We are in process of optimization of Flex AS3 Application.
One of my team member suggested us to make varible name length smaller to optimize the application performence.
i.e.var IsRegionSelected:Boolean = false; //Slower
var IsRS:Boolean = false; //faster
My question is, does a better, faster CPU necessarily equal faster SWF compile times? Or does it rely on something else (OS, memory, etc). I only use AS3 and some of my projects take a while to compile. If certain hardware can guarantee me a faster compile time, it'd be worth including those things in my shopping list.

i am making a flash application in which i have to save information in xml file. i am able to open a xml file,make changes but unable to save it. the app n xml file are in same folders in pc.
[code]in my original code..function "test" will change the x axis of the images by Timer..I wanna the x axis of the images can be changed after every two seconds..but when I run it..it's obvies faster and faster every time when the Timer dispatch the TimeEvent the delay always shorter than the last time.

View 3 RepliesI compile my Flex application with several swc's (libraries) and it creates a swf file. The sum of the swc's is roughly 4 MB yet the actual swf generated is only 1.6 MB. How is this possible?
View 3 RepliesI have a large xml passed from grails to flex. When flex receives the xml, it converts the xml into an associative array object. Given the large xml file, it takes too long to complete the loop, is there any way in flex to make conversion faster? Below is my sample code.

I made a Flex 4 web application. Upon testing locally, I already got satisfied at how it looks like. However, the swf's file size grew to around 6mb in size so when I uploaded it to my website and viewed it, it takes forever to load on a computer with quite slow internet connection. So my question is, how do I make it load faster? Should I:
separate it into chunks? If so how do I do it.
not put the embedded images inside the SWF but instead, store it outside in a folder? If so, how do I make it load on the background while the user is interacting with the primarily loaded parts of the web app?
I have a C++ application which sends images to a Flex/Air front-end via TCP sockets. All this data transfer occur in the same host, so the socket connects to a localhost server. The problem is that the Flex/Air takes a really long time to read the entire image from the socket. The server sends the image quite fast, but the Flex/Air reads this image in tiny parts. The whole image has about 300MB and the Flex/AIR reads only about 1KB each iteration. So the flex keeps calling the socket data callback, which is causing the application to slowdown.
Is there any synchronous sockets to use with flex, or some kind of socket which can read the entire data all at once? If sockets aren't the best choice, is there any other faster options? My socket class looks like this:

