In his book, "Modern C++ Design", Andrei Alexandrescu presents a Generic
Object Factory class (Loki::Factory). One of its advantages (also mentioned
in
the book) is being able to register the class in the factory without having
a
central place that needs to be modified each time we add a new type. For
example, the registration can be done in the same compilation unit as the
class implementation:

Hi ,
We have a lot of code which runs fine under VC++ 6.0. We have to move to
..NET becasue one of the librairies uses .NET classes.
Does every library(including those which do not use .NET classes) have to
be recompiled with /clr option?.

Hi
I have a project that consists of an unmanaged DLL (extended stored
procedure) and a static library, which I have converted to managed, although
it has got one unmanaged function which is exported to the unmanaged.
I keep getting the linker warning 'warning - images compiled with /NOENTRY
may not run correctly'.
It doesn't seem to have any adverse effects, but what does it mean and how
do I get rid of it?

After porting a project from VC6 to VC.NET 2003 I have a very strange
problem generating
link error 1104 for import libraries. I just ported the project and made
some small adaptions so
it fits the new IDE. The project itself links against some import libraries
belonging to dll's I
wrote (these dll's have been ported too, of course).
To keep things simple I only use one import library here. To tell the linker
it should link against

We seem to be having some problems in moving Application into the new
environment. My understanding is that Application in the current
environment makes use of 4 separate DB2 sub-systems, 2 of which are
in SYSA (production and UAT) and a further 2 in SYSB (development and
sys test).(on IBM Mainframe)
The new SYSC environment only has 2 DB2 sub-systems. Hence the
problem of trying to move 4 DB2 sub-systems into 2!

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:

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.
