Hi!

I know to open a instance of CMD in windows and get the return code

puts %x[Tasklist /v | Find “%tmp:~0,30%” >NUL]
response = $?.exitstatus

that works.

But now i need to open a hide instance of the CMD, i only know to do it
eith Win32ole module, and the funcion “exitstatus” sends me an error…
i don’t know why…

Please help to get the exit code of that instance, or another way to
open (and get exitcode) of a hide instance.


require 'win32ole'
shell = WIN32OLE.new('Shell.Application')

shell.ShellExecute('CMD', '/K Tasklist /v | Find "%tmp:~0,30%" >NUL',
'', '', 0)
response = $?.exitstatus
  if response == 0
    puts "hola"
    end

undefined method `exitstatus’ for nil:NilClass
