I have some C# code that is supposed to wrap the defrag APIs and I am trying
to convert it to VB.Net (2003). But, I keep having problems.
The C# code is relatively short, so I'll post it here.....

I've seen lots of examples out there for low-level file access but can't

this?
Below is my code thus far...

Hello, I have been taking a swing at learning how I can use Impersonation via
code and I am getting back an error code of 1314. By searching the internet,
I have come to believe that this error means the account it invalid.
If I use my ID and password, the code works fine, so I am guessing it is not
the code.
I requested this "special" account from the network folks and have been
using it for submitting batch Console applications from my...

Hi there,
Does anyone know if this (example) is safe:
internal static extern int GetWindowRect(IntPtr hWnd, ref RECT
rect);
int rc = GetWindowRect(hWnd, ref rect);

GetLastWin32Error exposes the Win32 GetLastError API method from
Kernel32.DLL. This method exists because it is not safe to make a direct
platform invoke call to GetLastError to obtain this information. If you want
to access this error code, you must call GetLastWin32Error rather than
writing your own platform invoke definition for GetLastError and calling it.
The common language runtime can make internal calls to APIs that overwrite

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

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....
Now, this would greatly impact the work of software developers. The idea...

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...
