[flexcoders] Hot news! Adobe Opens iPhone to Flash Developers
This Adobe press release suggests that developers can build Flash apps (Flash CS5) for the iPhone: http://eon.businesswire.com/portal/site/eon/permalink/?ndmViewId=news_viewnewsId=20091005006358newsLang=en Does this mean Flash Builder 4/Flex 4 will support the iPhone at some point? - Alex C
[flexcoders] Re: Hot news! Adobe Opens iPhone to Flash Developers
You're welcome. My boss owns an iPhone and wants everything we build to run on it. So I've been hunting high and low for any way to run Flash on the iPhone without a jailbreak. Some wording from the press release caught my eye: The Apple iPhone SDK license terms do not allow runtime interpreted code, so Adobe is not able to deliver Flash Player in Safari on the iPhone without support from Apple. Applications for the iPhone built with Adobe Flash Professional CS5 do not include any runtime interpreted code. So the apps built with CS5 will not include any runtime interpreted code. Not sure what that means for Flex developers. Is that good/bad/indifferent? - Alex C --- In flexcoders@yahoogroups.com, Vivian Richard kanps...@... wrote: Wow!!! Thanks for sharing the news.

[flexcoders] Re: Hot news! Adobe Opens iPhone to Flash Developers
I'm very curious as to how this applies to Flex. The article didn't mention that, but like you said, maybe someone from Adobe will add something to the discussion and stop keeping us in suspense! It can be a revolution for Flex developers. -Alex C --- In flexcoders@yahoogroups.com, napearson99 napearso...@... wrote: I hope someone from adobe can chime in here. Here's my take. Flex is just a framework built on AS3. This middleware compiler should be able to compile Flex AS3 code into native iPhone code no problem. The new framework should also help reduce the weight of your app and make it run faster. This is really great news. Our skills just got a lot more valuable today. --- In flexcoders@yahoogroups.com, oneworld95 oneworld95@ wrote: You're welcome. My boss owns an iPhone and wants everything we build to run on it.

I'd echo what others have said; I didn't know AS 3 before doing Flex 3. Flex has helped me learn AS. If you spend the time to look at examples on the web and ask questions here, it will all make sense. Programming is programming; you still have iterative and conditional statements; still have functions (now called methods in AS). Just the syntax/architecture are a little different if you're coming from a non-object oriented programming language. - Alex C --- In flexcoders@yahoogroups.com, Alan Rother alan.rot...@... wrote: As another total newbie to Flex and AS, Flex is a great way to learn AS.

[flexcoders] Re: curly braces and functions in mxml
Both in this case do the same thing. Curly braces tell Flex that it should
treat the contents as ActionScript (thus you can Ctrl-click it). It's basically
a function call. Take a look here for an explanation:
http://www.onflex.org/ted/2005/06/property-binding-in-flex.php
In the case of your code, the click property of the Button component converts
the string it receives to a function call automatically; it's redundant to use
the curly braces but it shouldn't hurt anything.

It can be a pain reading/writing binary data regardless if what server side code you use. I'd advise against it unless you need to hide the Word docs from someone coming along and accessing them directly. If you use a good authentication/authorization mechanism to protect the web app, you shouldn't have to store them on the database.

[flexcoders] Re: Best database for Flex
Flex generates a Flash movie (SWF) file that runs in the browser (client side). It's therefore a presentation layer for your application. It calls your Java, PHP, ASP.NET, CFML, etc., server side code to do such things as fetching database records, authenticating/authorizing a user, etc. Your server side code generates data in a format that Flex can understand (for example, valid XML). Flex then consumes that and is able to display it in a datagrid or other control. In this regard, then, Flex is database-agnostic -- it doesn't care where the data it uses comes from. But as others pointed out, you'd want to avoid using MS Access for building web apps; the other databases provide their pluses/minuses. If you need something free, then MySQL/PostGre are good choices. If you're a Microsoft shop, then maybe SQL Server. And of course Oracle is a solid choice for enterprise apps as well. Hope this helps. - Alex C --- In flexcoders@yahoogroups.com, christophe_jacquelin christophe_jacque...@... wrote: Hello, What is the best database for Flex: mySql or SQLServer ?

