Unload movieclip /swf

Hi there.
I have the index.swf and I want to open another swf (called about.swf). I have some buttons in the index, including the "home" button to unload.
I also created a movielip, that has buttons inside it that let the person click to navigate to another swf.
In the index I have the following code:
var aboutURL:URLRequest = new URLRequest("about.swf");
var contentor:Loader = new Loader();
addChild(contentor);
contentor.x = 92;
contentor.y = 95;
about_btn.addEventListener(MouseEvent.CLICK, openAbout);
function openAbout (e:MouseEvent)
contentor.load(aboutURL);
This code lets me click on the about_btn and load the about.swf. I also have a home_btn to unload the "contentor" (which I dont show in this code).
Inside the movieclip I added an actions layer and put the following code:
var aboutURL:URLRequest = new URLRequest("about.swf");
var portfolioURL:URLRequest = new URLRequest("portfolio.swf");
var contentor:Loader = new Loader();
MovieClip(parent).addChild(contentor);
contentor.x = 92;
contentor.y = 95;
aboutmc_btn.addEventListener(MouseEvent.CLICK, openAbout);
function openAbout (e:MouseEvent)
contentor.load(aboutURL);
In this code I created a button called "aboutmc_btn" inside the movieclip that, when clicked, shows the same about.swf. The problem is that when I click on the "home" button (which is on the index and not inside the movieclip) the .swf "contentor" remains there and the movieclip continues there.
What should I do to unload both the movieclip and the about.swf after I click in the aboutmc_button?
Thanks a lot!!!

The curious thing is that if the button is outside of the movieclip and opens a new swf, when i click on the home button to unload the swf it works. but if the swf is opened by clicking on the button that is inside of the movieclip, and then i click on the home button to unload the swf, the swf remains in the stage. i think i have to include something like a remove ... in the home button to kill the URLRequest called by the button inside the movieclip no? I just don't know what to add..

Remove / unload external swf file(s) from the main flash file and load a new swf file and garbage collection from memory.

I can't seem to remove / unload the external swf files e.g when the carousel.swf (portfolio) is displayed and I press the about button the about content is overlapping the carousel (portfolio) . How can I remove / unload an external swf file from the main flash file and load a new swf file, while at the same time removing garbage collection from memory?
This is the error message(s) I am receiving: "TypeError: Error #2007: Parameter child must be non-null.

Andrei1,
Thank you for the helpful advice. I made the changes as you suggested but I am receiving a #1009 error message even though my site is working the way I wan it to work. I would still like to fix the errors so that my site runs and error free. This is the error I am receiving:
"TypeError: Error #1009: Cannot access a property or method of a null object reference."
I'm sure this is not the best method to unload loaders and I am guessing this is why I am receiving the following error message.
     loader.unload();
     loader2.unload();
     loader3.unload();
I also tried creating a function to unload the loader but received the same error message and my portfolio swf was not showing at all.
     function killLoad():void{
     try { loader.close(); loader2.close; loader3.close;} catch (e:*) {}
     loader.unload(); loader2.unload(); loader3.unload();
I have a question regarding suggestion you made to set Mouse Event to "null". What does this do setting the MouseEvent do exactly? Also, since I've set the MouseEvent to null do I also have to set the loader to null? e.g.
---- Here is my updated code ----
// variable for external loaders
var loader:Loader;
var loader1:Loader;
var loader2:Loader;
var loader3:Loader;
// makes borders resize with browser size
function resizeHandler(event:Event):void {
// resizes portfolio page to center
     loader.x = (stage.stageWidth - loader.width) * .5;
     loader.y = (stage.stageHeight - loader.height) * .5;
// resizes about page to center
     loader3.x = (stage.stageWidth - 482) * .5 - 260;
     loader3.y = (stage.stageHeight - 492) * .5 - 140;

