We have a time critical smart client application running on Windows 2000/XP
systems.
Is there any reliable service that would help in syncing the local system
time to atomic clock or local time at the least in case the user changes the
system clock in purpose or inadvertently?
- Network synchronization solutions in the network is manual I believe?
- Web service based sync could work but will not if the user is off line.
Any other...

Hi,
I just tried to convert my current project to the new beta 2 of the .net
framework and I encountered some problems with my thread synchronization -
that formerly worked well.
When I release a monitor by System.Threading.Monitor(myvar) I receive the
following error message:
System.Threading.SynchronizationLockException: Object synchronization method

I would like to use the timestamp on files to manage the
currency of support files for my VB windows application.
In this case I would only put the timestamp of the file
in the management database and not the file itself.
To do this I will need to have a File class property for
Create time and date that will let me "set" the Create
time and date of the file to my own chooseing.
The VB file class does not appear to have the ability

I get this *intermittently* on a utility I am working on. I don't know whats
going on but here are a few points about it:
- using VS 2005, running on xp sp2
- program uses multiple threadpool threads
- only happens when built with the 'release' configuration (no debug flag,
compiler optimizations in effect) - no problems in debug config
here is the error:

I have a class that instantiates two Timer objects that fire at
different intervals. My class can be instantiated within a Windows
Form or from a Windows Service. Actions performed by one of the event
handlers may take longer than the interval for either of the timers,
so it's possible for multiple events to fire "simultaneously" and for
events to queue up. I'm attempting to get the timers to sync on some
reference type object, or use...

I am relatively new to C# (although I have a lot of programming

searching for a solution to this problem:
Suppose you have 3 methods A, B and C. All of them shall be run

Hi all!
I have a question about thread synchronization and c++ streams
(iostreams, stringstreams, etc). When optimizing a program for a
multicore processor I found that stringstream was causing a LOT of
synchronization overhead. After a bit of digging I concluded that this
synchronization has to do with the access to a global locale inside
the stream.
The problem can be seen by running the small distilled benchmark code

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...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.
