emacsclient and gnuclient on msw2000

["B. T. Raven" <nihil@nihilo.net>]

I want to associate certain file extensions with Emacs so that a new 
instance of Emacs is not opened when a file is clicked on. Is it 
possible to do this in a w32 environment? Recently I saw this in the ng 
but I don't understand it:

"
REM $Id: emacsassoc.bat,v 1.1 2003/01/10 08:21:27 reichr Exp $
REM You should adjust the path to gnuclientw.exe
REM %%1 is needed for 4nt, %1 can be used for cmd.exe

ftype emacs-file=c:\emacs\bin\gnuclientw.exe -q -F "%%1"
assoc .vhdl=emacs-file
assoc .vhd=emacs-file
assoc .v=emacs-file
assoc .c=emacs-file
assoc .txt=emacs-file
assoc .el=emacs-file
assoc .tex=emacs-file
"

I have changed the path to match my local one but I see that in the bin 
directory I have emacsclientw and not gnuclient.

I have deleted the .txt association (with Notepad) from the w2000 
extensions and I wanted to do something like in the above example to 
have any .txt file opened in a buffer in an already open emacs instance.
Is that possible?

My version is 22.1

Thanks,
Ed
