I guess there are two problems :
1. minibuffer is not the same as echo area. Try
M-: M-: (with-current-buffer (window-buffer (minibuffer-window)) (buffer-string))
(i.e. enter a recursive minibuffer) and then you get something.
2. the command loop erases the echo area before running commands, so
whenever you try running your code interactively, it'll report an empty
echo area. Try this instead:
(progn
(message "foo!")
(with-current-buffer " *Echo Area 0*"
(format "Found string: %s" (buffer-string))))
Also, the functions current-message and with-temp-message might be of
interest to you. (But note that current-message also suffers the
problems of being cleared if you call it interactively !)
HTH,
