Hi,
I need to display columns in a data grid based on 7 different queries. Now I
have 32 questions:
1. Is it possble to have 1 single data adapter with 7 queries & 1 data set
or do I need to have a separate data adapter & a separate data set for each
select query?
If thats possible then how?

When you bind a text box to a field that contains null values the text box
displays an empty string. Great!

NULL value. However the EndEdit event on the datarow returns the error The
input string was in an incorrect format
I have failed to find a way to either trap the empty string in the
rowchanging event and turn it into DBNULL or to programatically...

Hello,
I made a windows form with a combo box and 4 text boxes. All 5 objects should get their data from a data set which is populated
in the form load method. The combo box has item ids. When the users selects an item from the combo box I'd like the 4 text boxes to
get populated with the corresponding item information from the same dataset table row that the combo box is pulling it's info from.
Is there an easy way of doing this besides...

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
