I am instantiating a class in a switch statement as there are a number
of different overloads depending upon the data entered by the user.
The problem I have is that after instantiating my class, when I try to
call methods in the class later on in my code using the same object I
cannot, I get the error 'use of unassigned local variable'.
How do I get around this as I need some sort of switch/if statement to
instantiate my class?

I am trying to write a global custom error page. I thought I would jot down
some of what I've learned so far...
At first I just used the default customErrors section with a defaultRedirect
tag, as such:
<customErrors defaultRedirect="error.aspx" mode="On" />
First thing I found out about this method, is that I didn't have access to
the exception object in my error.aspx page. So this page was going to be

I wrote a webservices that should accept an exception object and log
info to a db. When I call the function in my webservices class I get an
error:
The type System.DivideByZeroException was not expected. Use the
XmlInclude or SoapInclude attribute to specify types that are not known
statically
Is it possible to pass an exception object as a parameter to
webservices??

Hello folks,

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...
