A SWF served over http cannot get data from files on the user's file system.
From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of artgrater Sent: Monday, September 01, 2008 11:11 PM To: [email protected] Subject: [flexcoders] Don't need to upload file, but need to display it E4X. I am trying to let the user browse and select a file that I display but not save. For interim test purposes, the HTTPService uploads a file if it's name is already entered in the TextInput control when the btnSelect button is clicked. The XML displays properly in the taStatus TextArea. The problem is that I want to display the XML file that the user browses to, not the file entered in the TextInput. I have tried binding to the 'name' property of FileReference, but that doesn't go to the proper folder. There's no back-end script because I do NOT need to save the selected file to the server. I just need to show it and do some other stuff in another component. Or do I need a back- end script just to tell flex where to locate the file that was browsed to?
