I'd like to save the state of my machine before shutdown (for machines that do not support hibernate). Essentially, I'm trying to mimic the Windows Hibernate feature. When the machine its turned back on, it looks exactly like it did previous to being shut down. Any ideas on using managed code to perform this task? Currently using/co...
I've got a program that's having some trouble during shutdown, raising exceptions that I can't trace back to their source. It appears to be timing-related and non-deterministic. This is occurring after all shared resources have been released, and since it's shutdown, memory leaks are not an issue, so that makes me wonder if there's any...
Under POSIX OS there is signal API that allows to send a signal to process to shut it down with kill and you can catch it with sigaction and do what you need; However, Win32 is not POSIX system, so: How can I handle shutdown events that may come, for example from "End Process" in "Task manager"? What is the standard API for sending sh...
I have a small program which simply reads a diary text file and displays it in a memo - thats it - no buttons you double click on the form to shut it down if you want it to disappear.

Unlike Windows Vista, when Windows XP is shutting down - it doesn't tell you which program is requesting not to be shutdown. This leaves Windows still running and not telling you what program is preventing shutdown. As I understand it, Windows sends WM_QUERYENDSESSION to all applications. If any of the applications return 0 to the funct...
