did you find a way to solve your problem? I'm looking into just opening the file to view allow users to view it but I haven't come across anything yet.
No. Still can't open/view file on remote machines. Even simplest file, no Js or special coding is not viewable. Very Frustrating.
How do you save your Excel files? CVS, XLS?
You can save files in XLS and open it with Excel in AIR2:
There is also a nice AS3XLS library used there allowing to read and write XLS files:
Hope that helps.
