process controll, please advise.

hi all,

i have a independant process running on machine which was made by some one else, it natively live in my system tray although has a windows form interface.

what i want to be able to maximize the process/application to full screen from wihtin inside my program.

my problem i dont how you would do this. not that i cant just do:

process k = new process()

because i want to be able to use the currently running instance, if i were to make a new instance the program would jsut say its already runnng.

thanks
