Is this in an application you're writing or are you trying to modify an existing one?

You'd have to use another app to change this app's name. You can't write to an open file, and if the app is running it's open, so it can't write to itself (the operating system prevents it). Developing self-modifying apps is a whole 'nother world. (A very scary and dangerous one.)
