Thread: enabling and disabling menu items

hi

I have searching for a few days now to try and find out how to disable and enable menuitems becuase i am creating a chat program but when they connect i want the connect option in the menu to gray out or be disabled so they cant use it and when they disconnect for the option to be enabled so they can use it.

i am using dev c++ and win xp pro

thx in advance

Code:

BOOL EnableMenuItem(
    HMENU hMenu,
    UINT uIDEnableItem,
    UINT uEnable
);

hMenu
    [in] Handle to the menu. 

uIDEnableItem
    [in] 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, menu, or submenu.

uEnable
    [in] Controls 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. 

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.
