Hi all
I'm facing a strange problem in C++ exceptions.
If an error occurs in a class, throw() is used. But whenever that
happens, the object is destroyed.
In a nutshell, accessing the object in which exception occured is not
being possible in catch block.

Hihi, i am writing utilities classes using C#. The utilities contain my own
exceptional classes. Until now, my design about the exceptional classes is
that:
I have my expceitonal class and inherit from ApplicationException and i will
assign a message to it when creating the instance for more details to
identify what's the problems are. The message is not hardcoded in program,
the exceptional classes will call and pass MessageKey to a...

I am puzzled by something. I have a program foo.cs it has
a reference to an assembly bar.cs. The latter
intentionally performs a divide by zero. The former has a
try/catch pair for the offending method invocation which
works in 2/3 of the cases I have tested. I am calling the
bar.method() (which returns a string) as the first
argument to MessageBox.show():
1) Running in the debugger - works
2) Running from bin/Debug - does not...

Some programmers, and even Microsoft documents, say you should only
throw exceptions for exceptional situations. So how are others
handling all the other unexceptional errors? How are you propagating
errors up the call stack?
In the past, in my C++ code, I used to throw exceptions for ALL errors,
exceptional or not. It seemed like a nice clean method for detecting,
handling, and propagating errors. You can find multitudes of articles...

Is the following code (without any code at lines x and x + 3) correct?
Is it better to call exit() or re-throw the exceptions at line x and
line x + 3?. What is the better code should we place at line x and
line x + 3?
try {
cnn = env->createConnection(user, pwd, db);
} catch (SQLException &esql){
cerr << "DB Exception: " << esql.getMessage();
/* line x ? */

Hello,
I am looking for an example of a constructor, I think,
which took the type itself for integral or floating types,
and a const-ref for a user-defined non primitive type.
I saw this in one of these books but I can't find it now:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...
