Hi,
I have a strange problem with my xml file. In the schema of this xml
file I have set one column to autoincrement. When I enter the data in
my xml file directly, the autoincrement-column gets its correct
values.
Now I want to add new data with the help of a dataset. I use the
following lines of code:

I tried to use the following example, to add a checkbox column to a
DataGrid in an ASP.NET application:
http://www.codeproject.com/aspnet/datagridcheckbox.asp
For some reason, I simply CAN'T get the example to work. I created the
following two classes, provided with the example:
*-*-**-*-*-*-*-*-*-*-*-*-**-*-*-*-*-CheckBoxColumn

I have set a DataTable and one of the columns I set "AutoIncrement" to True.
I then populate the Table by setting the columns to values then add the row
to the table. I inadverently set the AutoIncrement Columns to different
values but didn't get any errors. Should I be able to set the value of an
AutoIncrement Column? I would have thought it couldn't be done as the column
value was set when a row was added.

Hi all
I have a simple datagrid form which has 4 columns. The first one is used
just like a key and the other threes allow user to enter numbers. The
problem that I am having is that when I click on a cell of a new row but
decide not to enter a value and go back to any of the previous rows for
editting or whatever reason, the value of the new row will be incremented by
value of the AutoIncrementStep
Here is the problem I have

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,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.

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...
