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.

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...

receiving a "Specified cast is not valid" error that has something to do w/
the keys involved. The stack trace is:

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

Hi All,
I am using a combination of LINQ to SQL and bulk insert. In the
process of performing 'one unit of work' I will be doing things like
reading, and deleting records using LINQ to SQL and then inserting new
records using bulk insert.
One problem I am having is trying to use a 'transaction' to wrap
around the whole thing.

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,...

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...
