我发现了这个：

I found this:

Dim ConnectionString As String

       ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=C:\;Extended Properties=dBase IV"
       Dim dBaseConnection As New System.Data.OleDb.OleDbConnection(ConnectionString)
       dBaseConnection.Open()

       Dim dBaseCommand As New System.Data.OleDb.OleDbCommand("SELECT * FROM dbase", dBaseConnection)
       Dim dBaseDataReader As System.Data.OleDb.OleDbDataReader = dBaseCommand.ExecuteReader(CommandBehavior.SequentialAccess)

       While dBaseDataReader.Read
           TextBox1.Text = (dBaseDataReader("Column1").ToString)
           TextBox2.Text = (dBaseDataReader("Column2").ToString)
           TextBox3.Text = (dBaseDataReader("Column3").ToString)
       End While

       dBaseConnection.Close()

但是我们只显示最后一行...如果有人知道怎么做才能回到第一行或下一行，最后一行...

but we show only the last line ... if anyone knows how I could do to get back to the first or next row, the last ...

如果有人知道我是怎么做的？
