查看msdn
CMenu::EnableMenuItem
UINT EnableMenuItem( UINT nIDEnableItem, UINT nEnable );
Return Value
Previous state (MF_DISABLED, MF_ENABLED, or MF_GRAYED) or –1 if not valid.
Parameters
nIDEnableItem
Specifies the menu item to be enabled, as determined by nEnable. This parameter can specify pop-up menu items as well as standard menu items.
nEnable
Specifies the action to take. It can be a combination of MF_DISABLED, MF_ENABLED, or MF_GRAYED, with MF_BYCOMMAND or MF_BYPOSITION. These values can be combined by using the bitwise OR operator. These values have the following meanings:
MF_BYCOMMAND Specifies that the parameter gives the command ID of the existing menu item. This is the default.
MF_BYPOSITION Specifies that the parameter gives the position of the existing menu item. The first item is at position 0.
MF_DISABLED Disables the menu item so that it cannot be selected but does not dim it.
MF_ENABLED Enables the menu item so that it can be selected and restores it from its dimmed state.
MF_GRAYED Disables the menu item so that it cannot be selected and dims it.
