ActionScript 3.0 :: PHP To Flash Asynchronously
Jan 31, 2010
I have a Flash application that exchanges data with php scripts. Problem is, I can SEND updates, not receive.Example:
- user drags an object to another area
- flash sends this action to a php script using URLLoader
- the server acknowledges the action and returns an "ok" message with the same URLLoader
Now if the server wants to send a message, like "there's an update available", or "your friend has logged in", how is this supposed to happen?I believe an always-open socket is out of question, because the server will have to handle too many users at once and the section might be indefinitely long. I'm not so sure about the Flash client constantly pinging the server.So, what's the best way to send data from PHP to Flash asynchronously?

I'm starting a project that will build a flash file with quite complex capabilities. I expect the size of the swf/swc files will be quite big. In order not to slow down the page download, can I build the swf file so only immediately needed components are loaded with the page and other later-stage components can be silently loaded in the background?

I have a flex application that repeatedly polls a remote XML file to detect changes, but I've found that once the file hits a certain size, the poll blocks the UI and makes the page unresponsive for a short time.
Is there any way to ensure that the call made to the server or the event from the flash.utils.Timer class runs asynchronously to the main UI thread?

I am trying to write a class, which loads multiple images asynchronously. Can anyone help me to write a image loader class which loads multiple images. My doubt is that do i need to create different instances for Loader and URLRequest for each images? How this is managing efficiently.

I have a flex application that shows information gathered from different external services by using rest api. Some of them are resource intensive, take longer to response.

I have made an application which loads large pictures and videos (1920*1080 px).
- Picture component is a swf movie that I load with a Loader and feed him with the path of the picture I need
- Video component is a custom actionscript class that uses Video class.
Before to create any of these components, I display an animated sprite (a wheel to suggest a current loading). Then I create this component and load the content. When the content is loaded, then I add it to the display list and remove the wheel sprite.As these actions take a while, the wheel is visible for 1 to 2 seconds. My problem is that during this loading operation (by a Loader or Instantiation), the animated Sprite is not running properly and smoothly, like if Flash was loading the pictures and videos synchronously.Is there a way to make an animated sprite running properly while I am loading a swf or loading a video through the instantiation of a class, means running something asynchronously?

I'm working on implementing communication between an Adobe AIR app and a browser Flash object, and the LocalConnection documentation mentions an asyncError as a potential event:
asyncError: Dispatched when an exception is thrown asynchronously — that is, from native asynchronous code.
However, that's the only documentation I can find on it. Does anyone know what this error actually means? I've searched around but couldn't find any reference -- most sample code I found does an addEventListener() for the asyncError but doesn't give any clue as to what it means or when it could occur (i.e. if it could occur when sending or when recieving).The Adobe documentation page also lists potential events for each method, but asyncError isn't listed under any specific method, only for the general class.

I am adding data inside a VGroup dynamically using Action Script. Each data is an instance of a custom component. So when the number of item is more, It take time to load, which look bad.
Is there any way, we can load data to it, asynchronously or is there any way, so that more data can be added inside a scroller only when the scroll bar reaches to the end ( as it happens in Android or IPhone).?

Is it possible to delegate heavy computations to be handled asynchronously (on the user's machine)? When it's done, I could just fire an event, catch the new data, and update. I have played with this for lesser operations, by just setting up a que and only handle a few operations per frame; but is there another method? That feels like a heavy handed workaround, and it won't scale with faster/slower machines. IE: 12 operations per frame works fine on the test machine, but my machine can handle more, but won't do it because it's hard coded.

I'm working through Dreamweaver fairly well, and I'm now wanted to import Flash buttons I've created myself into Dreamweaver for a website I'm currently building, and it's here that I'm finding the problem. I have been to the 'get URL Function', but it says something about needing to link to a web page? But my problem is how can I link Flash Buttons to a web page, when my site is still being developed and not published? Do I have to publish first?

:confused:Does anybody know is Flash mx 2004 compatible with flash CS3 and flash 8?? I can not open flash cs3 on my laptop with flash mx2004 also can actionscript 3.0 be used with flash mx2004 and flash 8 because when I save my flash cs3 document as a flash 8 document it does not work? I am awful confused with all this. If you created a flash website in flash 8 or Flash mx2004 you can not open in in flash cs3 it dosent make sence?

