Suppress warning message C4786

Is there any way to suppress warning message C4786 in VC++ 6.0? This is
the message that says "'a very long name generated by a template' :
identifier was truncated to '255' characters in the debug information

I'm using STL and I'm getting hundreds of these, which makes it hard to
find warnings that I probably could (and should) do something about.

I've tried
#pragma warning( disable : 4786 )
and
#pragma warning( disable : C4786 )
and neither has any affect.

#pragma warning( disable : 4786 ) should work fine. Where have you put it?

Search for "STL without warnings" in Google, press "I'm feeling lucky"
you'll find what you need.
You just need Mad Google Skills(tm) :)

If you have an stdafx.h file, try adding the code to disable the warnings
there.

You should avoid putting STL #include's in your header file.

With the #include's in your CPP file, try moving they're location up and
down, but always after the stdafx.h include.

And make sure it's before the "#ifdef _DEBUG"

What the referenced web page
( http://www.codeproject.com/vcpp/stl/stl_without_warnings.asp )
tells me is that I probably can't do it.

Mr Wieland's code contains the following comment:

// BUG: C4786 Warning Is Not Disabled with #pragma Warning
// STATUS: Microsoft has confirmed this to be a bug in the Microsoft
product.
// This warning can be ignored. This occured only in the <map> container.

As it happens, I am using the map container so it looks like I'm out of
luck.

I've found that 4786 can be disabled if you put it in your PCH file at the
top. I think it's not as clear-cut as "it never works".

That does it! Thank you.

Include disable4786.h file described here at the top of your stdafx.h file:

For me, this solution worked everytime. Thanks to Paul Hollingsworth
(the author of this incredible workaround).

Statements dumped into the PCH apply to all your code - even the windows
ones, so dont go putting things like #define new DEBUG_NEW in there, or your
STL code will explode etc.
