Have you tried using `w32-shell-execute'?

(w32-shell-execute "Open" "blabla.chm")

Exactly what I needed, works perfect, thank you.

Sad that these functions are not mentioned in the Emacs manual for
(emacs)Windows Processes.  I'm coding mostly under Linux and the w32-*
functions are not available when trying `describe-function'.

That is because no one has had the time to rewrite that part.

Reading that part I also found that it is about running DOS processes on 
MS Windows. I suggest that we rename to to reflect this.

What version of which manual are you reading?  In the CVS version (and
the one distributed with the pretest), the MS-Windows part _was_
rewritten, and the node's name is "Windows processes".

That's right, but still nowhere mentioned w32-shell-execute.

I'd like to send a patch for this help file with one sentence or so
added.  Admitted in this case it's more intended as practising stunt
for learning more about texinfo and CVS usage.

What I'd like to know is how you guys are handling a changed version
of the Emacs source tree?  If I changed this particular info file I'd
get in trouble when updating the sources.  Am I supposed to merge my
personally changed files every time I'll do an update or is it better
to have a totally independent second Emacs tree for ones pet changes?

I'm eager to learn this.

The CVS version.

I didn't think it was so important at the time I rewrote the Windows
sections of the manual.  I might add it now, but it's still unclear to
me how it would have helped you if it were there.  Did you search the
manual and the doc strings when you were looking for a solution to
your problem, and if you did, what did you search for, i.e. what
search strings and/or regexps did you use for the search?

There's no need, I will add the necessary docs if I understand how it
would have helped you.

CVS will merge files for you automagically.

Then please explain what places did you want to be changed to talk
about Windows as opposed to DOS.  I really think the rewrite you were
asking for was done already, but maybe I missed some places when I did
that.

I had a problem with start-process under Windows so I thought the most
pertinent information would be (emacs)Windows Processes.  I think it
would be helpful to mention that there are a hive of w32-.* helper
functions.  (Which, by the way, are not seen with C-h f under Linux).
There's only mentioned that asynchronous processes should work, mine
did not, so I gave up searching for more information in the manual.

I know 8-), I just wanted to touch my pristine source tree for the
first time and feel the the consequences.

Sounds so easy! I'll give it a try, thanks

I think the original poster has explained now what he missed there. I 
would suggest adding that and pushing much of the current node into a 
subnode about DOS subprocesses. This material might still be valuable, 
but it is not that common to use DOS subprocesses any more I guess.

Thanks again, now I've a conditional:

    (cond
     (ansys-is-unix-system
      (start-process "ansys-help" nil ansys-help))
     ((string= system-type "windows-nt")
      (w32-shell-execute "Open" ansys-help)))

This works fine but when trying to byte-compile I get a warning in the
following manner:

w32-shell-execute is not known to be defined under Linux

Can/should I somehow hide the w32-* stuff when compiling under a Unix
system and how?
