Properties of an application's windows are controllable by the operating system or the application itself. Allowing a different application access to the window is, generally speaking, a violation of process separation. That said, you might look into SIMBL. It allows you to inject code into a running process. Not as a separate process, but it is possible to modify an already running process. Hope that helps. - Josh
