How to Dataset with OLEDB Data Source

The DataSet contains the copy of the data we requested through the SQL statement. We can use Dataset in combination with OleDbDataAdapter class . The OleDbDataAdapter object allows us to populate Data Tables in a DataSet. We can use Fill method in the OleDbDataAdapter for populating data in a Dataset.

Imports System.Data.OleDb
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 OleDbConnection
        Dim oledbAdapter As OleDbDataAdapter
        Dim ds As New DataSet
        Dim sql As String
        Dim i As Integer

        connetionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Your mdb filename;"
        sql = "Your SQL Statement Here"

        connection = New OleDbConnection(connetionString)
            oledbAdapter = New OleDbDataAdapter(sql, connection)

            For i = 0 To ds.Tables(0).Rows.Count - 1
                MsgBox(ds.Tables(0).Rows(i).Item(0) & "  --  " & ds.Tables(0).Rows(i).Item(1))
        Catch ex As Exception
            MsgBox("Can not open connection ! ")
        End Try
    End Sub
End Class

connetionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Your mdb filename;"
sql = "Your SQL Statement Here"

You have to replace the string with your real time variables. (C) 2016    Founded by raps mk
