Could some one tell how I can safely terminate an application started by 
CreateProcess? I want to kill all the processes started from my application 
before I exit my application. When you kill the process, it may still work, 
say play a movie or song. Based on the help, TerminateProcess is  obviously 
not recommanded. What is alternative?

Thanks,
        Binzhong

If you look in the win32.hlp file for CreateProcess and
examine the LPPROCESS_INFORMATION parameter, you'll see that
that pointer is used to pass back information about the new
process in the form of a PROCESS_INFORMATION structure which
has a dwProcessId member that you can use to accomplish what
you want.

When your application closes, use the win32 API EnumWindows to
enumerate all of the windows. In the callback function for
EnumWindows, use the win32 API GetWindowThreadProcessId and
compare the returned ID to the dwProcessId member of the
PROCESS_INFORMATION structure and if they match then use the
win32 API SendMessage to send a WM_CLOSE message to that
window.

If any of the processes do not have a window, you'll have to
brute force it with TerminateProcess.

Use EnumWindows() and GetWindowThreadProcessId() to find any windows that
belong to the spawned process, and send them all a WM_CLOSE or WM_QUIT
message.
