If the LoadFromFile fail to open a JPEG file, the program will halt and raise a exception !
As a result, how can I control this without halt the program ?

Hi Andrew,

use this one:

  try
    jpeg.LoadFromFile(...);
    result:=true;
  except result:=false end;

Heh? What do you mean?

Do you want to have the exception text? Then do something like this:

  try
    ...
    result:='Everything is fine...';
  except
    if ExceptObject is Exception then
         result:=(ExceptObject as Exception).Message
    else result:='Unknown Exception...';
  end;

Regards, Madshi.
