As in, are you possible creating new instances of classes when you thought you were using an instance that was created previously.

RE: [flexcoders] Applications forgetting variables
Create a new sample application that shows the problem you are having. It is important to have an entire sample that we can run immediately, and that has only the minimum code required to show the issue.

RE: [flexcoders] Applications forgetting variables
The difference between
these two approaches is scope.
In your first example u
create a variable on the instance of the class u are working in. This variable
exists as long as that instance has a reference somewhere in the
application.
In the second example u
create a variable inside a function definition. This means that at the }, the
end of the function this variable is destroyed.

forgetting variables
I can not help but feel I have ran in to more problems than neccessary
because my flex applicaitons forget variables. I mean I know from a code
standpoint I am doing the right thing when I write my code but I think it
forgets variables and I think this is causing me more stress than need be. What
I want to know is how does someone go about making sure it does not forget
variables I mean is this a way to do it:
If I have a function and a variablethat looks like this say:
public var age:Number
public function compute(){
age = 23
}
but lets say that for some odd reason when you get to the compute function
it keeps forgetting the age variable will this solve it to write the function
like this:
public function compute(){
var age:Number
age = 23
}
If there is any other suggestions let me know

Re: [flexcoders] Applications forgetting variables
Ok assuming your right and again I hope this is not another silly question but what does a local variable look like and what does an instance variable look like? To me I just thought all variables were just like this public var name:String you know things like that Yahoo!

Re: [flexcoders] Applications forgetting variables
It all depends on WHERE you declare the variable. In the first case, you were defining your var outisde of the function, which should keep its value even when the function is through running. If you declare the var inside the function, however, that variable will be destroyed when that function is through running. You really should read a tutorial or chapter on Variable Scope, and post your code here, because you're not giving us much to work with.

RE: [flexcoders] Applications forgetting variables
An instance variable is inside a class,
but outside that class's methods. A local variable is inside one of the
methods.
public class MyClass
{
var
myInstanceVariable:String;
public function
myMethod():Void
{
var myLocalVariable:String = Gordon;
trace(myLocalVariable);
}
}
Questions like this are definitely not
silly, but they're questions about object-oriented programming, not about Flex
per se. You would face similar issues with other OO programnming environments.

RE: [flexcoders] Applications forgetting variables
Can you be more specific about what you
mean when you say it keeps forgetting, or post a tiny but complete
mx:Application that demonstrates the problem?
The meanings of 'var age' in your two
examples are very different. Your second example would forget that
you set age to 23, because you are setting a local (or temporary) variable in
the compute function, and local variables go away when the function they are in
returns. The first example would not forget the 23 because you are
setting an instance variable on whatever the 'this' object is; instance
variables last as long as the object itself.

It is 99.% likely that you have a coding error, but I can't tell you what it is if you won't post malfunctioning code. : ) It certainly sounds like you are declaring a local variable when you should be using an instance variable. - Gordon From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, May 24, 2005 9:58 PM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Applications forgetting variables I will set a variable to be a certain amount in one function then call it in a later function and its completely forgotten it Yahoo!
