Typically you create a Vector (strongly typed array) specifying a data type like:
new Vector<PictureBox>();
However I need to create a utility method that should be able to create a vector of any given datatype. Is it possible to specify a type using a variable instead of hard-coding it?
var type:Class = PictureBox;
new Vector<type>();

I need to create a custom Object that basically stores some custom parameters (properties?), which I have successfully done, and the code below works fine.
PHP Code:
myObject = new Object();
myObject.nameLabel = "New Releases";
myObject.artOrientation = "portrait";
myObject.artAmount = 5;
I find the new compiler and debugger capabilities very useful, since I'm not the most detail-oriented, so I (usually) like that Flash forces me to strict-type my variables and such. Anyway, I was wondering if it's a "best practice" to strict data type a custom objects' properties, and if so, how to do it in the logic above? I kept getting syntax errors when I just tried it initially.
I know if I created a custom Class .AS file, I would be forced to data type the properties... but I'd rather just do it "in-line" in my main .FLA file. Also, I know I can just pass typed VARIABLES to the properties... but I'd rather have the properties strict-typed themselves... so if I try to pass a variable as the wrong type, then I would still get an error.

I have a quick question for you all. I'm trying to convert over some ActionScript code to C++ and am having a difficult time with this one line:
private var edges:Vector.<Array> What is this exactly? Is this essentially a multidimensional vector then? Or is this simply declaring the vector as a container? I understand from researching that vectors, like C++ vectors, have to be declared with a type. However, in C++ I can't just put down Array, I have to use another vector (probably) so it looks like:
I don't expect you guys to know the C++ equivalent because I'm primarily posting this with AS tags, but if you could confirm my understand of the AS half, that would be great. I did some googling but didn't find any cases where someone used Array as it's type.

I have a class which takes a Vector.<DisplayObject> in it's constructor. I had expected it to be ok to create instances of this class by passing Vectors of types that are subclasses to the DisplayObject class (in this case Sprite ans SimpleButton). But it doesn't work. And casting these Vectors as Vector.<DisplayObject> when declaring the instances doesn't work either. [code]...

Trying to create a 2D vector. I'm getting type coercion errors when trying to store the 2nd vector inside the first.
Code:
var vector1:Vector.<Vector> = new Vector.<Vector>
var vector2:Vector.<CustomClass> = new Vector.<CustomClass>
for(var i:int=0;i<5;i++){
vector2[i] = new CustomClass()
}
vector1[0] = vector2;
1067: Implicit coercion of a value of type __AS3__.vec:Vector.<CustomClass> to an unrelated type __AS3__.vec:Vector.

I have a class member in an ActionScript 3 class that looks something like this:
private var m_myvect :Vector.<MyType> = new <MyType>[];
I'm exposing it through a getter, like this:
public function get mydata() :Vector.<MyType>
Which doesn't help when I use it like this:
for (var o:Object in inst.mydata)
{
...
}
... because the type of o is not MyType, but Number instead, because it enumerates the vector indices instead of the data.How would I expose only the data within the vector in a way which:Does not expose the data in a way which allows it to be modified?

I need to know the best method to find an item inside a list (Vector, Array, Dictionary, whatever is faster) of complex type (extensions of Objects and Sprites).I've used "Needle in Haystack" method, but it seems that it isn't fast enough.
E.g.Suppose that I have a collection of Sprites (a pool, in fact).Each sprite will be added to the stage and perform some action. After that, it will die.I don't want to pay the cost to dispose it (garbage collect) and create another (new) one every time so I'll keep the dead sprites in a collection.
Sometimes times I'll call a method that will add a sprite to the stage.This sprite can be a old one, if it is already dead, or a new one, if the pool don't have any free sprite.
One of the scenarios that pushed me to this question was a Particle System.A "head" particle leaving a "trail" of particles every frame and exploding into a flashy multitude of particles... Every frame...Some times this counts up to 50.000 PNGs with motion, rotation, alpha, event dispatching, scale, etc...But, this is JUST ONE scenario...At the moment I'm trying to use a Object Pool with a Linked List...Hopes that it will be faster that running a whole Array/Vector or create new instances every frame an let them dye with Garbage Collection.

What is serialization support like for the new Vector class? I have a Vector.<GameMove> which I'd like to serialize into a ByteArray. GameMove is a custom class. I presume it's necesssary to call registerClassAlias() on GameMove, but do I also have to register Vector.<GameMove>? It's it it's own distinctive type, or is it kinda composed of those two types?

i load in AS3 data into flash and mantain their data type? Like receiving an array and even with arrays in it and recognizing that is an array instead of a standard string.
And if this is possible is it more reliable then using XML?

