How to close another script

[Phenom 0]

Let's say in my script I start another script like this:

ShellExecute("foo.au3")

Then let's say later on I want to close this script. What's the code to do that?

[Mison 1]

$pid = Run (@AutoItExe&" foo.au3")
Sleep(3000)
ProcessClose($pid)

[Phenom 0]

$pid = Run (@AutoItExe&" foo.au3")
Sleep(3000)
ProcessClose($pid)

That works, but the icon stays in the taskbar. Is there a way to make it go away without having to use the mouse?

Try searching the forums on System Tray Refresh.

Put #NoTrayIcon in the beginning of your script
