  CClientDC( CWnd* pWnd );
  throw( CResourceException );
 
  Parameter   Description
 
  <pWnd>      The window whose client area the device context object will
              access.
 
  Remarks
 
  Constructs a CClientDC object that accesses the client area of the
  ◄CWnd► pointed to by <pWnd>. The constructor calls the Windows function
  ◄GetDC►.
 
  An exception (of type CResourceException) is thrown if the Windows GetDC
  call fails. A device context may not be available if Windows has already
  allocated all of its available device contexts. Your application
  competes for the five common display contexts available at any given
  time under Windows.
