How to open MS Visio Files in Flex Application

[Ramjane]

We are creating an application in which a user can upload the MS Visio file to the server and then any other user can view it. But we are not sure that user viewing visio files has MS Visio or Visio Viewer Plugin installed. Can we directly open the MS Visio File in the flex application?If No then is there any server side tool which will convert it to PNG or any other image format so that we can view it inside Flex Application?

I doubt there is any chance re. visio.

excel no problem. word, with any modern version, should be okay.

visio...

BEGIN EDIT
.vdx Visio XML Drawing files
.vtx Visio XML Template files
.vsx Visio XML Stencil files

So these formats can be parsed if you can track down a schema. I could not but did not look very hard.

This part was of interest. If it is a user from your business, then you will/should be able to know - and act accordingly. If not, then pretty much figure they do not.

Convert something to .png, and you may as well display it in a browser.
