Flushing loaded swfs from stage target mc?

Hi, I'm using buttons to send the playhead to frames in which swfs are then loaded into an otherwise blank movieclip called "stage_target_mc" ...how can I then flush out the previously loaded swf so only a newly loaded swf displays in "stage_target_mc"? For example, after clicking upon the 'about' button the 'about' swf loads...then if the 'concepts' button is clicked the 'concepts' swf loads -- but the previously loaded 'about' swf still plays...I would like to be able to flush the 'about' swf so only 'concepts' is display, in this example. Thanks!
code associated with buttons used to send playhead to frames "concepts" or "about":
about_btn.addEventListener(MouseEvent.CLICK, displayAbout);
function displayAbout(e:MouseEvent):void {
root.gotoAndStop("about");
concepts_btn.addEventListener(MouseEvent.CLICK, displayConcepts);
function displayConcepts(e:MouseEvent):void {
root.gotoAndStop("concepts");
code on frame called "concepts":
stage_target_loader.load(new URLRequest("swfs/stages/concepts.swf"));
MovieClip(root).stage_target_mc.addChild(stage_target_loader);
code on frame called "about":
stage_target_loader.load(new URLRequest("swfs/stages/about.swf"));
MovieClip(root).stage_target_mc.addChild(stage_target_loader);

Before loading, try using the unloadAndStop() method of the Loader class if you are using a newr version of Flash

How to effectively remove a loaded SWF from the stage?

I can not figure out a proper coding to remove a loded SWF from the stage.
Here is my set up.
I have a layout segmented into labeled section. In the section labeled "products" I have a layout consisting of product images acting as buttons which bring a user to another labeled section "prdctsPopUps"
In the "prdctsPopUps" section I have placed an instance of LoaderMax placed into an mc container. Placing LoaderMax into an mc container automatically resolved an issue of clearing loaded SWFs from stage when I come back to "products" section.
I specified the variable in the "products" section with the following set up:
var sourceVar_ProductsPopUps:String;
function onClickSumix1PopUp(event:MouseEvent):void {
                    sourceVar_ProductsPopUps="prdcts_popups/sumix1-popup_tl.swf";
                    gotoAndPlay("prdctsPopUps");
So each button has its own "....swf" URL and they all open fine and I can come back to "products" section without any issues.
However inside the swf (which loads through LoaderMax which is placed into an mc) there are other buttons which bring a user to labeled section "xyz". Which also functions properly. It opens as it is supposed to be and without any previously loaded "...swf" on the stage.
At the labeled section "xyz" there is a limited set of buttons repeating from section "products" which has to bring a user back to the same set up in the "prdctsPopUps" labeled section and open a corresponding "...swf" .
However only the last opened "...swf" will appear in that section. Effectively the one which was originally opened from the "prdctsPopUps" section and not the one which was supposed to be opened from the "xyz" section.
I can not understand why it would work from one labeled section and not from another. I can not figure out on which section which code/function needed to be placed.
Here is the set up from a button from the "xyz" section whcih supposed to bring a user to the same "prdctsPopUps" section but to load a different "...swf"
var sourceVar_ProductsPopUps_fromXYZ:String;
function onClick_floralytePopUp_fromXYZ(event:MouseEvent) :void {
                    sourceVar_ProductsPopUps_fromXYZ="prdcts_popups/floralyte-popup_tl.swf";
                    gotoAndPlay("prdctsPopUps");
Here is the code set up for the LoaderMax from the "prdctsPopUps" section:
var loaderProductPopUps:SWFLoader = new SWFLoader(sourceVar_ProductsPopUps,
                                                                                                    estimatedBytes:5000,

                                                                                                    onComplete:completeHandler,

function progressHandler(event:LoaderEvent):void{
          progressBarPopUp_mc.gradientbarPopUp_mc.scaleX = loaderProductPopUps.progress;
function completeHandler(event:LoaderEvent):void{
          var loadedImage:ContentDisplay = event.target.content;
          TweenMax.to(progressBarPopUp_mc, 1.5, {alpha:0, scaleX:0.25, scaleY:0.25});
loaderProductPopUps.load();
Is there something which needs to be imported, or specific function needs to be specified in a specific labeled section?

actually, i think you'll need to use something like:
var loaderProductPopUps:SWFLoader;
if ((loaderProductPopUps){
if(loaderProductPopUps.content)){
   loaderProductPopUps.unload();
loaderProductPopUps= new SWFLoader(sourceVar_ProductsPopUps, //the value of sourceVar_ProductsPopUps allows to load mulitple SWFs from the products page.
                                                                                                     estimatedBytes:5000 ,
                                                                                                     container:holderMov ieClip,// more convinient and easier to manage if to place the LoaderMax into an empty mc (holderMovieClip)
                                                                                                                                                                     // if not will work as well. Then the line container:holderMovieClip, has to be replaced with container:this,

