cocoa/obj c

I have an pointer to NSRunningApplication. Is there a way I can resize the application window? Let's say I want to maximize it, how can I do that? I checked the documentation and there's nothing there to do this. I can terminate it, force terminate it, so there's got to be a way to resize it...
thanks

Nah, it's more of a 'modern' programming thing now. It definitely leans more toward EE and churning out codemonkeys.