Need help unloading an .swf

I'm using flash CS5, AS3
I'm making a huge module that has a central "Hub" (table of contents) which contains all links to the other slides which are individual .swf files.
The issue is, from the main hub, i click on the link to open a swf and it starts to play. if the button that returns you to the Hub is pushed before the whole .swf plays through, the symbols and tweens from the swf that was just unloaded, still show up on top of the Hub and keep playing. anyone know how i can fix this?
code in frame 1 of all swfs:
this.btn_hub.addEventListener(MouseEvent.CLICK, SWFhub);
var fl_Loader:Loader;
//This variable keeps track of whether you want to load or unload the SWF
var fl_ToLoad:Boolean = true;
function SWFhub(event:MouseEvent):void
        fl_Loader.unload();
        removeChild(fl_Loader);
        fl_Loader = null;
        fl_Loader = new Loader();
        fl_Loader.load(new URLRequest("Slide HUB.swf"));
        addChild(fl_Loader);
    SoundMixer.stopAll();
any help would be appreciated!
-= Sondax =-

a few issues... for the code that goes on the loaded swf, the button doesn't return you back to the hub. i changed the first line to "this.btn_hub.addEventListener(MouseEvent.CLICK,unloadF);", but still doesn't work. (btn_hub is name of button that returns you to the hub)
for the hub, when i copy and paste the code to add buttons for the other slides, i get errors of duplicate functions:
Scene 1, Layer 'actions', Frame 1, Line 29
1151: A conflict exists with definition fl_Loader in namespace internal.
Scene 1, Layer 'actions', Frame 1, Line 41
1021: Duplicate function definition.

1021: Duplicate function definition.
line 29 = var fl_Loader:Loader=new Loader();
line 41 = function completeF(e:Event):void{
line 45 = function unloadF(e:Event):void{
the full code in the hub (just 2 buttons added so far):
stop();
this.btn_62.addEventListener(MouseEvent.CLICK, SWF62);
var fl_Loader:Loader=new Loader();
fl_Loader.contentLoaderInfo.addEventListener(Event.COMPLETE,completeF) ;

AS3 Unloading external SWF piling up problem

I have two buttons on main SWF what loads and Unload two external SWFs back and forth.
Also one timer function is calling external Screen saver SWF and unload the existing one when no interaction found.
I am using unloadAndStop() function to unload the external SWFs.
But after loading and unloading external SWFs, I am facing piling up or stack overflow problem.
Any help will be highly appreciated.

Transition_Manager and unloading external swf problems

Hi there
I´m having a few problems with my project which i although it work it has some unpleasant bugs that i´m trying to solve for days.
When i load external swf´s they show up on top of the Menu button.Maybe because the button i´m pressing is inside the same movieclip as the Menu.
Explaining better here´s a little diagram of my site:

Like i said the swf´s show up on top of the Menu and i need it to dissapear.
Also i want to unload the swf currently in scene so that when i load another one they don´t pile on top of each other.
Pls help. Thanks

Oh btw, i´m having an error 1069 Property TransitionManager not found in subMenu and there is no default value
at fl.transitions::TransitionManager$/start()
    at Painel3/onClick()
This doesn´t happen when i uncheck the Export for actionscript in the subMenu class but i can´t do that or else the buttons wont work.

Unable to unload external swf which is using runtime sharing

Unable to unload external swf which is using runtime sharing of some symbols and classes.
Due to this problem i am unable to load another swf or the same for the second time and getting errors at runtime.
It works fine when the swf is opened in IE.
Can anyone please help me in solving the issue.

