I'm trying to upgrade a little web application that hosts word and excel files and lets users download them.
What I would like to do is give the user the ability to download the file edit it and re-upload the file. While this is really easy to do I'm wondering if I can automate the process.
So what I'm trying to do is download the file onto the users PC, open it have the user edit the document and once closed (write lock removed) re-upload the file back to my web app.
I've been reading up on using isolated storage which seems to mean that I can download a file to the users machine, but unfortunately not execute it to open it.
Does anyone have any suggestions how I can open word file from my website and allow the user to save it so I can re-upload it. I know share point kinda does this, but trying to do it using PHP. I cant use webdav either, hence the idea of using silver light.
