关于xmllite的问题，恳请高手解答一下！

[walk3976]

我在一个DLL中调用了xmllite，编译的时候会报xmllite.h文件错误如下：

error C2146: syntax error : missing ';' before identifier 'IXmlReader'
 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
 error C2146: syntax error : missing ';' before identifier 'IXmlReader'

 error C2061: syntax error : identifier 'IXmlReader'
 error C2061: syntax error : identifier 'IXmlReader'
: error C2061: syntax error : identifier 'IXmlReader'

而我在普通的win32控制台程序中可以正常加载xmllite.lib xmllite.h等
是不是xmllite不支持DLL啊
看了半天 xmllite.h头上写了写编译配置的东西，也不知道是不是跟这个有关，请高手解答一下，多谢

缺少了IXmlReade等的定义吧。
error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

这个应该是你的代码是V6.0的移植到高板本的VS上去了，把没有定义函数类型的地方定义为void

[walk3976]

#if defined(__cplusplus) && !defined(CINTERFACE)
    
    MIDL_INTERFACE("7279FC81-709D-4095-B63D-69FE4B0D9030")
    IXmlReader : public IUnknown
    {
    public:
        virtual HRESULT STDMETHODCALLTYPE SetInput( 
            /*  */ 
            __in_opt  IUnknown *pInput) = 0;
        
        virtual HRESULT STDMETHODCALLTYPE GetProperty( 
            /*  */ 
            __in  UINT nProperty,
            /*  */ 
            __out  LONG_PTR *ppValue) = 0;
        
        virtual HRESULT STDMETHODCALLTYPE SetProperty( 
            /*  */ 
            __in  UINT nProperty,
            /*  */ 
            __in_opt  LONG_PTR pValue) = 0;
        
        virtual HRESULT STDMETHODCALLTYPE Read( 
            /*  */ 
            __out_opt  XmlNodeType *pNodeType) = 0;
        
        virtual HRESULT STDMETHODCALLTYPE GetNodeType( 
            /*  */ 
            __out  XmlNodeType *pNodeType) = 0;

这些都是定义过的，而且我是在VS2005下调用的，在写win32控制台的时候可以成功调用，但是在DLL工程里面调用的话就会出现上面的问题，不知道是不是不支持二次封装

error C2086: 'int IXmlReader' : redefinition
检查一下哪里有重复定义的地方

或者xmllite的头文件里面放了一些实现的东东，然后你的编译选项，有跟调用的lib不一致

[sssnowman]

这个头文件怎么是MIDL编译器产生的，xmllite是个COM组件形式提供的吗？不好意思，我没用过这个东西