Are there any programs or features in flash that can simplify flash vector art?
I just realized that one of the reasons why my program might be running so slow is that I made the images out of lots and lots of circles. When things didn't look right I often just put larger circles over smaller ones. I didn't think that flash might still be drawing the invisible circles underneath-

We've got a green screened video playing in a flash movie over top of our html content.when the movie ends, flash uses external interface .api to call a javascript function which swaps the flash movie out with a 5 x 5 pixel flash movie (rewrites the <div>).this works and you can interact with the html content after the flash movie in all browsers except firefox.anyone know of any work-arounds or is there a better way of handling flash over html in this fashion?

We are developing our app in flash/flex builder for the front end hitting .NET backend webservices. There is one section of the old app that will not be initially converted, so we need have it appear in an iFrame.
So far all that works fine.We shrink the size of the SWF in the host page to just be the menu/nav area. And underneat that I have an iframe control that loads in this page from the old site.Now the problem. in the SWF is a drop down list to enable picking a client. Since the SWF has been shrunk to about 100px high, the drop-down will only occupy within that 100px area which it's opened. This is NOT good as you can imagine. How can I make the drop-down list descend over-top of the IFRAME control and thus extend outside the SWF dimensions? Is this possible?
I tried to make the internal stage transparent and leave the SWF a little larger, about 400 px high, but the IFRAME still appears behind the SWF.

Is the Flash Video (or Flex VideoDisplay) component capable of seeking to an exact moment in a video?It seems to always 'snap' to keyframes (which is understandable). I'm just wondering if there are any mechanisms in the video classes for seeking to exact frames, ie it should do the translation from keyframe to specific frame in the background rather than having to actually play the video forward to the desired frame.This is not a streaming file and has nothing to do with buffering. The player is just downloading a movie file from the web and playing it from memory.

Situation: Got a flash object with an icon bar (div with pngs) on top of it. Works on all browsers except Firefox 3.6 on Ubuntu 8. Example: http://ListAndPlay.com
Problem: Icons suddenly disappear after the flash is being loaded. See this screenshot: http:[url]...What I've tried: Setting z-index, recoding the JQuery behind it, nothing works.

Good day to everyone. I'm here today to seek help about Flash CS4 and ActionScript 3.0. The story starts when one day, my boss asked me to make a flash presentation about their upcoming user training for a newly developed software. I was enthusiastic and excited about it because it's been a long time that I did not use Flash (note that I don't have any experience in ActionScript 3.0). At first, everything was a bit rough as I need to recall how to properly use the frames to create a successful animation. As I was about to finish the project, my boss approached me again and asked if I could insert a menu page in front so that the users won't have to replay the whole thing again just to look for a little something on that part of the movie. So yea, at first I was abit hesitant to accept. I said that it will work with Powerpoint. But she's a total pusher and I was forced to say yes. Now I'm having this problem about how to make a flash button load a swf movie.I've tried searching all over the net for tutorials but most of the times the "getUrl" and other stuff are said to be outdated.

I need to catch a hover event on top of a flash object, so I set the wmode and created an invisible div on top of it to attach the event listeners to. Thing is, I can't click the flash object. The cover is swallowing the clicks, and the things I've tried to go around this have made a mess of the hover events. This is the 30th problem I ran into in 2 days time and it's driving me crazy xD.

My website will have a logo on the header that will play as a flash movie (animated flash movie .swf). I am looking for code / algorithm that will display an image with the same dimensions as the flash movie if Flash is not installed or enabled for the current user accessing the site. How do I do this?

I have a flash file that loads in a external swf. That swf contains a form that I want to control the tab order on. The external swf has form fields in it, and I have their tab indexes set. When I hit tab, flash ignores the flash index, and focuses on some of the navigation elements of the parent .swf. What am I doing wrong?

Here's the site: [URL] From feedback I've gotten, it appears that under certain circumstances the first image in a set of images does not load properly, although I haven't seen it myself. I'm told this happens only in Firefox. And I believe only Flash player 8. Works fine with FF and Flash player 9, or IE with 8 or 9 I believe.
