VC++中将外部浏览器控件的句柄转换为IHTMLDocument

之乎者也

得将外部的句柄转成IHTMLDocument才能进行一些COM接口的操作
void CtsDlg::OnGetDocInterface(HWND hWnd)
{
CoInitialize( NULL ); // Explicitly load MSAA so we know if it's installed
HINSTANCE hInst = ::LoadLibrary( _T("OLEACC.DLL") );
if ( hInst != NULL )
{
  if ( hWnd != NULL )
  {
   HWND hWndChild=NULL;
   // Get 1st document window
   //::EnumChildWindows( hWnd, EnumChildProc, (LPARAM)&hWndChild );
   hWndChild=hWnd;
   if ( hWndChild )
   {
    CComPtr<IHTMLDocument2> spDoc;
    LRESULT lRes;
   
    UINT nMsg = ::RegisterWindowMessage( _T("WM_HTML_GETOBJECT") );
    ::SendMessageTimeout( hWndChild, nMsg, 0L, 0L, SMTO_ABORTIFHUNG, 1000, (DWORD*)&lRes );
    LPFNOBJECTFROMLRESULT pfObjectFromLresult = (LPFNOBJECTFROMLRESULT)::GetProcAddress( hInst, ("ObjectFromLresult") );
\\n
    if ( pfObjectFromLresult != NULL )
    {
     HRESULT hr;
     hr = (*pfObjectFromLresult)( lRes, IID_IHTMLDocument, 0, (void**)&spDoc );
     if ( SUCCEEDED(hr) )
     {
      CComPtr<IDispatch> spDisp;
      CComQIPtr<IHTMLWindow2> spWin;
      spDoc->get_Script( &spDisp );
      spWin = spDisp;
      spWin->get_document( &spDoc.p );
      // Change background color to red
      spDoc->put_bgColor( CComVariant("red") );
   IHTMLElement * body=NULL;
   spDoc->get_body(&body);
   if(body)
   {
    BSTR url;
    spDoc->get_URL(&url);
    int sgsdf=0;
   }
     }
    }
   } // else document not ready
  } // else Internet Explorer is not running
  ::FreeLibrary( hInst );
} // else Active Accessibility is not installed
CoUninitialize();
}
