I am developing a reuseable data access library for Access, MSSQL, MySQL,
Oracle and etc, for some of other projects.
Initially I build up classes for each database, and a client application is
required to create instance before it can establish the connection and
retrieve data from database.
However, I find in a source sample of Microsoft Data Access Application
Block, which has a NonInheritable class with all the methods in Public
Shared. So the client application can just retrieve the data by calling
directly the static class methods.
I start to think that my original approach may not be as good as the sample
by Microsoft, can anyone tell which one is better?
Thanks

I am trying to add some code to below to include a datatable and fill the
datatable. The reason for doing this is so as I can check to see whether
there are any rows returned by the stored procedure. If there are no records
returned then this would give me an indicator and I can re-direct the page
somewhere more appropriate. Well this is the theory. I have never used
datatables before and am not sure how to implemenet what I want so I was...

Hello,
I have a multithreaded windows NT service application (vb.net 2003) that I
am working on (my first one), which reads a message queue and creates
multiple threads to perform the processing for long running reports. When
the processing is complete it uses crystal reports to load a template file,
populate it, and then export it to a PDF.
It works fine so far....

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,...
