Send Win+sapce key, WINDOWS, SPACEBAR

Keyboard code partial turn from: http://www.cnblogs.com/cpcpc/archive/2011/02/22/2123055.html

Because like to use CTRL + SPACEBAR to switch the input method, in the WIN8 is not accustomed to, so wrote a small program, when you press CTRL + SPACEBAR to send win+ space bar.

First use the global shortcut key, monitor CTRL + Space input, and then send the win+ space bar.
