A good friend of mine, Cliff Hall, is most known for the PureMVC framework which was inspired by his his lack of love for the Cairngorm framework. Well, Cliff apparently was irritated by the inability to create licensed products with Flex and AIR too, so he did something about it. Zarqon. He has created very useful tool for creating a licensed Flex and/or AIR applications. How you implement your app is totally up to you, Zarqon just helps you easily issue and validate licenses.

Are you a software skeptic, me too! No worries, there a free 30 day trial license that will allow you to fully evaluate the product and make a decision about whether it’s right for you.

It is now in “beta”, but if you begin implementation of a Zarqon-licensed product within the trial period that you plan to launch, let him know and you just may get a free license. Even if you do have to buy a license, it won’t set you back but $25.

I’m going to start my testing immediately and I’ll let you know my  thoughts later.

You can read all about it and sign up for the Beta at http://zarqon.net

Open a terminal window.

But no matter how many applications or who I’m talking to, I always stress the importance of securing proprietary information. By securing, I mean don’t put it in your application. Unless your are encrypting your application and decrypting at runtime, you are subject to a decompiler exposing your secrets.

There are Flash decompilers that will take any SWF and give you the source:
Trillix Flash Decompiler is one of the best commercial tools I’ve found.
I’ve even seen guys decompile, make changes and then recompile a Flex app. This is scary! Say goodbye to licensing software in Flash.

But HP just released a tool that has caught my eye as well. (Note: I have not tested this tool) It claims to decompile and test for security weaknesses. It’s called SWFScan and it’s a free Windows based tool from HP.

If security in a Flex or Flash based application is a concern for you, you must look at these tools. If security is not your concern, look anyway.

Here is a little Q&A about CFUnited and me.

1. Have you spoken at CFUnited in the past?  What would you tell someone who hasn’t been to CFUnited before?

Yes, I have spoken at CFUnited in the past. And I’d have to equate it to seeing your favorite band in a small venue. Same great talent, but not nearly as crowded allowing you to easily network with so many very talented people.

2. Why should people attend your session(s)?

If you have been wondering about, thinking about or just plain curious about Adobe AIR, my session will clear the air… uh, no pun intended.

3. Do you have any projects in the works that you will be revealing at CFUnited?

I have been doing quite a bit in the mobile space, actually more of an add-on to some of our AIR development projects. So look forward  to ways to take your application to iPhone, Symbian and Android.

4. Besides your topic, what other sessions are you looking forward to?

I know I’ll get in trouble for this, but its not the sessions to which I really look forward. Its the one on one conversations that I’ll have with people from all over that help me solve problems and come up with new ideas. That is what I’m looking forward to. Oh and the sessions help me identify who I’d like to meet.

5. Where can people find you at CFUnited?  (At the bar, networking, working, in your room, etc.)

Networking.

6. What’s the latest news with you? Has anything changed since last CFUnited?

Since On3 is all about helping organizations grow their own Flex developers, we have opened a new training center in Denver, CO.

7. When you are not working what do you like to do in your free time?

Mountain Bike in the Spring thru Fall, Ski during the Winter

Of course there are three restrictions. You must attest that you are:

1. Unemployed
2. Using it for personal use
3. Not using it for commercial or production use

UPDATE: The program was suspended, the last I looked, due to the high volume of applicants. But keep checking. You never know.

I was working on a JavaScript-based AIR application (some refer to this as an AJAX-based application) recently where they wanted to use AMF, but didn’t want to hide a SWF in it to facilitate the AMF communication. Since there are other Flash Remoting gateways available, like openAMF and AMFPHP, it would be great if I could just use a JavaScript library to do the communication with those gateways.

If you look at examples in Flash that do this type of connection, you’ll notice that they use a NetConnection class. Guess what?! That class is also available in the JavaScript API for AIR. Yes, its that simple!

So with a simple refactoring of the same code from Flash, I was able to get my JavaScript-based AIR application to communicate with a Flash Remoting gateway. This example assumes you have installed a Flash Remoting gateway somewhere, that you replace [my_flash_remoting_gateway] with the gateway root and you’ve created a class with a method that you can invoke.

<html>
<head>
<title>JavaScript-based Flash Remoting</title>
<link href="sample.css" rel="stylesheet" type="text/css"/>
<script type="text/javascript" src="lib/air/AIRAliases.js"></script>
<script type="text/javascript" src="lib/air/AIRSourceViewer.js"></script>
<script type="text/javascript">
function doAMF()
{
var netConnection = new air.NetConnection();
netConnection.connect("http://[my_flash_remoting_gateway]");
var responder = new air.Responder(onComplete, onFail);
netConnection.call("HelloWorld", responder);
}
function onComplete(results)
{
alert( results.length );
}

function onFail(results)
{
alert(results)
}

</script>
</head>

<body>
<h3>Get data over AMFPHP</h3>

<ul>
<li>Has access to AIR APIs:
<input type="button" onclick="doAMF()" value="Make AMF call"/>
</li>
</ul>

</body>

</html>

Here is an example class in PHP:

<?php
class HelloWorld
{
function HelloWorld()
{
$this->methodTable = array
(
"say" => array
(
"access" => "remote",
"description" => "Pings back a message"
)
);
}
}
?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
viewSourceURL="http://www.robrusher.com">
...
</mx:Application>

Nice!

UPDATE: For Flex Builder 3 they added a simple selection option that will include the source for you. Select from the menu bar Project > Export Release Build… And then in the dialog, check the box for including source and select the objects you’d like to include.

Thanks Jason for reminding me to update this post.

This class is for those who already know Flex and ActionScript, basically you should have experience with classes and creating event listeners.

I’ve taught it at Adobe MAX in Chicago and will teach it at Adobe MAX in Barcelona. The reviews have been very positive (the last one ended with an ovation).

You should see the class appear on Adobe training partner sites later this year.
