What process do you need to stop?

So what do you need help with, adding a button, responding to a button click, or stopping a process?

i need help about stopping the process the prcess is driving a stepper motor i mean the button must stop all actions while my program sending data to parallel port, just like an emergency "stop button" or "cancel button in install application" thanks

Ok, then you'll need at least one other thread for this. Do the work of communicating with the parallel port in the secondary thread. This will free up the primary thread to handle the UI. See here for the way to gracefully stop a thread.
