How can i call javascript function with out internet connection?
I have trying to call javascript function through ExternalInterface. But flash player recomonding to have internet connectivity. i have allredy used allowscript="always" .
first, allow the folder that contains your flash files to connect to the internet by adjusting your security settings:
http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04a.ht ml
then try the following in a swf and open the published html in your browser to test:
import flash.external.ExternalInterface
ExternalInterface.call("function(){alert('test');}")

Hey floridiansue,
Do you have an installed email program such as Microsoft Outlook? If your email is through an online login, such as Gmail, etc, then one will have to create an email association with a program such as Microsoft Outlook on the PC for this Scan to Email system to function.

Calling was a good suggestion. Apple Care had the wrong email address and changing
it for the Apple Discussions is not linked to Apple Care. The lady at Apple Care corrected
the email address on my record.

I purchased an ablum thru itunes on my phone and it says i purchased the songs on itunes but when i go on my music it says i have to repurchase all the songs how can i get the songs with out havin to pay again
Whether you can redownload music depends upon what country that you in. If you are using your computer's iTunes then does music show in the Purchased link under Quicklinks on the right-hand side of the iTunes store home page (on your phone you might be able to redownload media via the Purchased tab in the iTunes store app) ? If music shows there, but not that album, then check to see if it's hidden : http://support.apple.com/kb/HT4919
If you aren't in a country when you can redownload music and it's still on your phone then you should be able to copy it over from the phone via File > Devices > Transfer Purchases. -

HT5622 how can i download free apps with out a credit card
how can i download free apps with out a credit card
If you only want the free apps, take a look here:
http://support.apple.com/kb/HT2534
Read the steps carefully as the order in which you follow them is critical. Note that you can do this only when creating a new Apple ID. You cannot use an existing ID.
You will of course not be able to get anything other than the free apps without entering in some sort of payment method (credit card, prepaid iTunes card, gift certificate, etc.)

How can we call actionscript functions from js
hi
how can we call Action script function from js file . i
tried ExternalInterface. add Callback() .but it throws an error .is
there any other chance to call action script method .thnx in
advanceangadala,
some people have found it is good to include the full
qualification path, ie
if (flash.external.ExternalInterface.available)
flash.external.ExternalInterface.addCallback("ext_method_name",int_method_name);
} // if (flash.external.ExternalInterface.available)
There are also browser differences which affect how you find

Can creative cloud be used with intermittent internet connections?
Hi,
I have a number of clients that like to "work on the ice" if you know what I mean. They ar eall ice fishermen or work in that industry. Can CC be used with intermittent internet connections?
Thanks,
VanHi Van,
I copied this from the Creative Cloud FAQ:
http://www.adobe.com/products/creativecloud/faq.html
Do I need ongoing Internet access to use my Adobe® Creative Cloud™ desktop applications?
No. Your Creative Cloud desktop applications (such as Adobe® Photoshop® and Illustrator®) are installed directly on your computer, so you won't need an ongoing Internet connection to use them on a daily basis.
An Internet connection is required the first time you install and license your desktop apps, but you can use the apps in offline mode with a valid software license. The desktop apps will attempt to validate your software licenses every 30 days.
For annual members, you can use the apps for up to 99 days in offline mode. Month-to-month members can use the software for up to 30 days in offline mode.
Hope that helps,

How can i call a function of a swf-file which is embedded as a Resource in 3D-Annotation?
Hi.
I use a Flash-menu as an embedded *.swf in a 3D-Annotation. Now i want to trigger one of the ActionScript-Function out of the 3D-Annotation.
How can i get access to that function?
Cause of it is embedded, the callAS() Methods still not possible. But how else can i do that?
Can u give me a simple example? How is the usability of Flashvariable in the Ressource-Tab of 3d-Annotation?
Kind regards
FlorianIt depends to some extent on how your SWF has been bound to the 3D scene. If you have bound it using a script, then you have a FlashMovie object that has a .call() method - but if you've attached it to something using the binding option on the Resources panel you will need to collect a reference first. If you know you are going to talk to the SWF it's best to bind it using JavaScript.
Let us assume you have a SWF in the resources collection but it's not bound to anything. In the 3D scene there is an object called 'cube' on which the SWF must appear as a material, and the SWF has declared a function to the ExternalInterface engine that is called "myFunction", which expects a string as a variable. Here's what you would put in the script attached to the 3D scene:
var fm = new FlashMovie("demo.swf");
var matl = scene.meshes.getByName("cube").material;
matl.useFlashMovie(fm);
fm.call("myFunction","hello");
The call() method is strictly typed - for example if your AS function expects a boolean and you sent it a string, it will not execute. There is also a limit on the possible returned variables - e.g. you cannot send back an Object.
Note that commands sent in the other direction using ActionScript's ExternalInterface.call() method are targeted at document-level by default, not at the 3D API - so if your AS is trying to call something it must exist as a document-level JavaScript function. It is possible to divert this traffic into the 3D API using the FlashEventHandler object, but it gets complicated as your code must implement XML encoding of the traffic - this is done automatically by the document-level script but not by the 3D API.
To answer your second question, in the resources dialog you can define the FlashVars string which is passed to the SWF when it loads - this is the same URL-encoded set of variables that you would send to a SWF when embedding it in an HTML page. It's a static string; you cannot read or edit it with JavaScript but this means it will still work if the user disables the JavaScript engine. -
How can i call a function whose name will be known only at run time
how can i make a call to a function whose name will be known only at run time
Instead, have a function - we should say method -
with a known name, taking a string as argument.Or, specified classes with known names and a no-arg
c'tor that implement a mutual interface, so you can
grab an instance using forName/newInstance, cast the
reference and invoke the interface's doMagic() method.@OP: Best you describe your actual problem, then we could help you with a better solution maybe.
