Flex offline application on cdrom

Hello,
I need to create a cdrom containing a product catalog with
text and images for offline use. Normally I would create it using
flash and an XML-File containing the product data.
I wonder if I could use Flex to achieve the same much easier
Thanks

thanks for your reply !
This should just be a very simple application, with
everything on the CD (xml-data, pictures).
So I have to use a Browser to see the Flex swf ? Or can I
export it as .exe just as I would in Flash and run it with autorun
as soon as the cdrom mounts ?
Other Idea, load flex swf dynamically in a flash created .exe
projector ...
Any suggestions ?

Help needed in migrating Flex 2 application to Flex 3

Hi All,
We are in process of migrating a working Flex 2 application
to Flex 3.
There were no compilation errors when application was
compiled with Flex 3 SDK. But when we start the application, it
throws a script timeout error:
Error: Error #1502: A script has executed for longer than the
default timeout period of 15 seconds.

The application is taking a huge time to 'validate' each
component in the UI and each time we observe a timeout at different
UI component.
Few observations from our end:
1. The application is very straight forward and only thing
complex in it is UI layout. There are a few of complex layouts,
viewstacks and datagrids used.
2. The ‘creationPolicy' at application level has been
set to 'All' because of design. This although is not a standard
practice but this does not help us because the same application
compiled with Flex 2 used to load successfully.
If anybody has faced a similar issue and has some suggestions
please do give us pointers. Otherwise we are left with a lengthier
option of re-factoring the application so that creation policy
defaults to 'auto' and modify the application design.
Thanks in advance,

Is there a way to save data to just one view in Flex Mobile applications?

I am having trouble handling data between views in a Flex Mobile application that I am writing. I know how to pass data from one view to another, but I was wondering if there is a way to save that data to a view, then get more data from another view (in this case it would be the same view that the original data came from) and put that data on the same view without overwriting the original data. I would be glad to post some code if anyone needs to see it.

I think we realise that this is the same question as the other thread.

We have had this issue many, many times before including on the latest 3.6 rev. It appears that when the applicationCache has an update triggered by a new manifest file, the browser may still use only its local network cache to check for updates to the files in the manifest, instead of forcing an HTTP request and revalidating both the browser cache and the applicationCache versions of the cached file (seems there is more than one). I have to assume this is a browser bug, as one should not have to frig with server Cache-Control headers and such to get this to work as expected (and even then it still doesn't sometimes).
The only thing that seems to fix the problem is setting network.http.use-cache to false (default is true) in about:config . This helps my case because we only ever run offline (applicationCache driven) apps in the affected browser (our managed mobile apps platform), but it will otherwise slow down your browser experience considerably.

Porting Flex 2 Application to Flash 6

On a scale of 1 to 10 (11 being impossible), how difficult is
it to port a Flex 2 application to work with Flash 6? I've been
reading up and it appears the oldest version most Flex applications
will work with is Flash 9 due to the inclusion of ActionScript 3.
I read somewhere Flex 1 supported Flash 7. Would Flex 1 or
1.5 support Flash 6? If so, then the question becomes how difficult
on a scale of 1 to 10 (11 again being impossible) is it to reverse
engineering a Flex 2 application to Flex 1.

No. As I recall Flash 7 was the first to use AS2, and Flex 1x
absolutely requires AS2.
This will be a matter of abstracting the functional and UI
designs from the Flex app and implementing them in Flash 6. I don't
really care, but why on earth would you need to do this?

How to create and save a file in flex web application ?

Hi,
I want to create and save a file form flex web application. Is it possible ?
I have done some googling and found that its only possible through file referece, which needs some serverside implementation be called.
Is it not possible with file reference to create and save file directly ?
Can any one suggest how to over come this.
Thanks in advance.

Alex,
code written with the Flex Builder 3 libraries will certainly run in Flash Player 10. However, what you need is not so much the capabilities of FP10 but the library functionalities of the Flex 4 package. And I think that Flex 4 code will only run in FP10 and not 9 (but haven't tested this as at work we have not yet been permitted to upgrade, so there is not a lot of point going for Flex 4!).

How to use custom HTML page in flex web application with out using iframe

Hi all,
I have to import a custom HTML page (that has got links to another html pages) inside my flex web application and i dont want to use IFrame. Can you please suggest me with best example.
Please help me out as i'm new to flex.
Thanks,
Swetha.

Hi, there:
Best thing to do is to start with the default login.html page, and then modify it. The login screen is fairly complex and it's easy to just miss a JS function you need to call. To get to default page, you would need to do one deploy (to simulator or whatever), and then look for login.html page in the temporary Xcode or Android project generated from the deployment. It should be under the "deploy" directory in your JDev workspace.
You can also see all the framework JS files and CSS files that way as well.
We have had customers implementing custom login screen so we know it can work, but they all had to start with the default login screen and then modify it.
Thanks,
Joe Huang

Best practice for auto update flex web applications

Hi all
is there a best practice for auto update flex web applications, much in the same way AIR applications have an auto update mechanism?
can you please point me to the right direction?
cheers

Hey drkstr
I'm talking about a more complex mechanism that can handle updates to modules being loaded into the application ect...
I can always query the server for the verion and prevent loading from cach when a module needs to be updated
but I was hoping for something easy like the AIR auto update feature

Unable to write text in Hindi Language in Flex running application

I am not able to write text in Hindi in flex running application.
I have installed Hindi font by window system CD and all I did for font installation.
But still I am not able to write in Hindi in the running flex application by using Flash Player with all version.

Embedding swf into Flex Desktop Application size/scale problem.

Hello,
I am embedding an swf animation into my desktop Flex desktop application. I am using SDK 4.6.0. I use the SWFLoader to embed the animation:
<s:SWFLoader source="img/mch_anim_1.swf"/>
When I run the application, the animation is loaded and is working, but when I try to maximize the window there is a size/scale bug that happens. The screen stays half-side maximized (maximized to the top, bottom and stays until the middle of the screen by side).
I've published the SWF for Flash Player 8 and Actionscript 2 just to test and there was no problem with the size/scale, but I need to use Actionscript 3.
Any suggestions?
Thanks in advance,
Stefan

I found the problem!
There was a line of code that was auto-generated from using a template out of Flash CS6. The line of code that caused it is:
stage.scaleMode = StageScaleMode.SHOW_ALL;
After deleting it, everything is now working properly.
Greetings!
