Subject: LoadLibrary & GetProcAddress Problem

Hello one and all,

I'm new to Ruby and i have been trying to get this piece of code to call
MessageBox but can't. I know I am missing something but I don't know
what it is. Any help with this would be greatly appreciated!

Here is the code so far:

=============================================================================
require 'Win32API'

LoadLibrary = Win32API.new('kernel32','LoadLibrary','P','L')
GetProcAddress = Win32API.new('kernel32','GetProcAddress','LP','L')

Load = LoadLibrary.call('user32.dll')
Proc = GetProcAddress.call(Load,'MessageBox')

Proc.call(0,"Hello World!","MessageBox in Ruby",0)
=============================================================================

I know everything is ok except my "Proc.call". What am I missing?
