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

1. // CMy5View message handlers 
2. #include <atlbase.h> 
3. #include <Mshtml.h> 
4. #include <COMDEF.H> 
5. void CMy5View::OnNewWindow2(LPDISPATCH* ppDisp, BOOL* Cancel)  
6. { 
7.     // TODO: Add your specialized code here and/or call the base class 
8.     CComPtr<IHTMLDocument2> pHTMLDocument2; 
9.      
10.     m_pBrowserApp->get_Document((IDispatch **)&pHTMLDocument2); 
11.     if (pHTMLDocument2!=NULL) 
12.     { 
13.         CComPtr<IHTMLElement> pIHTMLElement; 
14.         pHTMLDocument2->get_activeElement(&pIHTMLElement); 
15.          
16.         if (pIHTMLElement!=NULL) 
17.         { 
18.             variant_t url; 
19.             HRESULT hr=pIHTMLElement->getAttribute(L"href", 0, &url); 
20.             if (SUCCEEDED(hr)) 
21.             { 
22.                 hr=m_pBrowserApp->Navigate2(&url, NULL, NULL, NULL, NULL); 
23.                  
24.                 url.Clear(); 
25.                  
26.                 if (SUCCEEDED(hr)) 
27.                 { 
28.                     *Cancel=TRUE; 
29.                 } 
30.             } 
31.         } 
32. }    
33. //  CHtmlView::OnNewWindow2(ppDisp, Cancel); 
34. }
