upon rarely encountered problem. However my descision was to create an AS3 class that is capable of converting bitmapData to 2bit grayscale PNG. I used standart PNGEncoder and PNG format specification (which is not so good as I expected) as basis.
When I test my deployed app in a browser the popup window continues to be displayed even after it should be closed. Everything works as expected when debugged in Flash Builder 4.
Following is currently what's happening: the request is sent to my restful web service, which processes the request, (seemingly) the ResultEvent is called which in turn dispatches the profileEvt dynamic event that changes the view state. However, the popup window does not get closed and the applet gets 'stuck.'
Below are the flex applet web service event listeners/handlers:
webService.addEventListener(ResultEvent.RESULT, function(event:ResultEvent):void
{
var rawData:String = String(event.result);
var profileEvt:DynamicEvent = new DynamicEvent("profileSaved", true);

The following is my codes. This is still work in progress; so, you will see some functions with empty contents. Plus, this is my first Flex application; please bear with me. This is a quiz application that gets the questions and answers to each questions from a ColdFusion web service. There are three types of questions, True or False, Multiple Choice with single selection, and Multiple Choice with multiple selections. So, based upon the question type, the application would dynamically generate the appropriate amount of radio buttons or check boxes for the users to select. I got these working. The problem that I am having is, I am not sure how to check what the users have actually selected. In some other forums and posts on other web site, it said that I can use event.currentTarget.selectedValue to get the user selection. But when I actually do it, I got a run-time error saying, "Property selectedValue not found on mx.controls.FormItem and there is no default value." My question is, what do I need to do to capture the user selections?

The XML file is formatted like this:[code]The traces are all for debug purposes.If I place this code into the actions panel of the first frame of the flash document (without the thisObj:TriviaGame = this part), everything works fine and I get correct traces.If I place this code within TriviaGame.as, all of the traces print 'undefined', but it claims to have opened the file correctly.I've found a lot of XML tutorials on this site, but none of them seem to deal with processing XML from within a class file--they all put the code directly on the frame.

How can I make this change to the XML dynamically in Actionscript 3? Without changing the file directly.
PS: I have another XML (theme.xml), where the problem is to have repeat the same node name, identical in everything, for example:

I've got a function that loads an XML file, and processes it into an array. Outside the function, if I trace for any of the contents of the array, it comes back undefined. What I've noticed is that the trace command is triggered before the array has been populated, even though the function to populate the array is called prior to the trace command.Here's the code:
Code:
var playListArray = new Array();
var myXML:XML = new XML();
myXML.ignoreWhite=true;[code]......

View 11 RepliesI've been using Processing for around two years now, and I really like it. However, I feel like Flash is a bit more useful for coding games, as it's more universal and flexible. I'm starting to feel like I have no idea what I'm doing, and I really don't get any of the concepts like movie clips and the stage and so forth. In Processing, to make, say, a ball, I might make this:
Ball[] ballArray = new Ball[ 0 ]; //Array to store each ball in
void setup()
{
size( 400, 400 );
[code].....
And that would let me create as many instances as I like, anywhere I like.I haven't the faintest clue how to make a comparable applet in Flash.I've tried making a 'ball' class in a separate .as file, but it gives me an error about too many arguments. I also don't know how to draw a shape directly to the screen.
I have researched this topic and I believe the answer is AS3 Scope Issue though I can not resolve the issue.My xml loads fine and I can traverse it fine. I need to compare it against an array in another file so I believe the best thing to do is put then node I want into a class variable/field.
My xml:

I am slugging through the processing of data posted from an Flash based form. I have a dev server that uses php to process input. The php script produces the following test php file variable array:
$input['VE'] = 't';
$input['A'] = 't';
$input['ML'] = '5.1';
$input['SA'] = 't';
$input['SV'] = 't';

What do all the variables sent to the server mean in this context? And, is there a tutorial focusing on form handling with Actionscript 3.0?
I'm making a 3D program and I've already made the back end which calculates where each object's polygons should be. However, I can't seem to find a quick way of drawing them without having to remove and redraw them each time, which I'm sure would take a lot of processing power, knowing the way that Flash does things. So is there a way to draw a shape (a quad in this example) and then alter the shape's color and the position of all of its corners in the next frame without taking a huge load of processing power? I would really like to be able to do this to at least 20 polygons, hopefully more, within the span of one frame at 20 fps.
View 3 RepliesI'm working on a Flash intro for a site. After the Flash movie plays I want it to wait three seconds and then send them to the index page. Currently I'm using the action script:

I've got that keyed to the last frame. The issue is at the end of the Flash movie it displays the company logo image. Well with that script added to the last frame it just quickly blips up the logo then takes you to the main page so fast you don't even get to really see the logo. I want the viewer to have a couple seconds to take it in, but then move them along to the main site without them having to look for a button to press.
