When design a class, should always make it "derivable" as a base class? Is
there really a situation that the designed class not "derivable"?
When should make a member "protected"? Only when allowing the derived
class(es) directly access it?
Should destructor always be virtual?
Thanks for your comments!

Hi all,
Having problems designing a template-class. I'll describe my scenario
first then show what I've come up with so far:
Need a class to provide pointer/array-like access to an area of physical
memory
located on a piece of custom hardware - this memory is only accessible
using machine specific i/o so I want to hide all this in a class. I'm

Hi everyone,
Having learnt a little about the basics whilst creating my first db I
am now about to start creating a good one!
I am about to sit down with a large piece of paper and plan it all
properly but I have some questions about logistics I wondered if anyone
could help with.
1. Can I put command buttons on a table or query?

Hi All,
I'm having quite a bit of trouble designing a search tool to work with
my database. I have found lots of examples from Microsoft Templates
to Allen Browne's sample search form. The latter looks very
promising, but I need to incorporate a combo box with "Nurse Care
Managers" and have it filter by this. (Right now, I'm being asked to
enter a parameter value and I can't figure out how to fix this.)
I need to be able to search...

What sorts of things should I look out for if I'm designing a webpage
specifically for use on mobile phones or PDA's? Obviously smaller is
better (in terms of the overall page) but there's probably a lot more to
this.
I have an example of my first attempt at:

This is simply a non-functioning capture of the page, showing how far I
haven't got.

Per ex: agents are talking to customers and the supervisor is
listening to their conversation (and grading them as per a specific

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:

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.
