That is exactly what you need to use.  Pass the returned process handle (not
the thread handle) to WaitForSingleObject().  When the process terminates,
its handle will be signalled, thus releasing WaitForSingleObject() from its
waiting.  If you are doing this in the context of the main thread, and you
have an GUI available, then you should call WaitForSingleObject() in a loop
so that you can call Application->ProcessMessages() periodically to keep the
GUI responsive.

No.  If CreateProcess() succeeds, then they will contains valid values.
Make sure that you pass the returned handles to CloseHandle() when you are
done with them.
