I want to read from a doc file in my c# code after uploading through FIleuploader control.

if u want to use the MS office 2007 and 2003 formats then u have to use the 3rd party components like txtextcontrol they work in both client side and server side....

  easily bind to database Blob columns and work fine

if u don't want to process the document just want to upload and save it then
