Visual Basic 2015 – Create new OleDB Connection

I just installed the new Microsoft Visual Basic 2015. I want to build a database data entry using Visual Basic 2015. Here I want to show you how to create a new database connection on Visual Basic 2015. I use MS Access as the back end database and will be connected using OleDB connection.

The form design

Its a simple form with one button to execute or open the database connection. We can expand this later.


The Code

Public Class Form1
    Dim provider As String
    Dim dataFile As String
    Dim connString As String
    Dim sql As String

    Public myconnection As OleDbConnection = New OleDbConnection
    Public dr As OleDbDataReader

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        provider = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source ="
        dataFile = "E:\Solo_Drilling_BE.accdb"
        connString = provider & dataFile
        myconnection.ConnectionString = connString
    End Sub

The code inside Connect button

Private Sub btn_ConnectDatabase_Click(sender As Object, e As EventArgs) Handles btn_ConnectDatabase.Click
    End Sub
