先說實在的：最終解決辦法是實現IDocHostUIHandler接口，在GetHostInfo方法里解決，但“實現接口”意味著QueryInterface、AddRef、Release三個方法必須實現，所以相關代碼是：
class CMyWebBrowser : public IDocHostUIHandler
{
public:
    CMyWebBrowser() { m_cRef = 0; }
    virtual ~CMyWebBrowser() {}

    LONG                m_cRef;

private:
    HRESULT STDMETHODCALLTYPE QueryInterface(REFIID riid, void **ppvObject)
    {
        HRESULT result = S_OK;

        if (IsBadWritePtr(ppvObject, sizeof(LPVOID))) 
            result = E_INVALIDARG;  

        if (result == S_OK)
        {
            *ppvObject = NULL; 

            if ( IsEqualIID( riid, IID_IUnknown ) )
                *ppvObject = this;
            //             else if ( IsEqualIID( riid, IID_IOleClientSite ) )
            //                 *ppvObject = (IOleClientSite *) this;
            else if ( IsEqualIID( riid, IID_IDocHostUIHandler ) )
                *ppvObject = (IDocHostUIHandler *) this;
            else
                result = E_NOINTERFACE;
        }

        if (result == S_OK)
            this->AddRef(); 

        return result; 
    }

    ULONG STDMETHODCALLTYPE AddRef(){
        InterlockedIncrement(&m_cRef); 
        return m_cRef;
    }

    ULONG STDMETHODCALLTYPE Release() {
        ULONG ulRefCount = InterlockedDecrement(&m_cRef);

        return ulRefCount; 
    }

    HRESULT STDMETHODCALLTYPE EnableModeless(BOOL fEnable) { return S_OK; }

    HRESULT STDMETHODCALLTYPE FilterDataObject(IDataObject *pDO,IDataObject **ppDORet){return S_OK;}

    HRESULT STDMETHODCALLTYPE GetDropTarget(IDropTarget *pDropTarget, IDropTarget **ppDropTarget){return S_OK;}

    HRESULT STDMETHODCALLTYPE GetExternal(IDispatch **ppDispatch){return S_OK;}

    HRESULT STDMETHODCALLTYPE GetOptionKeyPath(LPOLESTR *pchKey,DWORD dw){return S_OK;}

    STDMETHOD(GetHostInfo)(DOCHOSTUIINFO *pInfo) {
        pInfo->cbSize = sizeof(DOCHOSTUIINFO);
        pInfo->dwFlags |= DOCHOSTUIFLAG_NO3DBORDER;
        pInfo->dwDoubleClick = DOCHOSTUIDBLCLK_DEFAULT;
        pInfo->pchHostCss = 0;
        pInfo->pchHostNS = 0;

        return S_OK;
    }

    HRESULT STDMETHODCALLTYPE HideUI(VOID){return S_OK;}

    HRESULT STDMETHODCALLTYPE OnDocWindowActivate(BOOL fActivate){return S_OK;}

    HRESULT STDMETHODCALLTYPE OnFrameWindowActivate(BOOL fActivate){return S_OK;}

    HRESULT STDMETHODCALLTYPE ResizeBorder(LPCRECT prcBorder,IOleInPlaceUIWindow *pUIWindow,BOOL fFrameWindow){return S_OK;}

    HRESULT STDMETHODCALLTYPE ShowContextMenu(DWORD dwID, POINT *ppt, IUnknown *pcmdtReserved,IDispatch *pdispReserved){return S_OK;}

    HRESULT STDMETHODCALLTYPE ShowUI(DWORD dwID,
        IOleInPlaceActiveObject *pActiveObject,
        IOleCommandTarget *pCommandTarget,
        IOleInPlaceFrame *pFrame,
        IOleInPlaceUIWindow *pDoc
        ){return S_OK;}

    HRESULT STDMETHODCALLTYPE TranslateAccelerator(LPMSG lpMsg,
        const GUID *pguidCmdGroup,
        DWORD nCmdID
        )
    {return S_OK;}

    HRESULT STDMETHODCALLTYPE TranslateUrl(DWORD dwTranslate,
        OLECHAR *pchURLIn,
        OLECHAR **ppchURLOut
        )
    {return S_OK;}

    HRESULT STDMETHODCALLTYPE UpdateUI(VOID) {return S_OK;}
};

1.要寫的更通用一點，就是上述類就這么些內容，然后WEBBrowser從這個類繼承。

2.除了實現這個接口外，別忘了SetUIHandler，這個不難查到，這里就不寫了。

 

牢騷一下：項目中用到WEBBrowser，由于項目組中只有我一個人做過WEB，所以這玩意一直是我維護，最近由于我給里面的Html加了DocType，導致WEBBrowser出現了3D邊框，不管是css的border:0還是body的leftmargin和topmargin，都不管用，查了很多資料（主要是google外國人的），都說實現IDocHostUIHandler接口，在GetHostInfo方法里能干掉3D邊框，但我按照網上做的，結果要么報錯，要么GetHostInfo不走，郁悶了我，折騰了兩天，最后幾乎不懂COM的我還是覺得QueryInterface等3個方法要實現，結果去查，果然如此，實現之后，搞定~~~
