Create single instance applications linked to associated file types. When the associated file is double clicked it will be handled by a single instance of your application. This lets your application act like Media Player rather than Notepad. Each time you double click a media file Media Player does not open a new window but re-uses the existing one. This is normally difficult to achieve in Visual Basic but the OneOnly control makes it simple.
