Sending keystrokes to a non active window?

[Eaxo]

I have done it before but cant now because i cant remember the code for it

For ex.

I want to write Hello World in a non active notepad window

I tryed to use this code but no success

If winwaitnonactive ("Untitled") then
 send ("Hello{space}World{!}")
endif

I took this from the help file:

ControlSend("Untitled", "", "Edit1", "This is a line of text in the notepad window")
