Hi,
I'm working on a project which includes WebServices and Windows Form
application.
The Windows Form application will call the WebServices to retrieve data from
database. The data will be returned as DataSet.
Now, here's the problem. On .NET Framework 1.1, if any rows in the dataset
returned contain errors (marked by calling the SetColumnError() method or

I'm implementing paging through search results using cursors. Is there a
better way to know total number of rows under a cursor than running a
separate COUNT(*) query? I think PostgreSQL is bound to know this number
after the first FETCH, isn't it?
On a side note, why queries using LIMIT are SO terribly slow, compared to
cursors and sometimes even ones without LIMIT? Shouldn't LIMIT be internally
implemented using cursor mechanism then?...

This is a very simple DB2 SQLJ stored procedure. The problem is that it
seems to run fine but returns NOTHING. I mean..as if nothing has
happened..not resultset is returned. I am passing value 'D11' to :workdept
and I have checked in the table that 6 rows should have returned. Any
ideas why no resultset is being returned.

I have a DataTable that I'm binding to a DataList control on my web page. I
want to be able to restrict the number of rows that are initially displayed
from the DataTable. For example I want to be able to show the first 5 rows,
a button will then allow the user to 'show all records'.
Although I've used a DataView before, I am unsure how this can be of use
when I need to restrict the number of rows. I am aware of the RowFilter
property,...

I have a CustomDataGrid that inherits DataGrid. I use the filter below
via a context menu, which works fine.
( ( DataTable ) this.DataSource ).DefaultView.RowFilter =
filterexpress;
The above gives me narrowed results via a right click on a grid cell.
I filter on the cell value. I'd like to click another cell and filter
again. For example, I start with 100 rows. I filter as above and get
50 rows. Now I want to filter on another...

I have an ASP/ADO application querying an SQL Server DB. I want know the
most efficient way to determine if more than one row is returned from a
query. If more than one row is returned, the user will be presented with a
choice of which row to process. If only one row is returned, I want to skip
this stage, and process that single row immediately.
I can think of a number of ways of acheiving this (eg. .recordcount) but I'm
looking for the...

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:

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,...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
