First off, I apologize if this gets long. I'm simply trying to give you all
enough information to help me out. I'm writing (almost finished, actually),
my first VB.Net application. It's a forms application that is going to be
used to extract data from a legacy system (VSAM based mainframe file
structure), and output data in pipe-delimited record layouts, multiple record
types per file, one file per chosen client. I have been working on...

WebException to retrieve the actual HttpWebResponse object for more
information. The response returned is shown below.
At first I thought this was a...

g++-12 -std=c++20 -Wnarrowing bit_field.cpp

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

Hello
I'm a network technician in training and I need your help.

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...
