The below is some test code to help me learn how to update a dataset.
It is supposed to read the value of UserCounter and write it back.
The UserCounter is being read correctly as 0, is 1 when written back, but is
not being written back to the database.
Although I've used a foreach loop there is actually only 1 record in the
dataset.
I'm going to eventually use transactions but have commented them out for now

I need some sample code showing how to manipulate data in my access database
using C#. This is what Im trying to do:
Dropdownlist with datagrid both bound to datasource. When the drop down list
value changes - the datagrid values change accordingly. I managed to get
this working by setting the currencymanager to the dropdownlist
selectedIndex (which is probably the wrong way to do it, bu the datagrid
seems to update its values correctly)...

I am using VB.NET 2003, SQL 2000, and SqlDataAdapter.
For every record in tblA where colB = 'abc', I want to update the value in
colA.
In VB6, using ADO I can loop thru the recordset,set the values of colA and
call the Update method.
How can I do this in VB.NET and SqlDataAdapter ? Thank you.

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,...
