• The first time you save the resource project, you
  will be prompted to add the file to the project.
  You are adding a header file with resource

• switch (wParam)
• case CM_EXIT / Menu Item ID
  /
• DestroyWindow ( hWnd )
• case CM_ORDER / Menu Item ID /
• MessageBox( hWnd, "You Want to Order Pizza!",
  "Pizza Order",
• MB_OK MB_ICONEXCLAMATION)
• default
• return ( DefWindowProc ( hWnd, message, wParam,
  lParam ) )

Include Your New Header File In Your Program

• Add the following preprocessor directive to your
  program code
• include projXX.h

10
Thats All You Have To Do

• Once you have included the header file that
  contains the IDs for your resources and the Menu
  Name is part of the class description for your
  window class, the CreateWindow function does not
  need the menu name again. NULL is used as the
  argument for a menu or child window when the
  class defined menu is to be used. Actually, the
  argument in the CreateWindow function for the
  menu or child window (argument 9) is used to
  override the class menu if necessary.
