Hi,

Is that correct behavior? When calling Halt() somewhere inside a try..finally block, it _doesn't_ execute the finally code.

In fpGUI I used Halt() to terminate the event loop and exit a application. I then noticed that NO cleanup code gets executed after that call. Not objects get freed via destructors etc... Since I noticed this, I implemented a more graceful termination process, but Halt() is really harsh! :-)

This is by design.

Halt finalizes the units and then exits.

Yeah, I always used to use something like:

var
  haltApp: boolean;
begin
haltApp := false;
try
  //some code that does something
  if (some_condition) then
  begin
    haltApp := true;
    exit;
  end;
  //some other code
finally
  //cleanup code
  if (haltApp) then Halt(halt_condition_code); // one could argue this
should be outside of the finally,
                                                                     //
but if it were it would not always be executed as
                                                                     //
desired - especially if an exception was raised.
end;

Thanks. I'll make a mental note to stay away from it. :)
