Thanks

require 'win32ole'
network=WIN32OLE.new("Wscript.Network")
puts network.username

#or
puts ENV['username']
#for win95/98 use
puts ENV['userid']

#or (stolen from www.,rubytips.org)
require 'Win32API'
name = " " * 128
size = "128"
Win32API.new('advapi32','GetUserName',['P','P'],'I').call(name,size)
puts name.unpack("A*")

Take your pick.

Regards,

Siep

NT/2K/2K3/Vista systems have a environment variable for interactive
users:

irb(main):001:0> ENV['USERNAME']
=> "Luis"

So you only need to asign ENV['USERNAME'] and will get the current
username.

If your process is not an interactive one (ala, a Windows service)
then this variable will be nil or the special account used for it
(LocalService).

HTH,

This is the one function of the 'etc' library that works on Windows:

require 'etc'
puts Etc.getlogin

Or, you can use the sys-admin library, which provides much more
functionality on Windows:

gem install sys-admin
require 'sys/admin'

puts Sys::Admin.get_login
