Hello,
I'm having a strange problem that is probably due to my lack of
understanding of how threading & COM Interop works in a WinForms.NET
application.
Here's the situation:
I have a 3rd party COM component that takes about 5 seconds to run one of
its functions (Network IO bound call). Since I dont want my GUI to freeze

I have a UI that needs a couple of threads to do some significant processing
on a couple of different forms - and while it's at it, update the UI (set
textboxes, fill in listviews). I created a base class for the worker class,
and made up some functions/delegates to handle the invoke stuff for the UI
and that was fine for a prototype. I rewrote this chunk, broke things out
into different classes - but the threading is still the same - and...

Hi:
I am writing a WinForm app that contains a DataGrid control and a StatusBar
control. My goal is to update the status bar using events from a separate
class, as well as some other simple things.
The method I am writing queries a large dataset. As part of my feedback to
the user, I am updating the status bar when the connection is made and the
dataset is actually retrieved. The dataset retrieval method I have placed on
a separate...

I have a web service that I believe needs to implement threading. I
have a timer setup to fire 3 requests and have them do some
calculations and send the info to the mainform. I also need the click
events on the mainform remain in real time. Through a little
experimentation it seems that I can only use 1 sub to update the form
to avoid cross threading. So maybe have the timer fire the 3 requests
and then when they are complete fire the...

Hi guys,
I have this page that needs to be populated with 2 diferent web services,
and each one takes more or less 10 seconds to finish populate his own part,
so I move on to the multi threading inside ASP.NET.

code will make more sence of what I am trying to accomplish. I am just not
sure of what to search for on the net.

form ( main form ).
Anway...in this child form I have a button, and if clicked a bunch of code

For an application I'm creating I want to create a 'fake' progress
bar.
By fake I mean a progress bar that looks like it's doing something but
actually isn't.
I know philosophically this isn't sound. But my little app is a 'fake'
app and is designed to look like another - hence this seeming crazy
situation of needing to fake a progess bar.
PROBLEM.

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

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...
