I want my main ahk file, to check for a certain window, and if that window exists, to launch a second ahk file (if and only if it is not already running).

having trouble doing this that part that is in bold font.

I can detect the window with a timer:

Code:
settimer, checkwindow, 500
return

checkwindow:
if winexist, my window
{
if [detect if "mysecondahk" is running or not]
;if its not running,
run mysecondahk.ahk
}
;else
return

The reason I'm having trouble detecting whether 'mysecondahk' is running or not, is because I'm not able to capture its ID and title and etc using "windowspy".

help! thanks...

Why not use #SingleInstance Ignore?

well, that seems wasteful doesnt it? I mean in terms of a hit on performance. Wouldnt the first script continually (every 1/2 second) try to launch the second script even when it doesnt have to?

A working example. mysecondahk.ahk will run and exit along with Calculator
Code:
#Persistent
DetectHiddenWindows, On
SetTitleMatchMode, 2
SetTimer, CheckWindow, 500
Return

CheckWindow:
IfWinExist, Calculator
 {
  IfWinNotExist, mysecondahk.ahk ahk_class AutoHotkey
    Run mysecondahk.ahk
 }
Else PostMessage,0x111,65405,0,,% "ahk_id" WinExist( "mysecondahk.ahk ahk_class AutoHotkey")
Return


Code:
;mysecondahk.ahk
Gui +LastFound

#SingleInstance Ignore wrote:
The word IGNORE skips the dialog box and leaves the old instance running. In other words, attempts to launch an already-running script are ignored.


Seems to me like that's what you'd be looking for. If script 2 isn't running, script 1 can run it, if it is running the script 1's attempt to run it will be ignored.
