I have never written a trigger before and now am seeing the light. Is
there a way to write a trigger so that if a user changes any column in
a single row on one table then the trigger will write the value of
this (these) rows to a second table. I don't want the unchanged
columns, just the changed columns (with column names...)
Thanks,

The DataGrid allows you to make columns visible or invisible on demand
- even edit and other special columns. This article will show you how
it is done.
Some developers have reported problems controlling the visibility of
columns in the DataGrid control. The problem usually comes down to one
fact. The DataGrid has a property called AutoGenerateColumns. The
default value is "True". This means that when AutoGenerateColumns is
set to True,...

the columns show long text boxes whichmakes the user to SCROLL a lot.

how?
2. Also, even when the data grid is not displayed in the edit mode, it

I was thinking about developing a workflow application yesterday and was
musing over the different approaches than one could take in restricting
specific actions on a ticket( Form ) at any said stage.
One approach I have used on other systems is to prevent the action buttons
appearing. For example, if one did not have the Role of Administrator, one
would be prevented from deleting a ticket not created by oneself.
However, it did occur...

I made a form with a datagrid called MyDG. The datagrid has a typed dataset
as datasource (MyDS).
I put the following code in the load event of the form to hide the id column:
MyDS.MasterTable.IDColumn.ColumnMapping = MappingType.Hidden
Strangely, when the datagrid appears for the first time, the id column is
visible, then, when I expand a row, click to visualize then details and click
in the back button to see the master again, the...

Hi,
first, python is one of my fav languages, and i'll definitely keep
developing with it. But, there's 1 one thing what I -really- miss:
data hiding. I know member vars are private when you prefix them with
2 underscores, but I hate prefixing my vars, I'd rather add a keyword
before it.
Python advertises himself as a full OOP language, but why does it miss
one of the basic principles of OOP? Will it ever be added to python?

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,...

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.

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...
