    <p>I have an application A that I would like to be able to invoke arbitrary other processes as specified by a user in a configuration file.</p> <p>Batch script B is one such process a user would like to be invoked by A. B sets up some environment variables, shows some messages and invokes a compiler C to do some work.</p> <p>Does Windows provide a standard way for arbitrary processes to be terminated cleanly? Suppose A is run in a console and receives a CTRL+C. Can it pass this on to B and C? Suppose A runs in a window and the user tries to close the window, can it cancel B and C?</p> <p>TerminateProcess is an option, but not a very good one. If A uses TerminateProcess on B, C keeps running. This could cause nasty problems if C is long-running, since we might start another instance of C to operate on the same files while the first instance of C is still secretly at work. In addition, TerminateProcess doesn't result in a clean exit.</p> <p>GenerateConsoleCtrlEvent sounds nice, and might work when everything's running in a console, but the documentation says that you can only send CTRL+C to your own console, and so wouldn't help if A were running in a window.</p> <p>Is there any equivalent to SIGINT on Windows? I would love to find an article like this one: <a href="http://www.cons.org/cracauer/sigint.html" rel="noreferrer">http://www.cons.org/cracauer/sigint.html</a> for Windows.</p>

    1. CO+1 for good question. Funny there have been no answers... I am not aware of a signal-like mechanism in Win32. When I needed to notify child processes I posted a WM_CLOSE message to GUI apps. For console applications I created them by attaching input and output streams to the main application and when I wanted to terminate them I just closed the input stream. As for children of children etc, I relied on my direct children to cleanup their dependencies :).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
