app path problem

hi
I have my database inside a folder called MyDatabase;
i have my component inside a folder called MyComponent;
my projects and those two folders are together;
My problem is: how to write the connectionstring, inside my component, to get the right path to the database?
now its like this:

cn.ConnectionString = "provider=microsoft.jet.oledb.4.0; data source =" & App.Path & "\..\MyDatabase/db.mdb"

but that simply doesnt work

How can i make it work?
thanks in advance
