I have just discovered a nice feature in Windows Script Host; which is the SendKeys method in the WScript.Shell class.
Using this method to send a stream of key strokes to another application would allow for remote automation or (for example) creating application tutorials.
Cut the following code, paste in a text file and give it .vbs extension, double click the file to run it and watch J
Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.AppActivate "Untitled - Notepad"
