In Move1.swf I am loading Movie2.swf like below:
ActionScript Code:
var myvalue:Number = 0;
var UploadLoad:Loader = new Loader();
UploadLoad.load(new URLRequest("Movie2.swf"));
UploadLoad.contentLoaderInfo.addEventListener(Event.COMPLETE, endNavListener);
function endNavListener(e:Event):void {
var UploadForm=MovieClip(UploadLoad.content);
stage.addChild(UploadForm);
UploadForm.x=0;
UploadForm.y=0;}
But I am having one variable in Movie1.swf which is called myvalue, I want to assign some value for myvalue from Movie2.swf. So I have coded like
ActionScript Code:
MovieClip(parent).myvalue = 100;
But the value is not passing ....

I have a parent swf which loads many child swfs (though only one is displayed at a time). My intention was to use the loaded SWFs document class to retrieve an array of objects to be assigned a tab index, combine this with the parent's own array of objects and apply sequential tab indices to them all. But what happens is actually that the parent's objects are assigned an index, but the external swf is unaffected. In fact, the external swf retains its automatic tab indexing, when I would expect that having set a value for InteractiveObject.tabIndex, automatic tab indexing would be disabled.
I've seen similar tales elsewhere. Most posts I've read are wanting to load an external swf, give it focus and loop through those objects, then close the swf and return to looping through the parent. However I would like loop through all objects as one. including manipulating the focus manager(s), and basically fiddling with every tab-related property I know.

I have made a piece of flash that runs on an xml document and now I need to pass a flash variable (via the html swfobject) to the flash to dictate this xml location. The variable is successfully passed if I embed the main swf straight into the swfobject.The problem is I am using a preloader swf to load the main swf onto the page and I can't seem to work out how to pass the variable (from swfobject) from the preloader to the main swf.

I have two swf, A.swf and B.swf: B.swf is a child of A.swf. Each swf has its DocumentClass. Now: I must pass 4 arrays from A.swf to the DocumentClass of B.swf. Which could be the best way? Is a listener in B.swf a good idea? I noticed there's the possibility to send data over the querystring but I would like to avoid this solution, if possible.

I'm passing a number in my HTML through FlashVars to a swf, I load an external swf into that parent swf which needs the variable that I passed.
I can use the variable passed in the parent, but I just can't understand how to attain that value in the child swf.
I've been looking into dispatch event but it seems way overkill. Haven't seen any examples dealing with something so simple.

What's the strategy for getting a child to access variables in a parent.I have a Main class.In that class I create instances of a Unit class and save those to an array.In the Unit class, I want to access the x and y coordinates of other instances of the Unit class.So I'd like to access that array I made in the Main class.I tried:this.parent.theArray[i].xbut that doesn't work. I tried using the get command, but I don't really know how to, so my efforts failed.

I'm trying to access some variables from my parent in my child MC.
Parent code:
var data_history:String;
function finish_checkUp(event:Event):void{
var checkUp_stat:String;
[Code]....
Now as you can see, i have tried the trace method, but with no luck. Flash doesn't report any errors regarding the trace method, but does report the two undefined vars (data_history). Ive tried to use the trace method above all the functions, at the top of the script, still the same errors though.

Wondering how to do this:
Parent swf has a class loaded, lets call it 'GlobalUtilities'. Parent swf loads in child swf. Child swf wants to use some of the 'GlobalUtilities' class that is in the parent.
How can I accomplish this? The problem I'm having right now is, when I export the child swf, I'll just error out since it can't find the reference (obviously, since it's not loaded into the parent yet).

im working with my main FLA and a script for it child.as i have created a variable in the parent, "svar:Number = 0;" i would like the child to be able to modify this variable when certain triggers are met i've tried something like this in the "child.as" but im assuming its probably much more complicated
[Code]...
im wondering if there is a simple command such as this to call upon an existing variable in the parent? if not, is there a way i can import the variables using the import command?

