Binding ComboBox to MS Access database connection

hi replace your Access database file path in the connection string and give the table name and column name as required.
this is a sample example.

Private Sub FillCombo()
       Try
           Dim fillcon As New OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=path to access file.mdb;")
           Dim asql As String = ("SELECT * FROM Items ORDER BY ItemName")
           Dim da As New OleDbDataAdapter(asql, fillcon)
           Dim ds As New DataSet
           da.Fill(ds)
           ItemNameCombo.ValueMember = "ItemName"
           ItemNameCombo.DataSource = ds.Tables(0)
           ItemNameCombo.SelectedIndex = 0
       Catch ex As Exception
           MsgBox("ERROR : " & ex.Message.ToString)
       End Try
   End Sub
