/*****************************************************************************
  DLGBARS.CPP

  Purpose: 
  	Interface for CDlgToolBar, a special type of CToolBar which does not
  	expect a parent frame window to be available, and CDlgStatusBar, which
  	does the same for CStatusBars.  This allows the control bars
  	to be used in applications where the main window is a dialog bar.

  Functions:
    CDlgToolBar::CDlgToolBar()          -- constructor
    CDlgToolBar::~CDlgToolBar()         -- destructor
    CDlgToolBar::OnIdleUpdateCmdUI()    -- WM_IDLEUPDATECMDUI handler
    
    CDlgStatusBar::CDlgStatusBar()      -- constructor
    CDlgStatusBar::~CDlgStatusBar()     -- destructor
    CDlgStatusBar::OnIdleUpdateCmdUI()	-- WM_IDLEUPDATECMDUI handler
