[vtkusers] Display vtk render result in a view of vc

[pagen_ivan at sohu.com]

Hi:
   I want to display the render result in a view inherited from CFormView of VC. The following code is written in a command handling function of MyView.cpp:
   .....
   vtkRenderWindow * Renderwindow=vtkRenderWindow::New();	
   RenderWindow->AddRenderer(Render);
   RenderWindow->SetParentId(m_hWnd); 
   vtkRenderWindowInteractor *iren=vtkRenderWindowInteractor::New();
   iren->SetRenderWindow(RenderWindow); 
   iren->Initialize(); 
		
   RenderWindow->Start();
   iren->Start();
	
   iren->Delete();
   RenderWindow->Delete();
   .....
   
   Till now I'v got the render result in my view, but there remains two problems:
   1. After I terminate the programe, the process of this programe is still running. But if "RenderWindow->SetParentId(m_hWnd);" is removed, it worked properly;
   2. When the programe is running, if I open another data file the render result could be displayed. But then I click the mouse in the render window, the render result of last data file display again;

   Could somebody help me? Thanks!
                                                      ivan
