Errata for Revision I

ENTRY 1: ************************************************************************

In the T3DCONSOLE2.CPP (16-bit functionality for window setup) code in the book there 
are a couple changes that were made to make the code work with Win2000/XP. The changes 
are all on the CD, but the code in the book has the old version. The code of interest
is this section below:

// create the window
if (!(hwnd = CreateWindowEx(NULL,                  // extended style
                            WINDOW_CLASS_NAME,     // class
			    WINDOW_TITLE, // title
			    (WINDOWED_APP ? (WS_OVERLAPPED | WS_SYSMENU | WS_CAPTION) : (WS_POPUP | WS_VISIBLE)), 
			    0,0,	  // initial x,y
			    WINDOW_WIDTH,WINDOW_HEIGHT,  // initial width, height
			    NULL,	  // handle to parent 
			    NULL,	  // handle to menu
			    hinstance,// instance of this application
			    NULL)))	// extra creation parms
return(0);


// ******** IN THE ABOVE CODE THE WS_CAPTION NOW REPLACES WS_VISIBLE


// save main window handle
main_window_handle = hwnd;

if (WINDOWED_APP)
{
// now resize the window, so the client area is the actual size requested
// since there may be borders and controls if this is going to be a windowed app
// if the app is not windowed then it won't matter
RECT window_rect = {0,0,WINDOW_WIDTH-1,WINDOW_HEIGHT-1};

// ********* I HAVE ADDED A "-1" TO THE WIDTH AND THE HEIGHT AS SHOWN ABOVE


// make the call to adjust window_rect
AdjustWindowRectEx(&window_rect,
     GetWindowStyle(main_window_handle),
     GetMenu(main_window_handle) != NULL,
     GetWindowExStyle(main_window_handle));

// save the global client offsets, they are needed in DDraw_Flip()
window_client_x0 = -window_rect.left;
window_client_y0 = -window_rect.top;

// now resize the window with a call to MoveWindow()
MoveWindow(main_window_handle,
           0, // x position
           0, // y position
           window_rect.right - window_rect.left, // width
           window_rect.bottom - window_rect.top, // height
           TRUE);

// ***** THE X AND Y POSITION ARE NOW 0 RATHER THAN THE DEFAULT VALUES
