ActionScript 3.0 :: Monitor Browser Tabs With LocalConnection And Sense When A User Closes A Tab
Jun 28, 2009
In my application the browser window connect with long polling(comet) with the server. If the user open several browser tabs, only one of them(called the master) communicate with the server and serves as a proxy for the other tabs. I want to use flash localConnection to exchange data between the tabs. What happens when a user closes the master tab that holds the comet session? I can use javascript with the unload event to inform the other tabs that the master tab is closing and then close the localConnection but the unload event is unreliable. I can use polling to monitor the master tab connection object but it sound dirty.
When the master is closed one of the other tabs need to become the master. How do I make sure only one of them tries to become the master? If a user close the tab without flash being able to close the localConnection, will it cause a memory leak?

Can you call a function when the user closes the browser window or navigates away from the page? I'm making a cartoon, and I'm curious how long people watch it before closing the window or navigating away from the page. I could have it, every x seconds, report back the the server, and I can get a rough idea of how long they watched, but if it could report the exact time when the user closed it, I would know exactly.

For example, Lets say I have a flash swf game, and when users press connect they are assigned a random id that's then put into a mysql table. Then I have other users that connect and then can connect to these random ids. When users click disconnect i have the id taken out of the table that way when other people want to connect they dont get ids that arent active. is it possible that when a window is closed to have it run a php script? so i can get it to clear their user id?

im creating a presentation that has a bunch of links to websites and pdf files. right now the presentation opens fullscreen when first opened but if the user clicks one of the pdf or web links the clip minimizes and if the user tries to maximize the flash window the menu bar at the top is visible and cuts off some of the content.
is it possible to detect when the user tabs away from the presentation so the clip will pause automatically and i can tell the user to click to continue? i know this code will work fscommand ("fullscreen", "true"); that will make the presentation fullscreen again but i need the movie to pause if the user clicks a link. i have seen this before in games where the game will pause if i tab to another program and i have to click to continue.

I'm trying to build accessibility into a slideshow that will work in Window Eyes on a PC/IE7. The user will tab in order over a button for each slide. It all works except for I'd like to show the image on the stage when they tab to the button. I thought if I could listen for the tab, I could execute a function to change the image. But that doesn't seem to work. Should I scan for a change in which button is focused on? I'm not sure how to do that..

I'm building an online app which opens a SharedObject at its onset to do various things, one being remember whether a user has performed a certain action(vote) before because he/she is only permitted to perform this action once. This is all working fine, until our users began opening a new tab before voting.
If the user opens a new tab, and open the same application, this app(tab 2) needs to know if subsequently the user votes in tab 1. I thought this would be straightforward to resolve. However - for some reason, the sharedObject in tab 2 does not seem to update with updates in tab 1... if you were to refresh tab 2, it would have the updates, but while it is open, the data in the sharedobject does not seem to update.
It all works fine in general, the only time it doesn't is when there are two instances of a flash object open at the same time using the shared object. Maybe this is expected behaviour, and two flash objects can not use the same local sharedObject? It's hard to find this info in the livedocs.
This is the sort of code I am using to manage the SharedObject: (I know the first question anyone will have is, are you the flushing the object after setting your variable, the answer is yes!)
// i call this function at the beginning of the app
public function init(sharedObjectName:String):void
{
sharedObject = SharedObject.getLocal(sharedObjectName,"/");

I have an RTMP stream loading and would like to know the drop off time of the video. Is there a method of knowing when a person abruptly leaves the video session by closing the window, back button, address bar, etc?Or do i need to make an external interface call from JavaScript to Flash using something like onunload & onbeforeunload events?I am guessing that it is the later, but wanted to see if there was a method of keeping all my code inside of AS3.

Is it posible to make a flash site, which will change the size when the vistors resolution is diferent? Practicly, every visitor will see the same size of the site, even if he has 800x600 or 1280x1024??Maybe making html go fullscreen but make the swf occupy only 80% of the screen, so it always have the same proportion to the users monitors.Do you have any example?

I have found solution for my previous problem:
onClipEvent (load) {
_root.hitz = 0;
this._alpha = 0;
[Code]....
but now I have a new one! After fifth click browser keeps opening hundreds of new tabs! I think it's because flash keeps playing movie. There must be some kind of loop and every loop flash opens new tab. I tried to add stop(); in few different places but still no result.

I have a ColdFusion function which sends analytics called from a Flex sendPageAnalytics() function to a SQL database when the user navigates - this works perfectly.What I am trying to do is have the Flex application send a bunch of analytics when the user closes their browser, therefore providing information about the last navigation.
I have used an ExternalInterface callback and listener for window.onbeforeunload and a trace statement tells me that this is working fine.My problem is that when all bundled together, I get as far as tracing out that the sendPageAnalytics() function has been called, but I do not get a sendPageAnalyticsFaultHandler() trace or a sendPageAnalyticsResultHandler() trace, which I do on every other sendPageAnalytics() call.

