I have a virtual function in a base class, which is then overwritten by a
function of the same name in a publically derived class. When I call the
function using a pointer to the derived class (ClassB* b; b->func(); ) the
base-class function is called instead of the new function in the derived
class. All other similar functions (virtual in the base class and
overwritten in the the derived class) work fine, it's just this one
function. ...

Hi,
Continuing my strcat segmentation fault posting-
I have a problem which occurs when appending two sting literals using
strcat.
I have tried to fix it by writing my own function that does the strcat
(mystract). Program below.
However this appears not to have fixed the problem and I don't know why it
shouldn't ?
Any further help as to what else I am doing wrong will be appreciated

If I have a class with a virtual method, and a child class that overrides
the virtual method, and then I create an instance of the child class AS A
base class...
BaseClass bc = new ChildClass();
.... and then call the virtual method, why is it that the base class's method
is called instead of the overridden method? How do I fix this if I don't
know at runtime what the child class is? I'm using
Activator.CreateInstance() to load the...

Hello All,
I am developing an Input Methop (IM) for PocketPC / Windows Mobile (PPC/WM).
On some
devices the IM will not start. The IM appears in the IM-List but when it is

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

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 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...
