using DDE from gnu-emacs

using DDE from gnu-emacs

[Ehud Reshef]

Although this looks like a FAQ to me, I could not find it...

I Would like to modify AuCTeX's latex-pdf feature, as to first close
any possibly open instances of the destination PDF file.
I have seen that TeXnicCenter does that using Acrobat Reader's DDE.

I am looking for a way to send to Acrobat, a DDE command from
gnu-Emacs
(not Xemacs).

Did I miss something, or is it supported only from Xemacs ?

TIA
Ehud

Thanks
I'll try to modify that to as per TeXnicCenter (unless there is 
something proven...)

No, no. TeXnicCenter already *does* use DDE - at least in the current
version (and it works like a charm). Read the FAQ (and help pages
pointed to):

Thanks
I Tried to follow the lead from there, and create the following (vey
similar) lisp code:

(defun acrobat-close-doc (file)
  "Close <file> in Acrobat, using DDE."
  (save-excursion
    (set-buffer (get-buffer-create " *ddeclient*"))
    (erase-buffer)
    (insert (concat "[DocClose( " concat(file ".pdf )]" )))
    (call-process-region (point-min) (point-max)
			 "ddeclient" t t nil "acroview" "control")
    (if (= 0 (string-to-int (buffer-string))) t nil)))

(defun TeX-run-pdfLaTeX (name command file)
  "Create a process for NAME using COMMAND to format FILE with
pdfLaTeX."
;  (acrobat-close-all-docs)
  (acrobat-close-doc(file))
  (TeX-run-LaTeX name command file)
  )

(add-to-list 'TeX-command-list
	     (list "PDFLaTeX" "pdflatex\ \\nonstopmode\input %s"
		   'TeX-run-pdfLaTeX nil t))

The problem is that when I run the pdflatex command from auctex, I
get:

acrobat-close-doc: Symbol's function definition is void: file

I'm not very proficient with lisp...

Suggestions?
TIA

You where of course right
Now I will try to change View PDF accordingly ...
