How can I Access the Flash "Slide class" using flex and ActionScript 3?

Hi,
I hope someone can help me solve a problem...
I'm using the flex SwfLoader to load a flash side
presentation as follows...
<mx:SWFLoader id="ss_slides" source="ss_slides.swf"
width="320" height="240"/>
I would like to access the flash "Slide Class" using flex so
I can make the following call...
Slide.gotoNextSlide();
Anyone know how I can do that?
Would it be through the SwfLoader Object?
Is there another way?
F.Y.I. Here is a snippets about the Slide class from the
Flash 8 help...
Using the Slide class (Flash Professional only)
You use the methods and properties of the Slide class to
control slide
presentations you create using the Screen Outline pane for a
Flash Slide
Presentation, to get information about a slide presentation
(for example, to
determine the number of child slides contained by parent
slide), or to navigate
between slides in a slide presentation (for example, to
create "Next slide" and
"Previous slide" buttons).
You can also use the built-in behaviors that are available
in the Behaviors
panel to control slide presentations. For more information,
see Adding controls
to screens using behaviors (Flash Professional only) in Using
Flash.
Thanks,
Chris S.

Hi Chris,
You cannot access the methods of the Flash 8 movie from Flex.
And you can't do it the other way around either.
The only way to communicate is to create a LocalConnection on
each side.

How to edit/update data into an XML file using Flex and Actionscript

I can read an external xml file, please see the code below:
protected function button1_clickHandler(event:MouseEvent):void
var GrowthChartsDataGrid:XML;
var loader:URLLoader = new URLLoader();
var request:URLRequest = new URLRequest("../GrowthChartsDataGrid.xml");
    loader.load(request);
    loader.addEventListener(Event.COMPLETE, onComplete)
function onComplete (event:Event)
     var loader:URLLoader = URLLoader(event.target);
     GrowthChartsDataGrid = new XML(loader.data);
     GrowthChartsDataGrid.GrowthChartGridView += <Month> {txtMonth.text} <Weight> {txtWeight.text} </Weight> </Month>
     texttesting.text = GrowthChartsDataGrid.toString();
I can read an XML file and can add an extra node and can display it in a text filed. But I want to update the XML file contents which will come from the txtMonth and txtWeight text boxes.
Please any suggestions???

First of all thanks for your quick reply .
I actually want to add another node inthe xml file. Files is at a local location and i can read the file and add an extra node (but I cant store this extra node in the actual XML file). But I want to save XML with the extra node.
For exmaple,
my current xml is:
<?xml version="1.0" encoding="utf-8"?>
<GrowthChartGridView>
    <Month> 1
    <Weight>3.5</Weight></Month>
<Month> 2
    <Weight>3.9</Weight></Month>
<Month> 3
    <Weight>4.5</Weight></Month>
</GrowthChartGridView>
and at run time, I can create a new node using the data from two textboxes at button click event.
     GrowthChartsDataGrid.GrowthChartGridView += <Month> {txtMonth.text} <Weight> {txtWeight.text} </Weight> </Month>
Now what I want to do is, I want to add this node back in to my XML. Therefore, the result I am looking for is, my local XML should update like this.
<?xml version="1.0" encoding="utf-8"?>
<GrowthChartGridView>
    <Month> 1
    <Weight>3.5</Weight></Month>
<Month> 2
    <Weight>3.9</Weight></Month>
<Month> 3
    <Weight>4.5</Weight></Month>
<Month> {txtMonth.text} <Weight> {txtWeight.text} </Weight> </Month> //I can read data from text boxes so its fine but I can not store this in to                                                                                                          my original XML
</GrowthChartGridView>
Thanks

