Subject: windows messagebox example(s)

This is probably documented somewhere, but I thought ruby win32 
programmers on the list may find this of use.

require 'Win32API'

def message_box
   # Create a Windows MessageBox.
   # 0 = 'OK' Button
   # 1 = 'OK' 'Cancel' Buttons
   # 2 = 'Abort' 'Retry' 'Ignore' Buttons
   # 3 = 'Yes' 'No' 'Cancel' Buttons
   # 4 = 'Yes' 'No' Buttons
   # 5 = 'Retry' 'Cancel' Buttons
   # 6 = 'Cancel' 'Try Again' 'Continue'
   #######################
   # 16 = 'OK' Button with 'Error' Symbol
   # ... SEE ABOVE EXAMPLES
   # 22 = 'Cancel' 'Try Again' 'Continue' Buttons with 'Error'
   #######################################
   # 32 = 'OK' Button with 'Question' Symbol
   # ... SEE ABOVE EXAMPLES
   # 38 = 'Cancel' 'Try Again' 'Continue' Buttons with 'Question'
   #########################################
   # 48 = 'OK' Button with 'Warning' Symbol
   # ... SEE ABOVE EXAMPLES
   # 54 = 'Cancel' 'Try Again' 'Continue' Buttons with 'Warning'
   ########################################
   # 64 = 'OK' Button with 'Info' Symbol
   # ... SEE ABOVE EXAMPLES
   # 70 = 'Cancel' 'Try Again' 'Continue' Buttons with 'Info'
   ######################################
   mb = Win32API.new("user32", "MessageBox", ['i','p','p','i'], 'i')
   mb.call(0, 'message', "title", 0)
end

x = message_box