My webpage loads a background flash which will connect to the server using socket. If a user open multiple windows/tabs of my website, the server will get multiple socket connections. Any idea of how to make sure that only one socket is connected from the same user and same browser?
I am thinking of using Javascript to monitor the window close event, if a window that was connected to the server is closed, one of the other windows will try to connect to the server. But I can't find a way to listen to that event.I was thinking of Flash's LocalConnection too, but can't find a way to assign unique connection names and let other Flashes know.

Really puzzled by the flaky behavior of LocalConnection. Using a debug utility(LuminicBox) that uses localConnection to work.
When the page containing the swf is loaded in a browser locally , localConnection works.
When the identical page and swf are viewed 'live' on a remote site, localConnection fails.

I'm noticing some unexpected behavior. Some time in the last few months, a change in either Firefox, the Flash player, or both, has made it so that Flash movies that are in inactive browser tabs no longer execute in real time. They appear to still execute, but only in bursts, and not in a predictable way. This is a problem because I develop a Flash-based (Actionscript 2.0, Flash CS3) multiplayer game that maintains a network connection and allows players to chat, etc.

The first one (FLEX application) sends a message on a dedicated LocalConnection to a second one (Flash application). The Flash then answers by sending a message on another dedicated LocalConnection. This message is not directly received by the FLEX and the delay is at least 30s, up to 1 or 2 minutes! It seems the issue only occurs with Flash Player >= 10 and it never occurs with Chrome.
I didn't find anything on the web concerning a similar issue nor something in Flash Player release notes. Did someone already have this kind of problem?
By the way, is there any tool that can be used to sniffer LocalConnection communications?
Additional information:
swf are located in different frames swf are embed with swfobject I tried to delay the Flash sending, I tried to create another LocalConnection dedicated to this call but I always had same result: for all calls, the FLEX method is called after the same delay. I also put a timer in FLEX to periodically log to see if there is no background process delaying the method processing but everything seems fine

I have been updating my flash pages, and so many people cant see the changes, because they have to reset their cache in the browser .. which is fine for any savvy internet user .. but there's a lot o folks out there who dont recognise this action .. are there any tips to talk to the browser that changes have been made?

i have a question that is almost like other questions but with a small but very important difference. how can i restrict file types for user with a popup showed in the browser.
The standard file input of html can limit that with a command but it does not work in all browser so it is not an option. I do not want to validate the file extension after the user has chosen a file but before that, when he is choosing.[URL].. but it uploads the file after the user has chosen it, i do not want to do that, i want to upload it after the user submits the form.
So the problem looks like this that there are some ways of not letting the user send a not valid file but they are not good because, one is that i validate after the user have chosen the file and the other is that i upload the file before the user submits the form.
I just want a simple thing to not letting to "chose" a not valid file, it does not matter if it will be made with java script or flash, just let it work.

As far as my understanding goes Modules kann be used to split an Application into different parts. A big advantage seems to be to be able to load Module after Application Start, to get a better Startup performance. I personally would like Modules to make me able to have an own Code Sandbox for the Module Code. So neither the Main App Code nor the Module Code should influence each other. But for examples CSS Styles from modules influence the Main Application an visa vers. My Question:
1. What can I use Modules for beside Runtimeloading ?
2. Are there options to run code in an own sandbox ? For Example via Loading swf assets ?

I have flash component in a website, which shows a preview. There are some UI components overlaid on the preview to allow navigation. Unfortunately it seems that in Safari on Macs, there is a problem:When the user zooms in or out (using the browser based page zoom), my overlaid UI items disappear for some reason. This does not happen on any other platform.I would have though that this zoom function would be something that is taken care of solely by the browser/Flash plugin, however, perhaps there is something I can do to force a 'redraw'?

Flex appears to have 2 video classes: Video and VideoDisplay. My question is when does it make sense to use one or the other?
What I can tell from initial glancing is that VideoDisplay responds to mouse events because it inherits from IntaractiveObject, but I'm not sure if it's a real difference, because Video seems to have a workaround for this in that you can add your own event listeners.
There's probably more to it, but this is the only difference I can see now. So my question for those who used these objects extensively, can you share your experience when you use one over the other.

I'm looking for a way to make a simplified version of the HTC Sense Homescreen slider. I had something like this in mind: [code]I basically need to make 8 homescreens. Each homescreen is an interaktive movieclip. Nothing fancy is going to happen inside those movieclips.No navigation buttons, just a plain and simple drag and slide with movieclips.I have a bit knowledge using greensock tweens also - so if you got a solution with this please share your knowledge.
