正确的方法去拦截OnNewWindow2实现在同一个窗口显示_target的网页

[cpp]  view plain copy

 // CMy5View message handlers
 #include <atlbase.h>
 #include <Mshtml.h>
 #include <COMDEF.H>
 void CMy5View::OnNewWindow2(LPDISPATCH* ppDisp, BOOL* Cancel)
 {
     // TODO: Add your specialized code here and/or call the base class
     CComPtr<IHTMLDocument2> pHTMLDocument2;

     m_pBrowserApp->get_Document((IDispatch **)&pHTMLDocument2);
     if (pHTMLDocument2!=NULL)
     {
         CComPtr<IHTMLElement> pIHTMLElement;
         pHTMLDocument2->get_activeElement(&pIHTMLElement);

         if (pIHTMLElement!=NULL)
         {
             variant_t url;
             HRESULT hr=pIHTMLElement->getAttribute(L"href", 0, &url);
             if (SUCCEEDED(hr))
             {
                 hr=m_pBrowserApp->Navigate2(&url, NULL, NULL, NULL, NULL);

                 url.Clear();

                 if (SUCCEEDED(hr))
                 {
                     *Cancel=TRUE;
                 }
             }
         }
 }
 //  CHtmlView::OnNewWindow2(ppDisp, Cancel);
