How can I run a script when an application quit??

Question

Greetings all,
I'm trying to write a script, which can be triggered automatically (to do some stuff) at the time when a given application quit. I was playing around with this test script, taking "TextEdit" as an example - it just prints a message when TextEdit exits.
==========================================
+*set targetapp to "TextEdit"*+
+*tell application "System Events" to set rr to name of the processes*+
+*--if targetapp is not in rr then*+
+*-- tell application targetapp to activate*+
+*-- tell application "System Events" to set rr to name of the processes*+
+*--end if*+
+*set rr1 to rr*+
+*repeat until rr1 ≠ rr and targetapp is not in rr1*+
+*tell application "System Events" to set rr1 to name of the processes*+
+*do shell script "sleep 1"*+
+*end repeat*+
beep
+*display dialog (targetapp & " is not active anymore !") as string buttons {"OK"} default button 1 with icon 0*+
============================================
Unfortunately, it seems to work if I launch TextEdit using the script itself; it doesn't work with first +*"if - end if"*+ block commented out. Does anyone know how can I achieve this? Any help or suggestion greatly appreciated. Cheers!!

Hi santanu,
I'm sure you can use a variation of this application of mine to do what you want. It monitors all running processes and then reports when one closes.
--initialize previous_processes
global previous_processes
tell application "Finder"
set previous_processes to get the name of every process --use "whose visible is true" to remove the background ones
end tell
--monitoring script
on idle
tell application "Finder"
set current_processes to get the name of every process
end tell
set numberofprocesses to count of items in previous_processes
set counter to 1
repeat while counter is less than (numberofprocesses + 1)
if current_processes does not contain item counter of previous_processes then
display alert item counter of previous_processes & " quit!"
end if
set counter to counter + 1
end repeat
set previous_processes to current_processes
return 1 --runs every second...can be changed
end idle
