Code looks good. Do you have the same version of office installed? Is it Office 2007 installed in your machine?

i removed worddoc.active() function from code bcoz it was showing error in server. so now after publishing i am getting new error.... error is:---

System.Runtime.InteropServices.COMException: Word has encountered a problem.

Hey..Is it the same old problem with Word Templates being corrupted. Open word manually and see.. if it crashes or not. If it is the same problem, then you need to get Normal.dot file and replace it with your one. :doh:
