You can do it either way.
There's a coercion in OSA Menu (thank you, Leonard) that treats compiled
scripts there as if they were applications. The result of
path to me
is the path name of the script (as alias, or else specify 'as string').
whereas the path name of a compiled script running from an application is
the application's file itself. I've just tested - the result of (path to me)
in an embedded AppleScript in a OneClick button is the path name of the
frontmost application, whatever it is. So:
AppleScript
set p to ((path to me) as string)
set {ods, AppleScript's text item delimiters} to {AppleScript's text
item delimiters, {":"}}
set ap to last text item of p
set AppleScript's text item delimiters to ods
if ap = "NameOfFrontProcess" then -- put real app's name here
set returnHow to "Send to OC"
else
set returnHow to "OSA, so dialog"
end if
(* --or if it works better for you:
if ap = "NameOfThisScript" then -- put real script name here
set returnHow to "OSA, so dialog"
else
set returnHow to "Send to OC"
end if *)
try
--do your stuff here
on error errMsg
if returnHow = "OSA, so dialog" then
display dialog errMsg
else
return errMsg
end if
end try
End AppleScript
