Frame Window Classes (Architecture)
In document/view architecture, frame windows are windows that contain a view window. They also support having control bars attached to them.
In multiple document interface (MDI) applications, the main window is derived from CMDIFrameWnd. It indirectly contains the documents' frames, which are CMDIChildWnd objects. The CMDIChildWnd objects, in turn, contain the documents' views.
In single document interface (SDI) applications, the main window, derived from CFrameWnd, contains the view of the current document.

CMDIChildWnd
The base class for an MDI application's document frame windows.
