Can't connect to server Visual Basic - Smart Device Application - Visual Studio 2008

I'm trying to connect to a database and am using the emulator (windows mobile 5 r2) could someone tell me what i'm doing wrong? I've also tried using the connection string in the properties of the datasource..
"Data Source=C:\Users \Adam\Documents \Visual Studio 2008\Projects\i nventoryProgram \inventoryProgr am\invDB.sdf"

Dim conn = New SqlCeConnection("Data Source = invDB.sdf")
        Try
            conn.Open()

        Catch ex As SqlCeException
            MsgBox(ex.Message)

        End Try

Forgot to write that the error was that the database file could not be found.
Thanks.
