From: "Jethrow .." Date: 2010-10-20T03:27:42+09:00 Subject: Re: DL Library - Ruby 1.9.2 - Windows Thank you for the response John. I assume you mean something like this: require 'Win32API' msgbox = Win32API.new("user32", "MessageBox", ['i','p','p','i'], 'i') msgbox.call(0, 'message', "title", 0) I was looking for an example using the DL Library. I was under the impression this library was reimplemented in version 1.9.2: "About Ruby 1.9.2 ... •dl is reimplemented on top of libffi." -- Posted via http://www.ruby-forum.com/.
