Hi,
sometime the following line produces an exception:
((CMessageDialo g*)vec->at(0))->EndDialog(1) ;
Now I want to catch this Exception, tried it with c++ and mfc exception
handling, like:
C++ in MFC
try
{
((CMessageDialo g*)vec->at(0))->EndDialog(1) ;
}
catch(CExceptio n *e)
{
}
---------------------------------------------------------
MFC Makro
TRY
{
((CMessageDialo g*)vec->at(0))->EndDialog(1) ;
}
CATCH(CNotSuppo rtedException, pEx)
{
}
END_CATCH
The Debugger still shows exceptions but never enters the chatch area.....
Can anyone please help me, why the exception is not catched?
Thank you

The question would be: What of this line
produces the exception?
From what I see it could either be 'at()'
or 'EndDialog()'. If it's the formerm a
'catch(const std::exception& )' would catch
it.

Thank you

Hi,
the 0. position is a pointer to an Dialog. I think two threads try to acces
the dialog... So it is an Accessexception , the id is 0xc0000005.
But the exception is not chaught.
in german:
Hi,
Du sprichst deutsch oder? :=)
Also ich an der 0.ten Position befindet sich ein Zeiger auf einen Dialog...
Die Exception ist eine Zugriffsexcepti on weil 2 Threads auf den Dialog
zugreifen. Der Dialog sollte synchronisiert und gelockt sein..
Aber ich kann den Exception nciht abfangen...
In MFC sind doch alle Exception von CException abgeleitet, oder?

Access violations shouldn't be caught,
they should be fixed. They represent
an error in your program. You don't
want to hide that error. You want it
to be seen so it gets fixed.
That said, if you really want to catch
it, Structured Exception Handling is
what you need.

Gut. Und wenn das getan wurde, gibt es
hoffentlich keine AV mehr. Warum willst
Du sie fangen?
Aber ich kann den Exception nciht abfangen...
Suche SEH in der MSDN Lib. Oder laß es
lieber, und behebe den Fehler.
In MFC sind doch alle Exception von CException abgeleitet, oder?
Ich habe MFC nie benutzt.

Hi all
I noticed something interesting while testing some RAII concepts
ported from C++ in Python. I haven't managed to find any information
about it on the web, hence this post.
The problem is that when an exception is raised, the destruction of
locals appears to be deferred to program exit. Am I missing
something? Is this behaviour by design? If so, is there any reason
for it? The only rationale I can think of is to speed up...

Is there a tool that can determine all the exceptions that can be raised

I've read that it is best not to use exceptions willy-nilly for stupid purposes as they can be a major performance hit if they are thrown. But is it a performance hit to use a try..catch..finally block, just in case there might be an exception? i.e. is it ok performance-wise to pepper pieces of code with try..catch..finally blocks that must be robust, in order that cleanup can be done correctly should there be an exception?

I had a long and heated discussion with other developers on my team on when
it makes sense to throw an exception and when to use an alternate solution.
The .NET documentation recommends that an exception should be thrown only in
exceptional situations. It turned out that each of my colleagues had their
own interpretation about what an "exceptional situation" may actually be.
First of all, myself I’m against using exceptions extensively,...

Chapter 3: What are the most common Exceptions and what do they mean?
As we saw in the last chapter, there isn't only the standard Exception, but you also get special exceptions like NullPointerException or ArrayIndexOutOfBoundsException. All of these extend the basic class Exception.
In general, you can sort Exceptions into two groups: Checked and unchecked Exceptions. Checked Exceptions are checked by the compiler at compilation time. Most...
