Dear all,
This is more like a theoretical or conceptual question:
which is better, using exception or return code for
a .NET component?
I had created a COM object (using VB6), which uses return
code (not generating error/exception) so it is more
compatible with other programming language.

Hi,
Can someone tell me how to perform exception handling in DB2 UDFs(not
procedures).
ALso, while usin the SIGNAL statement in one of my UDFs I encountered
an error message which is as below
DB21034E The command was processed as an SQL statement because it was
not a
valid Command Line Processor command. During SQL processing it

Hi guys,
For my VB.NET application, I created an ErrorHandler class that should save
all available information about the last error occurred. I use
Server.GetLastError for this.
The problem is that I quite often get errors that I really can't say why
they happen because of the lack of information from GetLastError. This is an
example:
System.NullReferenceException: Object reference not set to an instance of an

There are situations where you want to retry/rerun the same code again (if
user wants) for unlimited times for a particular exception thrown. For
example in situations like there's no CD in the drive or some file is locked
by another process you want to display message dialog to user with "Retry"
and "Cancel" buttons (As Windows shows "Retry" option if no CD in drive) and
if user clicks "Retry" you want to run the same code again that...

The simplicity of stack unraveling of C++ is not without defective
consequences. The following article points to C++ examples showing the
defects. An engineer aware of defects can avoid hard-to-find bugs.

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...

In all the sample code snippets of try-catch code blocks that I have
seen, the catch block does one of the following three things:
1). exits the program (after spitting out a cerr message)
2). propagates the exception
3). throws yet another exception
I have a need to do something different. I want to merely spit out a
cerr message when I catch an exception, and then proceed with my
business logic. I am thinking of something like...

Hello:
As an avid reader of C++ books, I know a lot of programmers out there
are confronted with the challenge of exception safety.
For those who don't know what it is, it is writing code in such a way
that an exception will not cause a class to be left in an unstable
state. For instance, you wouldn't want an OutOfMemoryException leaving
a container with an invalid size or missing elements.

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:

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,...
