Hi Experts,
I am doing a prototype of providing data access (read, write & search)
through Web Service. We observed that the data storing in SQL Server 2005,
the memory size is always within 250MB. Our aim is to support ~50K
concurrency users.
After investigation, we are thinking to use In-memory database for achieving

I want to develop a datagridview allowing column selection and filtering,
like this:
http://www.codeproject.com/KB/grid/GridFilter.aspx
This example is using dataset. My question is if:
a) I use the same way, using dataset
b) I use Linq converting a query to dataset
c) or if would be done just with Linq

Can I use LINQ in VB .Net 2008 to get to a Visual FoxPro Table? I've
seen demos of it with SQL Server but they've used it with a server
browser and I don't think that'd work when I need to see VFP tables.

Hi all,
I am having some problems using LINQ to access Distinct records from a Dataset. I have looked around and believe it should be as simple as added .Distinct() to my LINQ query below, though intellisense doesn't even give that option!
My DataSet has multiple tables, all populated with data. I have a table called DemographicCriteria which has the fields listed below.
CriteriaID
DemographicCode
InputID

Hi
I'm having some problems getting a dynamic LINQ query to work on my DataSet. The idea is that a user selects certain criteria, and then the LINQ query filters through the dataset making the requested changes.
The table I am trying to alter is called RawData, this is defined in a DataSet but has no data columns as these aren't known until some data is imported. As part of my import routine it automatically creates the correct columns...

I was just wondering, when you create dataContext methods, should you put
business logic there to try and minimize pushing data through 2-3 layers of
code? or should the business logic still go in another class somewhere
making it access the dataContext methods?

Hi...
I have an sql server 2005 database that has a table called TestXml in it.
The table has the columns ID (identity, int) and MyXml(xml). I created a
stored proc on the server to insert a row into the table. It looks like
this:
create procedure InsertRow(@xmlDocument xml)
as
insert into TestXml values(@xmlDocument);

I have SQL SERVER 2008 Express and C# Express 2008 - both sp1.
I can remove and update data in my database only thru direct SQL query thru
database explorer,
but quite unable to do it through dataset and linq.
Thanks in advance

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
