Is there a browser plugin or an extension that allows the user to view .doc files in browser?
I need to embed in my application, a document viewer. So far, I tried using services like google docs, but this solution doesn't work for our application, because of some security problems.
Do you know about the Office Web Apps? Microsoft developed something similar to Google Docs and you can use the Word Web Application to view Word files. It will pretty much display anything - a lot of editing functions from the offline version are not available though.
If you are just looking for a viewer search for "Word ActiveX Viewer" and you will find plenty (commercial) viewers.
