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"

Subject: 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_an
d_communications_3.html
<http://livedocs.adobe.com/flex/3/html/help.html?content=17_Networking_a
nd_communications_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!

Subject: RE: [flexcoders] newbie question
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.

Subject: [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 :-) and Thanks
in advance.
