  Description
 
  The CMDIChildWnd class provides the functionality of a Windows multiple
  document interface (MDI) child window, along with data and methods to
  manipulate the window. An MDI child window looks much like a typical
  application window, except that the MDI child window lacks a menu. The
  menu on the main application window applies to MDI child windows.
 
  To create a useful MDI child window for your application, derive a class
  from CMDIChildWnd. Add member variables to the derived class to store
  data specific to your application. Implement message-handler member
  functions and a message map in the derived class to specify what happens
  when messages are directed to the window.
 
  You create an MDI child window in two steps. First, call the constructor
  CMDIChildWnd to construct the CMDIChildWnd object, then call the
  ◄Create► member function to create the MDI child window and attach it to
  the CMDIChildWnd object.
 
  Construction can be a one-step process in a derived class. Write a
  constructor for the derived class and call Create from  within the
  constructor.
 
  When the user terminates your MDI child window, destroy the CMDIChildWnd
  object, or call the DestroyWindow member function, which CMDIChildWnd
  inherits from class CWnd, to remove the CMDIChildWnd and destroy its
  data structures. If you allocate any memory in the CMDIChildWnd object,
  override the CMDIChildWnd destructor to dispose of the allocations.
