如何在CHtmlView中用OnNewWindow2事件生成自己的浏览器窗口，实现类似于多标签页浏览

方式一

void CCustomHtmlView::OnNewWindow2(LPDISPATCH* ppDisp, BOOL* Cancel) 
{

CWebNavigate *pDlg =  new CWebNavigate;
pDlg->Create(CWebNavigate::IDD,this);
pDlg->OnNewWindow2(pDisp);
      

*Cancel = FALSE;  //如果此处值为TRUE,则无法在新窗口中浏览网页 此处值必须为FLASH
       //CHtmlView::OnNewWindow2(ppDisp, Cancel);
}

.............

void CWebNavigate::OnNewWindow2(LPDISPATCH *ppDisp)

{

        m_wndWeb.SetRegisterAsBrowser(TRUE);      //m_wndWeb 为CHtmlView对象

       *pDisp = m_wndWeb.GetApplication();

}

方式2:

实现DWebBrowserEvents2  

class CIEEvent : public SHDocVw::DWebBrowserEvents2  
{
public:
CIEEvent();
virtual ~CIEEvent();


VOID SetIEhWnd(HWND hWnd){m_hIEWnd = hWnd;}
BOOL Advise(IUnknown *pUnKnown);
VOID UnAdvise();
virtual void BeforeNavigate2(DISPPARAMS __RPC_FAR *pDispParams, VARIANT __RPC_FAR *pVarResult);
virtual ULONG STDMETHODCALLTYPE AddRef() { return 1L; }
virtual ULONG STDMETHODCALLTYPE Release() { return 1L; }
virtual HRESULT STDMETHODCALLTYPE GetTypeInfoCount(UINT __RPC_FAR *pctinfo){return E_NOTIMPL;} 
virtual HRESULT STDMETHODCALLTYPE QueryInterface(/* [in] */ REFIID riid,/* [iid_is][out] */ void __RPC_FAR *__RPC_FAR *ppvObject)
{
if (riid == IID_IUnknown || riid == IID_IDispatch || riid ==DIID_DWebBrowserEvents2)
{
*ppvObject = (void*)this;
return S_OK;
}
return E_NOINTERFACE;
}
virtual HRESULT STDMETHODCALLTYPE GetTypeInfo(/* [in] */ UINT iTInfo,/* [in] */ LCID lcid,/* [out] */ ITypeInfo __RPC_FAR *__RPC_FAR *ppTInfo){return E_NOTIMPL;}

virtual HRESULT STDMETHODCALLTYPE GetIDsOfNames(/* [in] */ REFIID riid,/* [size_is][in] */ LPOLESTR __RPC_FAR *rgszNames,/* [in] */ UINT cNames,/* [in] */ LCID lcid,/* [size_is][out] */ DISPID __RPC_FAR *rgDispId){return E_NOTIMPL;}
