long process (webservice call)
if that webservice call fails, i want to raise an exception and display a
messagebox.
however no matter where i put the Try block to trap the error, it does not
work.

Hi,
I'm having some weird problem using the BackGroundWorker in an Outlook
(2003) Add-In, with VB.NET 2005:
I'm using the BackGroundWorker to get the info of some mailitems, and after
each item I want to raise the ProgressChanged-event to update the
DataGridView.
It works fine when only one Progresschanged is fired, but at the second,
third, fopurth etc it raises everytile a 'Cross-thread operation not
valid"-exception on lmy...

I am trying to set a panel (that holds a progress image) to be visible
when a long running process is happening. Sounds simple, right :) What
happens is the panel never becomes visible. The load and prerender
events occur, but it is never displayed.
In the super simple example, I use the "hide panel", then click the "Do
Process". The next thing I see is the "done". Why won't the panel
display?
Here is the code:

I have a background worker thread that scans the network listing computers
that are connected. I have a delegate that I call that invokes a procdure
that loads a dataset with computer names and then attaches it to a dropdown.
When I run it, my UI freezes until it completes. Any thoughts on how to do
this without freezing the UI?

Is there a way to immediately terminate a BackgroundWorker thread? My
problem is that the BackgroundWorker starts with a call to
My.Computer.FileSystem.GetFiles that can run for a very long time if
it is pointing to a directory tree with many files. If the user
requests cancellation during this time, the main thread can call
CancelAsync and can post a "Cancellation Pending" message to the user,
but the BackgroundWorker cannot respond to...

Hi,
I have a form with a progress bar on it and wanted to use the
BackgroundWorker to be able to update the progress. I looked at examples, run
some of them, but in debug, when the code gets to the do work method, it
stops for a long while and then executes the first line of the method and the
doesn't do anything else.
What am i doing wrong?

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

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,...

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...
