Actionscript 3 :: Flash Application Cleanup On Unload From Browser
Nov 15, 2011
Generally when you unload an swf from another swf you would follow a cleanup utilzing removed from stage or unload events. But when you exit an as3 flash application by either navigating away from page or reloading the page or closing/removing the application. what is the best practices you would follow to ensure proper cleanup and garbage collection.
Question : what methods in solely as3 code can be used in this regard. It may be argued that once an swf is unloaded or removed its memory foot print can be verified to have decreased eg via the task manager Is this a good enough measure? Or is it advisable to handle the unloading/exiting in a proper manner ?
I create some elements( UIComponents, mainly Panels) inside the "mx:Application name=tst . I need to cleanup all those UIComponent's on MouseClick event , using Actionscript. Is there any way I access the children elements of mx:Application ( I used var totalChildren:Number = this['tst'].numChildren ; but looks like it fails to access the children list).
I have a Flex client application. I need a clean up function to run in Flex when the user closes the browser. I found the following solution on the net, but it only works half-way for me. How could I fix it?CustomEvent triggered, but not executed. >> EventHandler for CustomEvent.SEND_EVENTS is defined by a Mate EventMap. All the handler does is to call an HTTPServiceInvoker. In debug console, I'm able to see the handler and HTTPServiceInvoker being triggered, but neither the resultHandlers nor the faultHandlers were called. I know this event handler has no problem because when I dispatch the same CustomEvent.SEND_EVENTS in a button click handler, it behaves exactly as I expected)Browser seems to wait for cleanUp function to complete before it closes. (all traces were printed before browser closes down)
Code I added the following into the index.template.html window.onbeforeunload = clean_up;
If I call the play() function of a Sound, which returns a SoundChannel object, will the SoundChannel still linger around after the sound clip is finished playing and eat up resources? Or will Flash's garbage collection scoop it up?
I'm developing a Application in Flash Builder 4.5 to control an server application, also not a classical Website. All is Spark and I set the minHeight and minWidth-Properties for the , because i have an Image and Navigators, and there becomes a strange effect, when the browserwindow is sliding smaller that the min-Properties.The content and there scrollbars are already controlled over the parent containers, thats not the probelm.
Summary: What i expect from a upToDate-Application is:When the Browserwindow is larger than the min-Properties, but too small for the content, the Application respectively the container should control the scroll bars.If is the Browser-Window smaller than the min-Properties, i expecting scollbars from the browser. I think, in this case, the html-wrapper needs knowledge about the min-properties.
I'd really prefer my actionscript 3 project to launch in a debugger window outside of a browser, but it always opens into a browser. I browsed through the preferences
I need some little 3D rendering in my browser application. Unfortunatly the Internet Explorer 8 is not going to support WebGL, Canvas 2D or SVG. And the Windows XP users can't install the IE9 (which supports at least Canvas 2D). What do you think about Plugin-based alternatives?
I mean Silverlight with XNA 3D seems not to be supported any longer.Flash has a bad reputation if I ask Apple. What do you think about Unity3D?Are there others?
[URL] I needed to do clean up before the MC is gone ... so after some digging I found this event:
Event.REMOVED_FROM_STAGE
So I am trying to ask for some conformation here: Is this the ONLY situation that my MC will be deleted automatically by Flash? If so then I can just listen to this even and call my cleanup function when it happens...
Is there a way to launch an Adobe Air Application from the browser? I am developing an application that uses webcam, and when the user enter on my site, I need to start this adobe air application installed on the user computer.
my organization is in the process of building a touchscreen interactive kiosk. We've designed a flash application to run on the kiosk to display information about our business, our publications, etc. We'd also like to be able to access our website through the flash application. We're having trouble figuring out how to do that effectively. The best we can do is to have the application launch Internet Explorer in a seperate window. This isn't so bad if we run IE in kiosk mode, however it becomes difficult/impossible to navigate back to the flash application (or to close the browser) without a mouse and keyboard (which users won't have access to).Wondering if there's a way to open or access a browser inside of the actual flash application, so users can access the flash menu, home buttons, etc and easily navigate back to the information contained in the rest of the flash application.
I have a problem. I have flash application which loads data from XML files. When I start this application in Google Chrome all XML files loads except one, the largest (100kB).
