Requires subclassing:

Option Explicit


Private Sub Form_Load()
   Show
'    frmMenuSub.Show
   Call sGetMenuHandles(Me.hWnd)
   gProcOld = SetWindowLong(hWnd, GWL_WNDPROC, AddressOf fMenuProc)
End Sub

Private Sub Form_Unload(Cancel As Integer)
   Call SetWindowLong(hWnd, GWL_WNDPROC, gProcOld)
End Sub

Module code:

Option Explicit
Public gProcOld As Long
Public x As Long
Public y As Long

Public Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (Destination As Any, Source As Any,
ByVal Length As Long)
Public Declare Function GetMenu Lib "user32" (ByVal hWnd As Long) As Long
Public Declare Function GetMenuItemID Lib "user32" (ByVal hMenu As Long, ByVal nPos As Long) As Long
Private mMenuIDs() As Long
Dim mhMenu As Long
Dim mhSubMenu As Long

Public Const GWL_WNDPROC = (-4)
Public Const WM_MENUSELECT = &H11F


Public Const MF_BYCOMMAND& = &H0&
Public Const MF_BYPOSITION& = &H400&


Public Declare Function GetMenuString Lib "user32" Alias "GetMenuStringA" (ByVal hMenu As Long, ByVal
wIDItem As Long, ByVal lpString As String, ByVal nMaxCount As Long, ByVal wFlag As Long) As Long


Public Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hWnd As Long, ByVal
nIndex As Long, ByVal dwNewLong As Long) As Long
Private Declare Function CallWindowProc Lib "user32" Alias "CallWindowProcA" (ByVal lpPrevWndFunc As
Long, ByVal hWnd As Long, ByVal Msg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long

Public Function fMenuProc(ByVal hWnd As Long, ByVal iMsg As Long, ByVal wParam As Long, ByVal lParam
As Long) As Long
   Dim str As String
   Dim words(1 To 2) As Integer
   Dim strCaption As String
   Dim lngRet As Long
   If iMsg = WM_MENUSELECT Then
       
       'Stop
       x = wParam
       y = lParam
       
       'frmMenuSub.List1.AddItem Format(x)
       Debug.Print Format(x), y
       
       CopyMemory words(1), x, 4
       
       strCaption = String(255, 0)
       'Low word has MnuID
       If words(1) = -1 Then
           'Head menu
           lngRet = GetMenuString(mhMenu, words(1), strCaption, 255, MF_BYCOMMAND)
       Else
           'Submenu
           lngRet = GetMenuString(mhSubMenu, words(1), strCaption, 255, MF_BYCOMMAND)
       End If
       strCaption = Left$(strCaption, lngRet)
       

       
       
       Select Case strCaption

       Case "bbb"
           str = "BBB"
       Case "ccc"
           str = "CCC"
       Case "ddd"
           str = "DDD"
       End Select




       frmMenu.Label1 = str
   End If
   
   fMenuProc = CallWindowProc(gProcOld, hWnd, iMsg, wParam, lParam)
End Function



Public Sub sGetMenuHandles(hWnd As Long)
   
   mhMenu = GetMenu(hWnd)
   mhSubMenu = GetSubMenu(mhMenu, 0)
       

End Sub

You would have to tailor it to your app.

Ok, hopefully I'll still be receiving notifications.  There is a bug in EE that turns off some notifications after an answer is accepted.  My email address is in my profile if you need help and I'm not responding here.
