use Arrays :)

You can't use code like
 
    this["movie_ number_" + idNumber];
 
unless you've pre-declared vars (or getter/setters) named
movie_number0, movieNumber1, movieNumber2, etc. -- which doesn't make any sense
because you usually don't know how many you'll need -- or made your class
dynamic -- which isn't recommended because dynamic vars are slower. Otherwise,
you'll get a runtime error that, for example, movie_number3 isn't a valid
property on your class. (I don't remember the exact wording of the error
message.)
 
So forget about that. You need to understand how to use an
Array to keep track of multiple instances. It's easy:
 
1. Declare an instance var of type Array and initialize it
to an empty Array:
 
public var textBoxes:Array = [];
 
2. Every time to create a new TextBox, push it into the Array.
For example, inside some method, do
 
var textBox:TextBox = new TextBox();
textBox.foo = bar;
addChild(textBox) ;
textBoxes.push( textBox);
 
3. In any other method, you can refer to textBox[i] to get
the ith one you created.

Wow, that answer will
really help me! :)

What if it's not movies, but some other object that i wanna create 20 times?
I thought it should get inside some kind of Array, but not sure if its this way
too.

i.e. 

var MyTextBox:TextBox= new textBox();

what if i need N instances of that MyTextBox? Should i create an Array before
that? What's the right way to put those  textBoxes into the  Array?

I'm sorry for the basic of my question.... but im quite new to AS3 and OOP,
and i did use and misuse of evals a lot in AS1 and AS2.

Thanx a lot for the help :)

No worries, the equivalent of

eval("movie_ number_" + idNumber);

would be:

this["movie_ number_" + idNumber];

To explain, in actionscript 3 (and in Javascript), these two references are
equivalent:

this.someField = true;
this["someField" ] = true;

trace("the value is " + anObject.button7) ;
trace("the value is " + anObject["button7" ]);

Notice the fact that it's a string. You can also use numbers (this is how
arrays work), and other objects, but with objects the runtime simply calls
.toString() and then goes ahead with the string, IIRC.

Thnx for the psicological
help :)

Tecnically i come from AS1 and AS2 where i used to create multiple copies of
movieclips, and created with a name as:

eval("movie_ number_"+ idnumber) ;

maybe i should need an easy example of how to create multiple objects
dinamically, and most important, how to access them later.

Thnx, u guys are kind ;)

Gordon,

I can live without eval() and associated evilness, but I'd sell my left
testicle for the ability to mark a Proxy as extending or implementing various
classes or interfaces.
Mario - As for this sort
of pseudo-eval that theyou're after, you could definitely cook up something
similar to that without *too much* work, but I don't think it's the correct
solution to whatever the actual root problem is. We need more information as to
context to be more help :)

Why are you lost without eval()?
What would you use it to do? Many developers think they need it when they
really don't; there are often other ways to accomplish what they're trying to
do.

They answer u about eval() cause that was what eval()
was for. I used it so often in AS1 and AS2. Lost now in AS3 without it :(

No, I'm just wondering if there is a way to convert a
string to actual
actionscriptcode. ..
