I tried this when I saw the original email, but couldn't get it to work.
Mapping those funky Windows types is tricky. But anyhow, here is the
(non-working) code:
require 'Win32API'
SendInput = Win32API.new("user32", "SendInput", ['I','P','I'], 'I')
GetLastError = Win32API.new("kernel32", "GetLastError", [], 'L')
INPUT_MOUSE = 0
INPUT_KEYBOARD = 1
INPUT_HARDWARE = 2
KEYEVENTF_EXTENDEDKEY = 0x0001
KEYEVENTF_KEYUP = 0x0002
KEYEVENTF_SCANCODE = 0x0003
# The Left and Right Windows keys
VK_LWIN = 0x5B
VK_RWIN = 0x5C
def send_key(key)
keyboard_input = [INPUT_KEYBOARD, key[0], 0, 0, 0, 0].pack('LCCLLL')
SendInput.call(1, keyboard_input, keyboard_input.size())
end
res = send_key('R')
puts "Got result: #{res}"
puts "GetLastError: #{GetLastError.call}"
__END__
If anyone gets this working, I'd like to hear about it.
