If I fill my dataset and there is no data. The dataset is still created
with zero rows (all columns are there). When I add my first row using
the script below, it takes over 2 seconds to add??? If I add the second
row, instant.
How can I eliminate this delay?

I have built a control that runs an on-line help system. Depending on the
category you selected via dropdownlist, it goes out and gets the child
subcategories, and if there are any, adds a new dropdownlist to the screen
for selection. This continues until there are no children, and then it
checks for a help article list based on that last selection and displays
actual articles for display.
Adding the controls and getting everything...

Trying to figure out the technique which should be used
to add rows to a datagrid. I am thinking that I would
want an "Add" button on the footer, but I am not quite
sure how to do that. Is that the best method? Do you
have a sample of how to do this?

Hi all,
I know this is easy, just can't seem to get it. I have a windows form, and
a text box, with a value already in it. I need to add that value to a table.
It's just one value, so the entire row doesn't get filled. I have a
connection and all that stuff.

System.EventArgs) Handles btnPlaceBet.Click

I am adding a new record to a table via a dataset/adapter.
I have got the following to work for me but I am wondering if there is
a better way to do this.
I am having to have something in my DS before I can add records, since
DS does not exist. I'd rather not have a SELECT since I really don't
need any records in my dataset that I will be adding a new record to.

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
