I've been discussing here a SQL 7 view which scrolls slowly when linked to
an Access 2000 MDB. After trying various things, I've distilled it down to
the following: when the linked view has a virtual primary key, it is slow;
when there is no virtual primary key, it scrolls quickly.
Looking at Profiler, I see that when there is no virtual primary key, Access
sends a simple select command to SQL Server. However, when there is a

Hi
I use the following syntax to have events inherited from base to child classes which works nicely (virtual and override keyword on events). But I am wondering if it is a "supported" way of using events since I never saw it used anywhere in MSDN documentation/samples?! Or it will just break when I upgrade to .NET Framework 2.x in the coming years
namespace MyNamespac
public delegate void MyDel()
public class MyBase
public virtual...

Since no one else knew how to do this I sat here all morning experimenting
with this and this is what I came up with... Its an example of how to get a
list of items back from a virtual mode list view in .NET 2.0 with multiple
selection turned on... since the .NET documentation is EXTREAML vague on how
to do this and offers no clue on what the virtual mode events do or how to
use them... just thought this might help someone else out...

Here is another virtual mode example for the .NET 2.0 framework while
working with the list view. Since you can not access the items collection of
the list view you need to do sorting another way... here is my code on how I
did it to help anyone starting out get an idea of how to use virtual mode in
..NET 2.0

Are ALL methods in subclasses implemented in C# with vtables and virtual
functions?
I know I could test this myself, but I'm still using Express edition of 2.0,
so I cannot view the optimized disassembly.
I know that you must use vtables for all virtual functions (and interfaces),
but if there are non-virtual functions, does the compiler use a vtable for
everything anyway?

Hello,
If I have a class that has virtual but non-pure declarations, like
class A{
virtual void f();
};
Then is A still an abstract class? Do I have to have "virtual void
f() = 0;" instead? I think declaring a function as "=0" is the same

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,...

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