Remove secure warnings CRT SECURE NO WARNINGS from projects by default in Visual Studio

Question

Is there a way to set by default for all projects removing the precompiler secure warnings that come up when using functions like scanf    I found that you can do it by adding a line in the project option or a  define  CRT SECURE NO WARNINGS in the beginning of the code   I find myself repeatedly creating new projects for solving programming contests and it is really annoying  and takes valuable time  to add    ifdef  MSC VER  define  CRT SECURE NO WARNINGS  endif   In the beginning of the code  or to set it in the precompiler options every time I start a new project

Not automatically  no  You can create a project template as BlueWandered suggested or create a custom property sheet that you can use for your current and all future projects    Open up the Property Manager  View- Property Manager  In the Property Manager Right click on your project and select  Add New Project Property Sheet  Give it a name and create it in a common directory  The property sheet will be added to all build targets   Right click on the new property sheet and select  Properties   This will open up the properties and allow you to change the settings just like you would if you were editing them for a project  Go into  Common Properties- C C  - Preprocessor  Edit the setting  Preprocessor Definitions  and add  CRT SECURE NO WARNINGS  Save and you re done    Now any time you create a new project  add this property sheet like so      Open up the Property Manager  View- Property Manager  In the Property Manager Right click on your project and select  Add Existing Project Property Sheet    The benefit here is that not only do you get a single place to manage common settings but anytime you change the settings they get propagated to ALL projects that use it  This is handy if you have a lot of settings like  CRT SECURE NO WARNINGS or libraries like Boost that you want to use in your projects

my two cents for VS 2017   I can confirm it works in stdafx h both in these styles   a    pragma once  define  CRT SECURE NO WARNINGS 1   define  WINSOCK DEPRECATED NO WARNINGS 1    b     define  CRT SECURE NO WARNINGS 1   define  WINSOCK DEPRECATED NO WARNINGS 1   pragma once    I have added another define for MSDN network calls    Of course I do prefer a     I can confirm that       define  CRT SECURE NO WARNINGS  without a value  DOES NOT WORK   PS the real point is to put these defines BEFORE declarations of functions  i e  before   h

If your project does not use stdafx h  you can put the following lines as the first lines in your  cpp file and the compiler warning should go away -- at least it did for me in Visual Studio C   2008    ifdef  CRT SECURE NO WARNINGS  undef  CRT SECURE NO WARNINGS  endif  define  CRT SECURE NO WARNINGS 1   It s ok to have comment and blank lines before them

It may have been because I am still new to VS and definitely new to C  but the only thing that allowed me to build was adding   pragma warning disable 4996    At the top of my file  this suppressed the C4996 error I was getting with sprintf  A bit annoying but perfect for my tiny bit of code and by far the easiest   I read about it here  https   msdn microsoft com en-us library 2c8f766e aspx

All the solutions here failed to work on my VS2013  however I put the  define  CRT SECURE NO WARNINGS in the stdafx h just before the  pragma once and all warnings were suppressed  Note  I only code for prototyping purposes to support my research so please make sure you understand the implications of this method when writing your code   Hope this helps
