The EnableMenuItem function enables, disables, or grays the given menu item.
BOOL EnableMenuItem(
HMENU hMenu, // handle of menu
UINT uIDEnableItem, // menu item to enable, disable, or gray
UINT uEnable // menu item flags
);
Parameters
hMenu
Identifies the menu.
uIDEnableItem
Specifies the menu item to be enabled, disabled, or grayed, as determined by the uEnable parameter. This parameter specifies an item in a menu bar or in a pop-up menu.
uEnable
Specifies flags that control the interpretation of the uIDEnableItem parameter and indicate whether the menu item is enabled, disabled, or grayed. This parameter must be a combination of either MF_BYCOMMAND or MF_BYPOSITION and MF_ENABLED, MF_DISABLED, or MF_GRAYED.
Value Meaning
MF_BYCOMMAND Indicates that uIDEnableItem gives the identifier of the menu item. If neither the MF_BYCOMMAND nor MF_BYPOSITION flag is specified, the MF_BYCOMMAND flag is the default flag.
MF_BYPOSITION Indicates that uIDEnableItem gives the zero-based relative position of the menu item.
MF_DISABLED Indicates that the menu item is disabled, but not grayed, so it cannot be selected.
MF_ENABLED Indicates that the menu item is enabled and restored from a grayed state so that it can be selected.
MF_GRAYED Indicates that the menu item is disabled and grayed so that it cannot be selected.
Return Value
The return value specifies the previous state of the menu item (it is either MF_DISABLED, MF_ENABLED, or MF_GRAYED). If the menu item does not exist, the return value is 0xFFFFFFFF.
Remarks
An application must use the MF_BYPOSITION flag to specify the correct menu handle. If the menu handle of the menu bar is specified, the top-level menu item (an item in the menu bar) is affected. To set the state of an item in a pop-up or nested pop-up menu by position, an application must specify the handle of the pop-up menu.
When an application specifies the MF_BYCOMMAND flag, Windows checks all pop-up items that are subordinate to the menu identified by the specified menu handle. Therefore, unless duplicate menu items are present, specifying the menu handle of the menu bar is sufficient.
