Also, how do I call/manage smart pointer interfaces?

I'm writing a small console app in .NET that needs to reference a 3rd
party dll.
I wrote the app by adding a reference to the 3rd party dll in my
project and my code builds and executes perfectly. However, when I
made a setup file and installed it on another box, I get:
System.InvalidCastException: QueryInterface for interface...Failed.
when the console app tires to reference the dll. I can see that the

I have just started using VB.Net and I am developing a class to provide data
to clients from an IBM-MQ queue.
I have developed a class which connects to the queue and issues a read. When
a message comes in an event is raised back to the client containing (at the
moment) only the message id.
This all works fine but the MQ read call blocks and prevents other processing.
To overcome this I have created the object and then start the...

Hi,
Our app uses a 3rd party dll with ActiveX controls that is installed and
registered by the setup.
We have a customer who has installed on Win2k and is getting this exception
when the app tries to use the dll (stack trace below). Other features
of our app work correctly. We have not been able to repro the issue on our
own
Win2k test box. Below the stack trace are some notes about things we tried and
the results. Any help will be...

the DLL. The new version was successfully installed on our production server,
and ran without problem for 2 weeks until a scheduled reboot of the server
occurred. Since the reboot, the application always fails...

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...

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,...

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.

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...
