Hi all!
In my app I implemented a separate worker thread that handles network
communication using Net.Sockets. It needs to make updates to a
DataTable object, which is displayed to the user by a DataGrid
control. The DataTable object is a 'public static' field instantiated
within context of the main thread.
The problem is that if I add a column to the DataTable from within the
worker thread (eg. different thread than where the DataTable...

Hi
I'm using several DataTables in my program which are updated periodically.
At the same I have those tables bound to DataGrids in my GUI. So far I've
been doing all the processing in the same program and the speed of the
processing prevented any issues when it comes to updating the GUI elements
(as DataTables are changed this triggers updates in the DataGrids), but as
soon as I add cpu time intensive processing options (i.e. receiving...

Entity/Table is called Log and contains the log-entries.

Hi everybody,
I need help for this problem:
I'm using a DataGrid to Insert/Modify/Cancel data from a single table.
At the moment, every cell modification of a pre-existing row is correctly
update on the DB.
I have some doubts about inserting a new row.
The table has a Id field that is a primary key defined ad Identity
properties on SQLServer engine.
This column isn't visible on the grid and a properties DefaultValue=0 is
defined.

returned to the calling client application built in windows forms within a
dataset, however upon attempting to create tablestyles to format any of the
columns within the datagrid, the exception "Can-not parent objects created
on one thread to objects created on another" or words to that effect.
I'm not too sure if what I said make sense, but i will add details to...

I have a sample of an unbound (autogeneratecolumns is true) sortable/pagable
datagrid that works.
I want to change one of the columns to a hyperlink. The examples I find use
a bound column. I can get this to work; however, the column header on the
datagrid is not a link/sortable.
What am I missing?
Thanks in advance.

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...

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,...

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...
