CheckMenuItem function (winuser.h)
[CheckMenuItem is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions. Instead, use SetMenuItemInfo. ]
Sets the state of the specified menu item's check-mark attribute to either selected or clear.
Syntax
DWORD CheckMenuItem(
[in] HMENU hMenu,
[in] UINT uIDCheckItem,
[in] UINT uCheck
);
Parameters
[in] hMenu
Type: HMENU
A handle to the menu of interest.
[in] uIDCheckItem
Type: UINT
The menu item whose check-mark attribute is to be set, as determined by the uCheck parameter.
[in] uCheck
Type: UINT
The 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.
Return value
Type: DWORD
The return value specifies the previous state of the menu item (either MF_CHECKED or MF_UNCHECKED). If the menu item does not exist, the return value is –1.
Remarks
An item in a menu bar cannot have a check mark.
The uIDCheckItem parameter identifies a item that opens a submenu or a command item. For a 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.
