- Step 2: Create a VB.Net Application

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.
