After over a decade of programming in C++ I seem to have missed some
substantial point (mental note: am I getting too old for this?). A
little bit of help would be *very* appreciated.
I'm trying to gather various different classes into a common namespace
using typedefs:
class QWidget {};
class MyListview {};
namespace gui

Hello, I'm trying to accomplish the impossible by trying to do something equivalent of this example found here
http://www.c-sharpcorner.com/Code/2003/Dec/DialogTutorial.as
Starting with "Listing 2 - Changing the constructor of the modeless dialog to accept the parent object:" line and go onwards is what I'm trying to do
Basically, there is the main form, and then there's the modeless form. I want the modeless form act like a modal form,...

Hi all,
I'm trying to use forward declaration with value class but I don't succeed
in compiling my (quite simple) sample code.
This is my code I'm trying to compile (Visual Studio 2003)
namespace managedDll
{
public __value class VecDouble;

Thanx for the quick reply. Your suggestion would mean that I'd have to add a C# reference to any C++ module
that includes the C++ header. There's lots of them and I'd (for the moment) like to have the C++ <-> C#
interface encapsulated in one C++ module.

Hi,
I have two namespace contains class InkFrame and PrefDialog
respectively. PrefDialog needs InkFrame to show the dialog over the
frame. It also stores a pointer to InkFrame inside it.
Now I want InkFrame to be forward declared in the PrefDialog header
file rather than to be included. I want to include it in the cpp file
instead. There is no harm including it in PrefDialog header, and it
works. But I want to save some compilation time....

I have the following problem in a C project (but that also needs to
compile with a C++ compiler). I'm using a virtual function table, that
looks like this in the header file:

const device_backend_t *backend;
...
} device_t;

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...
