Run time control question

[XaviGR]

I'm working on a user defined control, with a simple label.

My control has this function:

Sub AddRow(ByVal Texto As String)

When I execute AddRow("Sample") I want that my control adds a label to
an array and sets the text to the latest label in the array.

This is what I've done:

Public Row(0) As String
Public List() As Label

Sub AddRow(ByVal Texto As String)
ReDim Preserve Row(UBound(Row) + 1)

Row(UBound(Row)) = Texto

Dim NewLabel As New Label

NewLabel.Name = Texto
NewLabel.Size = New System.Drawing.Size(39, 13)
NewLabel.TabIndex = 0
NewLabel.Text = Texto
NewLabel.Visible = True
NewLabel.Top = UBound(Row) * 10

Dim List(UBound(Row)) As Label
List(UBound(Row)) = NewLabel
Controls.Add(NewLabel)

End Sub

But I don't know what to do to add all new created labels to the public
array List

Of course, in my code, each time the function is called the List Array
is cleared, but I don't know how to use the Public List (If I delete
the "Dim List(UBound(Row)) As Label" then I get the error: Object
reference not set. How can I set this instance reference?

Thanks a lot.
