I have a named mutex object that is accessed by both an asp.net application
and a Windows executable .net application. The Windows executable runs
under the administrator logon, while the asp.net application runs under the
standard asp.net user account. The problem relates to permissions on
creation of the mutex. If the asp.net application creates the mutex, the
executable cannot access it (access denied error). Likewise, if the...

I am using the following piece of code to ensure that my application only
runs once, however I have a few questions about it.

static, so are the private members

I was just thinking about this, specifically wondering if there's any
features that the C specification currently lacks, and which may be
included in some future standardization.
Of course, I speak only of features in the spirit of C; something like
object-orientation, though a nice feature, does not belong in C.
Something like being able to #define a #define would be very handy,
though, e.g:
#define DECLARE_FOO(bar) #define...

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

Hi. I'm reworking a little app I wrote, in order to separate the data
from the UI. As a start, I wanted to create a iron-clad data recepticle
that will hold all the important values, and stand up to being queried
by various sources, perhaps concurrently. In all likelihood, the app
will never need anything that robust, but I want to learn to write it
anyway, as an exercise. So here is my code. It's really simple, and I'm
sure you can see my...

Problem 2: Threading:
Requirements: In a particular system there are two threads T1 and T2.
T1 is the master thread that periodically sends messages to the worker thread T2.
The system is time-critical and hence T2 must react to every message that T1 sends.

Hello, i'm trying to program a thread that would be locked (by a
mutex) and that would only be unlocked once that a function
(generating data) is done. The purpose is to generate data, and unlock
the mutex in order to activate the thread once the data is generated.
I have to do it this way, i can only call the thread if the data are
generated.

Given an object of type Mutex, what method or property should be called to
determine if it is currently owned?
I could call WaitOne(0,false) -- and if the return value is false, I could
deduce that the Mutex is already owned... but this has the unwanted side
effect of seizing ownership of the Mutex in the case where the Mutex is NOT
already owned.
I'm looking for something like an "IsOwned" property.

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...

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,...
