Subj : Borland C++ 5.02 and writing Windows code

Greetings,

I'm pretty much a newbie to writing Window's code, though not so much
to C++.  I've been following the chapters in the book "Windows 2000
Programming from the Ground Up" by Herbert Schildt as I try to
assimilate all this, and I've come across a problem.

The book does things from the very basic level as far as the resource
compiler is concerned.  It doesn't take into account the Borland 5.02
IDE and the resource editor it has.  As such, I've built a very simple
menu (see the text layout)

===MENU BEGIN===

IDM_MENU1 MENU 
{
 POPUP "&File"
 {
  MENUITEM "&Select Drive", 101
  MENUITEM "E&xit", 108
 }

 POPUP "&Help"
 {
  MENUITEM "&About", 903
 }

}

===MENU END===


and a simple program to simply display a window.  Additionally, I've
added the code to include this menu as part of the window (see below).


===CODE BEGIN===
/* =======================================================================

#include <windows>

LRESULT CALLBACK WindowFunc( HWND, UINT, WPARAM, LPARAM );

char szWinName[] = "MyWin";			// name of window class
char szMenuName[] = "IDM_MENU1";		// name of menu

#define IDM_SELECT	101
#define IDM_EXIT	108
#define IDM_ABOUT	903

int WINAPI WinMain( HINSTANCE hThisInst, HINSTANCE hPrevInst,
                    LPSTR lpszArgs, int nWinMode )
{
   HWND hwnd;
   MSG msg;
   WNDCLASSEX wcl;

   // ==============================================
   // Define a window class
   // ==============================================
   wcl.cbSize = sizeof(WNDCLASSEX);

   wcl.hInstance = hThisInst;			// handle to this instance
   wcl.lpszClassName = szWinName;		// window class name
   wcl.lpfnWndProc = WindowFunc;		// window function
   wcl.style = 0;				// default style

   wcl.hIcon = LoadIcon( NULL, IDI_APPLICATION );	// large icon
   wcl.hIconSm = NULL;			// use small version of large icon
   wcl.hCursor = LoadCursor( NULL, IDC_ARROW);	// cursor style

   wcl.lpszMenuName = szMenuName;		// class menu
   wcl.cbClsExtra = 0;				// no extra memory needed
   wcl.cbWndExtra = 0;

   // ==============================================
   // Make the Window background white
   // ==============================================
   wcl.hbrBackground = (HBRUSH) GetStockObject(WHITE_BRUSH);

   // ==============================================
   // Register the window class
   // ==============================================
   if ( !RegisterClassEx(&wcl) ) return 0;


   // ==============================================
   // Now that the window class has been registered,
   // a window can be created
   // ==============================================
   hwnd = CreateWindow(
   	    szWinName, 	                // name of window class
            "DiskUse", 			// title
            WS_OVERLAPPEDWINDOW, 	// window style, normal
            CW_USEDEFAULT,		// x coordinate - let Windows decide
            CW_USEDEFAULT,		// y coordinate - let Windows decide
            CW_USEDEFAULT,		// width - let Windows decide
            CW_USEDEFAULT,		// height - let Windows decide
            NULL,			// no parent window
            NULL,			// no menu
            hThisInst,			// instance handle
            NULL			// no additional arguments
   );


   // ==============================================
   // Display the window
   // ==============================================
   ShowWindow( hwnd, nWinMode );
   UpdateWindow( hwnd );


   // ==============================================
   // Create the message loop
   // ==============================================
   while( GetMessage( &msg, NULL, 0, 0 ) )
   {
      TranslateMessage(&msg);		// translate keyboard messages
      DispatchMessage(&msg);		// return control to Windows
   }

   // ==============================================
   // Exiting the program
   // ==============================================
	return msg.wParam;

}


LRESULT CALLBACK WindowFunc( HWND hwnd, UINT message, WPARAM wParam,
LPARAM lParam )
{
	// int response;

	switch( message )
   {
   	case WM_COMMAND:
      	switch( LOWORD(wParam) )
         {
         	case IDM_SELECT:
            	MessageBox( hwnd, "SELECT", "FILE", MB_OK );
            	break;
            case IDM_EXIT:
            	MessageBox( hwnd, "EXIT", "FILE", MB_OK );
		      	PostQuitMessage(0);
            	break;
            case IDM_ABOUT:
            	MessageBox( hwnd, "ABOUT", "HELP", MB_OK );
            	break;
         }
         break;
   	case WM_DESTROY:
      	PostQuitMessage(0);
         break;
      default:
      	// ================================================
         // Windows will process any messages not specified
         // in the preceding switch statement.
      	// ================================================
      	return DefWindowProc( hwnd, message, wParam, lParam );
   }

   return 0;
}
===CODE END===


But the menu is not showing up.  Am I missing something in the Borland
IDE to "turn on" this menu?  Is there some additional code I need to
use?  Can anyone provide some direction on this?  I would greatly
appreciate it.

TIA,

Paul