Flex gives the ability to export a display object as a bitmap as follows:
var bitmapDataBuffer:BitmapData = new BitmapData ( displayObject.width, displayObject.height, false);
bitmapDataBuffer.draw ( displayObject, displayObject.transform.matrix);
Is there a method to export a display object as a vector graphic instead of bitmap data?

Specific to Flash Professional CS5. With its export options greatly reduced, there seems to be no way to make Flash graphics accessible by other programs. Is there any workaround?Currently, Flash can output two kinds of vector images: SWF and FXG, neither of which seem to be importable by most applications, including Fireworks and Illustrator (which write to FXG but not read from it), and Catalyst doesn't seem to write to anything other than what Builder uses. In other words, I know no way to export Flash files to vector formats (besides using Flash CS4).

I have displayobject with vector and image data And I am trying to scale it in order to get big jpeg out of it with JPGEncoder.The thing is that once I am resample it using the Bitmap class (Matrix) and with draw method it's getting pixelated.How can I take a container with vector graphic and bitmap image and rescale it to bitmapdata without getting things pixled.This is the displayobject:The image in the center is high resolution image which I resize and all the other elements are vector graphic.Since the image is high resolution and all the other elements are vectors if I just call the scaleX property of the displayobkect it increase the contenier size and it all looks very good. But if I want to take a bitmap data out of it it's look terrible, The fonts getting pixelated and even the photo.I will like to know it there is a way to do it without getting things pixelated.

I'm looking for a way to take SVG path info (basically a string of coordinates) and dynamically draw it with Actionscript. Icing on the cake would be if those shapes could detect mouse events to trigger JS and dynamically change their appearance (fill, stroke, etc...).
I'm currently trying something similar to this ([URL]) using SVG but it's just too slow in IE. I've also tried Google's SVG Web ([URL]) which basically does exactly what I'm looking for (it converts SVG to Flash in IE) but again, it's sloooooow - which is why I'm considering doing the whole shebang in Flash.

i want to essentially classify a simple function in it's own .as file. the function compares integers. but i don't know how to call the class and receive a boolean return.
here's my class

so now i'd like to write something like this:
if (CompareInts(1, 5) == true). or output 'true' by writing trace(CompareInts(1, 5));

So I have an input TextField and I'm wanting to use a custom font for it. I tried to use setTextFormat() with a TextFormat object, which does not make any difference. When setting embedFonts to true, Nothing at all gets displayed. I know the problem isn't with the TextFormat object, because I can apply the same format to a regular TextField and it works

I'm trying to make my own picture browser for my webpage, and have run into a problem I can't solve. My guess is that this is kinda a newbie-problem, but anyway here I go...
I have made a class (as an extention to MovieClip) in a seperate file where I can load a picture and later resize it into a thumbnail. I have no problem showing them, but when I tried to make a MouseEvent for clicking onto the shown thumbnail and then tries to access the instance the event sends me, I get :
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Loader@22c30791 to ThumbNail.
at PicBrowser_fla::MainTimeline/clickedOnThumbNail()
I don't understand why it complains on 'Loader'!?And what is the best way to access the instance of the 'ThumbNail' in the MouseEvent?
The .as file looks something like this :
Code:
package
{
import flash.display.*;
import flash.events.*;

I have a Flex tree control that holds a tree full of various types of objects. I'd like to change the label of the item based on this type (and other properties). I'd prefer to do this in a custom TreeItemRenderer rather than via label or labelfunction.It seems that whatever I do, I cannot typecheck nor cast the objects and thus I get [Object object] in the nodes of my tree. Here is my renderer:

Running into a problem dispatching a custom event from a parent SWF made in Flex Builder to a child SWF made in Flash CS4 that is loaded at runtime. Namely, whenever the child SWF is dispatched an event, I get a runtime error:
[Code]....
The custom event is defined in a standalone library that both the flex project and the flash project link to staticly. I wanted to go this route so that as I add new types of events, I can rebuild the application and flash swfs and not have to worry about moving .as files around (lets hold off on RSL's until I get this *simple* case worked out).
This error message makes it sound like the application defines a myCustomEvent at compile time, and the flash movie defines its own myCustomEvent when it is published. Then when the application is run, the myCustomEvent dispatched in the application doesn't match the one in the flash swf. Now I thought that application domains were supposed to sort all of this out, where the child uses the parent's definition for any classes that are duplicated. But when I load the child swf and use the current domain in the LoaderContext I still get the same error.
[Code]....
