Disabling close button

Is there any way to disable (or even hide) a window caption's close button, i.e. the top right button of a ws_sysmenu style window. I can already prevent a window from closing, so that is not what I'm asking for.
I have seen MDI child windows with this button disabled, so there has to be a way?!
Since I don't ask a lot of questions, a good answer will be worth a bunch.

Use GetSystemMenu to access the Control menu for copying and modification. The GetMenuItemCount function determines the number of items in the specified menu. The RemoveMenu function deletes a menu item from the specified menu. The DrawMenuBar function redraws the menu bar of the specified window. It should be easy to compile them together.
Or simpler:
CMenu *MyMenu; MyMenu = GetSystemMenu(FALSE);
 MyMenu->EnableMenuItem(SC_CLOSE,MF_DISABLED);

Put the codes under the OnCreate() function. For MDI child windows, add member function for WM_CREATE message in CChildFrame class.
