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) Try connection.Open() oledbAdapter = New OleDbDataAdapter(sql, connection) oledbAdapter.Fill(ds) oledbAdapter.Dispose() connection.Close() 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)) Next Catch ex As Exception MsgBox("Can not open connection ! ") End Try End Sub End Class
connetionString = "Data Source=ServerName;Initial Catalog=DatabaseName;User ID=UserName;Password=Password"
sql = "Your SQL Statement Here"
You have to replace the string with your real time variables.
