Change startup dictonary for ispell?

[Paminu]

I use emacs as my editor. I would like it to always use danish dictionary so
I have tried the following in my .emacs file:

;; Flyspell Mode
(setq-default aspell-program-name "ispell")
(setq ispell-dictionary "dansk")
(add-hook 'text-mode-hook 'flyspell-mode)

I have also tried:

;; Flyspell Mode
(setq-default aspell-program-name "aspell")
(setq ispell-dictionary "dansk")
(add-hook 'text-mode-hook 'flyspell-mode)

but nothing helps I still have to manually change the dictionary to danish
in emacs.

Hope someone can help!
