Hi,
I am trying to create a class which downloads a web page in the background
and then raises an event in the original thread in which it was created.
This class is going to be the basis of a set of different applications and I
want to hide the threading from the other layers. Any suggestions as to how
to do this?
Thanks
James

I've created a pocketpc app which has a startup form containing a listview.
The form creates an object which in turn creates a System.Threading.Timer.
It keeps track of the Timer state using a TimerState object similar to the
example in the System.Threading.Timer documentation. The method which
handles the timer events, among other things, periodically calls a method in
this TimerState object which raises an event to the startup form,...

Hi all,
How Can You Raise Events Asynchronously ?
Now for the details ...
I want to do inter modular communication using events in such a way that the
contributing modules need not maintain the reference to any module.

Hi all.
I ran into quite strange problem concerning the event raising inside
FileSystemWatcher Delete event.
First, i would like to describe a bit my environment.
I have main GUI application, which uses other class libraries.
One lib, called Utils.dll contains custom collection implementation.
This simple collection just overrides Add and Remove methods to raise

Hi,
I have an app with the main thread and one additional thread.
In the main thread I defined an event handler MyHandler, the function for
raisin this event OnMyEvent and the function for processing this event MyFunc.
I want to raise this event from the second thread. Is it thread safe to call
the method OnMyEvent from this second thread?

Hi all,
I would like to write a class (Task) with a method to do some lengthy
process based
on several of the class properties. The method is running on different
thread.
During the execution of the method, the class is suppose to fire events such
as
ProgressChanged. And it raises Completed and Failed event on completion and

So, let's say that a user enters an event name in text box, and would like
to raise it..
is it possible to call events by their 'name'?
Is it possible to enumerate events inside app. and to check their names?

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...

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...

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...
