I finally resorted to native Activex calls as no other way seem to work for me. Personally I wanted to avoid using it. But It works well.

A word of caution here, activeX are not very well supported in browsers other than IE so you need to either have IE Only application or convince the client to upgrade to higher version of asp.net.
