When trying to update a record in an editable datagrid I ran into a few
problems.
My update procedure is just not working.
Can someone please have a look at my code and see what am I doing wrong.
I had to set the datagrid's DataKeyField to MailSubscriberID manually since
vs does not do it automatically.
Thanks

hi,
when i add a row in a table of a dataset (using dt.rows.add), i expect the
primary key value to be gernarated automatically as i have set it to
Autonumber in access. But instead of generating autonumber, it does not do
anything, which results in null value in the primary key col of new row.
Although remedy to the above is, not to include the primary key in the
selectCommand so that Access does it itself. But i need to include the...

Hi there,
as I am trying to write a recordset class, I am interested in fetching

achieved by using functions like oci_field_name(). But I am not able to
request the information on if the field is primary key or marked as

So, I have this content management system I've developed myself. The
system has a solid community part where members can register and then
participate in forums, write weblogs and a ton of other things.
So, in instances where I list, for example, the latest weblogs. I list
the headline of the weblog, the date and the name of the member who
wrote it.
Now, the name isn't just "Smith", but rather Smith's online status,

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,...
