如何在Visual Studio 2010 for C++中正确使用“代码分析”?

问题描述:

如果我安装了Windows 7的全新副本和Visual Studio 2010高级版SP1中,创建一个向导生成的“C++控制台应用程序”,并增加3头到.cpp文件:如何在Visual Studio 2010 for C++中正确使用“代码分析”?

#include <winsock2.h> 
#include <WS2tcpip.h> 
#include <wspiapi.h> 

执行“运行代码分析”会告诉我在微软的源代码警告(项目本身是向导生成的,所以没有错误):

1>c:\program files (x86)\microsoft sdks\windows\v7.0a\include\ws2tcpip.h(729): warning C6386: Buffer overrun: accessing 'argument 1', the writable size is '1*4' bytes, but '4294967272' bytes might be written: Lines: 703, 704, 705, 707, 713, 714, 715, 720, 721, 722, 724, 727, 728, 729

这使得代码分析不能用于大项目 - 我得到成千上万的警告在微软的头文件,我不能找到我自己的警告之间:(是否有任何方式排除微软的头s/SDK从代码分析,所以它会变得可用?

P.S.我知道C++不是Visual Studio的良好支持语言,但由于现有项目需要支持和改进,因此我无法更改语言:(。

您可以禁用代码分析警告, “T的PREfast清洁与warning()#pragma:??

#include <codeanalysis\warnings.h> 
#pragma warning(push) 
#pragma warning (disable: ALL_CODE_ANALYSIS_WARNINGS) 

// include headers 

#pragma warning(pop)

谢谢,这彻底解决了我的问题^ _^ – grigoryvp 2011-03-16 13:23:28

+0

这非常有用。谢谢。我得到了一个来自windows功能的警告,这是不正确的。警告说我不能指定0作为#3参数,但在msdn中我说可以这样做。 – James 2016-04-03 13:12:39

您是否尝试过使用CAExcludePath环境变量除去那些包含系统头文件目录

CAExcludePath='C:\Program Files (x86)\Windows Kits\10\Include\10.0.10586.0\ucrt;c:\program files (x86)\microsoft visual studio 14.0\vc\include;c:\program files (x86)\windows kits\8.1\include\um;c:\program files (x86)\microsoft visual studio 14.0\vc\include\sys;'
