CheckMenuItem

  • Article

This function sets the state of the specified menu item's check mark attribute to either checked or unchecked.

DWORD CheckMenuItem(
  HMENU hmenu, 
  UINT uIDCheckItem, 
  UINT uCheck 
);

Parameters

  • hmenu
    [in] Handle to the menu of interest.
  • uIDCheckItem
    [in] Specifies the menu item whose check-mark attribute is to be set, as determined by the uCheck parameter.
  • uCheck
    [in] Specifies flags that control the interpretation of the uIDCheckItem parameter and the state of the menu item's check-mark attribute. This parameter can be a combination of either MF_BYCOMMAND, or MF_BYPOSITION and MF_CHECKED or MF_UNCHECKED.
    Value Description
    MF_BYCOMMAND Indicates that the uIDCheckItem parameter gives the identifier of the menu item. The MF_BYCOMMAND flag is the default, if neither the MF_BYCOMMAND nor MF_BYPOSITION flag is specified.
    MF_BYPOSITION Indicates that the uIDCheckItem parameter gives the zero-based relative position of the menu item.
    MF_CHECKED Sets the check-mark attribute to the checked state.
    MF_UNCHECKED Sets the check-mark attribute to the unchecked state.

Return Values

The return value specifies the previous state of the menu item (either MF_CHECKED or MF_UNCHECKED). 0xFFFFFFFF indicates that the menu item does not exist.

Remarks

An item in a menu bar cannot have a check mark.

The uIDCheckItem parameter identifies an item that opens a submenu or a command item. For an item that opens a submenu, the uIDCheckItem parameter must specify the position of the item. For a command item, the uIDCheckItem parameter can specify either the item's position or its identifier.

Requirements

OS Versions: Windows CE 1.0 and later.
Header: Winuser.h.
Link Library: Menu.lib.
