如何在chtmlview 中加入INewWindowManager接口，来监视showmodeldialog弹出的窗口程序?

Question

好像没有这方面的文档，请指教

Answer 1

重载CreateControlSite，返回一个实现了INewWindowManager的对象

Answer 2

.h文件加入如下 代码//INewWindowManagerBEGIN_INTERFACE_PART(HTMLWindow2 , IHTMLWindow2)
INIT_INTERFACE_PART(CDocHostSite,  HTMLWindow2 )
STDMETHOD(showModalDialog)(
LPCWSTR pszUrl,
LPCWSTR pszName,
LPCWSTR pszUrlContext,
LPCWSTR pszFeatures,
BOOL fReplace,
DWORD dwFlags,
DWORD dwUserActionTime);
END_INTERFACE_PART(HTMLWindow2 ).cpp文件加入如下代码
BEGIN_INTERFACE_MAP(CDocHostSite, COleControlSite)
INTERFACE_PART(CDocHostSite, IID_IDocHostShowUI, DocHostShowUI)
INTERFACE_PART(CDocHostSite, IID_IDocHostUIHandler, DocHostUIHandler)
INTERFACE_PART(CDocHostSite, IID_INewWindowManager, NewWindowManager)
#if (_WIN32_IE >= 0x0501) // IE 5.5 and higher
INTERFACE_PART(CDocHostSite, IID_IDocHostUIHandler2, DocHostUIHandler2)
#endif
INTERFACE_PART(CDocHostSite, IID_IInternetSecurityManager, InternetSecurityManager)
INTERFACE_PART(CDocHostSite, IID_IServiceProvider, ServiceProvider)

END_INTERFACE_MAP()
ULONG CDocHostSite::XNewWindowManager::AddRef()
{
METHOD_PROLOGUE(CDocHostSite, NewWindowManager); return pThis->ExternalAddRef();
}ULONG CDocHostSite::XNewWindowManager::Release()
{
METHOD_PROLOGUE(CDocHostSite, NewWindowManager); return pThis->ExternalRelease();
}HRESULT CDocHostSite::XNewWindowManager::QueryInterface(REFIID riid, void ** ppvObj)
{
METHOD_PROLOGUE(CDocHostSite, NewWindowManager); return pThis->ExternalQueryInterface( &riid, ppvObj );
}HRESULT CDocHostSite::XNewWindowManager::EvaluateNewWindow(
LPCWSTR pszUrl,
    LPCWSTR pszName,
    LPCWSTR pszUrlContext,
    LPCWSTR pszFeatures,
    BOOL fReplace,
    DWORD dwFlags,
    DWORD dwUserActionTime
)
{
METHOD_PROLOGUE(CDocHostSite, NewWindowManager);
return pThis->m_pView->OnEvaluateNewWindow(   pszUrl,
      pszName,
      pszUrlContext,
      pszFeatures,
      fReplace,
      dwFlags,
      dwUserActionTime
  );
return E_NOTIMPL;
}但是没有拦截到showmodeldialog()这样的函数，是什么原因呢？

STDMETHODIMP CExtendedHtmlControlSite::XServiceProvider::QueryService(REFGUID guidService,  
REFIID riid,
void** ppvObject)
{
if (riid == IID_INewWindowManager)
{
METHOD_PROLOGUE(CExtendedHtmlControlSite, ServiceProvider);
HRESULT hr = (HRESULT)pThis->ExternalQueryInterface(&riid, ppvObject);
return hr;
}
else
{
*ppvObject = NULL; }
return E_NOINTERFACE;
}
