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 Invoke(/* [in] */ DISPID dispIdMember,/* [in] */ REFIID riid,/* [in] */ LCID lcid,/* [in] */ WORD wFlags,/* [out][in] */ DISPPARAMS __RPC_FAR *pDispParams,/* [out] */ VARIANT __RPC_FAR *pVarResult,/*
[out] */ EXCEPINFO __RPC_FAR *pExcepInfo,/* [out] */ UINT __RPC_FAR *puArgErr);

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;}
