Hi!

I'll employ maximum brevity, so that FAQ could be updated if appropriate.

Add the following code fragments to the indicated places in the WinProc()
of an application, or the FrameWinProc() of a MDI application.
    ...
  case WM_CREATE:
    hWndClient = CreateWindow( "MDIClient",...,
          WS_CHILD|WS_VISIBLE|WS_CLIBSIBLINGS|WS_HSCROLL|WS_VSCROLL,... );
    hWndStatus = CreateWindow( "Static",...,
          WS_CHILD|WS_VISIBLE|SS_LEFT|SS_NOPREFIX,... );
    ...
  case WM_SIZE:
    GetClientRect( hWnd,&rect );
    // Calculate DIVIDING_LINE s.t. rect.top < DIVIDING_LINE < rect.bottom
    // One choice: DIVIDING_LINE = rect.bottom-GetSystemMetrics(SM_CYMENU);
    MoveWindow( hWndClient,rect.left,rect.top,
          rect.right,DIVIDING_LINE,TRUE );
    MoveWindow( hWndStatus,rect.left,DIVIDING_LINE,
          rect.right,rect.bottom,TRUE );
    ...
    break;  // Do *not* pass to DefFrameProc() of a MDI application !!!
    ...
    // To change the status text:
    SendMessage( hWndStatus,WM_SETTEXT,0,(LONG)(LPSTR)szStatusText );

Notes:
  - For non-MDI applications, all references to hWndClient above will simply
    be removed.
  - Menu selection can be tracked by setting the status text at a response to
    the WM_MENUSELECT message.
  - To draw a line between status bar and the rest of the client area, the
    DIVIDING_LINE should be adjusted in either MoveWindow() call to leave a
    gap between, which is called InvalidateRect() for, and actually being
    painted in response to the WM_PAINT .
  - The parent window should have WS_CLIPCHILDREN style bit set.
