Hi,
My application has a need to cache a number of shared reference lists
containing basic business objects. In order to improve performance these
lists are fetched and updated in the background.
When a UI is required to display one of these reference lists it requests it
by name from the cache. If the list already exists in the cache it is
returned to the caller otherwise a brand new empty one is created and
returned. This new empty...

I have an object that starts a thread to do a "process". One of the steps
inside this thread launches 12 other threads via a Delegate.BeginInvoke to
process. After these 12 threads are launched, the main thread waits. At the
completion of each subthread, the mainthread checks all 12 thread objects to
see if they are done. If they are, raise an event that says we're done.
So, it's kinda like this:
ProcessThread
- Creates a ProcessObject

I'm using a BackgroundWorker to perform a file download from an ftp site.
Per good code design practices where I separate my UI code from my core
logic code (in this case my Download file method in my FileIO class) I've
established Public Event in my core logic classes along with RaiseEvents
(that will updated a progress bar on the UI side). This all works great
when I'm NOT using Threading (BackgroundWorker), however, as soon as I...

Hi all,
I am migrating a Windows Form application from .Net 1.1 to 2.0. I try to
use BackgroundWorker object to handle a very lengthy process.
I have a separated class to handle some very complex logic. In .Net 1.1,
I create some events inside this class to notify WinForm the status of
process:
obj.OneFileStarted += new OneFileStartedEventHandler(obj_OneFileStarted);
obj.OneFileFinished += new...

I'm completely new to using background threading, though I have
downloaded and run through several samples and understood how they
worked.
My question is:
I have an app whose primary form will almost always lead to the user
opening a certain child window that's fairly resource intensive to
load. Is it possible to load this form in a backgroundworker and then
use the Show method and hide method as necessary? Anyone know of

I understand delegates (static and non-static) and I agree they are
very useful, and that the "Forms" used in the Windows .NET API could
not work without them. That said, I'm curious as to how many heavy
duty pro programmers in this newsgroup have actually used a delegate
in their code, say in the last year of coding. By "use" I mean
constructed a delegate and using it in an Event Source class and an
Event Receiver class.

Greetings,
I believe I have narrowed down my issues to one simple question, and I'm hoping someone with async events experience can help me out.
My question is: how is using EventsHelper.FireAsync() different from using EventsHelper.Fire() BUT having the listener's event handler spawn a new thread to do the work?
In my program, I have a data feed coming in and I have a separate form that has a DataGridView on it. Each time a message...

I have a timer. At each tick, say 0.1 second, I write a file.
If it takes more than 0.1 second to write the file the app will not work
correctly.
How can I tell in the tick event if the previous file finished writing so I
can skip writing at that time?
I write using the Bitmap.Save method.

Hey,
I'm trying to find a way to raise events from a thread or a delegate in such
a way that it will not require the use of invoke when you are updating the
gui. In other words, make the event delegate trigger form the caller thread.
Today I'm doing this by finding the main form and invoking the event
delegate for there. But this method seems "to dirty" to be the best
solution.
Does anybody know a proper way to do this, or what I have...

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,...

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....

Hello
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...
