LAZIOMATICA – Guida allo Sviluppo Software

Dopo 2 anni di assenza torna l’evento Adobe più atteso dagli sviluppatori web,  il 26 e 28 Maggio 2009 a Milano e Roma. Visita il sito http://www.fromatoweb.it per ulteriori informazioni.

Sezione per il check  dell’autorizzazione:

function loadCompletePrefs (mySO:SharedObject) {

if (0 == mySO.getSize() ) // non è presente l’oggetto nel dispositivo
{
trace(“NO SHARED FOUND”)
// Se size è uguale a 0, è necessario inizializzare i dati:
gotoAndStop(“serial”) // salto alla sezione per impostare i dati..in questo caso l’inserimento del seriale

}
else
{
//mySO.clear();
// Traccia tutti i dati in mySO:
trace(“SHARED FOUND”)
trace( “Prefs:” );
for (var idx in mySO.data) {
trace( ” ” + idx +”: ” + mySO.data[idx] );
if (idx==”md5″) if( mySO.data[idx]==md5)
{
trace(“Autenticazione OK”)
// continua con elaborazione filmato da utente autenticato o autorizzato
}
else trace (“Autenticazione failed”)

}
}
}

// Istanziamo  l’oggetto condiviso:

var Prefs:SharedObject = SharedObject.getLocal(“Prefs”);

SharedObject.addListener( “Prefs”, loadCompletePrefs );

Sezione di scrittura dello SharedObject:

function saveSeriale (mySO:SharedObject) {
mySO.data.name = “Infodemo”;
mySO.data.email = “info@laziomatica.com”;
mySO.data.serial1 = sn01;
mySO.data.serial2 = sn02;
mySO.data.serial3 = sn03;
mySO.data.md5 = md5v;
mySO.flush();
var flushResult = mySO.flush(); // qui salviamo l’oggetto
switch (flushResult) {
case ‘pending’ :
md5.text += “pending”;
break;
case true :
md5.text += “Data was flushed.”;
break;
case false :
md5.text += “Test failed. Data was not flushed.”;
break;
}

}

var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
var keyCodev = Key.getCode();
if (keyCodev == ExtendedKey.SOFT2) {

if (key1.text==sn01 && key2.text==sn02 && key3.text==sn03)
{
md5.text=”OK CHECK”;
_focusRect = false;
//gestiamo lo shared object appena finito il suo recupero…che in questo caso è immediato poichè non esiste

Prefs = SharedObject.getLocal(“Prefs”);

SharedObject.addListener( “Prefs”, saveSeriale );
}
else  md5.text=”NO CHECK”;

}

}

};

// gestore di eventi tastiera
Key.addListener(keyListener);

Questo è tutto.

One of the most common requests for the Flash team is to provide a Webservice component for Actionscript 3.0 like the one Flash has for Actionscript 2.0. Finally, Flash has provided the features in CS4 to allow users to use any Flex components that does not rely on Flex framework such as Flex WebService component and HTTPService.

In the below example am going to demonstrate how users can use Flex WebService in Flash to get countries names and populate them in a Flash DataGrid component.

1. File > New
2. Select “Flash File (Actionscript 3.0)”.
3. Open the Component panel and drag a DataGrid component to the stage and call it “dg”.
5. File > Publish settings and click on “Flash” tab.

6. Click on “Settings” button to launch “Advance Actionscript 3.0 Settings”

7. Click on the “library path” tab

8. Click on “Browse to SWC file” icon and get the “framwork.swc” and “rpc.swc” from the Flex SDK as follow :

You can download FlexSDK and select the above SWC’s from the following location
“sdks/3.0.0/frameworks/libs/”

9. Open the action panel and import the following:

import mx.rpc.soap.*;
import mx.core.*;
import mx.rpc.events.*;
import fl.data.DataProvider;
10. The following 2 lines of code are required if you are using SDK 3.0.0 but not if you are using higher version of SDK

//The following 2 lines to register class for
//Interface”mx.interface::IResourceManager

var resourceManagerImpl:Object = ApplicationDomain.currentDomain.getDefinition(“mx.resources::ResourceManagerImpl”);
Singleton.registerClass(“mx.resources::IResourceManager”, Class(resourceManagerImpl));

11. Now copy the following and paste below the above 2 line of codes

var foo:WebService = new WebService();

foo.addEventListener(“load”, finishedLoading);

foo.loadWSDL(“http://www.webservicex.net/country.asmx?WSDL”);

var myOperation:Operation;

function finishedLoading(evt:LoadEvent):void
{
myOperation = Operation(foo.getOperation(“GetCountries”));
myOperation.addEventListener(“fault”, wsdlFault);
myOperation.addEventListener(“result”, wsdlResult);
myOperation.send();
}

function wsdlFault(evt:FaultEvent):void
{
trace(evt.fault);
}

function wsdlResult(evt:ResultEvent):void
{
trace(evt.result);

var myResult:Object = evt.result;
var len:Number = myResult.length;
var xml:XML = XML(evt.result);
var dp:DataProvider = new DataProvider(xml);
dg.dataProvider = dp;

}

12. Test Movie and you should get a list of all the countries inside the datagrid :
