I've been playing around trying to bind textbox controls and datagrids
to typed datasets. Up until recently, I never used DataBindings. I
always manually wrote the value into a textbox and stored its value
after the textbox lost focus or whenever someone manually saved the
record. I came to the conclusion after a long time and after many apps
have been developed that there had to be a better way. What I thought
would have been great is...

I'm writing what should be a very simple app against an Oracle database. The
app has a number of user controls, any one of which is loaded into a main
display page using the loadControl method, depending on which menu item a
user selects. Each of these controls follows the same basic pattern: Get a
dataset from the database and then display the results using basic
databinding.
Everything works fine except that I'll occaisionally get an...

Hi everyone,
I have a ComboBox that when changed, calls a method to change the content of
a ListBox.
I'm also using the Listbox's SelectedIndexChanged event to change other
control values on the form.
(It's a Company -> People -> Personal Data relationship)
When I bind my datasource to the ListBox, I find that the

I need some sample code showing how to manipulate data in my access database
using C#. This is what Im trying to do:
Dropdownlist with datagrid both bound to datasource. When the drop down list
value changes - the datagrid values change accordingly. I managed to get
this working by setting the currencymanager to the dropdownlist
selectedIndex (which is probably the wrong way to do it, bu the datagrid
seems to update its values correctly)...

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,...
