HWND hWnd = (HWND)cvGetWindowHandle("Original Image");
HWND hParent = ::GetParent(hWnd);
::SetParent(hWnd,GetDlgItem(IDC_1)->m_hWnd);
::ShowWindow(hParent,SW_HIDE);

cvvNamedWindow( "Image Processing", 0);
HWND hWnd2 = (HWND)cvGetWindowHandle("Image Processing");
HWND hParent2 = ::GetParent(hWnd2);
::SetParent(hWnd2,GetDlgItem(IDC_2)->m_hWnd);

you can invalidate the window to get it repainted. Use the function InvalidateRect.
