TMDIClient:New( <oWnd>, <nSubMenu>, <nIdChildFirst>, <oBrush>,;
                            <lVscroll>, <lHScroll> ) -> oWndClient

------------------------------------------------------------------------------


 PARAMETER:

  <oWnd>          The Parent Window object of the MDI Client.

  <nSubMenu>      Is the Position of the PopUp Menue where Windows will
                  report the currently opened Child Windows. 

  <nIdChildFirst> Is the index of the first MDI child window created.
                  Windows increments the identifier for each additional MDI 
                  child that the application creates, and reassigns 
                  identifiers when the application destroys a window to 
                  keep the range of identifiers continuous. 
                  These identifiers are used in WM_COMMAND messages to 
                  the MDI frame window when a child window is selected from 
                  the Window menu; they should not conflict with any other 
                  command identifiers. 

  <oBrush>        Brush Object that paints the Client Area of the Window.
                  If this Parameter is skipped, then a default Brush ist used

  <lVScroll>      Flag: create vertical scrollbar

  <lHScroll>      Flag: create horizontal scrollbar



 DESCRIPTION:

  This constructor method creates and initializes a TMDIClient object.
  It is called from the MDI-Parent window constructor, so you might
  want to read the  DEFINE WINDOW MDI  chapter first.

  To initialize this object a CLIENTCREATESTRUCT structure is created. 
  It contains information about the menu and first MDI child window. 
  A pointer to this structure is passed to CreateWIndow() when 
  the MDI client window is created.
