Creation and use of menus:
Before using the menu, it is worth mentioning that the window with the menu must be a popup-up or overlapped style, which may have a menu.
There are three methods for the creation of the menu: 1. Specify the identifier of the menu resource in WindowClass; 2. Specify the menu handle in the CREATEWINDOWEX function parameter; The menu bar of the program.
The menu is included: add a new menu item to the existing menu, delete one of the menu, so that the menu item is selected, so that the menu item is invalid, create a floating menu, add, delete options to the Windows system menu and many more.
There are two ways to locate menu items: 1. Use the unique identifier of the menu item; 2, with the logical index of the menu item.
The logical index of the menu item is specified, and the items in the menu bar are from left to right indexes are 0, 1, 2 ..., the items in the pop-up menu are 0, 1, 2 ....
If you want to get the handle of a menu, you will get the handle by getting the handle of the menu strip first. E.g:
HMENU = GetMenu (hwnd); // hwnd is the window handle
HPopupMenu = getSubmenu (HMENU, 0); // 0 represents the first option of the menu
Sample 1: Various operations in demo menu
// begin.cpp: Defines the entry point for the application.
