Comments
 
More than one attribute can be set with a single message by combining the
attributes to set in the rgfMask parameter and their new values in the
rgfData parameter.
 
Example
 
The following 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.
 
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));
 
Return Value
 
The return value is TRUE if the operation is successful or FALSE if an error
occurs.
