Hi all,
In a web form I use a for loop to dynamically add TextBox'es to a page
(one for each item in an input file). I can get the input values and I
can display them in Label's and TextBox'es. That part works. However,
my problem is that the form lets the user choose from input files; the
labels are updated, the textboxes are not. This seems to me like it is
a ViewState issue, I just can't figure out how to fix that...
Apparently the...

Hi,
here's my problem in short: Text boxes in gridview don't seem to hold
their value if the column's .Visible property is changed back and
forth.
I've got a form with a gridview populated from a data view (which in
turn is loaded from a manually setup DataTable for testing purposes).
One of the columns in the grid is a checkbox that's tied to an event
handler that'll change the .Visible property of a column with a text
box. That text...

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.

Now, this would greatly impact the work of software developers. The idea...
