Hi,
I'm getting some strange results using the autoincrement column on my
datatable. I'm populating a datatable with data from my database and
displaying this in a datagrid. The first time I get the data from the
database I create a new table with an autoincrement column bind the datagrid
to this new table. The auto increment column is displayed as an ID col in the
datagrid. The user can add records or modify records at this point, when...

I have set a DataTable and one of the columns I set "AutoIncrement" to True.
I then populate the Table by setting the columns to values then add the row
to the table. I inadverently set the AutoIncrement Columns to different
values but didn't get any errors. Should I be able to set the value of an
AutoIncrement Column? I would have thought it couldn't be done as the column
value was set when a row was added.

Hi all
I have a simple datagrid form which has 4 columns. The first one is used
just like a key and the other threes allow user to enter numbers. The
problem that I am having is that when I click on a cell of a new row but
decide not to enter a value and go back to any of the previous rows for
editting or whatever reason, the value of the new row will be incremented by
value of the AutoIncrementStep
Here is the problem I have

For some bizarre reason, each time I insert or update a row in my table
`image`, the field value for "image_width" is fixed at 127, no matter
what value I use!
Here is the schema:

Hello All, I could use some help on an error that is just now popping it's
head up.
Seems that the autoincrement numeric has hit 32,767. The autoincrement is
used in various locations in the database, but in this case (log sheets), we
have hit 32k log entries over the past 2 years.
Is there a simple switch to set the autoincrement from integer to long
integer?

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...

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,...