thank you
i have tried to use   this.parent.Click_To_Close but it gives compilation error
i checked the tutorial about custom events i think its little complex for me now to understand the typeriter app.
also i cheked the similer thread and tried to test that code myself..i found that the last block of main movie does not works and does not unload the loader2. however all the trace are showing in the output windows that i added to check the code but last trace from the main movie is not showig...
trace("child removed from Main Movie")
so if this can work somehow i will use this method of event dispatch in my application that i am working...
Thank you
-----main movie ---------
var loader1:Loader = new Loader();
var loader2:Loader = new Loader();
loader1.contentLoaderInfo.addEventListener(Event.COMPLETE, assignMovie1Listener);
loader1.load(new URLRequest("movie_1.swf"));
loader2.load(new URLRequest("movie_2.swf"));
addChild(loader1);
addChild(loader2);
function assignMovie1Listener(evt:Event):void {
      MovieClip(evt.currentTarget.content).addEventListener("eventTriggered", removeLoader2);
            trace("listner is listning..")
function removeLoader2(evt:Event):void {
      loader2.unloadAndStop();
      removeChild(loader2);
         loader2 = null;
            trace("child removed from Main Movie")
//------------- movie_1.swf code:
removeMovie2_btn.addEventListener(MouseEvent.CLICK , removeMovie2);
function removeMovie2(event:MouseEvent):void
      dispatchEvent(new Event("eventTriggered"));
            trace("event triggered form Child Movie-1");
as u can see when i click close button its triggering the trace from movie-1 but its not unloadign the movie2

Unload external swf from flv component

Please help.
Is it possible to add action script to the flv player
componet buttons?
I am trying to unload an external swf file (voice over) if
the viewer chooses to play one of the many videos in the
presentation. Currently I am using an invisible button over the flv
component play button which unloads the swf. This works but would
rather assign the action directly to the flv play button on press.
Any suggestions? Thank you

Unloading external swf problem - deadline approaching

Hi,
We bought a component, and the developers are not real
helpful so I thought I would try here. We have the well-known AS 3
problem of events continuing to run even after you've unloaded a
swf. Here is what we got:
a main swf loads one of 7 secondary swfs, based on a button
click. each of the secondary swfs contains the component (a 3D
wall) that we purchased. we don't seem to have access to the code.
we unload one swf load the next, and then after we do this a few
times we get the following crash (output way below).
The component does have a closeWall() function, which i'm
assuming cleans things up. The problem is I don't know how to call
a function on an externally loaded swf? Is that possible? In other
words I want to say:
var loader:Loader;
function loadSwf(){
loader = new Loader();
var urlRequest:URLRequest = new URLRequest ("vidSub.swf");
loader.load(urlRequest);
addChildAt(loader, getChildIndex(holder));
function unloadSwf(){
// hey swf, close properly, before I unload you
loader.closeWall();//or something like this
loader.unload();
Thanks so much if you can help.
Doug

I feel for you...
You may want to try to instantiate the thing not through
adding loader to display list but accessing application domain and
creating an instance of its class. Some application will not do a
thing if you just add them to display list and accessing their
interfaces (I love doing that for one :-). In any case - I am not
sure it is such a good idea to add the loader directly - not within
INIT event listener.
You may want to try accessing their application domain and
loop through its properties to see which ones are enumerable. In
the error stack you can see some their classes so you know already
what to access. For instance there is
org.papervision3d.core.utils.InteractiveSceneManager class.
I don't say anything new but it looks like there is the same
event flying around which is dispatched by some listener causing
recursion. Can it be that your custom events have the same type as
theirs? Try to listen to their events through making listener
listen in capture phase by setting third parameter to true:
blah.addEventListener("eventType", eventHandler, true) - you may be
able to explicitly remove their event listener if you know which
one. Or, perhaps, this is your mouse event that conflicts with
theirs...
Sorry I cannot be more helpful.

How to unload/load swf

I have a Flash movie that automatically opens another Flash movie inside it. The main swf has a "Start" button at the bottom. When I click the Start button I want to unload the swf that loaded automatically (as a placeholder) and load a new Flash video swf. I'm doing this to create a placeholder for the video. I don't know what code I need to use on the button to unload the automatic swf and load the new swf video.

if you don't need to stop any loaded streams (like sound/video), you can just reuse the same loader to load the next swf. otherwise, apply unloadAndStop() to your loader before loading the next swf.

Unload an SWF?

