完了完了，情况危急的时刻，居然脑子空了，问大家一个问题。。
这个类是这样的：

class CIOleUILinkContainer : public IOleUILinkContainer
    {
    private:
        ULONG                   m_cRef;
        LPCPage                 m_pPage;
        UINT                    m_iTenant;
        LPOLEUILINKCONTAINER    m_pDelIUILinks;

    public:
        BOOL                    m_fDirty;   //No reason to hide it.

    protected:
        STDMETHODIMP GetObjectInterface(DWORD, REFIID, LPLPVOID);

    public:
        CIOleUILinkContainer(LPCPage);
        ~CIOleUILinkContainer(void);

        BOOL FInit(void);
        BOOL IsDirty(void);

        STDMETHODIMP         QueryInterface(REFIID, LPLPVOID);
        STDMETHODIMP_(ULONG) AddRef(void);
        STDMETHODIMP_(ULONG) Release(void);

        STDMETHODIMP_(DWORD) GetNextLink(DWORD);
        STDMETHODIMP         SetLinkUpdateOptions(DWORD, DWORD);
        STDMETHODIMP         GetLinkUpdateOptions(DWORD, LPDWORD);
        STDMETHODIMP         SetLinkSource(DWORD, LPSTR, ULONG
                                 , ULONG FAR *, BOOL);
        STDMETHODIMP         GetLinkSource(DWORD, LPSTR FAR *
                                 , ULONG FAR *, LPSTR FAR *
                                 , LPSTR FAR *, BOOL FAR *
                                 , BOOL FAR *);
        STDMETHODIMP         OpenLinkSource(DWORD);
        STDMETHODIMP         UpdateLink(DWORD, BOOL, BOOL); 
 
        STDMETHODIMP         CancelLink(DWORD);
    };

typedef CPage *LPCPage;

我在另外一个类里面调用：

BOOL CPages::FGetUILinkContainer(LPCIOleUILinkContainer *ppObj)
    {
    LPCIOleUILinkContainer  pObj;

    *ppObj=NULL;

    if (NULL==m_pPageCur)
        return FALSE;

    pObj=new CIOleUILinkContainer(m_pPageCur);

    if (NULL==pObj)
        return FALSE;

    if (!pObj->FInit())
        {
        delete pObj;
        return FALSE;
        }

    pObj->AddRef();
    *ppObj=pObj;
    return TRUE;
    }

就这一句：
pObj=new CIOleUILinkContainer(m_pPageCur);

居然给我报了下面的错：
1>PAGES.obj : error LNK2019: 无法解析的外部符号 "public: __thiscall CIOleUILinkContainer::CIOleUILinkContainer(class CPage *)" (??0CIOleUILinkContainer@@QAE@PAVCPage@@@Z)，该符号在函数 "public: int __thiscall CPages::FGetUILinkContainer(class CIOleUILinkContainer * *)" (?FGetUILinkContainer@CPages@@QAEHPAPAVCIOleUILinkContainer@@@Z) 中被引用

lz不行了，求大家帮助。。

坑爹啊 大家都下班了么？

目测是类的构造函数只有定义没有实现 ATL+G一下看看？有装番茄没？
