I have a small Window application and through out the different forms I
create a different dataset. At the begining I used the Tools to drag and
drop the SqlDataAdapter, connection and dataset objects to the frist few
forms but then later I removed those and created these objects in my code.
I now see 3 datasets in the Solution Explorer panel part but not all the
datasets that I have in my codes. Are these 3 datasets leftover from the...

Quite awile ago I posted to this newsgroup in regards to using Datasets in
my VB 2005 application. About how many Datasets should be used.. a limit to
the number of tables that should be included in a dataset, etc. The
concensus I was given was that one Dataset should be created per logical set
of data, or approximately 1 Dataset per form (usually consisting of 5 or
less tables).
After finishing 2 projects using VB 2005 and DataSets I...

Hi all,
I'm having a baffling problem with a windows service that I'm working on.
Basically, I am using a typed dataset to insert a large number of rows
into an SQL Server 2005 database. But there's a memory leak that seems
to be to do with calling the data adapters update method. It's making
the memory usage go through the roof and ultimately the service crashes
after running out of memory.

U had to display username , first name, last name in default.aspx page after login.

I'm trying to decide if it is better to use typed datasets or business
objects, so I would appreciate any thoughts from someone with more
experience.
When I use a business object to populate a gridview, for example, I loop
through a datareader, populating an array list with instances of a custom
class in the middle tier, and then send the array list up to the
presentation layer and bind the gridview to it.
If I use a typed dataset, I...

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...
