c++SDK怎么处理IWebBrowser2的新窗口弹出事件

Question

c++SDK怎么处理IWebBrowser2的新窗口弹出事件，请把处理的主要流程和函数说下，谢谢，不用ATL

Answer 1

其实就是IDispatch这个接口的事情。这个接口C++里怎么实现

Answer 2

不是IDispatch,是IConnectionPointContainer，需要捕获的是DWebBrowserEvents2，具体代码参考ATL。

问题是这样的：能到Invoke这个里面，说明监听上了。。可是里面DISPID_NEWWINDOW和DISPID_BEFORENAVIGATE:这个没有触发

/* [local] */ HRESULT STDMETHODCALLTYPE CWBClientSite::Invoke(
    /* [in] */ DISPID dispIdMember,
    /* [in] */ REFIID riid,
    /* [in] */ LCID lcid,
    /* [in] */ WORD wFlags,
    /* [out][in] */ DISPPARAMS *pDispParams,
    /* [out] */ VARIANT *pVarResult,
    /* [out] */ EXCEPINFO *pExcepInfo,
    /* [out] */ UINT *puArgErr)
{
 switch(dispIdMember)
 {
 case DISPID_NEWWINDOW:
  CWebBrowser2_NewWindow2(pDispParams->rgvarg[2].punkVal, &pDispParams->rgvarg[1].pdispVal, pDispParams->rgvarg[0].pboolVal);
  break;
 case DISPID_BEFORENAVIGATE:
  CWebBrowser2_NewWindow2(pDispParams->rgvarg[2].punkVal, &pDispParams->rgvarg[1].pdispVal, pDispParams->rgvarg[0].pboolVal);
  break;
 default:
 break;
 }

 return(S_OK);
}

Answer 4

DISPID_NEWWINDOW

你应该捕获newwindow2或者newwindow3

DISPID_BEFORENAVIGATE

这个应该在挂到新的窗口的BHO里面处理

恩，现在是这么处理的：

case DISPID_NEWWINDOW2:
  CWebBrowser2_NewWindow2(pDispParams->rgvarg[2].punkVal, &pDispParams->rgvarg[1].pdispVal, pDispParams->rgvarg[0].pboolVal);
  break;

可以触发CWebBrowser2_NewWindow2这个函数，但是打开的时候还是在360浏览器上打开的，我想弹出一个新网页是拿我浏览器打开的

void CWBClientSite:: CWebBrowser2_NewWindow2(IUnknown* EventSin, IDispatch** ppDisp, VARIANT_BOOL* pbCancel)
{
 IWebBrowser2 *pBrowserApp;
 HRESULT hr  = -1;
 LPDISPATCH DbgppDisp = NULL;
 IOleObject  *browserObject;
 hr = m_pBrowserObj->QueryInterface(IID_IWebBrowser2, (void**)&pBrowserApp);
 if ( SUCCEEDED(hr) )
 { 
  *pbCancel = VARIANT_FALSE;
  hr = pBrowserApp->get_Application(&DbgppDisp);
  if ( SUCCEEDED(hr) )
  {
   *ppDisp  = DbgppDisp;
  } 
 }

}

Answer 6

不是不是要自己先创建一个窗口，而且里面有webbrowser控件，在获取该控件的IOleObject。。。。

Answer 7

360浏览器改掉了注册表中的CLSID_InternetExplorer了，所以你要用自己的浏览器就要自己开浏览器进程，吧pbCancel设为TRUE.

Answer 8

恩，问题是把pbCancel设为TRUE.后，不会弹出来了。。。点击都没用了

Answer 9

要开新的窗口的话需要创建新的IE实例，直接把旧的传给NewWindow2的ppdosp不会有效果的

那应该怎么办？我现在是直接传过去，，没效果

void CWBClientSite:: CWebBrowser2_NewWindow2( IDispatch* ppDisp, VARIANT_BOOL* pbCancel)
{
 
 MSG    msg;
 LPDISPATCH result = NULL;
 IWebBrowser2 *pBrowserApp;
 IOleObject  *browserObject;
 WNDCLASSEX wc = {0};
 HRESULT hr  = -1;
 LPDISPATCH DbgppDisp = NULL;

 *pbCancel=FALSE;
 
 SendMessageW(
  m_hWindow,
  WM_NEW_IEVIEW,
  (WPARAM)&(msg.hwnd),
  0);
 CWebBrowser *pWebBrowser = (CWebBrowser *)GetWindowLong(m_hWindow, GWL_USERDATA);
 browserObject = pWebBrowser->GetIOleObject();
 //browserObject = *((IOleObject **)GetWindowLong(m_hWindow, GWL_USERDATA));
 hr = browserObject->QueryInterface(IID_IWebBrowser2, (void**)&pBrowserApp);
 if ( SUCCEEDED(hr) )
 { 
  *pbCancel = VARIANT_TRUE;
  pBrowserApp->put_RegisterAsBrowser(*pbCancel);
  hr = pBrowserApp->get_Application(&DbgppDisp);
  
  if ( SUCCEEDED(hr) )
  {
   ppDisp  = DbgppDisp;
  } 
 }

}

帮忙看下这个函数直接调用CWebBrowser2_NewWindow2有没有问题，参数传递是否存在问题
/* [local] */ HRESULT STDMETHODCALLTYPE CWBClientSite::Invoke(
    /* [in] */ DISPID dispIdMember,
    /* [in] */ REFIID riid,
    /* [in] */ LCID lcid,
    /* [in] */ WORD wFlags,
    /* [out][in] */ DISPPARAMS *pDispParams,
    /* [out] */ VARIANT *pVarResult,
    /* [out] */ EXCEPINFO *pExcepInfo,
    /* [out] */ UINT *puArgErr)
{
 switch(dispIdMember)
 {
 case DISPID_NEWWINDOW2:
  CWebBrowser2_NewWindow2( pDispParams->rgvarg[1].pdispVal, pDispParams->rgvarg[0].pboolVal);
  break;
 case DISPID_BEFORENAVIGATE2:
   break;
 default:
 break;
 }

 return(S_OK);
}

Answer 12

你需要自己创建一个新的IE窗口并把结果传递给NewWindow2，参考http://support.microsoft.com/kb/184876

解决了，谢谢。CWebBrowser2_NewWindow2( pDispParams->rgvarg[1].ppdispVal, pDispParams->rgvarg[0].pboolVal);，而且在newwindow里获取到正确的browserObject，就是和创建的时候一样的指针
