UVC扩展单元和Directshow集成

我试图修改MSDN link中提供的UVC扩展单元代码。我已经向XUProxy.cpp中提供的CExtension类添加了其他方法。所有这些方法都添加到interface.idl文件中。UVC扩展单元和Directshow集成

这是代码片段。如在http://msdn.microsoft.com/en-us/library/windows/desktop/dd377566%28v=vs.85%29.aspx提供

STDMETHODIMP CExtension::GetAllCapDevices(
     PDEVICELIST pList, 
     ULONG *pulDevCount, 
     ULONG ulListNum) 
{ 
    HRESULT hr = S_OK; 
    IEnumMoniker *pEnum; 

    CoInitializeEx(NULL, COINIT_MULTITHREADED); 

    hr = EnumerateDevices(CLSID_VideoInputDeviceCategory, &pEnum); 
    if (SUCCEEDED(hr)) 
    { 
     DisplayDeviceInformation(pEnum); 
     pEnum->Release(); 
    } 

    return hr; 
}

EnumerateDevices和DisplayDeviceInformation是一样的。

我已经将streams.h，strmbase.lib和strmiids.lib添加到源文件中，如下所示。

TARGETLIBS= \ 
     $(SDK_LIB_PATH)\kernel32.lib   \ 
     $(SDK_LIB_PATH)\user32.lib    \ 
     $(SDK_LIB_PATH)\gdi32.lib    \ 
     $(SDK_LIB_PATH)\advapi32.lib   \ 
     $(SDK_LIB_PATH)\comdlg32.lib   \ 
     $(SDK_LIB_PATH)\ole32.lib    \ 
     $(SDK_LIB_PATH)\oleaut32.lib   \ 
     $(SDK_LIB_PATH)\uuid.lib    \ 
     $(SDK_LIB_PATH)\comctl32.lib   \ 
     $(SDK_LIB_PATH)\i386\stream.lib   \ 
     $(SDK_LIB_PATH)\i386\strmbase.lib  \ 
     $(SDK_LIB_PATH)\i386\strmiids.lib  \ 
     $(SDK_LIB_PATH)\i386\strsafe.lib 

INCLUDES=\ 
    C:\Program Files\Microsoft SDKs\Windows\v6.1\Include\

在建设这个源文件我收到以下错误（从了生成日志文件的部分细节）

难道我犯错源文件的语法？我已将Platform SDK的路径包含在SOURCE文件的INCLUDES字段中。我错过了其他的东西吗？

在此先感谢。

我已经解决了我的问题，通过重新排列头文件中包含的头文件的顺序和我的项目的源文件cpp 。

看一看下面的链接 C/C++ include file order/best practices

而且我做了UVC扩展单元的工作完美:-)

谢谢堆栈溢出家伙。
