Add the following to .emacs
(provide 'hippie-exp)

And the customize the variable hippie-expand-try-functions-list like
for example
(setq hippie-expand-try-functions-list
      '(try-expand-dabbrev-visible  ;from visible parts of all windows
        try-expand-dabbrev          ;from current buffer
        try-expand-dabbrev-all-buffers  ;from all other buffers
        try-expand-tag                  ;Note: Expand from "TAGS"
table.
      )

Then finally do
M-x hippie-expand
