im trying to monitor a process, if this process is closed then i want to
write a time and date to a logfile...

i dont know how to do it but it should be as simple as this...
(improper)

loop {
if process.exist('notepad.exe') then
   puts 'notepad exist'

  else
      my_file = File.new("c:\log.txt", APPEND)
      my_file.puts "here is the time add date, notepad has been killed"
end

}

pids =
ProcTable.ps{ |s|
   pids.push(s.pid) if s.cmdline =~ /calc/

}

How about this:

calc_is_running = ProcTable.ps.any? {|pinfo| pinfo.cmdline =~ /calc/ }
# returns true or false

or if you need the pid of the process later on:

calc_processes = ProcTable.ps.select {|pinfo| pinfo.cmdline =~ /calc/ }
# returns an array of matching processes

if calc_processes.empty? .... else ...

hth,
