On my .NET web project I am trying to make an asyncronous call to a function
using IAsyncResult. The function will process for about a 1/2 hour. before it
completes, the process abruptly ends as though it has timed out. I'm not sure
what is timing out. Would it be the page I am making the async call from? Or
possibly the connection/command objects I am using to connect to my sql db?

I'm quite new to object oriented programming, so this is probably a really
basic problem that there is an obvious solution to, but anyway...
I am looking for a little advice on a good way of storing a list of channels
for a video capture application. I have a channel class that contains
information such as the tuning frequency and the channel name. I then want
to have a channel list class which is used to store the channels and their...

Hi.
I use System.Drawing.Bitmap to work with bitmaps.
I use LockBits to retrieve a BitmapData which in turn provides me with the
Scan0 property which i then use to loop the pixel data using byte *.
I am aware of that internally GDI+ stores RGB as BGR,
therefore i have to to a manual swap for the R and B components of each
pixel.
This works when the image contains no alpha channel,
but when an alpha channel is present (Format32bppArgb)

title: asyncronous Socket and EndAccept()
question: hi to all, I am working with a server that uses the sockets in a
asyncronous way. When I want to STOP the server I do the following:
- serverMainSocket.EndAccept();
- serverMainSocket.Shutdown(SocketShutdown.Both);
- serverMainSocket.Close();
My problem is on the first instruction. I don't know what can I put as
argument in the EndAccept().

Hello!
I was looking at marking objects with a changed state, once properties have
been changed. The reason behind this is, that I would like to enlist such
objects for processing in a transaction.
The example below illustrates a sample pattern, which is fine when exposing
simple value types.
However, when exposing reference types, it becomes really hard (if not

Hi,
I made an application that foreach directory that found in the hardisk
create a node into a treeview.
Of course, to avoid that the user interface gets blocked, i use a handler in
a syncronous way.
The problem is that when i execute the application and click a button to
fill the treeview, dont fill anything.

Hi,
I have written a small C# 2.0 DLL which acts as a client to a Socket
based server over the internet. I have written both synchronous and
asynchronous methods to connect, send, and receive data from the
server. Each request/response can take upto 180 seconds. I am trying to
use the asyncronous calls in an ASP.NET C# 2.0 Webcontrol, which
displays the returned data. At the moment I am happily using the
asyncronous functions and events...

I've developed a ASP.NET website which is running on a Windows 2003 Server
with IIS6. I need to be able to run an asynchronous task that checks a POP3
mailbox, processes an email, writes data into the database and send SMTP
emails back out. All of this is implemented and working fine except the
asynchronous task bit.
In a traditional client/server environment we'd probably write a service to
carry out this operation. The same is...

Our company just allowed asp.net to be used internally here at my job.
I am in the process of getting the software. My boss wants me to have
some sort of way to capture load times in various places. I understand
trace and how to turn it on but apparently this is not good enough. Is
there anyway without writing my own code to do some sort of process
time checking and just printing it to the screen but making them
specific to different...

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,...

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...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
