We have ported our VB 6 application into VB .NET but are still integrating with a few COM + applications written in VB6 running on our application server (Win 2000 Server). We have the proxies to link to the application server installed but we every now and then get a error when we try to make a call to a component running on the app server. The error message is something like

Hello,
This error does not occur on my machine, but does when I move to our
development web server (Heard that before right?:-))
I am trying to execute this line in my code behind so that I can start to
programatically build a word doc, but it fails everytime with an 'Access

I have already used a third party com object in my code,
and it went easily. Add the reference, call the methods,
and get my results.
But I am integrating a legacy com object and I follow the
same steps, the auto complete works, the compiler likes
my code, but when I test, pressing the button that
triggers the code segment gives me an access is denied
error and a stack trace that claims the problem is in my
instantiation. (Error cut...

I have a function that takes a reference to a class, and then
instantiates that class (and then does several other things with the
new instance). This is easy enough:
item = cls(self, **itemArgs)
where "cls" is the class reference, and itemArgs is obviously a set of
keyword arguments for its __init__ method.
But now I want to generalize this to handle a set of mix-in classes.

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

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

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...
