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...

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

Hi,
I have a WinForms desktop MDI application written in C#. Following advice
from others in this forum, I prevent multiple instances of the app running
at the same time by creating / trying to create a mutex, as follows:
bool blnCreatedMutex;
objMutex = new System.Threading.Mutex(true, "zzzzzzMyCoolAppzzzzz", out
blnCreatedMutex);
if (!blnCreatedMutex)

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

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:

I have various processes that are all logging to the same file using the same
function. In order to ensure nobody logs at the same time, I am using mutex.
The code I am using is listed below:
mut.WaitOne()
Dim l_fstream As New StreamWriter(l_logfile, True)
l_fstream.WriteLine(stringtolog)
l_fstream.Flush()
l_fstream.Close()
mut.ReleaseMutex()

Hi there,
I'm trying to understand the impact of killing a process that owns a
system mutex (used to ensure there is only 1 instance of my program
running)
Here is my code pretty much:
try
{
mutex=new System.Threading.Mutex( true, mutexName, out createdNew)

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:

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...