I've heard somewhere that LCDS is no longer baked in into CF9, and LCDS Express will be phased out, is that true?
If I were to start a new CF8.01 + LCDS Express 2.6 project, what are the risks? Should I abandon that plan and go for BlazeDS instead?
what's the easiest way to cut string in Flex ?I mean, I have a sequence of urls, I want them at most 60 characters length. If they are longer they should be cut and "..." should be added at the end.
<mx:LinkButton label="{bookmarksRepeater.currentItem.name}" click="navigateToURL(new URLRequest(event.currentTarget.label.toString()))" />
So is
public var user:Object = {};
user["firstName"] = "Bill";
user["lastName"] = "Cosby";
Slower than if I have a value object like User?
var user:User = new User();
user.firstName = "Bill";
user.lastName = "Cosby";
I've got a small action-script chart, that's meant to be live updating, and also be able to support more than 10000 points of data. The way it's currently set up it doesn't need to redraw the whole chart if the new line we wish to add doesn't extend that chart's boundaries. Yet it does, the redraw regions show the whole chart as being redrawn as opposed to the single line i need to add. When the chart gets a new piece of data from the javascript it does the following.(some stuff has been stripped for clarity.[code] Is there any better way to do that, that won't redraw the whole screen? Is my coding pattern wrong for this type of update?
View 1 RepliesI am having a problem with my build. When I add a valid statement to the code it will no longer complie and it fails with errors from an unrelated file.I experience these issues building with ant or building with mxmlc on the command line.Adding a valid statement to an myLittleBox.mxml will cause this error.All the errors are in ViewerMain.mxml.This file is not the main mxml file but it is referenced from the main mxml file.Before changing myLittleBox.mxml ViewerMain.mxml had no compile errors.There are no errors related to myLittleBox.mxml myLittleBox. mxml has no references to ViewerMain and only uses spark components ViewerMain.mxml has no direct references to myLittleBox.mxml. Its children's children's children would have a reference to myLittleBox.mxml.The valid statement added to myLittleBox.mxml could be many things (they all break it) including a comment.[code]
I noticed that the Model was using a constant in Viewer 1.This was causing all of Viewer 1 to be built when Viewer 2 is built.I moved the constant from Viewer 1 to the the Model (where it really should have been anyways) and my project built successfully since Viewer 1 and Viewer 2 were not being built at the same time.It makes sense that this would resolve the issue however this is just resolving a symptom of the issue.I am still very curious what was causing the the compiler to fail on ViewerMain.mxml when I add a comment to myLittleBox.mxml.I guess that it will remain a mystery for now.
I'm pretty new to Flex. Basically, anything I try to build with mxmlc fails to run now, giving me the above three errors depending on what I do. It was working 30 minutes ago, I've been spending that time trying to figure out what has changed. I redownloaded the Flex SDK, cleared my assetcache, have cleared Firefox's cache. (I'm using Linux.) Even if I compile with -static-link-runtime-shared-libraries=false, since it seems like #2048 is a RSL problem, it still refuses to run.
Another strange thing, if I keep
<policy-file-url>[URL]>
<rsl-url>textLayout_1.0.0.595.swz</rsl-url>
In my flex-config file, then firebug tells me that my swf file is trying to access a copy of that in the app's folder, giving error 2032. And if I stick the one I have in frameworks/rsls/ then it gives me error 2046. I don't know how it could not be properly signed, unless Adobe magically changed a signature and didn't update their flex SDK.
Given a dynamic or non-dynamic class like the following:
package {
public class MyClass {
public var myProperty:String;
public var myBooleanProperty:Boolean;
public function MyClass() {}
}}
Flex 3 allows you to assign a value to myProperty like this:
myClassInstance["myProperty"] = "myValue";
myClassInstance["myBooleanProperty"] = true;
I regularly parse XML to get property names and their values then update correlated classes using this technique; however, Flex 4 no longer allows assigning the boolean property. I don't have a work-around.
If you trace the results:
trace(myClassInstance.myProperty) // Returns "myValue"
trace(myClassInstance.myBooleanProperty) // Returns null
I am using Flash Builder Buritto with the latest "nightly" Flex 4.5 SDK, build 17689. It seems the dropShadowEnabled property is no longer supported with the Hero default skin. I get this compilation error:
The style 'dropShadowVisible' is only supported by type 'spark.components.Panel' with the theme(s) 'spark'.
Is there any way to disable the shadow without making a custom panel skin?
I have a custom component I've developed that's part of a dashboard.It does some polling based on a timer that's part of the component.
When the user navigates away from the view that contains this component I would like to stop the timer and hence stop the polling.I can obviously fire an event when the view's changed and catch it within the component but I was hoping that there might be a way to contain this all within the component.Is there an event or state change within a component that triggers and even when a component is currently be displayed?

