Koneksi VB.Net 2005 dengan data base Access 2003
Untuk membuat koneksi database VB.Net ke Access 2003 kurang lebih kaya gini :
buka jendela coding dan tulis coding berikut :

Imports System.Data.OleDb
Public Class TampilGrid
Dim Conn As OleDbConnection
Dim da As OleDbDataAdapter
Dim ds As DataSet
Sub Koneksi()
     str = "provider=microsoft.jet.oledb.4.0;data source=db1.mdb"
     Conn = New OleDbConnection(str)
              If Conn.State = ConnectionState.Closed Then Conn.Open()
     End Sub

Private Sub TampilGrid_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Koneksi()
da = New OleDbDataAdapter("Select * from barang", Conn)
ds = New DataSet
ds.Clear()
da.Fill(ds, "Barang")
DGV.DataSource = (ds.Tables("Barang")) 'DGV adalah nama grid yang di ubah name nya'
End Sub
End Class

                If Conn.State = ConnectionState.Closed Then Conn.Open()
End Sub
Private Sub TampilGrid_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
