一个access表：test 有三个键：Id(整数类型)  tname（字符串类型） add（字符串类型）
表中有20条完整的记录，请问如何连接数据库，（select * from test）并在连接后获取第10行的Tname列的数据？

我是这么连接的 如下：
Dim strconn As String = "Provider=Microsoft.jet.oledb.4.0;data source=" & My.Application.Info.DirectoryPath & "\test.mdb;persist security info=false"
Dim objconn As New Data.OleDb.OleDbConnection(strconn)
Dim s As String = "select * from test order by id desc"
Dim objReader As Data.OleDb.OleDbDataAdapter
objconn.Open() '打开数据库连接
Dim dr As OleDb.OleDbDataReader
Dim cmdQx As System.Data.OleDb.OleDbCommand = New System.Data.OleDb.OleDbCommand(s, objconn)
dr = cmdQx.ExecuteReader

后面不知道怎么进行操作了 ？

刚学不久，请高手指点迷津

Dim strconn As OleDb.OleDbConnection
strconn = "Provider=Microsoft.jet.oledb.4.0;data source=" & My.Application.Info.DirectoryPath & "\test.mdb;persist security info=false"
objconn.Open() '打开数据库连接
Dim s As String = "select * from test order by id desc"
Dim RS As New DataSet
Dim DA As New OleDb.OleDbDataAdapter
DA.SelectCommand = New OleDb.OleDbCommand(s, objconn)
DA.Fill(RS)
第10行的Tname=RS.Tables(0).Rows(9)("Tname")
