分清几个概念

<1>“主菜单” 和 “顶层菜单” 是一个意思。

<2>主菜单中的项目叫做 “弹出菜单” 或者 “子菜单”。

<3>弹出菜单的项目可以是另外一个弹出菜单。

<4>菜单的状态：启用，禁用，无效化，无效化跟前两者的区别是灰色显示文字。

（1）菜单消息

<1>WM_INITMENU

        wParam,   // handle to menu (HMENU)
        lParam    // not used

<2>WM_MENUSELECT

菜单项被选中的时候

       wParam,   // menu item (UINT) and flags (UINT)
       lParam    //handle to menu (HMENU)

其中

LOWORD(wParam)		//被选中项目：菜单ID或者弹出式菜单句柄
HIWORD(wParam)		//选择旗标

旗标是MF_GRAYED、MF_DISABLED、MF_CHECKED、MF_BITMAP、MF_POPUP、MF_HELP、MF_SYSMENU和MF_MOUSESELECT的集合。

<3>WM_INITMENUPOPUP

 当下拉菜单被激活的时候就会发出这样的消息

WPARAM wParam,   // handle to menu (HMENU)
LPARAM lParam    // item position and indicator

<4>WM_COMMAND

表示使用者已经从菜单中选择了一个被启用的菜单项，

LOWORD (wParam)：菜单命令ID

HIWORD(wParam)：0

lParam：0

<5>WM_MENUCHAR

（2）菜单项中的字母的下划线

把字母前面加&字符，就可以出现字母下划线的效果，当用Alt键+ 字符，可以快捷的弹出子菜单，或者执行菜单项命令。

对应属性

（3）菜单项的选中和去选中状态

CheckMenuItem(hMenu, iSelection, MF_UNCHECKED) ;
CheckMenuItem(hMenu, iSelection, MF_CHECKED) ;

（4）关于Menu的函数

         关于菜单的操作从大体方向上看无外乎增删改查四种操作。

4.1    HMENUCreateMenu(VOID);

4.2   BOOL AppendMenu( HMENU hMenu, // handle to menu

                         UINT uFlags,                            //menu-item options

                         UINT_PTR uIDNewItem,       // identifier, menu, or submenu

                         LPCTSTR lpNewItem         //menu-item content);

其中uFlags 可以是：

MF_BITMAP，MF_OWNERDRAW，MF_STRING

示例：

AppendMenu         (hMenuPopup, MF_STRING, IDM_APP_EXIT,"E&xit") ;

AppendMenu         (hMenu, MF_POPUP, hMenuPopup,"&File") ;

4.3    BOOLInsertMenu(  HMENU hMenu,          // handle to menu

                         UINT uPosition,       // item that new item precedes

                         UINT uFlags,          // options

                         UINT_PTR uIDNewItem,  // identifier, menu, or submenu

                         LPCTSTR lpNewItem     // menu item content);

这个函数和AppendMenu相比除了uPosition这个参数外，其余完全相同

uPosition：表示被插的位置索引或者菜单ID，具体是哪一个取决于uFlags中是MF_BYCOMMAND还是MF_BYPOSITION。

uIDNewItem：插入项是命令项的时候表示的是ID，插入项是菜单的时候表示的菜单句柄。

lpNewItem：    插入项的内容，具体取决于uFlags中包含的MF_BITMAP，MF_STRING，MF_OWNERDRAW

注意：不能放在一起的命令组合

• MF_BYCOMMAND and MF_BYPOSITION
• MF_DISABLED, MF_ENABLED, and MF_GRAYED
• MF_BITMAP, MF_STRING, MF_OWNERDRAW, and MF_SEPARATOR
• MF_MENUBARBREAK and MF_MENUBREAK
• MF_CHECKED and MF_UNCHECKED

4.4    BOOLInsertMenuItem(  HMENU hMenu,           // handle to menu

                UINT uItem,            // identifier or position

                BOOL fByPosition,      // meaning of uItem

                LPCMENUITEMINFO lpmii  // menu item information);

typedef struct tagMENUITEMINFO {
  UINT    cbSize; 
  UINT    fMask; 
  UINT    fType; 
  UINT    fState; 
  UINT    wID; 
  HMENU   hSubMenu; 
  HBITMAP hbmpChecked; 
  HBITMAP hbmpUnchecked; 
  ULONG_PTR dwItemData; 
  LPTSTR  dwTypeData; 
  UINT    cch; 
  HBITMAP hbmpItem;
} MENUITEMINFO, *LPMENUITEMINFO;

4.5   BOOL RemoveMenu(  HMENU hMenu,     // handle to menu

                UINT uPosition, // menu item identifier or position

                UINT uFlags     // options);

4.6    BOOLModifyMenu(  HMENU hMnu,           // handle to menu

                UINT uPosition,       // menu item to modify 

                   UINTuFlags,          // options

                UINT_PTR uIDNewItem,  // identifier, menu, or submenu

                 LPCTSTR lpNewItem     // menu item content);

4.7    BOOLDeleteMenu(  HMENU hMenu,     // handle to menu

                UINT uPosition,  // menu item identifier or position

                UINT uFlags      // option);

删除菜单项，如果菜单项时弹出菜单，那么就会释放菜单句柄所指向的内存。

4.7    BOOLDrawMenuBar(  HWND hWnd  // handle to window);

4.8    HMENUGetSubMenu(  HMENU hMenu,  // handle to menu

                         int nPos      // menu item position);

当菜单栏发生变化时候，必须调用这个函数重新绘制菜单//经常验证，未必

（6）右键菜单

右键菜单跟一般的菜单没什么区别，只是弹出的时候，需要用到这个函数

BOOLTrackPopupMenu(  HMENU hMenu,         // handle to shortcut menu
  UINT uFlags,         // options 
  int x,               // horizontal position
  int y,               // vertical position
  int nReserved,       // reserved, must be zero
  HWND hWnd,           // handle to owner window
  CONST RECT *prcRect  // ignored);

其中的uFlags参数指定了菜单中菜单中的对齐方式，左键右键选定菜单项

TPM_CENTERALIGN，TMP_LEFTALIGN，TMP_RIGHTALIGN

TPM_BOTTOMALIGN, TPM_TOPALIGN, TPM_VCENTERALIGN

TPM_LEFTBUTTPON,TPM_RIGHTBUTTON

TPM_NONOTIFY, TPM_RETURNCMD

（7）系统菜单

获取系统菜单句柄

HMENU GetSystemMenu( 

         HWNDhWnd,    // handle to window

       BOOL bRevert  // reset option);

其中bRevert = FALSE时候，表示，复制系统的菜单，并且返回复制菜单的句柄，这个菜单可以进行修改。当bRevert = TRUE 时，设置系统菜单为默认的原始状态，并且函数返回值是NULL.

一下示例是一个完全依靠code不依赖创建资源的菜单demo，其中包含菜单栏，右键菜单，系统菜单，可以对菜单进行动态的修改，删除，添加操作。