I'm trying to unload an SWF that has been loaded by the following code, but can't get it to work.
This code loads the SWF and works fine:
btn1.onRelease=function(){
myContainer.loadMovie("LibraryBooks.swf");
gotoAndStop("35b");
This is the code I'm trying, which doesn't work (the gotoAndStop works but the unload SWF doesn't work)
resetbtn.onRelease=function(){
myContainer.unloadMovie("LibraryBooks.swf");
gotoAndStop("35");
thx-

unloadMovie() takes no parameters:
btn1.onRelease=function(){
myContainer.loadMovie("LibraryBooks.swf");
gotoAndStop("35b");
resetbtn.onRelease=function(){
myContainer.unloadMovie();
gotoAndStop("35");

Loading/Unloading a .swf that adds event listeners to the Stage

Hi all,
Disclaimer
Apologies if I suck so bad at using forum search that the answer to this is on page 1 somewhere; I tried...
Question
I am loading and unloading a .swf to which I do not have source code access. This .swf places several event listeners on the stage, as far as I can tell. When the .swf is unloaded, the event listeners placed upon the stage still seem to be in effect. Using unloadAndStop doesn't seem to do it, and I have to target Flash Player 9, anyway, so can't really use it. Is there any other way I can keep this external .swf from holding onto my main movie's stage?
Additional info
All eventListeners and references being set by my code are removed.
I've managed a little contact with the author of the .swf:
I've requested he provide a dispose() method I can call to get all the listeners removed, and send an updated .swf.
He's suggested that I should be able to avoid the problem by loading into a unique ApplicationDomain. I'm not terribly familiar with this, but have given it a try without much success. Is this a valid solution - can I really protect my 'stage' by properly using ApplicationDomains - or do I need to persist in trying to get a public dispose() method built in?
Thanks in advance!
Cheers, John

thanks for reply sir

UNLOAD External SWF on Mouseclick

All of my buttons load their respective external swf files. However, they load on top of each other. How do I set each button to UNLOAD the external swf's that have already been loaded by the previous buttons.
Here is what I have now:
movieClip_1.addEventListener(MouseEvent.CLICK, fl_ClickToLoadUnloadSWF);
var fl_Loader:Loader;
//This variable keeps track of whether you want to load or unload the SWF
var fl_ToLoad:Boolean = true;
fl_ClickToLoadUnloadSWF(null); // load the swf at the start
function fl_ClickToLoadUnloadSWF(event:MouseEvent):void
    if(fl_ToLoad)
        fl_Loader = new Loader();
        fl_Loader.load(new URLRequest("album1.swf"));
        addChild(fl_Loader);
        fl_ToLoad = false;
    else
        fl_Loader.unload();
        removeChild(fl_Loader);
        fl_Loader = null;
        fl_ToLoad = true;
movieClip_2.addEventListener(MouseEvent.CLICK, fl_ClickToLoadUnloadSWF_2);
var fl_Loader_2:Loader;
//This variable keeps track of whether you want to load or unload the SWF
var fl_ToLoad_2:Boolean = true;
function fl_ClickToLoadUnloadSWF_2(event:MouseEvent):void
    if(fl_ToLoad_2)
        fl_Loader_2 = new Loader();
        fl_Loader_2.load(new URLRequest("album2.swf"));
        addChild(fl_Loader_2);
    else
        fl_Loader_2.unload();
        removeChild(fl_Loader_2);
        fl_Loader_2 = null;
    // Toggle whether you want to load or unload the SWF
    fl_ToLoad_2 = !fl_ToLoad_2;
movieClip_3.addEventListener(MouseEvent.CLICK, fl_ClickToLoadUnloadSWF_3);
var fl_Loader_3:Loader;
//This variable keeps track of whether you want to load or unload the SWF
var fl_ToLoad_3:Boolean = true;
function fl_ClickToLoadUnloadSWF_3(event:MouseEvent):void
    if(fl_ToLoad_3)
        fl_Loader_3 = new Loader();
        fl_Loader_3.load(new URLRequest("album3.swf"));
        addChild(fl_Loader_3);
    else
        fl_Loader_3.unload();
        removeChild(fl_Loader_3);
        fl_Loader_3 = null;
    // Toggle whether you want to load or unload the SWF
    fl_ToLoad_3 = !fl_ToLoad_3;

