The C++ book I have to hand (Liberty and Horvath, Teach yourself C++
for Linux in 21 Days--I know there are better) states that "static
member functions cannot access any non-static member variables".
However, this doesn't seem entirely correct. It also doesn't mention
whether static member functions can access protected and private
member data and methods (and I couldn't spot this in the FAQ).
I have a class row<Row> which derives from...

Please help
I don't know if this is possible but what I would really like to do is
to use On Error Goto to capture the code that is being executed when
an error occurs.
Any help would be much appreciated.
Thanks in advance

I need advice on correct usage of ADO.NET in an ASP.Net environment.
I have an ASP.Net application that accesses data through a referenced
class library. Things start to break down when multiple web clients
attempt to use the application at the same time. A common error that
gets returned is "sqlcommand is currently busy open, fetching".
I can't understand why the users might be using the same instance of
my connection, but this error...

I am finding that time after time I have instances where I need to access
information in a variable that is public. At the same time, the books I
read say that one should not use public variables too much - that it's bad
programming practice. Is there an easy way to deal with this? I would like
to do things in the "Best Practices" way but at the same time I don't want
to make a federal case out of it.
This comes up over and over...

Does anyone know how to declare a variable in a class to be accessible ONLY from a classes instantiated within that class?
For example:

Hi there
Is there any way to access private variables directly from within a
priviliged function? I have a situation where the priviliged function's
execution context contains variables of the same name as the parent
context, but I want direct access to the parent context's variable.
E.g. I would like to be able to do this...

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,...

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...
