Basic classes

CObject - macros accompanying this class allow classes derived from CObject to
  • get their class' name at run time
  • get their class' object size at run time
  • create an object of this class without knowing the class' name
  • store and retrieve an instance of this class to an archive device without knowings its name
CCmdTarget - classes derived from this can receive and process command messages from the application's menu or toolbar(s)

CWnd - derived from CCmdTarget, and can perform it's functions too
all other MFC fn.s that control a window (creating, maintaining) are derived from CWnd

  • SDI (Single Document Interface) - load and edit one application at a time + use all the four base classes
  • MDI ( Multiple Document Interface ) - load and edit several documents at once + use all four base classes + CMDIFrameWnd and CMDIChildWnd ( 2 derivations of CFrameWnd )

Document Template - defines what frame, document and view class to create when the application opens a document
create an object of CSingleDocTemplate / CMultiDocTemplate class and initialize with three class pointers