[flexcoders] Re: Detect exeptions - help!!
Thanks, Alex. It's not hanging on the Flex side -- the server response is never received. Using WireShark (http://www.wireshark.org/), I was able to see it's not hanging at all, but continually sending messages to the Java servlet but getting nothing back in reply. That's what led me to investigate the Java code more closely. The BufferedImage object was receiving some JPG images that it couldn't handle; so it spun away for a while before throwing an exception. For whatever reason, the exception never made it back to the Flex side.

[flexcoders] Re: Detect exeptions - help!!
Found out a solution: The problem was in the BufferedImage object in the Java code. Java's BufferedImage couldn't handle some of the JPG's and was choking. Once I passed the InputStream directly to a method that uses the Java Advanced Imaging API, the problem went away. Using WireShark, I noticed that Flex kept calling the server and getting back a 404 error (therefore it seemed to be hanging, even though it was working behind the scenes). That convinced me it was a problem on the server with Java. - Alex --- In flexcoders@yahoogroups.com, oneworld95 oneworl...@... wrote: I've run into a very frustrating situation and need your help: - Flex uploads a file to the server - The server reads it into a Java BufferedImage object. - However, Java sometimes takes 40 seconds or longer to reply - In some cases it has difficulty reading the file.

[flexcoders] Broken pipe error when uploading file with Flex
I'm getting a broken pipe error in my Java server log when trying to upload a file using Flex. I've got a progress bar attached to the upload and it goes to 100% and then gets stuck while uploading. The file resides on a network drive rather than a local drive. Could this be causing the issue? Is it a security problem?

Is there an event I can listen for to determine what's happening? Help!

[flexcoders] Re: Flex and Java Communication
There are a couple of different ways. To start, you can use a servlet
that generates XML and use an HTTPService in Flex. A more
sophisticated option is to use the free BlazeDS data service tool to
pass objects between Java and Flex.
For the first option, you can create an HTTPService like this,
import mx.rpc.http.HTTPService;
import mx.rpc.events.ResultEvent;
import mx.rpc.events.FaultEvent;
private function getServletXML():void {
var service:HTTPService = new HTTPService();
service.cancel(); // good idea to cancel service first.
service.url = http://myserver.com/MyXMLServlet;;
service.resultFormat = e4x; // Makes XML nodes accessible in
ActionScript
service.contentType = application/xml;
service.addEventListener(ResultEvent.RESULT, serviceResultHandler);
service.addEventListener(FaultEvent.FAULT, serviceFaultHandler);
service.send();
}
private function serviceResultHandler(event:ResultEvent):void {
var myXML:XML = XML(event.result);
// here you'd do something with the myXML object, such as bind it to
a datagrid
}
private function serviceFaultHandler(event:FaultEvent):void {
Alert.show(event.fault.message,Could not read XML servlet.);
}
You can look at this page for an example of connecting a servlet to
Flex:
http://blog.kevinhoyt.org/2007/12/07/flex-to-java-servlet-file-upload/
Another example: http://learn.adobe.com/wiki/display/Flex/2b.+Code+Files

[flexcoders] Re: clear the cache
I've used the random querystring solution as a workaround to the caching issue. It can be something as simple as this, var date:Date = new Date(); service.url = http://myserver.com/whatever?dt=; + date.toTimeString(); -Alex --- In flexcoders@yahoogroups.com, Guy Morton [EMAIL PROTECTED] wrote: Depends on the browser you're using. Clearing the cache is all you should have to do, but depending on whether you are sitting behind a web proxy even that might sometimes not be enough. In my experience, web proxies are a frequent source of developer frustration (especially MS proxies). Sometimes putting a query string on the end of your request can help, eg http://www.yoursite.com/myapp.swf?foo=bar You can then randomise this which can help if you're behind a bad web proxy. In addition, if you have control over the server environment, you can set the no-cache headers when serving your files. This should stop your browser holding onto them (and ought to also stop web proxies doing the same).

[flexcoders] Re: Using XSL in Flex?
The TextArea allows the SPAN tag and the CLASS attribute.
