Quello che dicevo a TT era questo:
Private Function getRequery(actCombo As Access.ComboBox)
Dim mCbo As Access.ComboBox
Dim bRequery As Boolean
For Each mCbo In mCCombo
If bRequery Then
mCbo.Value = Null
mCbo.Requery
If mCbo.ListCount <= 1 Then mCbo = mCbo.ItemData(0)
Else
bRequery = mCbo Is actCombo ' <------- essendo 2 oggetti, EquiType si possono confrontare
End If
'Next I
Next
Set mCbo = Nothing
End Function
