Hi all.
Handling files is an extremely frequent task in programming, so most
programming languages have an abstraction of the basic files offered by
the underlying operating system. This is indeed also true for our language
of choice, Python. Its file type allows some extraordinary convenient
access like:
for line in open("blah"):
handle_line(line)

Hi,
I am an absolute newbie to Exception Handling, and I am trying to
retrofit exception handling to a LOT of C++ code that I've written
earlier. I am just looking for a bare-bones, low-tech exception
handling mechanism which will allow me to pass character information
about an error and its location from lower-level classes.
Can you please critique the following exception handling mechanism in
terms of my requirements ?

Some time ago, I remember reading a discussion about the strengths and
weaknesses of exception handling. One of the weaknesses that was put
forward was that exception handling is inefficient (in the way of CPU
usage), compared to the "normal" practise returning values.
How true is this? Will using using exception handling, in general, be
much less efficient than returning values, or less efficient at all?
Just curious...

When Exception handling disabled compiler still spits out "C++ exception
handler used." Why is that?
Why does it ask for "Specify /EHsc"?
Thanks!
c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\xstring(1453)
: warning C4530: C++ exception handler used, but unwind semantics are not
enabled. Specify /EHsc

I'm confused about structured error handling. The following piece of
code is a simplification of a class library I'm working on. It works,
and it does what I want, but I'm still not convinced that I have been
doing it right. I think I overdo it. Please have a look:
--
using System;
using System.IO;

While writing some code, I realized I had never developed a consistent
pattern for checking errors from a method. I have two styles I jump
back and forth between, but I'm wondering which is better.
Scenario:
* In method that returns success/fail
* Call method that also returns success/fail
* Need to check return state and continue or exit outer method
I personally think Case 1 looks a little cleaner but it breaks more

Hello, i have a problem with replacing c++ exception handling with
structured exception handling. How to replace the " catch(...) " in
c++ exception handling with, __except , a structured exception

If i write "#define catch(...) ----" ; then it doesn't take ' ... ' as
a string ; so, prompts an error.. error C2010: '.' : unexpected in

Ok something simple like int.Parse(string) can throw these exceptions:
ArgumentNullException, FormatException, OverflowException
I don't want my program to just crash on an exception, so I must
handle all of them. I don't care about which one happened, except to
write out exception.Message to a log file. It seems verbose to write
out three handlers that all do the same thing. So, I could just catch
Exception. But, is that...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
