	// We'll use FindWindowEx this time because it is used to find
	// child windows

		// the edit control

			// the loop, so ignore it.

	/*
	The only drawback of this function is that in order to see what
	was written to Notepad, the user must manually go at bring the
	window to the foreground. While there is a function that can do
	this automatically (SetForegroundWindow()), it won't work because
	the console must be in the foreground in order to, well, RUN!
	
	Note:
	This function works just as if you were to use cout<< or printf()
	meaning in order to start a new line, you must include a '\n' character
	in the text (as shown above). To delete text, use '\b'
