Q:

How to disable Warnings of Visual Studio 2012?

I have this error:

error C4996: 'fopen': This function or variable may be unsafe. Consider using fopen_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.

and similar errors pop up when I use other old C functions.
My question is: Is there a way that these errors show up like Warnings, without actually preventing the code from compiling ?

A:

You must define _CRT_SECURE_NO_WARNINGS in the preprocessor settings of your project, or #define _CRT_SECURE_NO_WARNINGS at the beginning of your file where you use fopen(). Or just use fopen_s() instead.
