Question

From within a finally block, is it possible to tell an exception has been raised?

Answer 1

You could check if ExceptObject or ExceptAddr are assigned.
In the VCL source this is done for exam. in GIFImg.pas or jpeg.pas.

The following code should output

ExceptObject <> nil
ExceptObject = nil

and if you remove the exception then of course

ExceptObject = nil
ExceptObject = nil

  try
    try
      raise Exception.Create('Just an exception');
    finally
      if ExceptObject <> nil then
        WriteLn('ExceptObject <> nil')
      else
        WriteLn('ExceptObject = nil');
    end;
  except

  end;
  if ExceptObject <> nil then
    WriteLn('ExceptObject <> nil')
  else
    WriteLn('ExceptObject = nil');
