How to: Enable and Disable Code Analysis for C/C++ Warnings

  • Article

To manage warning state, list all code analysis warnings in a separate header file. Include the header file in the source file. Use warning pragma to override the settings in the header file.

To enable or disable a code analysis warning

  1. Create a header file that lists all the code analysis warnings and their initial state, as shown in the following code:

    // WarningState.h
   #pragma warning ( enable : 6001 )
   #pragma warning ( disable : 6011 )
// more warnings here 
// end of file

  2. Include WarningState.h in the application header file. In this case, MyApplication.h represents the header file.

    // MyApplication.h file
   #include "WarningState.h"
// ...
// end of file

  3. Include MyApplication.h file in the source code file. In this case, MyApplication.cpp represents the source file.

    // MyApplication.cpp file
#include "MyApplication.h"

  4. To modify the warning state, use the pragma warning-specifier in a .cpp file, as shown in the following code:

    #pragma warning ( enable : 6011 )
#pragma warning ( disable : 6001 )

Disable All Code Analysis Warnings

Your project may include files, such as third-party source code, for which you do not want to see code analysis warnings. The following code example disables all code analysis warnings for the included third-party files.

#include <codeanalysis\warnings.h>
#pragma warning( push )
#pragma warning ( disable : ALL_CODE_ANALYSIS_WARNINGS )
#include <third-party include files here>
#pragma warning( pop )
