I've always been taught that stored procedures are better than writing SQL
in client code for a number of reasons:
- runs faster as is compiled and lives on the database server
- is the more proper tier to put it since is a data function
But then I've heard that writing SQL in my client .NET code might run just
as fast? Dynamic SQL or something?
And then there's LINQ on the horizon. Is it a successor to everything

Hello guys,
I am creating a LINQ (to DataSet) query where I need to do something
like...
DataTable _TableNumberX = dtsMyDataSet.Tables;//this line OK
IEnumerable<DataRowrsResultSet =
from TableNumber in _TableNumberX.AsEnumerable()
select TableNumber;

Hi all:
after reading different places/sites about linq... I ran into these questions:
1. What framework do we need to run linq ?
(does it depend on what version of visual studio we have?)
how about vs2008?
is it different name space or framework for linq xml or linq sql? (
2. do we need to have references to what linq's dlls. or namespaces?
system core?
3. what name spaces are needed?

LINQ to SQL or NHibernate?
Thanks in advance,

Hi all
Having a mental block with linq!
I have a simple aspx page with a button and a label. When the button is
clicked I want the label to display the result of a simple query:
i.e. Select name from MyTable where id = 1
This should return ‘peter’ - simplicity using sql
I'm trying to do this with linq and getting nowhere (converting to string
error)

I'm attempting to use LINQ to insert a record into a child table and I'm
receiving a "Specified cast is not valid" error that has something to do w/
the keys involved. The stack trace is:
======================
Message: Specified cast is not valid.
Type: System.InvalidCastException

Hello!
I have the code below. In the previous code not shown below I have used linq
to extract some row and
these have been placed in the var variable result. In my code there is just
one entry in result but it can be more.
All works fine the first time I enter the following foreach loop
foreach(var o in result)
{
o.ID = nextParamID.ToString();

I am a bit conservative type and usually give some time for technology to
mature before starting to try it.
Today my question is Linq. To start using it or not.
So here is the voting questions.
1. It speeds up development. Yes or No?
2. It makes programs easier to code and read. Yes or No?
3. Perfomance is the same (or comparable) comparing Linq with MsSql and
ADO.NET

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,...

Hello
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...
