Hi everybody,
I need help for this problem:
I'm using a DataGrid to Insert/Modify/Cancel data from a single table.
At the moment, every cell modification of a pre-existing row is correctly
update on the DB.
I have some doubts about inserting a new row.
The table has a Id field that is a primary key defined ad Identity
properties on SQLServer engine.
This column isn't visible on the grid and a properties DefaultValue=0 is
defined.

I have a asp.net page (C#), with a datagrid. I use template for all columns,
and have <asp:requiredfieldvalidator> in with one of the textboxes, to make

leave the field empty. Below please find the code:

Binding Manager & dataset - won't add record
I've got an untyped dataset with controls bound through code. The user
can select a question number from a bound combobox, and the question
number and question text are displayed in bound textboxes. This part
works fine.
When I go to add a new record, the textboxes clear as they should. I
enter a new question number and tab to the textbox for the question
text. At this point, the text for the...

I have filled a datagrid with data from a dataset. The dataset was filled
with a dataadapter - and I used the wizard to create insert, update, delete
commands.
I would like to prevent the user from adding a new record in the datagrid,
but still be able to change/delete data - is this possible??

appropriate row is changed into textboxes. And if user clicks on the
"Update" button, the Update() method is fired. But if...

I create 2 data OleDbDataAdapters, one with the wizard, and one in
code. I know the adapter created in code is OK because I use it to
fill a data table.
However, when I try to use the same SQL insert statement in the two
adapters, the adapter created with the wizard works fine, but the
adapter created in code gives me an error "Object reference not set to
an instance of an object". The code is below. What am I doing wrong?

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:

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.
