DAO in VB .NET MS ACCESS Database

How to connect Access Database using DAO In VB  .Net

vb .net DAO
vb .net DAO

Data Access Object (DAO)

According to Microsoft Docs , Conversion from DAO TO ADO : Versions of the DAO library prior to 3.6 are not provided or supported in Access.

ODBCDirect workspaces are not supported in Microsoft Access 2013. Use ADO if you want to access external data sources without using the Microsoft Access database engine.
DAO is used with Access databases and is supported through Office 2013. DAO 3.6 is the final version, and it is considered obsolete. These classes work with the other application framework classes to give easy access to Data Access Object (DAO) databases, which use the same database engine as Microsoft Visual Basic and Microsoft Access. The DAO classes can also access a wide variety of databases for which Open Database Connectivity (ODBC) drivers are available. Programs that use DAO databases will have at least a CDaoDatabase object and a CDaoRecordset object.

DAO 360 dll

  • Data Access Object Version 3.60
  • Path : C:\WINDOWS\assembly\GAC\dao\

vb .net Project Design

  • Create new visual basic Project - WinForm

Code

Imports DAO
Public Class Form1
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim DB As DAO.Database
Dim DBE As New DAO.DBEngineDB = DBE.OpenDatabase("ahmed.mdb", Nothing, False, "dbase iv;")
