Process Group question
I have an MFC based (gui) app, that creates anonymous pipes to a console app that it communicates with. I have to be able to kill off the console app from the MFC app if the console app gets hung. This works fine if I communicate directly with the console app, because I can call TerminateProcess() to kill it off if need be. However, I need to implement support for a console app that has a pre-processing front-end app. Basically, this pre-processing app parses through the work load, and determines the proper console app to start up to process the work load. So I need to do this: use CreateProcess() to execute the pre-processing app (which is a console app as well), and that process in turn executes another process. HOWEVER, if I kill off the pre-processing app, it leaves the workload-processing console app hanging around in the background. Is there a way to kill off the pre-processing app along with any child processes? The concept I'm talking about here is a process group. I tried using CreateProcess() with the CREATE_NEW_PROCESS_GROUP flag, and then using GenerateConsoleCtrlEvent() to send a CTRL_BREAK event to the pre-processing app, but it doesn't work for me. Any ideas?

Isn't that basically the same as you asked in https://www.experts-exchange.com/jsp/qShow.jsp?ta=mfc&qid=10203214 ?

To JKR:
Yes, I did ask the same question before. I'm not sure why it says 'accepted answer', because I don't remember accepting it, and it certainly didn't ever work for me.
To NickRepin:
I was thinking along those lines. This sounds like a reasonable solution. I'll try implementing it tomorrow morning and let you know. Thanks!

I tested it before I posted the answer here.

One other problem I'm having Nick: Everything works fine with the process group, but when I call AllocConsole(), it shows the console window. Can I have it be hidden some how? Thanks!
