This message sets the attributes of a menu item.

==Syntax==
<pre>
param1
    USHORT usitem;            /* Item identifier. */
    USHORT usincludesubmenus; /* Include submenus indicator. */

param2
    USHORT usattributemask; /* Attribute mask. */
    USHORT usattributedata; /* Attribute data. */
</pre>

==Parameters==
;''usitem'' (USHORT) - input: Item identifier.
;''usincludesubmenus'' (USHORT) - input: Include submenus indicator.
:TRUE: If the menu does not have an item with the specified identifier, search the submenus and subdialogs of the menu for an item with the specified identifier and set its attributes.
:FALSE: If the menu does not have an item with the specified identifier, do not search the submenus and subdialogs of the menu for an item with the specified identifier.

;''usattributedata'' (USHORT) - input: Attribute data.

==Returns==
;''rc'' (BOOL) - returns: Success indicator.
:TRUE: Successful completion
:FALSE: Error occurred

==Remarks==
The menu control window procedure responds to this message by setting the state of the specified attributes for the identified item.
:''Note'': It must be sent, not posted, to the menu control.

==Default Processing==
The default window procedure does not expect to receive this message and therefore takes no action on it, other than to set ''rc'' to the default value of FALSE.

==Examples==
This example sends an MM_SETITEMATTR message to set the IDM_LARGE menu item's state to checked, and then sends another MM_SETITEMATTR message to set the IDM_MEDIUM menu item's state to unchecked.
<pre>
WinSendMsg(hwndActionBar, MM_SETITEMATTR,
    MPFROM2SHORT(IDM_LARGE, TRUE),
    MPFROM2SHORT(MIA_CHECKED, MIA_CHECKED));
WinSendMsg(hwndActionBar, MM_SETITEMATTR,
    MPFROM2SHORT(IDM_MEDIUM, TRUE),
    MPFROM2SHORT(MIA_CHECKED, FALSE));
</pre>
