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,
I'm trying to add a where clause to my query:
List<stringtypes = new List<string>();
types.Add( "A" );
types.Add( "B" );
query = query.Where( c =types.Contains( c.Type ) );

Hello everyone,
I have a c# project with a sql server database.
I have a number of lookup tables in my database which I successfully managed
to import into my LINQ dataclasses.
eg.
Table: tlkpColor
(PK) tlkpColorID

I'm encountering some strange behavior after deploying a ASP.net 3.5 website
to production, i'm unable to reproduce these in my dev environment. This
error seems to occur very randomly but it's occuring enough to be a real
cause for concern. The errors occur a couple times a week and the website is
hit with constant traffic 24x7. Below are the two errors that are
encountered. I had read something about MARS causing errors like this but...

I'm not getting the theory behind LINQ, and without that I can't get
my head around how to use it and why.
Here's what I _think_ I'm trying to do:
I've got a menu with several items. Some other part of the application
is changing the text in a combobox and I want to set the indicator to
the correct menuitem. I can loop through the Items collection and look
at the Tag for my indicator, like so:

We’re storing our main entity in an insert only table which stores the
history of past revisions, but we’re facing problems with storing this
history as LINQ will only update the entity, and not reinsert it with a
different revision number.
Compounding the issue, we’ve also got an associated table storing properties
for our entities which is not revisioned, but we still want changes to the
children of our entity (additions, changes...

Hi Tim
I am not a LINQ expert just a LINQ user and (was a little envious why the langauge i fantasize doesnt have it (pardon my ignorance of python))
LINQ as far as i know allows you to query all sources using a consistent interface .
You can query a message queue ,xml document ,array object or relational source by learning LINQ and even join them as illustrated below

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...

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,...

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...
