Changes information about a menu item.

Syntax

BOOL SetMenuItemInfoA(
  [in] HMENU            hmenu,
  [in] UINT             item,
       BOOL             fByPositon,
  [in] LPCMENUITEMINFOA lpmii
);

Parameters

[in] hmenu

Type: HMENU

A handle to the menu that contains the menu item.

[in] item

Type: UINT

The identifier or position of the menu item to change. The meaning of this parameter depends on the value of fByPosition.

fByPositon

[in] lpmii

Type: LPMENUITEMINFO

A pointer to a MENUITEMINFO structure that contains information about the menu item and specifies which menu item attributes to change.

Return value

Type: BOOL

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, use the GetLastError function.

Remarks

The application must call the DrawMenuBar function whenever a menu changes, whether the menu is in a displayed window.

In order for keyboard accelerators to work with bitmap or owner-drawn menu items, the owner of the menu must process the WM_MENUCHAR message. See Owner-Drawn Menus and the WM_MENUCHAR Message for more information.

Examples

For an example, see Example of Owner-Drawn Menu Items.

Note

The winuser.h header defines SetMenuItemInfo as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
