I have a Web service that gets the financial periods and hold a reference to
a disconnected dataset built at initialization. Web methods work on the
dataset inside the web service. Everything is fine so far.
My problem is that when I call a web method to modify the dataset inside the
Web service it is never updated and I get no errors.
currentPeriods method will always give me 1 even if I call ChangeDataset and
call currentPeriods...

When I try to update record, I kept getting this error:
Row cannot be located for updating. Some values may have been changed since
it was last read.
No other users are accessing the database - only 1 user is accessing the
database.
I open the data using adLockOptimistic locking.

Hi all,
I'm trying to update a record in a table with data from text boxes on a
form. As a background to this, I managed to add a new record to the
table in a similar manner with the following:
Set db = CurrentDb
Set rs = db.OpenRecordset("Project Table")
rs.AddNew
rs("Project_Number") = Me!

My experience with databases using C# has been pretty limited thus far.
Mostly I just use a SELECT statement to populate a DataSet, which is
just read-only (mostly for display on a web page), or maybe go so far as
to build an UPDATE or INSERT query with a couple parameters and just
execute it against the database. Currently, this is all done within a
web service, which acts as a kind of protective barrier between the
actual database and...

I have a database table, changes to the data within which I am interested in
acting on. The approach that I'm taking is to have the database update a
file every time data is updated. This process is outside my domain - I can
rely on the file being updated when data changes.
Within my domain is the design of a Windows service to perform the
operations required when the data changes. I have not produced a Windows
service before...

Hi,
I am truing to find a pattern for my Business Logic Layer to be able to work
fine win ObjectDataSource's Update method.
The challenge is ObjectDataSource is not able to work with an update method
that accepts a strongly typed data table as parameters. We have to have an
update method with all data table's columns as its parameter. Like what we
have here: http://asp.net/learn/data-access/tutorial-16-cs.aspx

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,...