I have seen a few blog entries on this and have had a discussion or two with my team mates but I would like to see what the stack overflow community thinks.
So why does the Adobe Alchemy Tool create so much faster running flash byte code than the flex compiler?
Also, when will the flex compiler be able to make similar performance gains? Will it require programmer specific use of special Array's or something of that nature to get the same performance?
We've got an Illustrator file with something over 1,000 layers. We're trying to import this into Flash and keep the layer names intact, such that they become the names of the movie clips that are imported for each layer and can be used programmatically. (It is a diagram and arrows, boxes, etc all have callout names that will eventually allow them to link to a database.)As near as I can tell, the Import dialog will NOT pass this info across between the two parts of the dialog.
View 1 RepliesI started a thread about a reference to a symbol House, in the output window, which was: House_1. A lot of people said some useful things about that. All day I've been thinking about it, and I came to the conclusion that I don't understand things, at a very basic level.
Consider:I make a movieclip which I give the Symbol name Drawer. (I don't export it for AcitonScript.)On the stage I manually place two instances of this Symbol. The first one I give the Instance Name drawer (in the properties panel). The second one I leave nameless.Now if I trace the names of both these clips, by
trace(this.getChildAt(0).name);
trace(this.getChildAt(1).name);
the output window gives me
drawer
instance2
Now I know that the so-called "instance name" which I gave in the Properties Panel (drawer) is, in reality, a variable name which Flash gives my first instance behind the scenes. And instance2 is a name that Flash gives my second instance. What exactly the nature of that name is, I do not know.My point is: both names (drawer and instance2) are the .name property of these movieclips. Otherwise I could not have traced them through asking for the .name property, in the above. Yet only the first of these two can be manipulated:
drawer.x can be set;
instance2.x can (as we know) not be set.
But...why? What is the real difference between these two kinds of names? How can they both be the .name property of their underlying movieclip, yet be of such a different nature? What IS the nature of the instance2 name? If it's a String, how come the .name property of one movieclip can be a variable name, while the .name property of another (but identical) movieclip is a String?
I've searched every bit of web page on the net I could find. But it looks as if nobody addresses this issue. We all just work with it - but it makes no bloody sense. A name property = a name property, you'd think. Whether Flash set it or I set it should not make a difference. The x property of a clip, for example, does not change in nature according to who set it - me or Flash.So, again, just to emphasize the problem: how can a property (the name property) of a movieclip change in NATURE depending on who set it? After it's been set, shouldn't the name property of a clip be of exactly the same nature as the name property of another clip?
I am trying to get the child XML tag names in my AS3 program. For example, I have a file with information like this:
<LocationInfo>
<City>New York City</City>
<State>NY</State>
<Zip>10098</Zip>
</LocationInfo>
I load the file into an ArrayCollection and can access each item I need by name such as
["City"] // Returns New York
Instead of getting the value, what I am trying to do is get the tag name such as State or Zip instead of NY or 10098.
I have a C# web service that returns a DataSet with multiple DataTables. It's easy enough to get at the data using this web service event handler in Flex:
static public function getData_Handler(event:ResultEvent):void {
for each(var table:Object in event.result.Tables) {
// ...
}}
How can I access the name of each DataTable from Flex? When debugging, it's clear that each DataTable's name gets mapped to a property on the event.result.Tables object, but I don't see a programmatic way to get a string representation of the name.
Flex has an issue with hyphens in xml. I need to generate an xml object with hyphens in the attribute for a Google Checkout implementation.
I can get away with:
var xml:XML = <item-description/>;
and
var xml:XML = <item-description the-name="foo"/>;
but what I need to do is set the value of an attribute like this:
var timestamp:String = methodToGetMyTimestampString();
var xml:XML = <item-desc/>;
xml@start-date = timestamp;
but I can't do that. Since flex doesn't like the hyphens, I don't know how to get or set attributes with hyphens in the name.
Let's say I have a class which looks like this :
public class MyClass
{
public var attribute1;
public var attribute2;
}
and I'd like to get attribute1 and attribute2 as strings. I tried this :
var test:MyClass = new MyClass();
for (var key:String in test)
{
trace(test[key]);
}
but it does not work, it never goes in the loop. How can I do what I want to do ?
If you try to add an object out of an linkagename in Flex you get errors. Like:1180: Call to a possibly undefined method [linkage name].If I don't want to create classes for every library symbol I'd like to add, is there any other way/praxis of doing this besides using 'getDefinitionByName', so that I won't get errors in Flex?
View 7 RepliesCurrently I work on localization for a Flex application. From an article I know that you can control the localization with the following FlashVars:

I would like to make an Object that has key names taken from a variable. Probably this is not clear enough, so let me make an example.
I have two variables var str1:String = 'firstKey'; and str2:String = 'secondKey';
How can I make an object that would look like:
var obj:Object = {firstKey: 'some value', secondKey: 'some other value'}, note that firstKey and secondKey are values of variables str1 and str2.
Doing obj = {str1: 'some value', str2: 'some other value'} does not yield a result that I would like
