MS Access obtaining Data Source Path

In the code attached, I would like to know how to dynamically specify the Data Source path to which the database is already linked to/

Also, my existing database uses .mdw file which contains list of users and passwords, which are required to log into the database.

For example in this line of code
cnn.Properties("Data Source") = "C:\MDB\Northwind.mdb" << I would like this path to be picked up from the current link.

I would also like to know how to pick up the existing username and password that is currently logged into the database and specify it in the attached code.

For example:
 Set wsDAO = DBEngine.CreateWorkspace("WorkSpace", "Admin", "", dbUseJet) << Where it says Admin, I would like that to be dynamically assigned depending what the current user, as well as the password.

'This sample uses Form level scope for the open DAO database.
'Depending on your application, you may choose Module level.
Private wsDAO As DAO.Workspace
Private dbDAO As DAO.Database

Private Sub Form_Load()
   Dim cnn As ADODB.Connection

  'ADO has the ability to open row-level locking; DAO does not.
  'The following code is used to implement row-level locking in DAO.
  'If the database is opened first in row-level locking in ADO,
  'subsequent attempts to open the database in ADO and DAO will use the same mode.

   Set cnn = New ADODB.Connection
   cnn.Provider = "Microsoft.JET.OLEDB.4.0"
   cnn.Properties("Data Source") = "C:\MDB\Northwind.mdb"
   cnn.Properties("Jet OLEDB:Database Locking Mode") = 1
   cnn.CursorLocation = adUseServer
   cnn.Open

   Set wsDAO = DBEngine.CreateWorkspace("WorkSpace", "Admin", "", dbUseJet)
   Set dbDAO = wsDAO.OpenDatabase("C:\MDB\Northwind.mdb")
   
   'Close the ADODB connection.
   cnn.Close
   Set cnn = Nothing
End Sub
