Hi,
I have a problem with a home-made DLL used in an ASP environment. It
is coded in VB6, apartment-threaded.
The DLL returns a binary PNG stream (an image). I use it with ASP's
Response.BinaryWrite to display a dynamic image on a web page.
The server is Windows 2000 SP4.

I apologize for not doing more on the attempted "Correct C++ Tutorial"
earlier, but there were reasons.
This is an UNFINISHED and RAW document, and at the end there is even pure
mindstorming text left in, but already I think it can be very useful.

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

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
