I've been struggling with this question for a while. What is better
design? To design functions to return error codes when an error
occures, or to have them throw exceptions.
If you chose the former, i have a few questions that need to be
answered.
1) What about functions that need to return a value regardless of the
error. How can they also return an error code unless the function has
"output" parameters. This seems messy and...

People say that is a bad technique to throw exception from
constructors; and that the solution would be to create a function
_create_ to initialize an object.
What about copy constructors? How can we avoid throwing exceptions? If
we already have an abject witch was initialized wit _create_ we will be
forced to call create in copy constructor and to throw exceptions from
it.
Have a nice day,

Hi All,
I have a problem in throwing custom exceptions from a webservice method.
The custom exception is being converted into soapexception in the webservice
client. only the custom exception message is present in the soapexception .
Is there any way to get the exact custom exception instead of soapexception?
Thanks in advance

Is it appropriate to throw exception from a constructor?
Thats the only way i could think of to denote the failure of
constructor, wherein i am invoking couple of other classes to
initialise the object.
TIA

This is a long one, so I'll summarize:
1. What are your opinions on raising an exception within the
constructor of a (custom) exception?
2. How do -you- validate arguments in your own exception constructors?
I've noticed that, f.ex., ArgumentException accepts null arguments
without raising ArgumentNullException. Obviously, if nothing is to be
supplied to the exception constructor, the default constructor should

Hello,
I have a c# com object that exposes several methods.
This com object is to be used in vbscripts as well as vba scripts.
In my application error handling is done by throwing different types of custom exceptions. The problem is that when theses exceptions are caught by the vbscript the type of the exception is unknown.
Therefore I would need Err.Number to determine what kind of exception was thrown. Unfortunately I have not been...

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...

Hello
I'm a network technician in training and I need your help.
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...
