Things have changed in Emacs24:

,----
| *** New option `delete-active-region'.
| If non-nil, C-d, [delete], and DEL delete the region if it is active
| and no prefix argument is given.  If set to `kill', these commands
| kill instead.
`----

Before i had to use this:

,----
| (defun tv-delete-char (arg beg end)
|   (interactive "p\nr")
|   (if (region-active-p)
|       (delete-region beg end)
|       (delete-char arg)))
| 
| (global-set-key (kbd "C-d") 'tv-delete-char)
`----