Flex and BlazeDS Compile for Deployement

Hi,
I've been following the Flex + BlazeDS tutorial on the Message Service from adobe to start learning working with blazeds. Everything worked out great on the local server of course but I got stuck when it came to moving the files to a remote server. I've looked around quite a lot and found out it's because the compiler feeds the services-config.xml upon compile and at lease in my case won't take and external file. The solution everyone has been posting on the net is writing the channels in actionscript within flex and feedin it the valid endpoint that would be found in the xml configuration file. That's all nice and dandy but everyone has been talking and showing examples of this being done for RemoteObject and I haven't managed to find any examples for Messaging.
Can anyone help me out with an example on how to deploy my application to a server? (either by coding the channels in AS or otherwise) The application itself is pretty basic...
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
      xmlns:s="library://ns.adobe.com/flex/spark"
      xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="200" minHeight="480" creationComplete="consumer.subscribe()" width="250" currentState="EnterName">
<fx:Script>
<![CDATA[
   import mx.messaging.events.MessageEvent;
   import spark.events.TextOperationEvent;
]]>
</fx:Script>
<s:states>
<s:State name="Chat"/>
<s:State name="EnterName"/>
</s:states>
<fx:Declarations>
<s:Producer id="producer" destination="chat"/>
<s:Consumer id="consumer" destination="chat" message="messageHandler(event.message)"/>
</fx:Declarations>
<fx:Script>
<![CDATA[
   import mx.messaging.messages.AsyncMessage;
   import mx.messaging.messages.IMessage;
   private function send():void{
    var message:IMessage = new AsyncMessage();
    message.body.chatMessage = user.text + ":" + " " + msg.text;
    producer.send(message);
    msg.text = "";
   private function messageHandler(message:IMessage):void{
    log.text += message.body.chatMessage + "\n";
]]>
</fx:Script>
<s:Panel title="Chat" width="100%" height="100%">
<s:TextArea id="log" height="377" x="10" y="10" width="228" includeIn="Chat"/>
<mx:ControlBar width="246" height="52" x="1" y="395" includeIn="Chat">
   <s:TextInput id="msg" width="100%" enter="send()"/>
   <s:Button label="Send B" click="send()"/>
   </mx:ControlBar>
<s:TextInput includeIn="EnterName" x="60" y="177" id="user" />
<s:Button includeIn="EnterName" x="87" y="207" label="Start Chat" id="chat" click="chat_clickHandler(event)"/>
<s:Label includeIn="EnterName" x="57" y="157" text="Please Enter Your Name"/>
</s:Panel>
</s:Applicatio>
And besides that in the messaging-config.xml file on the server a destination with the id="chat" is created and that's it.
Any help or pointing in the right direction will be greatly appreciated.
Thank you,
Nick

Update:
Ok...I finally figured out that by replacing the tokens in the services-config.xml file with the physical address of the server everything works.
Anyway...this means the application needs to be compiled everytime it is moved to a new server or even a different folder on the same server for that matter. Is there any way to pass the {server.name}, {server.port} and {context.root} tokens to the application at runtime for messaging?
Thanks,

Flex and HTML display shift in Safari in Mac OS

When a popup is displayed in Flex app, the Flex display gets shifted down in Safari in Mac OS alone. However, even if the display is shifted down, the controls seem to be in the correct position. For example, for clicking a button, the cursor has to be some pixels above the shown display. Not only the Flex display shifts down. HTML Links display also shifts down along with Flex and Links are clickable some pixels above the display.
The problem happens only while triggering the Flex popup display in long flex screen. On a Flex screen within the browser height, with the same actionscript and Javacsript code, there is no problem.
This works fine in all other browsers including Safari in windows.
Has anyone faced this scenario? Any help will be highly appreciated.
For the popup to be displayed in center of viewable area, the following code is used.
callLater(SMBObjectUtil.changePosition,args);
In SMBObjectUtil.as file,
public static function changePosition(x:int, y:int, obj:UIComponent):void {
     var yPos:int = ExternalInterface.call("findScrollTop");      var winHeight:int = ExternalInterface.call("getWindowHeight");
     var appHeight:int = Application.application.height;
     var objectWidth:int = obj.width;
     var objectHeight:int = obj.height;
     var calculatedX:int = 0;
     var calculatedY:int = 0;
     if(Application.application.width>obj.width) {
          try {               calculatedX = (Application.application.width - obj.width)/2;
               if(yPos <= 0){                    calculatedY = ((winHeight-objectHeight)/2-100)>0?(winHeight-objectHeight)/2-100:50;
else if(yPos<=(appHeight-winHeight)){                    calculatedY = (((winHeight-objectHeight)/2)+yPos-100)>0?((winHeight-objectHeight)/2)+yPos-100:50;
else if(yPos>(appHeight-winHeight)){                    calculatedY = appHeight - objectHeight - (winHeight-objectHeight)/2;
          catch(e:Error){          }
     }else {
obj.x = calculatedX;
obj.y = calculatedY;
Javascript functions used are:
function findScrollTop()
var ScrollTop = document.body.scrollTop;
if (ScrollTop == 0)
   if (window.pageYOffset)
    ScrollTop = window.pageYOffset;
   else
    ScrollTop = (document.body.parentElement) ? document.body.parentElement.scrollTop : 0;
return ScrollTop;
function getWindowHeight()
var y = 0;
if (self.innerHeight) {
   y = self.innerHeight;
} else if (document.documentElement && document.documentElement.clientHeight) {
   y = document.documentElement.clientHeight;
} else if (document.body) {
   y = document.body.clientHeight;
return y;

Found a fix for this. CallLater() was giving the problem in Safari. Once I removed CallLater and directly called my function, the problem was resolved.

