My solution
    Public Function GetTableColumnNames() As Boolean
        Form1.ListBox1.Items.Clear()
        _MDFFileName = String.Format("{0}.mdf", _DatabaseName)
        _sqlConnectionString = String.Format("Data Source=(LocalDB)\v11.0;AttachDBFileName={1};Initial Catalog={0};Integrated Security=True;", _DatabaseName, Path.Combine(_DatabaseDirectory, _MDFFileName))
        Dim cn As New SqlConnection(_sqlConnectionString)
        'put the table name in brackets in case it has spaces in it
        Dim SQLString As String = "SELECT * FROM [" & _TableName & "]"
        Try
            cn.Open()
            Dim cmd As New SqlCommand(SQLString, cn)
            Dim rdr As SqlDataReader =
            cmd.ExecuteReader(CommandBehavior.KeyInfo)
            Dim tbl As DataTable = rdr.GetSchemaTable
            'This shows all of the information you can access about each column.
            For Each col As DataColumn In tbl.Columns
                Form1.ListBox1.Items.Add(col.ColumnName)
                Debug.Print("col name = " & col.ColumnName & ", type = " & col.DataType.ToString)
            Next
            'Get each column.
            For Each row As DataRow In tbl.Rows
                Form1.ListBox1.Items.Add(row("ColumnName"))
            Next
            rdr.Close()
        Catch
            MessageBox.Show("Error opening the connection to the database.")
        Finally
            cn.Close()
        End Try
        Return _Success
    End Function
