Im trying to send three variables (fname, lname, and email) to append them to the URL string like this http://www.whatever.com?address=&firstname=&lastname=&email= and it traced as "Message Failed" I wonder what I did wrong with this code.
in Flash 'fname_txt', 'lname_txt', and 'email_txt' are the instance names of the Input Text
import flash.events.MouseEvent;
import flash.net.URLRequest;
import flash.net.navigateToURL;
mcButton.addEventListener(MouseEvent.MOUSE_UP, onClick);
function onClick(e:MouseEvent):void {
var scriptRequest:URLRequest = new URLRequest("../index.aspx");
var scriptLoader:URLLoader = new URLLoader();
var scriptVars:URLVariables = new URLVariables();
scriptLoader.addEventListener(Event.COMPLETE, handleLoadSuccessful);
scriptLoader.addEventListener(IOErrorEvent.IO_ERROR, handleLoadError);
scriptVars.fname = fname_txt.text;
scriptVars.lname = lname_txt.text;
scriptVars.email = email_txt.text;
scriptRequest.method = URLRequestMethod.POST;
scriptRequest.data = scriptVars;
scriptLoader.load(scriptRequest);
function handleLoadSuccessful($evt:Event):void
{
trace("Message sent.");
}
function handleLoadError($evt:IOErrorEvent):void
{
trace($evt); <----------------UPDATED
}
fname_txt.text = "";
lname_txt.text = "";
email_txt.text = "";
}

I would like to know what projects hosted on Google Code that have the most stars, especially when searching by label, like this:
https://code.google.com/hosting/search?q=label%3aAndroid
Sort by stars is not supported on the project search page. Was able to write some page scrapping code to get the required information.
Hope it helps.

I would have say use &sort=stars as they do in the support of google code but it doesn't work well. I'm not sure it's possible unfortunately...
using Adobe Flash Builder 4.6
the below code is what I am using to try to get actionscript to populate a list a from sqlite table. It brings back the correct number of records but it shows the results as:
[object Object]
[object Object]
[object Object]
Can someone tell me what I may be doing wrong?

conn.addEventListener(SQLEvent.OPEN, openSuccess);
//conn.addEventListener(SQLErrorEvent.ERROR, openFailure);

}

//conn.removeEventListener(SQLErrorEvent.ERROR, openFailure);
getData();
}
private function getData():void
{
var select:SQLStatement = new SQLStatement();
select.sqlConnection = conn;
//select.text = "SELECT id, txtState, txtAbbrev FROM " + strGetCurrentTableName;
select.text = "SELECT id, txtState FROM lkStates";
select.addEventListener(SQLEvent.RESULT, selectResult);
//select.addEventListener(SQLErrorEvent.ERROR, selectError);
select.execute();
}
private function selectResult(event:SQLEvent):void
{
var result:SQLResult = null;
result = event.currentTarget.getResult();
if(result.data)
{
list.dataProvider = new ArrayCollection(result.data);
}
}
This worked for me, I tried to match your variables for example.
var result:SQLResult = select.getResult();
list.dataProvider = new DataProvider(result.data);
if(result.data)
{
for(var i:int = 0; i < result.data.length; i++)
{
var tState:Object = result.data[i];
trace("var1 "+tState.var1+"var2 "+tState.var2...etc)
}
}
You need to set labelField to your list to a field name in your table so that it can appear in the list. In the declaration of your list type : labelField = "txtState" and you will get the information from this field.
I have a web application developed using flex and cakephp. My client need to make a desktop application of that web application using Adobe Air. The conversion of the flex to Air is done successfully. I the flex application the communication of flex and cakephp is handled using a remotes controller.
In air application I have a problem of authenticating the user with cakephp default user authentication. Can anyone help me to find a solution for this?
i suggest you to send your user credentials via POST to your cakephp backend.
A login function in your UsersController would look something like this:
public function login() {
if ($this->Auth->login()) {
$this->serviceResponse(Status::SUCCESS);
} else {
$this->serviceResponse(Status::AUTH_FAILED);
}
}
// this is just an example out of my appcontroller to send json responses
public function serviceResponse($code, $data = array()) {
$response = compact('code', 'data');
$this->response->body(json_encode($response));
$this->response->send();
$this->shutdownProcess();
exit;
}
// I also defined a class for return statuses
class Status {
const SUCCESS = 'success';
const ERROR = 'error';
...
}
Basically, you want to send the validation request as an ajax request. To do that you need to modify headers, capture session ids through cookies and post them to keep the session alive. It expects a JSON object returned from Cake.
I've created a couple Flex classes that achieve just this for a Flex Mobile App and a CakePHP backend. It should work the same for your needs.
It's in two files, the AutoValidationUrlRequest.as extends the HeaderURLRequest.as file. I'm not positive but there may be a couple variables to change, but overall it works very well and probably won't take more than a couple changes to get it working on your app.
To use it, simply create a new AutoValidationUrlRequest object and add an event listener on the headerUrlRequestComplete Event and then run AutoValidationUrlRequest.send(...) to POST. there is also a handy method called convertToPostVars for easy Cake Friendly Post variables.

Also, using this with my forked version of Jose Gonzalez's CakePHP ajax_controller plugin is really handy. It basically takes any Ajax Request and converts all view variables and outputs them into a JSON object, no rendered view. Otherwise, if you're not using an ajax request, Cake will render the views normally. Good Luck!
i wanna make a dynamic tree using a lazy loading ,each time i open a folder the tree sends a http request to the server, in this script i'm using just static text to test the tree but , i'm getting in the label of the root all the XML text assigned to the dataprovider, then when i open the root folder i got the childs with good labels , and openitem and closeitem events do not fire how could i make them work , any help is welcome

I am getting Syntax Error 1202 (Access of undefined property connection in package model) in the following code while trying to access the model.connection property. I don't see any reason why this would appear, can anyone see something I may be overlooking?
Model.as
package valueObjects
{
import flash.data.SQLConnection;
import mx.collections.ArrayCollection;
public class Model
{
public var connection:SQLConnection;
public var albums:ArrayCollection = new ArrayCollection();
public var albumItems:ArrayCollection = new ArrayCollection();
public var selectedAlbum:Number = 0;
public var selectedItem:Number = 0;
public function Model()
{
}
}
}
And the actual code in my default mxml file, init() is called on initialize
import model.ModelLocator;
import mx.core.mx_internal;
import valueObjects.Model;
protected var sqlConnection:SQLConnection;
private var model:Model = new Model();
protected function init():void
{
createDb();
navigator.firstViewData = model;
}
protected function createDb():void
{
sqlConnection = new SQLConnection();
sqlConnection.open(File.applicationStorageDirectory.resolvePath("Oxford.db"));
var stmt:SQLStatement = new SQLStatement();
stmt.sqlConnection = sqlConnection;
stmt.text =
"CREATE TABLE IF NOT EXISTS albumItems (" +
"id INTEGER PRIMARY KEY AUTOINCREMENT, " +
"album INTEGER, " +
"name STRING, " +
"dateAdded DATE)";
stmt.execute();
model.connection = sqlConnection;
}
The issue here is that you have a package and a variable named 'model'. When you try to access the variable named model, it thinks you are referring to the package. If you correct this naming collision, you will see that this issue is fixed.