Flex and Coldfusion error handling

Hello! I was wondering if someone could point me in the right direction regarding error handling in a Flex app thats using an HTTPSERVICE RPC to a Coldfusion component.
If a user is entering form data in Flex and clicks submit... the data is sent via the HTTPSERVICE send method as XML to the CFC. But what if there is a Coldfusion SQL insert statement error? Say a user enters a character in a number field (now i know the best thing to do would be to have actionscript ensure that the values entered are numbers but lets keep that aside just for this example). How could I alert the user to let them know the CFC encountered a SQL error? Or better yet... alert them that everything went "A" ok and their data was successfully submitted.
I originally thought to put CFTRY and CFCATCH around the CFC code. I could do that fine, but had trouble passing back a message string so that FLEX could use it in an Alert.Show window.
Thanks!

Hey Mike,
Sorry after I posted I thought "this may be a question for CF guys as well".
I definitely use and love RemoteObjects. Its great for binding to datagrids and to run SQL to return data from the server back to Flex. I've struggled with successfully passing variables from Flex to CF using RemoteObject though. Say a dataform with 5 text fields & 2 combo box dropdowns.
I think you may have forgotten to post the link to the article for me to read... i didnt see it in your last post?
Thanks!

Code beautifier for MXML and ActionScript?

How do people reformat ugly code in FlexBuilder? I can eaisly
format my Java, JSP, and XML in the same Eclipse environment, but
why not MXML and ActionScript? I am very surprised this feature is
missing. It's quite common that I copy code snippets from somewhere
to FlexBuilder which are not well formatted.

Hey guys, Be patient...
Don't forget the years of Java development that have advanced
Eclipse, not counting the 40 mil or so in prior development that
IBM donated when they ported and open sourced their Visual Age
product line. I used VA it back in 96 and it was slow and clunky,
and never would have sold against Borland's Java products.
I'm sure the decision was consciously made by Adobe product
management to get core feature functionality out and concentrate on
other stuff for the next release.
The FLEX team has done a great job and for some who have ever
been under their delivery schedule for the size of this
undertaking, many can appreciate how well they have done.
Also, considering that many eclipse plugins that are free are
worth what you pay for them (I have tested quite a few), the paltry
$700 bucks for FLEX and the fact that it has a great debugger and
profiler makes it worth it.
One final opinion, no matter what anyone says, software is
not free. You pay in time, learning curve, more time, and
sometimes, just plain old tail chasing!
I'm not really being critical, both of you have valid points,
just be patient, they'll get there.

Flex vs ActionScript

Hi all,
Perhaps I am confused but here's my situation: I'm trying to build a Flash video player for compatibility with IE. I built a simple on in Flex using the Spark components but compiled, it comes to 41k without static linking and 300k+ with static linking.
I have seen some implementations in ActionScript alone and their implementations are 20k-ish flat.
I generated the report from the compile in Flex and it includes a lot of libraries. My questions are:
1. Can anyone explain why these libraries are need and if I can remove them to reduce my filesize?
2. Without static linking and the 41k file size, if a user hits my site for the first time, does it only download 41k or does it download the full 300k? Also, where does it download the libraries that it needs? from Adobe?
3. Is there anyway that I can build a Flex application with pure ActionScript? Or how would I go about building an ActionScript video player and compile it using Flex?
Thanks!

Frameworks carry a price. The ability to just have scrollbars show up by
setting a property is weight the every application carries. If you use the
Microsoft Foundation Classes, an app for HelloWorld is not 2k as if you
coded it by hand in C.
Therefore:
1) you can hand code stuff and not use flex
2) 41K if they already have the RSLs which most folks should
3) hand coding.

Getting started with flex and Eclipse 3.1?

