Hi,
I use a DataView to display a State field. But some rows have the same state
like 'OH'. How can I just display only one of them like SQL's DISTINCT? Can I
use .rowfilter? How?
I don't have to use DataView. If DataTable can do it, it's ok too.
Thanks in advance.

Hi,
Has any one ever compared the performance of calling a DataTable's
Select method with a stored procedure doing the same thing?
My point is:
dataRows = DataTable.Select(filter) is better or
Passing paramters to stored procedure?
The datatable holds about 500-700 rows at any given time.
If I select one of the approaches the business logic will go into
respective layers.With dotnet in picture what would be a good approach

I'm trying to find a way to keep from having to fill a DataView after
every PostBack to a page. Basically, the design is that I have a
DataView that I fill, which I then set as the DataSource to a DataGrid
on my page. This works well, however, like I said, I would like to
keep from having to fill the DataView on each PostBack. So, naturally,
what I did was checked whether or not the request was a PostBack by
checking the IsPostBack...

I have a code that returns data in IList. My webGrid doesn't allow me to
sort with IList returned, it say it only suports DataView, DataTable and
DataSet, not IEnumerable. I don't know how to return the DataSet type when
using the following code:

namespace WareHouse.DataLayer.DataObjects

I have several columns which I've sorted but the Date Field sorts as a string
rather than as a date and I can't seem to figure out how to fix that.
Below is my code.
Thanks for your help.

I have a Datagrid that is bound to a Datatable at runtime. I allow the
user to select a number of rows using the mouse and then click a button
that says "check selected rows", which then cycles through the selected
rows and sets a check box field in the datagrid (and thus the databound
datatable) to checked/true. It works like this:
Dim cel As DataGridViewCheckBoxCell
For Each row In DataGrid.SelectedRows
cel = row.Cells(0)
cel.Value =...

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:

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,...
