From least specific to most...
To "trap" for an error, you use a 'try...on error...end try' block
of code.
try
tell app "Finder" to -- do some stuff
on error errMsg_ number errNum_
return {errNum_, errMsg_}
-- or whatever else
end try
Sorry. I wasn't specific at all. I know about try blocks. My question
was more about how to capture the error and then retry - presumably a
set number of times before finally failing. But then I've just gone
and answered my own question really.
Okay, that's that. But, in your case, when you are copying a file,
what you
probably want to do is to wait until the file is finished before
moving on.
To do that, you don't need the Finder. Use the 'busy status'
property of
the file information record you get from the 'info for' command.
tell app "Finder" -- to do some copying with 'f'
...
repeat until busy status of (get info for f) is false
-- wait, twiddle thumbs
end repeat
OR
repeat while busy status of (get info for f) is true
-- wait, twiddle thumbs
end repeat
Both of those repeat formats work for me, X.3.9. That may work for
your
application as well.
Useful - in that it's sparked a line of thought for why a completely
different (AppleScript) app throws the "Finder is busy" error - but
not so useful here in that the calling app doesn't (call) until the
file is completely written out.
OK. I'll just script the Finder for this I think.
