Thanks, although I'm 99% sure I've also tried it without CREATE_NEW_CONSOLE (with a process that should just die if sent CTRL- C, so it was monitorable via Task Manager) and it still didn't work. I'm going to try taking a different approach by using a GUI Automation tool like WATSUP [1] or pywinauto[2] next. > Maybe you have better luck on a Windows programming group, asking how to > send a Ctrl-C event (or a SIGINT signal) to another process attached to a > different console. >From what I've found via Google [3], Windows has no real concept of signals, and no equivalent to SIGINT.
