Error c4996 Checked Iterators

I use VC++ 2013 and I have a following code:

#pragma warning(disable:4996)

#include <iostream>
#include <fstream>
#include <object.pb.h>

using namespace std;

int main(int argc, char** argv)
Object object;
object.set_name("Ermolaev Ivan");
fstream output("myfile", ios::out | ios::binary);
return 0x0;

But following error continue displayed.

Error 1 error C4996: 'std::_Copy_impl': Function call with parameters that may be unsafe - this call relies on the caller to check that the passed values are correct. To disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how to use Visual C++ 'Checked Iterators' c:\program files (x86)\microsoft visual studio 12.0\vc\include\xutility 2132 1 ProtobufTest


The D prefix is not necessary, it's an indicator for the compiler when you introduce the define on the command line.

You should define this as simply _SCL_SECURE_NO_WARNINGS. It's best to do this in Project Properties -> C++ -> Preprocessor, to have it consistent across all your code.