I'm having some trouble getting to grips with how a child can refer to the variables of parents. Here is my Main.as :
package
{
import flash.display.MovieClip;
public class Main extends MovieClip
[code]....
Using trace(MovieClip(parent).i) instead I get:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

how can I pass a variable from a parent flash file to a child flash file which it calls?We have a parent flash file which imports various child flash files based on instructions in an XML file. It's probably easier to see an example - opg2DOTcoDOTuk/flash/yay.html (replace the DOTs, couldn't post an url due to restrictions) - the text above each page, and the 'enlarge page' lightbox links are all in seperate flash files (one per double page) which are brought in, depending on the pages you are looking at, based on the instructions in an XML file which looks like this...
<page ani_swf="pages/text1.swf">pages/white.jpg</page>
<page ani_swf="pages/text1.swf">pages/0001.jpg</page>
<page ani_swf="pages/text2.swf">pages/0002.jpg</page>
<page ani_swf="pages/text2.swf">pages/0003.jpg</page>
etc, where the swf is the header flash file containing the text and one or two lightbox links, and the jpg files are the page images that appear.We had to repeat the imported child flash file because of a glitch when you go backwards through the book otherwise.
This system has been fine for us up until now but recently we've had to look at making it a dynamic system, so the content of the book can be varied depending on a variable being passed into the parent file via FlashVars...
<param name="FlashVars" value="zone=1" />
<embed src="newbook3.swf" FlashVars="zone=1" ....etc
This makes the book load an xml file called "1"). This is fine, except we also need to vary the 'enlarge page' target images to match.The 'enlarge page' links are currently hard coded into each child flash file, like this...
on (release){
getURL("javascript:SWFDelegate('imagename.jpg','Ex ample');");
}
- What we've tried so far:
1. Trying to pass the variables in querystrings from the XML
eg.
<page ani_swf="pages/text2.swf?var1=image1&var2=image2">pages/0002.jpg</page>
<page ani_swf="pages/text2.swf?var1=image1&var2=image2">pages/0003.jpg</page>
with the child flash setting it's action like this...
on (release){
var image1 = var1 + ".jpg"
getURL("javascript:SWFDelegate(image1,'Example');" );
}
I'm not sure if the syntax here is correct. We have to add the ".jpg" in here because, as far as I understand it, you can't pass "." in a querystring.
2. Passing the variables for the child into the parent
I read somewhere that variables passed to a parent are automatically available to a child. Not sure if this is true, but it didn't work for me when I tried it like...
<param name="FlashVars" value="zone=1?var1=image1&var2=image2" />
<embed src="newbook3.swf" FlashVars="zone=1?var1=image1&var2=image2" ....etc
Combined with...
on (release){
var image1 = var1 + ".jpg"
getURL("javascript:SWFDelegate(image1,'Example');" );
}
...in the child button action.

I have several .as files. The first that loads is Main.as;
package
{
import flash.display.MovieClip;
public class Main extends MovieClip
{
[code]....
So this MC gives the user the ability to type in their name and store it into the parents playerName variable. With the intention that I can refer to it at any point later in any other MC. It stores it okay, a trace proves that, but a problem comes when this movieclip is replaced by the new one ZoneSelector;
package
{
import flash.display.MovieClip;
import flash.events.MouseEvent;
[code]....
As you can see, there's hardly anything in the this .as file. But everytime the trace(MovieClip(parent).playerName) tries to run I get the following error;
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at ZoneSelector()
at Setup/onbeginGameButtonClick()
It's as if the ZoneSelector runs its entire script before the playerName is set..or something like that.

My question is not like the one I read because the context is different: Let's say instead of embedding a flash inside an html page with some flashvars, I want to embed it inside another flash or flex. How to set the flashvars in this case (using ActionScript 3)? So how to embed Flash in another flash and set same variables as it was embedded in html by passing querystring or flashvars.

I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.[code]Sprite2 is a rectangle. When I rotate it, of course, the height of its parent, SpriteP, GROWS. But I would expect that height to go back to what it should be when I'm removing Sprite2!And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200.

i am slightly confused about the parent and child relationship. lets assume we have several different instances, what would be difference of adding them all as children of the stage and creating a parent-child hierarchy between them(other than the access path).

I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.
When Sprite2 is NOT rotated:
Code:
trace(SpriteP.width + ' ' + SpriteP.height); //100 250.
SpriteP.removeChild(Sprite2)
trace(SpriteP.width + ' ' + SpriteP.height); //100 200. -> works, 200 is good.
When Sprite2 is rotated at 90:

And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200. But if I rotate Sprite2, the Parent won't update its bounds.
