How do I enable warning C6244 in MSVC++?

Question

I'd like to enable the warning for "Variable name hiding" as an error in MSVC++, so that things like this will be flagged as an error:

class A
{
    int var ;
    A()
    {
      int var = 5 ; // HIDING: want this to be an error
    }
} ;

To even enable the 6000 series warnings, you have to [perform this procedure](http://stackoverflow.com/a/10163994/111307). — bobobobo, Apr 16 '12 at 03:59

You can use pragma directives:

#pragma warning(error: 6244)

class A
{
    int var ;
    A()
    {
      int var = 5 ; // HIDING: want this to be an error
    }
} ;

@AshBurlaczenko my crystal globe told me to read the title. :) – Luchian Grigore Apr 14 '12 at 19:26
Actually I prefer this way, but unfortunately may have the ["include order" problem](http://stackoverflow.com/questions/7082265/what-is-the-first-line-of-code-that-will-be-compiled). Hence my selection of [the project setting answer](http://stackoverflow.com/a/10157047/111307) as the accepted one – bobobobo Apr 14 '12 at 20:41

So, this doesn't actually work. I still don't know how to [enable](http://stackoverflow.com/questions/4151908/enable-a-single-warning-in-visual-studio) 6000* series warnings – bobobobo Apr 15 '12 at 16:35

Ok, now I know [how to enable the 6000 series warnings](http://stackoverflow.com/a/10163994/111307). – bobobobo Apr 16 '12 at 03:58

there is a treat specific warning as error on the advanced tab of the C++ property pages of your project setting

How would disabling the warning make the compiler treat it as an error? – Luchian Grigore Apr 14 '12 at 20:03
Are you sure? I can't find it. I see the **disable specific warnings** tab, but that's it. – Luchian Grigore Apr 14 '12 at 20:07
I have it as the last option (MSVC c++11 ,but there is one in MSVC 2010 too but maybe it's somewhere else) – engf-010 Apr 14 '12 at 20:10

You can use the /we compiler option to turn a particular error into a warning. For example, /we6244 will make warning C6244 an error. See the documentation for the /w option and its friends for details.
