How to connect ms access with using OLEDB

The last time, I showed you how to connect ms access and using ODBC. This time we will use OLEDB to connect the two.

The procedure is similar, so you may want to check this for a more complete tutorial.

I supposed you still have the files from the previous tutorial. So I’m going straight to the point.

What needs to be changed is the connection string and the name space.

The namespace this time is:


The connection string will be:

Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:UsersWernDocumentsDatabase1.accdb;

Remember to change the data source to the actual path where your database is. Followed by the filename of your database. You can use either .mdb or .accdb for this.

Finally, change all the odbc that you see to oledb.

The whole of your code in your parent class will look something like this:

Imports System.Data.OleDb
Public Class Class1
    Dim con As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:UsersWernDocumentsDatabase1.accdb;")
    Dim cmd As New OleDbCommand
    Public neym As String
    Public Sub New()
        cmd.Connection = con
        cmd.CommandText = "SELECT * FROM table1"
    End Sub
    Public Sub creates()
        cmd.CommandText = "INSERT INTO table1(Neyms) VALUES('" + neym + "')"
    End Sub
End Class

That’s it, don’t forget to declare an object of the parent class that you created on your main form:

dim parent as new class1

Where class1 is the name of the class, and parent is the object name that you want. You can change it to whichever you want. But the class name always depends to what class name you have inputted a while ago.
