由于更新了库，我必须将大型 c++ 程序从 VS2010 迁移到 VS2015。在VS2010中全部编译OK。VS2015的编译器现在在微软自己的atlcom.h中显示错误

我没有机会放弃 ATL 的东西，因为我的 DLL 是依赖于 ATL 的主要程序的扩展（并且在 VS2015 中编译......）。

这是 cl 2015 的错误消息：

错误指向atlcom.h（VS2015的编译器）的第3448行：

CComContainedObject<contained> m_contained;

CComContainedObject 的定义是 atlcom.h 的第 3277 行：

template <class Base> //Base must be derived from CComObjectRoot
class CComContainedObject : public Base
{
public:
    typedef Base _BaseClass;
    CComContainedObject(_In_opt_ void* pv) 
    {
        m_pOuterUnknown = (IUnknown*)pv;
    }
    // some additional members
}

我的课是：

class ATL_NO_VTABLE CMyReferenceData :

        public CQcEdoBase,
        public IQcEdoReferenceData,
        public IPersistStream,
        public IZEDORenderCallback,
        public IZEDOInteractionCallback,
        public IZEDOSelectionCallback,
        public CComCoClass<CMyReferenceData, &CLSID_CMyReferenceData>
{
    UniqueIDType id;
    QMutex PopupMenuMutex;
    static bool DrawHUDElements;
    static QHash<UniqueIDType, UniqueIDType> loadedElementIdDict;

public:
    CMyReferenceData();

    DECLARE_REGISTRY_RESOURCEID(IDR_QCEDOREFERENCEDATA)
    DECLARE_PROTECT_FINAL_CONSTRUCT()

    BEGIN_COM_MAP(CMyReferenceData)
    COM_INTERFACE_ENTRY(IQcEdoReferenceData)
    COM_INTERFACE_ENTRY_CHAIN(CQcEdoBase)
    COM_INTERFACE_ENTRY(IPersistStream)
    COM_INTERFACE_ENTRY(IZEDOInteractionCallback)
    COM_INTERFACE_ENTRY(IZEDORenderCallback)
    COM_INTERFACE_ENTRY(IZEDOSelectionCallback)
    END_COM_MAP();

    // IEDOText
    STDMETHOD(get_ID)(/*[out, retval]*/ unsigned long long *pVal);
    STDMETHOD(put_ID)(/*[in]*/ unsigned long long newVal);

    // IZEDOInteractionCallback
    STDMETHOD(OnMenuCommand)(IZElement * piElement, long Id);
    STDMETHOD(OnPopupMenu)(IZElement * piElement, LONG_PTR HWND, LONG clientX, LONG clientY, eZSubSelectionType SelectionType, IZMenu* piMenu, VARIANT_BOOL * bOverride);

    // IPersistStream
    STDMETHOD(GetClassID) ( LPCLSID lpClassID) ;
    STDMETHOD(IsDirty)( void);
    STDMETHOD(Load)(IStream *pStm);
    STDMETHOD(Save)(IStream *pStm, BOOL fClearDirty);
    STDMETHOD(GetSizeMax)(ULARGE_INTEGER *pcbSize);

    // IZEDORenderCallback
    STDMETHOD(OnDraw)(IZElement * piElement, IZRender * piRender, VARIANT_BOOL * bOverride);
    STDMETHOD(OnHotDraw)(IZElement * piElement, IZRender * piRender, VARIANT_BOOL * bOverride);
    STDMETHOD(OnDrawAccessories)(IZElement * piElement, IZRender * piRender, VARIANT_BOOL * bOverride);

    // IZEDOSelectionCallback
    STDMETHOD(OnDeselect)(IZElement* piElement, VARIANT_BOOL* pOverride);
    STDMETHOD(OnSelect)(IZElement* piElement, VARIANT_BOOL* pOverride);

    // Standard c++
    static bool DisplayHUD();
    static bool ToggleDisplayHUD();
    static void SetDisplayHUDEnabled(bool yes);

    static void ClearElementIdDict();
};

有任何想法吗？你真的很受欢迎。
