Recently I stumbled into a situation where an unhandled exception

IMO such a dialog, with severe consequences, should not use
standard OK/Cancel buttons, and also should not associate commonly
used shortcuts with the buttons. Instead more intuitive
Kill/Continue buttons should be used.
In typical situations the Escape key is associated with Cancel,
meaning to abort or undo a wrong action. In the case of an
exception this should mean to cancel the *action* (and continue),
not to kill the *application*.
I think that this is a good proposal.
The QuestionDLG can be used for this, I assume.
The MessageBox is used, because it can be handled completely
by the widgetset and therefore works even if the heap got corrupted.
It is a matter of priority. Show some information to help fixing the
bug, or help the user to ignore the bug.
For a fact, the user usually cannot make this decision :-)
We could:
Add a flag to Application so that the programmer can decide what to
show (MessageBox/QuestionDlg).
And/Or: add an event to let the programmer show its own dialog.
This latter exists already, no ? OnShowException ?
Michael.
