I have made progress on this small project but still having what I think will be the last issue.
The flex app starts by using HTTPRequest to invoke a php script on the server side. The PHP gathers the name of all of the files in the directory and puts them into an XML file that is passed back to Flex. Flex then loads the XML into a datagrid where the user can select the file they wish to download.
I’m using FileReference to attempt doing the downloads and have incorporated the tutorial example from
http://blog.flexexamples.com/2007/07...ference-class/ into my code.
The incorporated code works and the download is successful when I download the file that the author has in the example. However when I change to load a file from my web site the download starts but soon fails with an error 2038. It seems to me that there is something that prevents the download on my site. Here is the code.
