    You should really do this in an object orientated way. You add the object into the listbox, and take it back out.

    Here is one method where we populate the ListBox with a DataTable, get information back then remove a row. I kept things simple which can easily be expanded upon.

    Private Sub LoadListBox()
        Dim dt As New DataTable
        dt.Columns.Add(New DataColumn With
                       {.ColumnName = "LeftSide", .DataType = GetType(String)})
        dt.Columns.Add(New DataColumn With
                       {.ColumnName = "RightSide", .DataType = GetType(String)})
        dt.Columns.Add(New DataColumn With
                       {.ColumnName = "DisplayText", .DataType = GetType(String),
                        .Expression = "LeftSide + '  ' + RightSide"})
        dt.Rows.Add(New Object() {"[" & Now.ToString & "]", "A"})
        ListBox1.DataSource = dt
        ListBox1.DisplayMember = "DisplayText"
    End Sub
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim dt As DataTable = CType(ListBox1.DataSource, DataTable)
        dt.Rows.Add(New Object() {"[" & Now.AddHours(1).ToString & "]", "B"})
        MessageBox.Show(CType(ListBox1.Items(0), DataRowView). _
                Row.Field(Of String)("LeftSide").Replace("[", "").Replace("]", ""))
    End Sub
