how do i keep emacs server running when the current window is closed (x) on windows using emacsW32?

Question

I'm using EmacsW32 (patched) on windows. Emacs is running in server mode so that subsequent calls to emacsclientw open files in the same server session.

I have C-x C-c mapped to make the current frame invisible and not kill the emacs server process. I'd like clicking the window's X (close) button to also just hide the frame & not terminate the server process as it currently does.

Any ideas ? Thanks!

May I ask how you "make the current frame invisible and not kill the emacs server process"? – Scut

Never mind, I found it... for reference, this works perfectly: emacs-fu.blogspot.com/2009/03/windows-and-daemons.html – Scut

Sure, I have a method of doing this. There may be refinements possible, but this is a good starting place.

First, I setup a variable and advise the kill-emacs function

(defvar bnb/really-kill-emacs nil)
(defadvice kill-emacs (around bnb/really-exit activate)
    "Only kill emacs if the variable is true"
    (if bnb/really-kill-emacs
        ad-do-it)
      (bnb/exit))

The bnb/exit function just makes the frame invisible like what you have bound to C-x C-c.

I then have an additional function to properly exit emacs if that is ever necessary. That will set the variable and call kill-emacs as follows.

(defun bnb/really-kill-emacs ()
    (interactive)
    (setq bnb/really-kill-emacs t)
    (kill-emacs))

Thanks! Most of the time I'll be using C-x C-c, but found myself X'ing out the window recently & the server restarts were driving me crazy :-) – Sewing

+1 Thanks for the tip... but would you mind providing the bnb/exit function, too? I put this code in my init.el, and now I can't exit without calling bnb/really-kill-emacs because it says "Symbol's function definition is void: bnb/exit". Sorry, I'm new to emacs and couldn't figure out how to write the function in question. – Scut
