項目從VS2008升級到VS2010的過程中, 碰到挺多問題,
1. C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\atlmfc\include\atlcore.h(35): fatal error C1189: #error :  This file requires _WIN32_WINNT to be #defined at least to 0x0403. Value 0x0501 or higher is recommended.

Causes in staafx.h:
#ifndef _WIN32_WINNT        // Allow use of features specific to Windows XP or later.                  
#define _WIN32_WINNT 0x0401    // Change this to the appropriate value to target other versions of Windows.
#endif                       

Fix:
#ifndef _WIN32_WINNT        // Allow use of features specific to Windows XP or later.                  
#define _WIN32_WINNT 0x0501    // Change this to the appropriate value to target other versions of Windows.
#endif 

2. acrxEntryPoint.cpp
    v:\acade\acepageman\AcePrmNavManager.h(88): error C2011: '__EventingCriticalSectionStub' : 'struct' type redefinition
          v:\acade\acepageman\AcePrmNavManager.h(88) : see declaration of '__EventingCriticalSectionStub'
    v:\acade\acepageman\AcePrmNavManager.h(88): error C2953: '__eventingGetAddr' : class template has already been defined
          v:\acade\acepageman\AcePrmNavManager.h(88) : see declaration of '__eventingGetAddr'
    v:\acade\acepageman\AcePrmNavManager.h(88): error C2011: '__eventNode' : 'struct' type redefinition
          v:\acade\acepageman\AcePrmNavManager.h(88) : see declaration of '__eventNode'
    v:\acade\acepageman\AcePrmNavManager.h(88): error C2011: '__eventMainNode' : 'struct' type redefinition
          v:\acade\acepageman\AcePrmNavManager.h(88) : see declaration of '__eventMainNode'
    v:\acade\acepageman\AcePrmNavManager.h(88): error C2079: 'AcePrmInputContextReactor::__EventingCS' uses undefined struct '__EventingCriticalSectionStub'

這個是因為升級到2010, 導(dǎo)致的頭文件 <atlevent.h>不能正確的被引用. 在VS2008 中, 用到__event的時候不需要收到引用此頭文件, 但是在2010中一定要明確引用, 否則就會出現(xiàn)上面的錯誤.
