Hi, can someone please explain to me how a static member of a class works.
For example if I have:
public Class1
public static Class2 myClass2 = new Class2;
public static Int16 thisValue = 200;
public static string thisString = "This string value";
public static boolean thisBool = True
....
if Class1 is never instantiated what value do these variables take on and

Hi,
I'm new to .NET and have a question about the use of static variables vs.
session variables in a web form in C#.
Instead of using a session variable to hold a string to persist during
datagrid paging. Can I use a static variable? Also, if I use a static
variable is that variable shared by everyone that brings up the aspx page?
Ex, if 4 people are viewing the aspx page is an instance of the static
variable created for each of the...

I'm working on a class library in .net, and am having a problem that I
can only describe as a memory leak (which garbage collection was
supposed to eliminate). My class library contains a single class, one
member of which is a static SortedList of session data objects. One
of my methods creates a new object on this list, and another removes
the item from the list, which should make it eligible for garbage
collection. I've tested this in...

Hi
I have an ASP app which references a few static properties in some of the
classes. I understand that you should use Session variables, but is it
"possible" to have each session "not" reference the same static members.
For example if I update the static member on one session this change will be
reflected on somebody elses session, which I don't want.
I hope there's an easy solution for this as changing to session variables

Hi
I am considering storing my session variables within one static object
with session scope. The static object will be a class with accessor
functions to get and set the equivalent session variables stored as
member variables. This will allow strong typing. Apart from the
problems of multithreading, are there any performance overheards of
which I should be aware?
Thanks

I have found it very easy to have a Helper class that has static
members which access Session Variables. For example:
public class HelperClass
{
public static doCustomer CurrentCustomer
{
get
{
if(HttpContext.Current.Session == null)

Hello everyone,
I have a Packet class I use to send packets over the Internet. All the
packets sent in a session are supposed to share a common random ID.
I figured I'd use a static const member inside my class.
class Packet
{
static const int session_id;

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...

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...
