Display a Web Page in a Plain C Win32 Application 是一篇好文章
Transparent Flash Control in Plain C++ 也是一篇好文章
为了把WebBrowser画在窗体上
两个工程对比了下
对比 Flash 的接口 ?
IOleClientSite
IOleInPlaceSiteWindowless
IOleInPlaceFrame
IStorage
IOleClientSite
IOleInPlaceFrame
IDocHostUIHandler
// IOleInPlaceSite
// IOleClientSite
---------------------------------------
So?
IOleInPlaceFrame
IOleClientSite
IDocHostUIHandler
IOleInPlaceSiteWindowless
IOleClientSite
尝试方案
Flash WindowLess 用法
// IOleInPlaceSiteWindowless interface
virtual HRESULT STDMETHODCALLTYPE CanWindowlessActivate(void);
return S_OK;
virtual HRESULT STDMETHODCALLTYPE GetCapture(void);
return S_FALSE;
virtual HRESULT STDMETHODCALLTYPE SetCapture(/* [in] */ BOOL fCapture);
return S_FALSE;
virtual HRESULT STDMETHODCALLTYPE GetFocus(void);
return S_OK;
virtual HRESULT STDMETHODCALLTYPE SetFocus(/* [in] */ BOOL fFocus);
return S_OK;
virtual HRESULT STDMETHODCALLTYPE GetDC(/* [in] */ LPCRECT pRect,
/* [in] */ DWORD grfFlags,
/* [out] */ HDC __RPC_FAR *phDC);
return S_FALSE;
virtual HRESULT STDMETHODCALLTYPE ReleaseDC(/* [in] */ HDC hDC);
return S_FALSE;
virtual HRESULT STDMETHODCALLTYPE InvalidateRect(/* [in] */ LPCRECT pRect,
/* [in] */ BOOL fErase);
virtual HRESULT STDMETHODCALLTYPE InvalidateRgn(/* [in] */ HRGN hRGN,
/* [in] */ BOOL fErase);
return S_OK;
virtual HRESULT STDMETHODCALLTYPE ScrollRect(/* [in] */ INT dx,
/* [in] */ INT dy,
/* [in] */ LPCRECT pRectScroll,
/* [in] */ LPCRECT pRectClip);
NOTIMPLEMENTED
virtual HRESULT STDMETHODCALLTYPE AdjustRect(/* [out][in] */ LPRECT prc);
return S_FALSE;
virtual HRESULT STDMETHODCALLTYPE OnDefWindowMessage(/* [in] */ UINT msg,
/* [in] */ WPARAM wParam,
/* [in] */ LPARAM lParam,
/* [out] */ LRESULT __RPC_FAR *plResult);
return S_FALSE;
如何获取 IID_IViewObjectEx?
只能获取 IID_IViewObject
Q5: 研究 Flash 这两个 Object 如何获得？
IViewObjectEx * m_lpViewObject ;
IViewObjectEx * m_lpViewObjectEx ;
在 Flash 的代码中有以下的特殊处理
hr = m_lpO -> QueryInterface ( IID_IViewObjectEx , ( void **)& m_lpViewObjectEx );
if ( FAILED ( hr ) )
{
m_lpViewObjectEx = NULL ;
hr = m_lpO -> QueryInterface ( IID_IViewObject , ( void **)& m_lpViewObject );
if ( FAILED ( hr ))
return FALSE ;
}
实验后，发现
IOleInPlaceSiteWindowless::InvalidateRect() 根本没有响应到
在 Flash 的基础上修改
