I'm trying to load an xml file into a dataset, then load the same xml
file with a slight change into a second dataset, then do a merge to
see what changed between datasets.

We converted our app from 1.1 to 2 and some code was no longer working.
The case: From a non typed datatable, convert it to a typed one.
How to reproduce the bug:
-------------------------------
1) Create a project.
2) Add a new Dataset (keep DataSet1).
a) Add a new DataTable (Keep DataTable1)
b) Add a new DataColumn (Keep DataColumn1)
3) Add a new Window form.

Hi there,
Can anyone explain the following (very) simple scenario.
1) I make an exact copy of my "DataSet" and delete one record from a given
table (in the copy)
2) I invoke "DataSet.GetChanges()" on the above copy and pass the results to
"DataSet.Merge()" on the original copy
3) If I now inspect the original copy, it shows that the record has *not*
been deleted from the table. However, a call to "GetChanges()" does show my

Hello all,
Here is my problem:
I am trying to merge 2 datasets but I don't want to overwrite rows
that are already modified in my working dataset.

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:

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,...
