Answer 1

I had the same issue trying to specify the relative file path for a database connected to a Windows Forms application. I was able to resolve the issue by following the directions for adding a data source to Windows Forms from Microsoft (e.g., for connecting an Access database).

By using this method, Visual Studio will set the relative file paths to your database for you instead of trying to set it manually. If your database is external to your application, it will create a copy of the database and add it to your application in the proper location. Although you can manually alter you connection string in App.config and/or Settings.settings or within one of your scripts, I've found this method to be error prone. Instead, I've found it best to follow the Microsoft instructions, in general.
