如何删除“ImageList_Read” : 不一致的dll链接警告？
当我构建 Visual C++ 解决方案 (2005) 时，我收到以下警告
1> c:\winddk\7000.0.winmain_win7beta.081212-1400\inc\api\commctrl.h(678) ：参见 'ImageList_Read' 的先前定义
1>e:\xml parse\development\gui\h\wtl4mfc.h(6 ) : 警告 C4273: 'ImageList_Write' : dll 链接不一致
1> c:\winddk\7000.0.winmain_win7beta.081212-1400\inc\api\commctrl.h(679) ：参见 'ImageList_Write'
1>e:\xml parse\development\gui\h\wtl4mfc.h(8 ) : 警告 C4273: 'ImageList_ReadEx' : dll 链接不一致
1> c:\winddk\7000.0.winmain_win7beta.081212-1400\inc\api\commctrl.h(686) ：参见 'ImageList_ReadEx'
1>e:\xml parse\development\gui\h\wtl4mfc.h(9 ) : 警告 C4273: 'ImageList_WriteEx' : dll 链接不一致
1> c:\winddk\7000.0.winmain_win7beta.081212-1400\inc\api\commctrl.h(687) ：参见 'ImageList_WriteEx' 的先前定义
当我检查这两个文件时，我可以看到以下内容：
****在wtl4mfc中.h****
外部“C” { HIMAGELIST WINAPI ImageList_Read(LPSTREAM pstm); BOOL WINAPI ImageList_Write(HIMAGELIST Himl, LPSTREAM pstm);
#if (_WIN32_WINNT >= 0x0501) HRESULT WINAPI ImageList_ReadEx(DWORD dwFlags, LPSTREAM pstm, REFIID riid, PVOID* ppv); HRESULT WINAPI ImageList_WriteEx(HIMAGELIST Himl, DWORD dwFlags, LPSTREAM pstm);
#endif };
在 commctrl.h 文件中，我可以看到以下内容：
WINCOMMCTRLAPI HIMAGELIST WINAPI ImageList_Read(__in struct IStream *pstm); WINCOMMCTRLAPI BOOL WINAPI ImageList_Write(__in HIMAGELIST Himl, __in struct IStream *pstm);
我是 Visual C++ 的初学者，这是来自可供我维护的代码。我怎样才能删除这些警告？如果我构建安装了较低版本 Winddk 的代码，则不会显示这些警告。
是什么导致这些警告？我怎样才能删除它们？
When I build my Visual C++ Solution ( 2005), I get the following warnings
1> c:\winddk\7000.0.winmain_win7beta.081212-1400\inc\api\commctrl.h(678) : see previous definition of 'ImageList_Read'
1>e:\xml parse\development\gui\h\wtl4mfc.h(6) : warning C4273: 'ImageList_Write' : inconsistent dll linkage

When I checked these two files, I can see the following:
****In wtl4mfc.h****
extern "C"
{
HIMAGELIST WINAPI ImageList_Read(LPSTREAM pstm);
BOOL WINAPI ImageList_Write(HIMAGELIST himl, LPSTREAM pstm);
#if (_WIN32_WINNT >= 0x0501)
HRESULT WINAPI ImageList_ReadEx(DWORD dwFlags, LPSTREAM pstm, REFIID riid, PVOID* ppv);
HRESULT WINAPI ImageList_WriteEx(HIMAGELIST himl, DWORD dwFlags, LPSTREAM pstm);
#endif
};
In commctrl.h file I can see the following:
WINCOMMCTRLAPI HIMAGELIST WINAPI ImageList_Read(__in struct IStream *pstm);
WINCOMMCTRLAPI BOOL WINAPI ImageList_Write(__in HIMAGELIST himl, __in struct IStream *pstm);
I am a beginner in Visual C++ and this is from a code which is available for me to maintain. How can I remove these warnings? These warnings are not shown if I build the code where lower version of Winddk is installed.
What is causing these warnings? How can I remove them?

该警告来自两个具有不同 __declspec 的声明。我希望 WINCOMMCTRLAPI 隐藏 __declspec 属性。
要修复它，首先检查您是否需要包含这两个声明 - 也许不同的源文件错误地选择了不同的包含路径？还是直接包含旧版本？其次检查您的构建中是否定义了影响 WINCOMMCTRLAPI 扩展方式的宏。可能是项目设置设置错误。
That warning comes from having two declarations that have different __declspec. I expect WINCOMMCTRLAPI hides a __declspec attribute.
To fix it, first check that you need to get both of those declarations included - perhaps different source files are picking up different include paths erroneously? Or directly including an old version? Second check if there is a macro defined in your build that affects how WINCOMMCTRLAPI is expanded. It may be there is a project setting that has got set wrong.
