Flash :: Convert A File To A FileReference Behind The Scenes?
Feb 12, 2012
It would appear that FileReference.upload() is the only way in which you can upload a file to the server in Flash and get feedback about its upload state via a PROGRESS callback. All other methods just go off into the ether and come back when the file upload is completed.
Unfortunately, FileReference appears to insist that a user select the file to be uploaded. There doesn't appear to be a mechanism by which to set the file through code. The reason I need this is that I'm allowing the user to upload massive files and am uploading them in chunks, so, I want to just pack a chunk of data into a FileReference (maybe 5 or 10 megs) and send that off and watch it go. Does anyone have any thoughts on whether it's possible to manually load data into a FileReference object? The data property is read-only, sadly.

I have a working s3 uploader in actionscript that uses the FileReference class so a user can browse for files to upload when he/she clicks on the upload button. I have a web application and I want the user to have his/her configuration saved to s3 as an XML file when they hit the save button, so the "save" button will trigger the upload. However, I cant figure out a way to add the XML file to the FileReference variable I create. I was looking at the File class but that appears to be only usable in AIR. Is it possible to create a FileReference object based off of an XML file that actionscript creates within the application without browsing for a file using FileReference.browse(); ?

I'm building a little recorder in flash and I have a little problem with sending the file that is recorded to php. Is there a way to simply send it with a var of do I need to set it to a file reference, but how can I do that because the only way I see that is that you need to browse or load is from somewhere.

I need to make a flash applet that automatically grabs a specific file on a user's system (iTunes XML file) and auto uploads it to my server. So far I have only been able to accomplish this with a user selecting the file, how to upload a specific file without the user having to go and find it.

I am using the FileReference object. I want to be able to save the local file data into a ByteArray. I know that I can use the data property in Flash 10, but I would like a solution that works for earlier versions of Flash.

I've been trying to build a simple flash uploader to upload files onto a server using the FileReference-class and simple PHP. Trying this on a localhost-server succeeded within two minutes, great!
However, now I am trying to do the same thing on the remote-server, but it keeps giving IO-errors. I have done the following: Put all permissions to 777, in the main folder and also the folder where the pictures are uploaded to Tried different remote servers

The code below compiles fine on the Flex 4 SDK on Fedora 15. Mouse-click opens the dialog box, I click okay, and a file is saved, but the file is empty. I run the same SWF file (that was compiled on the Linux machine) on a Windows machine, and the created file contains the expected data. I was thinking there was a permissions problem, but if that were so, why should Linux even let me save the file? It is going to slow things down immensely if I cannot code something and test it on the same machine...

I'm using Filereference.save() to save a XML file. It's working fine with default filename.But is there a way to force a file extension on the saved file? I'm using "untitled.xml" as the default filename, but if the user changes it to say "myfile", it gets saved as "myfile", rather than "myfile.xml".

limiting or correcting the behaviour of FileReference.save isn't possible.Can anyone suggest an alternative (server is Apache/PHP) that matches all of my criteria from this post and avoids the pitfalls I discussed with Jacob?I'm saving an image from my AS3 app using FileReference.save(). This is the code, which works fine:[code]This opens up the save file dialog as expected. I'm using this rather than sending the byteData to PHP because I want the user to have a familiar dialog box that lets them set their own file name.
The problem comes when users have their operating system configured to display file extensions, like I do. This means that in the save dialog the file name contains the extension as seen in the image below, and so it is very easy for the user to delete that extension when they rename the file. Because the default file type for this box is 'All files', if the extension is deleted the file is saved with no type.I don't know of any way to force a file type on the save dialog (if there is one that would be my preferred route) so failing that can anyone suggest a safe way for me to do this that still allows the user to set the file name themselves using a standard dialog for their OS?I did try putting in a call to FileReference.browse() before the save() as shown in this tutorial, but that throws an error because you can only perform one FileReference call at a time.

how to link the buttons in drop down menu to the content(scenes) within the flash file? The drop down menu has been made using the masks. Those buttons, which are not drop down/masked, work properly. Those which are drop down/masked, do not work. The content appears after clicking on them, then disappears when other (drop down) button is rolled over.

whenever I set my sound to stream and continue to make a movie with multiple scenes. The audio and video get disgustingly out of sync sometimes even off by 30 seconds. I just started an animation its only 10 seconds long with two scenes and the AV is already off by about 5 seconds. Ive worked around this by avoiding scenes altogether but i really don't want to have another 5000 frame scene. I discovered this problem in Flash MX and Im quite annoyed that it still has't been fixed 3 years later!
