Hi, I am trying to use a data grid in a web application in which I have
three tiers. The DataGrid is not set up to a data source, or a data adapter,
so everytime I make a change I send the cell information to another object
which forms an SQL query and makes the query to the DB (actually to a
DBFacade object). In any case, please see the code I have listed below for
my update DataGrid event. With this code, the DB is updated using the old...

..NET Framework Class Library for DATATABLE (see below) I get an error on line
3 that says "Type expected". Is something missing from the code?

Hi
I'm hoping somebody can help me with the following problem that has occurred
to me.
Suppose I have two tables in an SQL Server database. Let's call these tables
A and B. Assume that A has two fields: a primary key and another holding a
string. In table B there are three fields: a primary key, a foreign key
(which links to the primary key in A) and other field holding a string.

In an application I am writing the user can define a series of
steps to be followed. I save them in a sql database using the
field "order" (a smallint) as the primary key.
(there are in the range of 20 steps)
On the admin page the steps are listed, in "order" order and the
user can create new steps and assign an order and all is well.
The problem may come in using a renumber function which should
take the steps in their current order...

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,...
