ASP.NET 2.0 aspx page with a FormView bound to an ObjectDataSource to view,
add and edit records.
Can anyone point me to a sample of how to retain the user entered control
values when an insert fails?
In other words, when inserting a new record, user enters data in the
controls, but the insert fails.
When the page posts back all the controls are empty or at their default
values.
I would like to retain the user enter values so they can...

Hello,
I am working with a ListView but I suppose that with a GridView might
be the same.
Instead of having an Insert Button on each GridView row I would like
to have only one Insert button, for example, in the GridView footer.
When this button is clicked it should put the GridView in Insert Mode
and the EditTemplate should be showed, maybe (?), in the last GridView

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 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...
