Dim boolExists As Boolean = False
Dim values As ArrayList = New ArrayList
For Each numBox As NumericUpDown In Me.Controls
If TypeOf (numBox) Is NumericUpDown Then
If values.Contains(numBox.Value) Then
boolExists = True
Exit For
Else
values.Add(numBox.Value)
End If
End If

values = Nothing
Return boolExists
