How to display a minimized MDIChild as large icon

Hi,
i have a standard MFC MDI application. If i minimize a view (exactly MDIChildFrame containing a view) i want that it is displayed as a large icon rather than a small titlebar containing a small icon and some restore/maximize/close buttons. The icon for the view has two pictures (16x16 and 32x32). But i don't know how to display the minimized window only with the large icon.

Thanks in advance!
