Re: Process.Start & Process.Kill

As has been mentioned, process is probably being recycled.

You're really at the mercy of the program you're executing as to whether
it implements a singleton of sorts and recycles an already running
process.  Without performing some automation on an existing process,
there's not much you can do using the Process class.  You can subscribe to
the Exited event and you'll be notified if the process you spawned was
terminated before you expected it to be (it's a good idea to subscribe to
this event in general, as the user can terminate the process you spawn and
the only other way to handle it is to catch the exception).

In the case of Acrobat Reader, you can probably do something with DDE to
get it to load a PDF file instead of executing a PDF file.  That's
essentially what the shell does...
