How to set shortcut for uncomment-region?!?

How to set shortcut for uncomment-region?!?

[Dave Sumsky]

Hi,
I'm using GNU Emacs version 21.2.1 and  I have a problem with  shortcut
for uncomment-region function in c++-mode, in my .emacs file I have:

;; shorcut for comment region
(global-unset-key "\C-c\C-c")
(global-set-key  "\C-c\C-c" 'comment-region)

;; shortcut for uncomment region
(global-unset-key "\C-c\C-u")
(global-set-key "\C-c\C-u" 'uncomment-region)


Now, what is going wrong. Shortcut for comment region is working fine,
but for uncomment region isn't. When I edit a C/C++ source file, I'm in
c++-mode, and then when I try to uncomment a commented region with 
shortcut \C-c\C-u,
I receive this message in echo area: No containing preprocessor conditional

So, could you help me with it? Does anybody know how to do correctly
what I want?
Thanks for any suggestions, Dave

Doesn't M-; do this for you, both commenting and uncommenting?

No, I need to comment, uncomment region

Did you try it on a region?

I thought M-; will comment-region/uncomment-region, as long as there is an
active region?  It does on mine, anyway, and I don't have anything special
set up for this in my .emacs.

Please let me know if this isn't the standard behavior.

That only works when transient-mark-mode is active.  Maybe the OP
doesn't use that.

Hm...  (tries it out).  I see.  I've had that turned on since
like my second day with Emacs.

Hi,
so I would like to begin using M-; for (un)commenting, BUT something is 
still wrong. Transient-mark-mode is active and my .emacs doesn't contain 
anything special. Now, what's the problem:
I have e.g. these lines of source code (c++-mode):

#include <iostream>
#include <fstream>
#include <string>

and I want to comment them all, so I set mark at the beginning of the 
first line with C-<SPC>, I get answer "Mark set", so it's O.K.

C-<SPC>#include <iostream>
               ^
#include <fstream>
#include <string>

I move to the end of the third line

C-<SPC>#include <iostream>
#include <fstream>
#include <string>
                            ^

And now I have a region, which I want to comment, so I try M-;, what's 
the result? This:

#include <iostream>
#include <fstream>
#include <string>                     //

But I would like to see this:

// #include <iostream>
// #include <fstream>
// #include <string>

PLEASE, help me with it, I don't really understand how it is working ...

I have defined these functions as c++-mode hooks:
imenu-add-menubar-index
hs-minor-mode
hl-line-mode
doxymacs-mode
auto-fill-mode
my-c-mode-hook // my c/c++-mode variables customization

Do you think that there could be something intersting with these 
functions featuring default behaviour of M-; ?!?
Thanks, Dave

What happens if you do M-x comment-region ?