Hi all,
Im a java Eclipse RCP developer and I wanted to work on some small apps using flex.
I have been searching around on the web for instructions on how to get everything set up, but most of them seem to skip a few steps.
I am using Eclipse ganymede (3.1), and have downloaded the flex sdk. Is there a plugin or something for flex that creates the proper perspectives in eclipse? Or what exactly do I need to do?
Also, I see that flex uses mxml, if I want to use flex and java as opposed to flex and php or coldfusion (the only examples I saw) is that possible? I guess Im slightly confused as to what exactly I am writing this app in... java? Actionscript? Php? ??
Basically my goal is this:
Use eclipse 3.1 (not flex builder)
Write an RIA that can also use AIR
Connect to a MySQL database on the backend
I have very little experience (or need) for J2EE, but maybe I should use it?
Can anyone point me to a good tutorial that will get me going to achieve my goal? Or tell me what exactly I need to install, and how to put it together?
Thank you!

You need Flex Builder plugin version.
Trial version here:

Im confused about Flex and Flash?

flex uses Actionscript to develop internet application.
Flash also uses Actionscript to do that. now why i should use
Flex if both using the same language.
is it because Flex has more class libraries ?
when a company or someone asks me why we need to use Flex
instead of Flash , what is the answer for that ?
thanks

IMHO I would say:
Flex is programmers approach to develop apps while
Flash is designers approach .
I cant stand programing and dealing with timeline at the
same time so for me Flex is the way to go.

Open source debugger for Flash, Flex and AIR

As developers at De Monsters we weren’t totally happy
with the current Flash, Flex or AIR debuggers out there. So we
decided to create our own debugger called De MonsterDebugger. Today
we’ve got a great new version that we want to share with the
community for free.
Interface
screenshot
De MonsterDebugger started out as an internal tool that
helped us with the development of different ActionScript 3
projects. The past several months we’ve been working on a new
version of this internal tool. With this new version you can
explore your live application, adjust properties and run methods
all at runtime. You can trace objects of any type (String, Array,
XML or even custom classes) to De MonsterDebugger and it will show
the complete structure of that object in an easy-to-read tree
structure. De MonsterDebugger is made with Adobe Flex and brought
to the desktop with Adobe AIR.
Because De MonsterDebugger isn’t our core business
we’re giving it away for free! All the sourcecode is open
source available under the GNU General Public license.
Enough talking!
Here’s all the information you need:

Flex and E-Commerce

I have recently created a e-commerce build that works on XML httprequests.
Currently i have created the XML feed creators for Oscommerce.
You can see a working demo here
Let me know what you think, this is my first post on this forum so hello to everyone!

Great! Thanks Kenny. So the approach to making the gateway
connections would be similar to working with Actionscript in that I
would still be calling server-side scripts to handle the back-end
work?
Anyone have a recco on which technology would integrate best
with Flex AND be a great solution for an E-Commerce site? Can
someone provide their opinion on the ideal approach?

Problem in creating client side PDF with image using flex and AlivePD

I need a favor I am creating client side PDF with image using flex and AlivePDF for a web based application. Images have been generated on that pdf but it is creating problem for large size images as half of the image disappeared from that pdf.I am taking the image inside a canvas . How do i control my images so that they come fit on that pdf file for any image size that i take.
Thanks in advance
Atishay

I am having a similar and more serious problem. It takes a
long time to execute, but even attaching a small image balloons the
pdf to 6MB plus. After a few images it gets up to 20MB. These are
100k jpeg files being attached. The resulting PDF is too large to
email or process effectively. Does anyone know how to reduce
size/processing?

How do I save a file to a server using flex and coldfusion?

How do I save a file to a server using flex and coldfusion?
On the CF side I might need to use this:
<cffile action="UPLOAD" filefield="Filedata"
destination="#expandpath('..\somepath)#"
nameconflict="overwrite">
And on the flex side I might need to use something like this:
var sendVars:URLVariables = new URLVariables();
sendVars.action = "upload";
var request:URLRequest = new URLRequest();
request.data = sendVars;
request.url = _strUploadScript;
request.method = URLRequestMethod.POST;
_refUploadFile = new FileReference();
_refUploadFile = _arrUploadFiles[_numCurrentUpload].data;
_refUploadFile.addEventListener(ProgressEvent.PROGRESS,
onUploadProgress);
_refUploadFile.addEventListener(Event.COMPLETE,
onUploadComplete);
_refUploadFile.addEventListener(IOErrorEvent.IO_ERROR,
onUploadIoError);
_refUploadFile.addEventListener(SecurityErrorEvent.SECURITY_ERROR,
onUploadSecurityError);
_refUploadFile.upload(request, "file", false);
I just don't know how to put it all together in Coldfusion.

try this...
