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...

Hello,
I have an application that essentially consists of two threads doing
their things. One thread is a producer, and pushes bytes (of a struct)
into a pipe, and another is a consumer that simply checks the pipe at
regular intervals reads out the bytes. If the consumer extracts bytes
and sees that it's not enough to recast to the struct, it caches it and
waits for more bytes in the pipe.
My question is: Do I still need to maintain...

Hi.
I want to use the same mutex in different classes (web pages in an ASP.NET
application). In global.asax.cs, the class that starts up first, I create a
Mutex like this:
static private Mutex mtxBezoeken = new Mutex(false, "bezoeken");
which compiles and executes just fine. Then in another page I want to write
to a file that may also be accessed by global.asax.cs so I want access to

I want a (global) mutex which prevents a section of my code from being run by more than one process (or user) at a time. I have something that works, EXCEPT when there is an exception of some kind. It is possible for the user to generate an error and be able to "fix" the thing that caused the error (perhaps by changing some parameter) and then want to run the operation again from the same process. But if there's been an error, then he's out...

I've been having strange thread conflicts, and after moving the relevant
mutex higher and higher I've finally determined that the mutex doesn't
seem to be working at all.
Here is the relevant code:

private static void preview (string source, string target)

I am working in managed C++. I have a Mutex object in which I need to
replace the Handle property with a new handle. The new handle is being
constructed using Win32 CreateMutex call. I need to call the Win32 version
in order to set the security descriptor for the mutex, which is not natively
supported in .NET Framework 1.1.
I always get a little nervous about resource leaks when trying to bridge
Win32 with .NET, so I want to make sure...

I need to be certain my application only runs once on a machine, and I
implemented a solution using Mutex. The solution was posted many times, but
one great link I found is
http://www.yoda.arachsys.com/csharp/faq/#one.application.instance
The problem is, when I switch users (XP Professional) the second user can
open a second instance of the application! How can I prevent this?
Here's the relevant part of my code:

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.

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
