Depends whos OnCommand you are overriding. You should override CFrameWnd's.
But anyway, things are generally not done that way. Most of the time you
would let OnCommand dispatch the message automatically.
You see for every Menu item you want to handle you would have a
ON_COMMAND(id,MemberFunc) entry in your message map, and an
ON_UPDATE_COMMAND_UI(id, memberfunc) if you want to control whether the menu
is enabled, disabled, checked or what not.
