Populating unique data from sheet to form

[ellipsism]

Hello, I'm wondering if there is an easy way of populating the unique records in an excel column to a listbox or combobox. I am thinking of doing something like

    For r = 2 To 128
            With CB_List
                For n = 0 To .ListCount
                    If .List(n, 0) = Sheets("Testsheet").Cells(r, "U") Then
                        Exit For
                    End If
                Next n
                If n = .ListCount + 1 Then
                    .AddItem
                    .ColumnCount = 1
                    .List(.ListCount - 1, 0) = Sheets("Testsheet").Cells(r, "U")
                End If
 
            End With
    Next r
 

Which does not work right now, but will eventually. I just thought there must be a simpler way. Does anyone know if there is such a way?

Best regards, Johan

Add the items from the Excel list to a Collection.
A Collection object will not accept duplicates.
Then add the contents of the Collection to the listbox.
