I'm using Flex in Flash Player 10 on Windows, using FileReference to load a file into memory, as below. My issue is that when a file is locked by Windows, my FileReference is not giving me any feedback that the file is inaccessible--it simply never dispatches any events after my calling load(). Does anyone have insight into how to tell...

Hello, I am trying to call the browse() method of the FileReference class from JavaScript (a user clicks on a text that uses the ExternalInterface to call a method in Flash).

Let's say a user is starting to upload a file to the server via FileReference. What happens to that temporary file if the user cancels the upload or closes the browser? At what point is the server script called? Is the server script (in my case, ColdFusion) called only once the file has been successfully put on the server? I'm trying to...

I am trying to allow download of a particular file that the user has generated (or will generate). If they try to download the file AFTER generating, the fileReference does not seem to create the new object (it downloads the old file). Code is something like this: private function downloadFile():void { var node:XML = XML(myTree.se...
Hello, I would like to store a FileReference object somehow and load it when the SWF loads again. I tried to use the SharedObject class but it does not seem to work. I suspect that what I want to do is not doable due to security issues (not using Adobe AIR), but I wanted to check. Does anyone please know if there is anyway to store a ...
Hi all, I need to upload a very large file to my server, through my Flex application, and I see that Flex Filereference upload() seems to be able to handle it. Does the upload() methods uploads a 'stream' to the servlet, or does it sends the whole ByteArray (As I understand it, the ByteArray will have the whole file contents, so a >1Gb...

I am able to create File objects but I won...
I need to call FileReference.save() after a web service call has completed, but this method has a restriction: "In Flash Player, you can only call this method successfully in response to a user event (for example, in an event handler for a mouse click or keypress event). Otherwise, calling this method results in Flash Player throwing an ...
Can I develop a Flash AS3 download swf that will let a user select a location on their hard drive to download files to and then start the download of multiple files (in the same way I can do with upload)? Or should I zip all the multiple files first and download zipped files to local disk. My users will want to download potentially hun...
