        cmd.Parameters.Add("Sub_total", OleDbType.VarChar, 50).Value = ListView1.Items(i).SubItems(6).Text
        ' !!


End Sub

End Class

I created a listview with three columns for FirstName, LastName and Age. To insert all rows of the listview into mytable I could code

For Each row As ListViewItem In ListView1.Items
    Dim query As String = "insert into mytable (FirstName,LastName,Age) Values(" &
                          "'" & row.SubItems(0).Text & "'," &
                          "'" & row.SubItems(1).Text & "'," &
                                row.SubItems(2).Text &
    'execute query here

Naturally, you would execute the query instead of writing the query to the debug output. This code does no error checking (Try/Catch) for possible problems like duplicate records, etc. Note that in the database, the first two fields would be stared as strings and the third as a number. That is why the third field does not have single quotes around it in the query.
