I'm trying to set up a class factory for loading classes from a
database. Each table will be loaded into it's own class with a common
base. Just thought I'd try a simple sample first, but I'm having
trouble getting it to link. Here's the code and output:
class c1{
public:
virtual void fn()=0;
};

hi, there
I build a Class Library, I write a class A to implement interface IA. The
problem is when I give the dll file to others, thet can get all information
about not only IA, but also A. They can even see my protected members of
class A. How could I hide these informations about class A, just give them
the interface informations.
thanks.

Is there a way to prevent classes from being instantiated by methods other
than my factory pattern?
I have a couple of classes and want to force the factory class to be used as
the "entry point".
Any help is appreciated,

Hello!
We have written a GCryptoSvr.dll COM server in C++. Inside that resides
WebClient COM component. WebClient CLSID is
{8DC27D48-F94C-434B-A509-C3E1A3E75B9E}. When we are using that WebClient
COM component from C++ code it works just fine. However when we try to
use that same WebClient in the same machine with following C# code:
using GCRYPTOSVRLib;
WEBClient WC = new WEBClient();

Hi, I recently wrote an ASP.Net web application in VS2005 and published
(using VS2005 Publish feature) it to a relatively clean machine with

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,...
