[flexcoders] Passing data from top level component to lower level component
Hi gang, I'm having a dense moment. How do I pass data through an event from the application level component to a child component? I know how to pass data through an event from a child component to the application component, is it a similar process? Thanks! Steve Good http://lanctr.com
[flexcoders] Flex 3 / AIR: Checking for a window's existence and if it has focus
Hi all, I've built a very basic chat application with flex 3 and packaged it up in an AIR app and I'm wanting to refine it a bit. Currently I can double click a name in my buddy list and create a new window. The problem is if the window already exists and I double click the buddies name again I create another window. What I am trying to do is build in the ability for the buddy list to check if a window has already been created for the selected buddy, and if it has, bring the window forward and set it's focus. I was playing around with NativeApplication.nativeApplication.openedWindows but I'm not really sure how I use this, all I did was trace() the object. Am I on the right track? If so, then what would be my next step, if not then how would I check for a windows existence? Thanks! Steve Good http://lanctr.com
[flexcoders] newbie question
Let me start by saying that I am completely new to Flex and obviously the list. I'll apologize upfront for asking the dumb and obvious questions, but I'm still going to ask them :P So here's a description of what I'm doing and my question. I built an Air app with Flex 3 that posts some form data to a remote cfm file. The cfm file then returns a string. If I watch the app running in the Flex Builder 3 debug perspective I can see the string that's returned. My question is this. How do I get that string and make it available to another function? I want to use the returned string in another post method in the same app. If more details are required I can give them, just holler J and Thanks in advance. ~Steve http://lanctr.com/
RE: [flexcoders] newbie question
Sorry about the subject, I'm not sure why I didn't use something more
descriptive.
Here's a snippet of the code I'm using.
public function postData(){
var urlData:String = "foo=bar";
trace(urlData);
var variables:URLVariables = new
URLVariables(urlData);
var request:URLRequest = new URLRequest();
request.url = "http://domain.com/remoteScript.cfm";;
request.method = URLRequestMethod.POST;
request.data = variables;
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.addEventListener(Event.COMPLETE,
completeHandler);
try
{
loader.load(request);
}
catch (error:Error)
{
trace("Unable to load URL");
}
function completeHandler(event:Event):void
{
trace(event.target.data.resultCode);
}
}
I don't know if this is the best way to do this, I just copied and modified
one of the examples at
http://livedocs.adobe.com/flex/3/html/help.html?content=17_Networking_and_co
mmunications_3.html
The string I'm trying to get is in the last trace, resultCode. FB3 does
show a warning about the function. "-1008: return value for function
'postData' has no type declaration." I don't have a clue what this means.
I have a Flex 3 book on order, so hopefully I can bring my dumb questions
down to a minimum once I get my hands on it.
Thanks!

Welcome, Steve.
First, please use a descriptive subject for all posts, including "AIR", if
you think that might be signficant. There is too much traffic on this list
for anyone to read all posts, so we choose what to read based on the
subject. Subjects like "HELP ME!!!" and "URGENT!!!", and even "Newbie
Question" stand a good chance of being skipped.
Now, for your question, I do not use AIR much yet, but generally, you need
to use a result handler on your data call. That function will be called
when your data returns, and you can then do whatever you need with it. Are
you using RemoteObject to make the call? All the of the RPC protocols
support the result event.

That is ok, but it is the hard way. HTTPService is easier to use.
So you have the string you need in the completeHandler? If so, then I guess
I don't understand your question. If you need to 'save" that string for
later use by some other function, you could declare an "instance" (global)
variable and store it in that. Declare that var outside of any function:
private var _sMyString:String;
then in completeHandler():
_sMyString = event.target.data.resultCode;
Now you can access that value from most anywhere.
That warning is from the function declaration:
public function postData(){
To fix it do:
public function postData():void{
This declares the return type of the function to be "void"

I think I understand, but would love to see an example if you have one.

Send() returns an AsyncToken, which is a dynamic object that is associated with the specific send call, to which you can add any properties that you want. You can include functions if you want, but I usually just send a couple string parameters, on that indicates an id for the call, and an optional one that indicates special processing. In the result handler, you can access the AsyncToken using event.token, then access the values stored in you properties. I use a switch statement to determine what to do with any given result. So all results are in one place. It makes it easy to chain calls, and to maintain that chain. If you are interested, I can post some sample code.
