vb.net and sql connection query

I am attempting to create a sql connection query into an access database.  This works fine if i give it an absolute path, i am trying to use the datadirectory to call it.  How do i set the appdomain to tell datadirectory to use the applicationdata directory?  I am trying to use the below, but it errors out with "The DataDirectory substitute is not a string."  Basically i have a folder in applicationdata called BMW Maintenance and in that folder is my DB.  I need to connect to it.

AppDomain.CurrentDomain.SetData("DataDirectory", Environment.SpecialFolder.LocalApplicationData)
        Dim con11 As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\BMW Maintenance\BMWMaintenance.accdb")

Try replacing first line with below one.

AppDomain.CurrentDomain.SetData("DataDirectory", Convert.ToString(Environment.SpecialFolder.LocalApplicationData))

The error is correct, that's a number (28), try:
AppDomain.CurrentDomain.SetData("DataDirectory", Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData))