Unload and Stop swf from stage

Hi,
I'm a newbie to Flash and Actionscript. I need to give links to around 20 swf files via buttons from the menu.swf. I'm able to give links. But when I come back by clicking HOME button kept at the newly loaded swf the audio files are still being played at the background.
Yes, It has got audio files playing at the back for each slide in the new swfs. When Click on the same link again in menu.swf again the files are being played with the unfinished old file. It's really hectic.
I need to unload it completely from stage when I come back to menu.swf by clicking on HOME button from any of 20 categories.
I used unloadAndStop but it is not doing. I hope that I'm commiting mistakes at somewhere but couldn't predict.
Need some help !
FOR HOME BUTTON:
var _content:Loader = new Loader();
function loadContent(content:String):void {
    if (_content != null) {
        _content.unloadAndStop(true);
        removeChild(_content);
        _content = null;
    var loader:Loader = new Loader();
    loader.load(new URLRequest(content)); //---->>>> I don't really know what should be put in this :-(
    _content = addChild(loader) as Loader;
Home_Button.addEventListener(MouseEvent.CLICK, home);
function home(event:MouseEvent) {
    _content.unloadAndStop(true);
    var homeSWF:URLRequest = new URLRequest("demo.swf");
    _content.load(homeSWF);
    addChild(_content);
FOR MENU.swf button
var loader:Loader = new Loader();
Category1_Button.addEventListener(MouseEvent.CLICK, category1);
function category1(event:MouseEvent):void {
    var Category1SWF:URLRequest = new URLRequest("Category1.swf");
    loader.load(Category1SWF);
    addChild(loader);

Hi,
Can this thread help us?
http://forums.adobe.com/message/3739886
I have seen you have replied to this. Would this give some idea ? Does this script serve the purpose ? I tried replacing the code with appropriate changes and looking like this.
Home Button:
var swf_loader:Loader = new Loader();
///unload previous swf
swf_loader.unloadAndStop();
removeChild(swf_loader);
////load new swf
swf_loader.load(new URLRequest("menu.swf"));
Home_Button.addEventListener(MouseEvent.CLICK, finishLoading);
function finishLoading(e:Event):void{
if(swf_loader.content){
addChildAt(swf_loader, 0);
but getting error as
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
    at flash.display::DisplayObjectContainer/removeChild()
    at Category1_fla::MainTimeline/frame55()
I think I'm complicating the simple thing.
Thanks.

Load SWF on stage with button

Hallo everybody,
I am a new Flash user so please forgive me if my question is
a bit "simple". I want to obtain a flash button that can load SWF
file on stage in a precise position without taking tha button
place. As example please click www.suit-e.de . I have read about
loadMovie e loadMovieNum but I do not not if I am in the right
place. Thank you

To do that you need to design the whole website using the
keyframes and some tweening technics, you dont really need much
complicated actionscript/loadmovie etc. Get to know alittle more
about tweening and using the keyframes plus imagination.
Good luck.

I have crossdomain.xml file in both the servers which is also allowing both the domains. I was not able to figure out the issue. Can anybody help on this.

Controlling loaded swf from main timeline

Hello,
I'm working on loading external swf files for ios. I am able to load the swf files and set them to visible or invisible in different frames. I am having trouble controlling the loaded swf files from the main timeline. Specifically, I would like to have a button on the main timeline, that when clicked will move a loaded swf to frame 1.
Here is a code that loads one swf file:
var myLoader1:Loader;
var loaderContext1:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain, null);
if(myLoader1 == null)
myLoader1 = new Loader();
addChild(myLoader1);
myLoader1.load(new URLRequest("folder/file1.swf"),loaderContext1);
myLoader1.visible = true;
backbutton.addEventListener(MouseEvent.MOUSE_DOWN, backbutton1);
function backbutton1(myEvent:MouseEvent):void {???????????? myLoader1.gotoAndStop(1);} (this line does not work)
(Once I load file1.swf, within the file1.swf I click a forward button to move to different frames. My question is: how do I code the 'backbutton' on the main timeline so that it causes the loaded file1.swf to go to frame 1?)
Thank you for your help.

sure.
if the movieclip on the loaded swf's main timeline has reference mc, you would use:
MovieClip(myLoader.content).mc.gotoAndStop(1);
p.s. you might find the following helpful, http://kb2.adobe.com/community/publishing/918/cpsid_91887.html

Using jump menu to load swf to a target...

is it possible to use the selections of a jump menu, once when one is selected to load a .swf to a certain target on the page.
i.e. at www.meadowlarkco.com/index2_new8.htm I have a jump menu with selections within it. Is it possible for instance once I select "flatbed services" for it to a load a new .swf movie to a location on the page, much like an empty mc holder would be used. Then when each new selection is made from the jump menu it will load the according .swf to the same location.....how would I start this script to change my current jump menu?
thanks for any help provided

For many reasons, a JumpMenu would not be my first choice for this. You need a stable cross browser media player embedded into the page and a playlist of files to pull this off.
Have a look at Wimpy Rave with Full Advertising / Playlists (NOTICE: this link contains auto playing sound and video).

