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

// 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); 
}
