Hi there,
How can I iterate through collections starting not from the first item but
from an offset?
I need to check if a dataset contains records that have some field values
that can conflict with some other records. So my code would be like the
following:
MyDataSet copyDataSet = new MyDataSet();
copyDataSet = myDataSet.Copy();

Hi
I have an application for my company's HR department where we store
resumes for candidates we receive. I have an application that uses
VB.Net and ADO.Net and data bindings (through code) to controls on a
Windows form. The question I have is that once the database grows and
contains a large number of records, I am worried the dataset is going
to create too much overhead when the user clicks "show all records"
(the full resume which...

OK, here's my setup. I have a treeview control that is populated with
records from a Product table, and it allows "checking". This is used for my
automatic notification system. Say a particular Product is sold, any users
who have that boxed checked will get a notification. So my (shortened)
database layout is as such:
Product Table
ProductID (PK)
ProductName

I'm using the following subroutine. The two different XML files are
identical with the exception of three additional records in the second
one. One has 450 records, and the other has 453. After merging, I get
903 records. I guess what I expected was 3 records; just the
differences in the two.
The two tables have the exact same structure, etc....
So am I misinterpreting how to do this? It seems to me that the merge
should produce only...

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,...
