Re: Prevent Canceling

So, is there anyway to prevent users from canceling a running script? (I used Hypercard or Prefab Plaer as workarounds in OS 9, but can't use them in OS 10.

Except if you using a faceless app, I think you cannot prevent the user from interrupting a script with an error number -128, and the error can happen just after (or sometimes, during) any instruction, so you have to handle explicitly the error everywhere, something certainly not simple.

try
-- do the normal thing
-- have all error traps explicitly forward number -128 errors
-- with lines like: on error s number n, if n = -128 then error s number n
on error number -128
-- handle "user canceled": restart everything from scratch, display insults, etc
end
