How to: Enable and Disable Code Analysis for C/C++ Warnings
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
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
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
Include MyApplication.h file in the source code file. In this case, MyApplication.cpp represents the source file.
// MyApplication.cpp file #include "MyApplication.h"
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 )
