Turning off stupid warnings

[timmay3141]

I'm getting a stupid warning from MSVC++ 6.0. I don't even know what this means:

c:\program files\microsoft visual studio\vc98\include\vector(39) : warning C4786: 'std::reverse_iterator<std::vector<CUSTOMVERTEX,std::allocator<CUSTOMVERTEX> > const *,std::vector<CUSTOMVERTEX,std::allocator<CUSTOMVERTEX> >,std::vector<CUSTOMVERTEX
,std::allocator<CUSTOMVERTEX> > const &,std::vector<CUSTOMVERTEX,std::allocator<CUSTOMVERTEX> > const *,int>' : identifier was truncated to '255' characters in the debug information
c:\program files\microsoft visual studio\vc98\include\vector(39) : while compiling class-template member function '__thiscall std::vector<std::vector<CUSTOMVERTEX,std::allocator<CUSTOMVERTEX> >,std::allocator<std::vector<CUSTOMVERTEX,std::al
locator<CUSTOMVERTEX> > > >::std::vector<std::vector<CUSTOMVERTEX,std::allocator<CUSTOMVERTEX> >,std::allocator<std::vector<CUSTOMVERTEX,std::allocator<CUSTOMVERTEX> > > >(const std::allocator<std::vector<CUSTOMVERTEX,std::allocator<CUSTOMVERTEX> >
> &)'

I guess it's referring to my vector of vectors (it's for a 2D array). The warning doesn't seem to be important or even make any sense, but apparently Microsoft thinks it knows more than me and when I tell it to ignore this warning by adding the line #pragma warning(disable:4786) it gives me the warning anyway. What can I do to fix this?

Try to place the #pragma before any includes.
This warning raised in debug mode only (when debug info generated). It's true: mangled names from templates was truncated...
I think, the best policy is never disable any warnings. One morning (evening, night) this rule may save your life (or career...

Some elaboration: place

#pragma warning(disable:4786)

in StdAfx.h (if you have it) before any includes. In the most outer context, in a word. And don't forget to recompile stdafx.cpp (pre-compiled headers carrier).

Search in help C4786. You will see an option to put in compillers parameters. Put this option and rebuild the project.

I agree with ArkM that you should not disable warnings permanantly... however, you could do it for a specified area. Look in MSDN for #pragma warning(push) and (pop). With this, you can disable it where you want to and have it and vice versa.
