Sort of a limitation in flex, but created because of browser security. So its not really a limitation of flex, but a limitation of the web in general.
What you are trying to do is very easy, though, so I wouldn't worry. If you must send the file back and forth, you always can. In fact, its so simple I've made you an example (click the link to see it in action): http://groupnetwork.com/tools/echoDownload.php?filename=test.txt <http://groupnetwork.com/tools/echoDownload.php?filename=test.txt&filedata=t his%20is%20what%20goes%20in%20the%20txt%20file> &filedata=this is what goes in the txt file <? if($_REQUEST['filename']=="" || $_REQUEST['filedata']=="") exit(); //no filename or data specified header("Content-Disposition: inline; filename=\"".$_REQUEST['filename']."\""); header("Content-Type: application/octet-stream"); header("Content-Type: application/force-download"); header("Content-Type: application/download"); header("Content-Transfer-Encoding: binary"); header("Content-Length: ".( strlen( $_REQUEST['filedata'] ) + 1 ) ); header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); echo $_REQUEST['filedata']; exit(); ?> From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of coder3 Sent: Thursday, January 31, 2008 6:39 PM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] how to create a file and then download so basically i have to generate the file on server? currently my server returns an xml file via httpService. but i need a text file for user to download. The best way is to create that (temp) text file on my application and then download it. but sounds like it can't be done and i have to call my server with the extra filtering parameters to make it generate the text file. isn't this one of the Flex limitations? -c Seth Caldwell-2 wrote: > > You shouldn't have to save it on the server at all.
