data set& data adapter

Datasets store a copy of data from the database tables
DataAdapters are used to link Databases with DataSets.

sample
Imports System.Data.SqlClient
Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim connetionString As String
        Dim connection As SqlConnection
        Dim adapter As SqlDataAdapter
        Dim ds As New DataSet
        Dim i As Integer
connetionString = "Data Source=ServerName;Initial Catalog=DatabaseName;User ID=UserName;Password=Password"
        connection = New SqlConnection(connetionString)
        Try
            connection.Open()
            adapter = New SqlDataAdapter("Your SQL Statement Here", connection)
            adapter.Fill(ds)
            connection.Close()
            For i = 0 To ds.Tables(0).Rows.Count - 1
                MsgBox(ds.Tables(0).Rows(i).Item(1))
            Next
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try
    End Sub
End Class
