Here's a weird one...
The code below works just fine when I build in DEBUG mode.
Today, I tried to build my solution in RELEASE mode, and
immediately fell over this problem - apparently something
in the order or sequencing or something regarding static
initialization.
Consider this class, which implements a singleton pattern:

I would like to know the best way to initialize complex static member
variables. In addition, I want to avoid creating an Init() method
that is called by the ctor, since there's no need to wait for that
call in my application. My current attempt is OK, but it creates an
extra member variable that is extraneous:
<code>
class A {
private:
static std::vector<int> _v;

I use a mutex to disallow starting a second application instance. This
did not work in a release build until I made it static member of my
MainForm class.
In a debug build, first instance got ownership, second did not and
terminated. In a release build, the second instance *also* got
ownership. I "fixed" it by making the mutex a static member of my
MainForm class.
Did the garbage collector eat my mutex because it is not referenced

What is the right way to create an OCX COM component. The component is
already registerred, but can't create an instance. I am using the reference

Hi all,
I've recently been following the object-oriented techiques discussed
here and have been testing them for use in a web application. There is
problem that I'd like to discuss with you experts.
I would like to produce Javascript classes that can be "subclassed"
with certain behaviors defined at subclass time. There are plenty of
ways to do this through prototyping and other techniques, but these
behaviors need to be static and...

Hello,
I am just implementing singleton pattern in various ways. In one
implementation I created a static member and returning that static member in
the getInstance() function. I have made constructor as private and
destructor as public.

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,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