I am having two flash applications on a same web page. Lets say one is already accessing the camera, then if i click on the second application, it will directly start using the camera. I dont want this. I need to check if any other flash application is already accessing the camera in the same web page. Let me tell you that we cant use Camera.getCamera() and check if the camera==null, this wont work, since the camera is available.
I would like to know is it possible to access the flash application object loaded in the default web browser and programatically get a screenshot of the application only.
There is a wide known issue with printing of Flash content in Firefox and Chrome browsers.So,one solution was created by "AnyCharts".But it seems not to work.I also tried to implement the latest version of the component that is now hosted and Google Code.I did exactly as the manual prescribes but it still doesn't work.AnyChart guys say on their blog page that something should be done with CSS as well ,but as you can see from the manual at Flash-Print-Fix home page ,there is no mention about CSS setup. My code works like this:
I'm trying to debug my flash application and when I build and run it in debug(in FlashDevelop), it crashes. Is there a dump file which can give me information about what caused the crash?
i have created a silverlight application , but i need to embed it to a Flash file(swf) which it runs with Flash Player ( whithout using browser), I had found a solutions to call it using javascript, but it still needs my flash file run inside the browser, dose any one can help me, Either to run js inside swf (without need of browser) or any other way that i can embed my Silverlight application inside Flash.
I've written a little video game in Flex that runs in a browser. The player moves by pushing the arrow buttons on the keyboard, so I need to capture those keystrokes. In fact, the game action starts when the player presses one of those keys.In order to capture the keystrokes, the Flash/Flex application, not just the browser, needs to have the focus.How can I ensure that the application has the focus? I've implemented a bit of a hack: A "Begin" button you must click to start the game. The only point of this button is to ensure that the app has the focus.
I have an application on FMS. When a user connect to FMS it will create an application instance. My question is that if all users that connect to it disconnect the instance will be unload automatically?
I figure that this code can be reduced with a for statement, but I can't figure it out. Here is my code, and below that is my attempt.On the stage I have 6 movieclips named nav1_ani, nav2_ani, etc. I also have 6 buttons above them named nav1, nav2, nav3, etc.Here is my code, here I got #5 and #6 working. Instead of duplicating all this code, is there a way to bunch it all into one "for" statement?
Just finished some swf files update, but as computers retain information (cookies) if site as been visited before, im not sure that everybody will see the update. How can i prevent this?
However I find that if I try to test my movie after making some quick changes, I can't bind to the same address:port. I'm guessing that somehow that the port is still occupied. I get a "Operation attempted on invalid socket" error.But if I wait a bit and then test my movie, I can bind to the address:port. The close() is not taking affect. Can I try to close() this when the user decides to exit the app? Is there some sort of event that allows me to do something before the app quits?
A project I'm working on is working just fine at first, but as I perform more actions, it slows down noticeably. I've made sure to clear any onEnterFrame and setInterval events, so I don't think the problem lies there. Most likely, it's because practically every time an action occurs, much of the content on the screen is redrawn/recreated. However, every time I create a movie clip, text field, shapes, etc., I call a function to remove it beforehand:
Code: function killThis(mc:MovieClip, thingsName:String):Void{ var obj:Object = mc[thingsName]; if (obj instanceof MovieClip){[code]..........
I made air application which contain drag and drop functionality. The application works fine when I run it from flash. I'm trying to use this application on web site but unfortunately when I'm trying to run the application I get error:
VerifyError: Error #1014: Class flash.events::NativeDragEvent could not be found.
I am working on integrating an air application with a web application and for the most part it works.The only issue that I am having is that when I attempt to pass variables from my launching badge, the application does not load and I get no errors from my swf.
The things is, I've build an application in flex which suppose to be for web but when I'm running it through the Flash builder, it opens up flash player app instead of opening in a web browser. I've tried to do "run as webapplication" but failed.
We have an AIR client which talks to a WAMP server. We store documents.One of the customer requirement is: they want to their website users to view the documents stored in the AIR application. It should be a read only access. The users will not have our air client installed on their machines. All they do is to check the customer's website.
I am developing small application for training purposes. There after click on the button is done, the new panel is added to application, to the button of the application. Once I come across strange problem. The vertical scroll bar never appears.
