Why use _SendMessage() to send keystrokes instead of send(),controlsend() or dll call? Edited February 1, 2008 by cameronsdad

Why use _SendMessage() to send keystrokes instead of send(),controlsend() or dll call?

Well because it would send it directly to the window...

How would you use a dll call for sending keys?
