Yonatan of yonatan_avraham at hotmail.com humbly asked:

I’m trying to do some WMI stuff with Ruby. I found this
simple example somewhere. It works – until the program
exists that is.
Then Windows pops up a “ruby.exe - Application Error” message
box due to inappropriate memory access.

require ‘win32ole’

mgmt = WIN32OLE.connect(‘winmgmts:\\.’)
mgmt.InstancesOf(“win32_process”).each{ |proc|
puts proc.name
}
pause

Does anyone know how to solve the problem? I’m running “ruby 1.8.0
(2003-08-04) [i386-mswin32]” on Windows 2000.
^^^^^^^^^^^^

I cannot solve it but I can compare it w mine.

c:\family\ruby>ver
Microsoft Windows XP [Version 5.1.2600]
^^^^^^^^^^

…I just installed Ruby 1.8 on an Windows XP box and the WMI example
works
fine. I then installed it on another Windows 2000 box and the WMI example
crashes. Any ideas?

fwiw.

Botp,

After reproducing the crash on both SP3 and SP4, I realized that the
likely difference was that you’re using Ruby 1.8.1 and I’m using Ruby
1.8.0. I just upgraded to Ruby 1.8.1 and confirmed that the example
exits without the crash! Well, I wonder what the root cause was?

Cheers!
