[Lazarus] Exception dialog

[Samuel Herzog]

Oh, good point to discuss about the use of exceptions.

I use exceptions only for really "unexpected" things.
That a user will sometimes input wrong data must be expected by a programmer so
I do not treat this as an exception.

With unexpected things I mean all the things that are outside my code.
e.g.
  try
    FExcel := GetActiveOleObject('Excel.Application');
  except
     //do something 
  end;

Betreff: [Lazarus] Exception dialog

Hello,

Is there a reason why the default exception dialog has a cancel 
button to kill the application ?

We often use an exception to signal wrong entry of data or so, 
because it stops all further processing.

If the user then uses the cancel button, the program is simply 
ended, which is not what we (or better: the users) want.
And I imagine many others use this technique.

I have overridden the OnException handler of TApplication, 
so it's no longer a problem, but I was curious as to why this
is done like this by default ?

Michael.