Load SWF from text link?

Hi
I have navigation movieclips which load external SWF's into
my "loader_mc" empty movie clip on my stage, however I need to add
some text onto certain pages and from this text create hyperlinks
which are meant to load external SWF's also into the same loader_mc
movie clip.
Firstly, is this even possible - i.e. load external swf's
from text links?
Secondly, if so, how? When i select the text, the actions
panel is always disabled.
Any suggestions or advice would be greatly appreciated.
Thanks

I just have stop(); on the swf
this is the code for adding the swf
addBubbles(e.currentTarget);
        private function addBubbles(e:Object):void
            var xx:Number = e.x;
            var yy:Number = e.y;
            var bubble:boxg = new boxg();
            bubble.x = xx;
            bubble.y = yy;
            e.parent.addChild(bubble);
            bubble.gotoAndPlay(1);
But when i run the debug i get an error on this line - e.parent.addChild(bubble);
Error #1009: Cannot access a property or method of a null object reference.
    at InventoryItem/addBubbles()[C:\Documents and Settings\frida\Desktop\hello99\hello3\InventoryItem.as:39]
    at InventoryItem/mouseClickHandler()[C:\Documents and Settings\frida\Desktop\hello99\hello3\InventoryItem.as:28]
what that means?
Thank you

Multiple MovieClips Loading SWF From Same Array (Posted Code)

Hey there,
I'm currently working on a project that has eight separate movieclips (for loading content) on separate layers. I have placed code in these mc's to randomly draw from the same array of 61 different swf's. Each mc randomizes the array just fine, but here's the problem. The code works great for one instance, but as soon as I add the code (including renaming) to the other mc's, the swf won't load/play. I am not getting an compiler errors, and am kinda stuck as to what the problem may be. Here's an example of the code I'm using. It is the same for each mc, except I'm renaming the variables as well as the instances for each mc. Thanks for any suggestions.

Thanks for taking a look at this. The randomizer seems to work just fine, as here is a sample output from the trace:

Might you be able to lead me down a better path? I'm currently unable to get this to function for multiple symbols. The previous is the code that I've placed on the first keyframe of a movieclip with an instance name of movieTarget. Works swimmingly for one, but once the code is placed on the other symbols on different layers, it seems to only work on the lowest layer in the project.

Load swf from memory into FlahPlayer ActiveX

Hello,
I am developing an application which must load a swf file
into the
activex directly from memory. My development is almost
complete but I
have a problem with the last part of the implementation.
I am using an implementation of IBindHost, and passing the
stream
trough an IMoniker implementation.
I don't know if someone here can help me, if so I will
explain deeply
my question.
Thanks,
Vicente.

Loading SWF from CS5

Hi,
I'm porting a plug-in from CS4 to CS5 which has Flex components to it. There is no mention of any changes in the Flex portion of the API in the porting guide, but yet it's obviously changed. To make things worse, the sample flexuistroke is missing all the C++ code.
I made the obvious change from LoadMovie to LoadSWF and while all function calls succeed, the SWF file never shows up in our panel.
Can anyone tell me either what's changed or provide an example?
Thanks

later some debug, I found this:
buttons on a container MovieClip react slower than buttons on main timeline (all air versions [desktop, android])
seems (and sounds, to say the truth) to be correct the running path: [mouse events:]
OVER -> DOWN [and then] UP -> CLICK
but,
OVER -> DOWN [and then] UP -> CLICK with buttons in main timeline is fast enough
OVER -> DOWN [and then] UP -> CLICK with buttons a MovieCLip is not fast enough to be acceptable
and, in the case:
OVER -> DOWN [and then] UP -> CLICK with buttons a MovieCLip is AIR for Android is terribly SLOW (can't use buttons?!?!)
adobe, have I to open a bug report?
Massimiliano
nb AIR 2.5.1 (I ask to myself if previous versions of AIR were free from this bug, or if worldwide developers are used to not to use buttons in movieclips when developing for AIR...)

Loading swf from database
