connecting to ms sql 2017 server using Microsoft.Jet.OLEDB.4.0

I have got an old application developed in Vb.net. It uses MS Access database. But now I need to use MS SQL 2017 server in place of access database.

Private m_ConnString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" 'testdat.mdb"

how to change the above connection string to use MS SQL 2017 server with the application.
