Yes: I've found it useful to wrap AutoIt#Send to allow multiple sending multiple keystrokes with waiting periods between each "bunch" of keystrokes. WinModule::AutoIt = = WIN32OLE.new( "AutoItX3.Control" ) # send_keys( "cc", 1.5, "kty" ) sends "cc", sleeps 1.5 seconds, sends "kty" def send_keys( *args ) args = args[ 0 ] if args.size == 1 && args[ 0 ].kind_of?( Array ) args.each do | arg | case arg when String then AutoIt.Send( arg ) when Numeric then if ! ( defined?( Complex ) && arg.kind_of?( Complex ) ) then sleep arg end end end end Other examples are here http://gist.github.com/368632 which has some stuff which doesn't need Autoit, and other stuff for which AutoIt is not needed but for which *I* need AutoIt because I have not yet found out how to do it without AutoIt. For example this MsgBox code works in JRuby 1.4 and Ruby 1.8.6 but (it seems) not in Ruby 1.9.1 (at least not for me!): User32_MsgBox = User32[ 'MessageBoxA', 'ILSSI' ] result, = User32_MsgBox.call(0, text, title, buttons + icon + modality) So if anyone knows how to use "dl" and Win32API.new( 'user32', 'SendInput', 'IPI', 'I' ) to send keystrokes (or can pop up a MsgBox in Ruby 1.9.1) I'd be very interested to see how. > It's also handy to learn about the Windows message queue and sending > commands there.

Thanks.

Sorry: in case anyone is confused by that User32[...], the "proper" code is: # note that Win32API is deprecated after Ruby 1.9.1 - use dl directly instead require 'dl' User32 = DL.dlopen( 'user32' ) # works in JRuby 1.8 and MRI Ruby 1.8.6, but not in 1.9.1; User32_MsgBox = User32[ 'MessageBoxA', 'ILSSI' ] # User32_MsgBox.call returns an array: # [return_value, [0, text, title, buttons + icon + modality]] # we only want the return value, hence "result, =" result, = User32_MsgBox.call(0, text, title, buttons + icon + modality) puts result But I'd still be interested if anyone can get this to work in Ruby 1.9.1. I get this error message from User32_MsgBox = User32[ 'MessageBoxA', 'ILSSI' ] in '[]': wrong number of arguments(2 for 1) (Argument Error)

You could use the win32-api gem: --------------------------------------- require "win32/api" MessageBox = Win32::API.new("MessageBox", 'LPPI', 'I', "user32") MessageBox.call(0, "Text here", "title here", 0) --------------------------------------- The constants for style and return value remain the same. The above code will get the ASCII function, if you want the UTF-16 + extra-NUL-w-function use this: --------------------------------------- MessageBox = Win32::API.new("MessageBoxW", 'LPPI', 'I', "user32") title = "Title\0".encode("UTF-16LE") text = "Text with ä\0".encode("UTF-16LE") MessageBox.call(0, text, title, 0) ------------------------------------- If I ommit the trailing NUL, I get some strange Chinese characters displayed.
