Hi,
I've got a question about whether there are any issues with directly
calling attributes and/or methods of a threaded class instance. I
wonder if someone could give me some advice on this.
Generally, the documentation suggests that queues or similar constructs
should be used for thread inter-process comms. I've had a lot of
success in doing that (generally by passing in the queue during the
__init__ of the thread) and I can see...

Hi,
we have a contention problem because of an application which tries to
insert a duplicate row in a table with primary key. This insert fails
of course but the locks are not released within this transcation.
Why DB2 does not release the X lock after a failed insert???
We use DB2 UDB EEE Version 7.2 Fixpak 9, but we also can reproduce the
Problem on DB2 UDB ESE 8.1 Linux Fixpak 4.

DB2 v7.2 (FP7 - DB2 v7.1.0.68) on AIX 5.2.0.0.
We're seeing unexpected single row (then commit) insert locking
behaviour.
We're seeing Applications that already hold row-level W locks in
lock-wait, waiting to acquire row-level X locks. The lock-waits are
behind applications that have row-level X locks on different rows
(honestly). Both executing and lock-waiting applications have been
granted IX table locks.

Ok, I'm a little rusty on this, it should be a simple problem but I
can't figure it out. How can I handle form events in my main code
page??
I'm creating a Windows App in C#. Rather than make my main form the
startup object, I'd rather put my Main() function in a class or code
file. Why? Because thats what I always do in standard C++ or VB. In
my opinion, writing all my application logic in the form itself is
sloppy and only for...

I am reading events from an event log on a remote server. Certain events
will be put in a file or some other form of output. Everything works fine
but I am concerned a potential problem. Reading about how events are
handled, I found that the message property of an event is not recorded but
rather accessed from the source dll file. While testing my code I found that
when accessing the message property of a remote event log the message is...

I have a service that checks the event log for certain types of error
messages. It kept locking up so I put in debugging code to see where
the problem was. It's locking up when I call the property
EventLogEntry.Message. I have search message boards and have found a
few people complaining that this property throws a strange exception.
It doesn't just lock up the thread that is calling it, but it locks up
other unrelated threads too. In...

Timeout Calling Web Service
I am calling a .NET 1.1 web service from an aspx page. The web service can
take several minutes to complete its tasks before returning a message to the
aspx page.
If the web service is taking a long time to complete, the aspx page returns
a ‘The operation has timed-out.’ Message to the web browser after 100 seconds.
I’ve added: <httpRuntime executionTimeout="300" /> to the web.config files

I'm using vs2005, .net 2.0 on Windows 2000 server.
When I double click on an entry of the "Security" log in the system's "Event
Viewer", a Property window pops up. In this window, there is a "Description"
section that lists many different information like "User Name:, "Domain",
"Login ID"......
How can I obtain each of this inforation in my program? Thank you.

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...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
