CMenu::CreateMenu

BOOL CreateMenu( );

Return Value

Nonzero if the menu was created successfully; otherwise 0.

Remarks

Creates a menu and attaches it to the CMenu object.

The menu is initially empty. Menu items can be added by using the AppendMenu or InsertMenu member function.

If the menu is assigned to a window, it is automatically destroyed when the window is destroyed.

Before exiting, an application must free system resources associated with a menu if the menu is not assigned to a window. An application frees a menu by calling the DestroyMenu member function.

Example

// The code fragment below shows how to create a new menu for the
// application window using CreateMenu() and CreatePopupMenu().
// Then, the created menu will replace the current menu of the
// application. The old menu will be destroyed with DestroyMenu().
// NOTE: The code fragment below is done in a CFrameWnd-derived class.

// Create a new menu for the application window.
VERIFY(m_NewMenu.CreateMenu());

// Create a "File" popup menu and insert this popup menu to the
// new menu of the application window. The "File" menu has only
// one menu item, i.e. "Exit".
VERIFY(m_FileMenu.CreatePopupMenu());
m_FileMenu.AppendMenu(MF_STRING, ID_APP_EXIT, (LPCTSTR)"E&xit");
m_NewMenu.AppendMenu(MF_POPUP, (UINT) m_FileMenu.m_hMenu, "&File");

// Remove and destroy old menu
SetMenu(NULL);
CMenu* old_menu = CMenu::FromHandle(m_hMenuDefault);
old_menu->DestroyMenu();

// Add new menu.
SetMenu(&m_NewMenu);

// Assign default menu
m_hMenuDefault = m_NewMenu.m_hMenu;
