C# to VB.net Invoke error

Hey all I am trying to figure out how to get the code below to work in VB.net. I already converted it from C# to VB.net:

Code:

---

Dim dt As New DataTable()
    Dim dr As DataRow

    dt.Columns.Add("Name")
    dt.Columns.Add("Number")

    For Each item As KeyValuePair(Of String, String) In vCardReader.dicNumName
        dr = dt.NewRow()
        dr(0) = item.Value
        dr(1) = item.Key
        dt.Rows.Add(dr)
    Next

    If InvokeRequired Then
                Me.Invoke(New MethodInvoker(
                        Sub()
                            contactNameNumList.DataSource = dt
                            contactNameNumList.AllowUserToResizeRows = False
                            contactNameNumList.AllowUserToResizeColumns = False
                            contactNameNumList.AllowUserToOrderColumns = False
                            contactNameNumList.CellBorderStyle = DataGridViewCellBorderStyle.None
                            contactNameNumList.Columns(0).Width = 30
                            contactNameNumList.Columns(1).Width = contactNameNumList.Width / 2 - 25
                            contactNameNumList.Columns(2).Width = contactNameNumList.Width / 2 - 25
                        End Sub))
            Else
                contactNameNumList.DataSource = dt
                contactNameNumList.AllowUserToResizeRows = False
                contactNameNumList.AllowUserToResizeColumns = False
                contactNameNumList.AllowUserToOrderColumns = False
                contactNameNumList.CellBorderStyle = DataGridViewCellBorderStyle.None
                contactNameNumList.Columns(0).Width = 30
                contactNameNumList.Columns(1).Width = contactNameNumList.Width / 2 - 25
                contactNameNumList.Columns(2).Width = contactNameNumList.Width / 2 - 25
            End If

---

However, when I run the program, the error I get for the above code is this:

> Object reference not set to an instance of an object.

How can I correct this error?
