How to Connect Access Database to vb.net
- Step 1: Create MS Access Database
n creating MS access database name it as “firstDB” then create a table named “tblstudent” and this looks like as shown below.
- Step 2: Create a VB.Net Application
Create Visual Basic Application then Add a button this will look like as shown below.
- Step 3: Declare con for “oledbconnection”
In this step, we will now add functionality to our application. To do this, double click our form and the following code below Public class:
- Step 4: Add code to Test Connection Button

- Step 5: Add code under the connection string

Here’s all the code to connect the access database to vb.net with an explanation.
Dim con As New OleDb.OleDbConnection
The code above simply Initializes a new instance of the OleDbConnection class.
conn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & Application.StartupPath & "\firstDB.accdb"
The added line of code, we simply use the two technologies called: Provider and Data Source.
Without this, we cannot connect to our database because this is where we specify what type of database provider and the Data source of our database used for this connection.
And we use also the “Application.StartupPath” where it is the path for the executable file that has started the application, and this location also where we are going to put our database file.
conn.ConnectionString = “Provider=Microsoft.ACE.OLEDB.12.0;Data Source=” & Application.StartupPath & “\firstDB.accdb”
Under the code above, add another set of code:
'opens the connection
If conn.State = ConnectionState.Open Then
MsgBox("MS Database Connected!")
Catch ex As Exception
'close the connection
The newly added sets of code will simply check if the connection between Visual Basic.Net and MS Access database has been established successfully.