Your code is too much bad , sorry to say.
Please try the following code that I have made for you.
Here the code is much too smaller than yours and also hope it will solve your problem.
import flash.events.MouseEvent;
import flash.display.Loader;
movieClip_1.addEventListener(MouseEvent.CLICK, loadUnloadSWF);
movieClip_2.addEventListener(MouseEvent.CLICK, loadUnloadSWF);
movieClip_3.addEventListener(MouseEvent.CLICK, loadUnloadSWF);
var fl_ToLoad:Boolean = true;
var fl_Loader:Loader;
var previous_btn:String;
loadUnloadSWF(null);
function loadUnloadSWF(event:MouseEvent):void
    try{
    var str:String = event.target.name.split("_")[1];
    }catch(e:Error){str="1";}
    try{
    fl_Loader.unload();
    }catch(e:Error){}
    if(previous_btn != str)
        fl_Loader = new Loader();
        fl_Loader.load(new URLRequest("album"+str+".swf"));
        addChild(fl_Loader);
    previous_btn = str;

[svn:fx-3.x] 12301: Clean up lastSystemManager reference when SWFLoader unloads a SWF.

Revision: 12301
Revision: 12301
Author:   [email protected]
Date:     2009-11-30 14:52:14 -0800 (Mon, 30 Nov 2009)
Log Message:
Clean up lastSystemManager reference when SWFLoader unloads a SWF.
When SWFLoader unloads itself null out SystemManager.lastSystemManager reference if the reference is the content it loaded. This will prevent SWFLoader leak reports when simply loading and unloading a swf.
Move the removeInitSystemManagerCompleteListener() code before we unload because the contentLoaderInfo is destroyed by the time we get the unload message.
Add code to prevent double loading.

Trouble unloading external swf's

Hey, so firstly, I am completely new to Flash and know absolutely nothing :| But heres my problem:
In one particular keyframe, I have five buttons on the left hand side of my stage, that when clicked, display an external swf on the right handside. It works perfect fine using the code below. However on this frame where all this is going on, I also have a back button that i want to link back to the home page. But I just CAN'T seem to get it to unload the external swfs as well as go back in the timeline Any assistance would be great! Cheers

Oops sorry I forgot to put "function"!
function onBackButtonClick(e:MouseEvent):void {
Obviously your back button needs an event listener to call this function.

Simple way to unload/reload swf in iOS.

I'm trying to find a way to completely reload/restart my app at the end or use a seperate collection of swf files when creating an AIR iOS app in Flash Professional. I used a UIloader in flash with a simple preloader before the simple app that I've made but I get the warning "ActionScript contained in externally loaded SWF files will be ignored on iOS devices."
My app works perfectly the first time through, but seems to encounter problems when played a second time, even if all the eventlisteners are removed. I'd like to completely refresh the app when it's played through a second time, either by unloading the main swf and switching to a preloader like I have previosly tried, or by seperating each scene into an easily loadable swf.
Is there an AIR compatible alternative to the UIloader component, or something similar that would allow me to use external swf files with actionscript?
Thanks for any help.

SWCs would be added in the ActionScript settings of your main FLA. Suppose you had one that was called Game1.swc, and its document class is called Game1Main.as, in your main FLA you would have code like this:
var currentgame:MovieClip;
currentgame = new Game1Main() as MovieClip;
You can then add listeners to it just like you would have by getting the content of a loader.
One tricky thing though, the document class of your main FLA will need to know about the class names of the SWCs. That can easily be handled by just mentioning the class names in your main FLA class. For example, to know about three games you might load later, you could have this line:
var gameclasses:Array = ;
That’s enough to let the compiler know about those classes.
