I am working on a generic way to launch multiple similar processes (threads)
at once, but limit the number of threads running at any one time to a number
I set. As I understand it the following line makes a Queue "thread safe", so
I do not need to explicitly lock and unlock it when multiple threads are
working with it.
'Thread safe queue
Private IndexQueue As Queue = Queue.Synchronized(New Queue)

I am trying to use a generic (reflection) IComparer class to sort a
generic list but I get the error:
Unable to cast object of type 'GenericComparer' to type
'System.Collections.Generic.Icomparer `1'
My code looks like the following:
List<AccountDB.Queue> oList = getAllQueuesFunction();
List.Sort(New GenericComparer("QueueName")); <-- Error

OK, I have class A defined as follows:
class A
{
A(Queue<B> queue) { ... }
}
Now, I then have a subclass of both classes A and B. The subclass of A
(SubA), more specifically is passed a Queue<SubB>.

Hi,
Does System.Collections.Generic.Queue not have a Synchronized
method because it is already in effect synchronized, or is the
Synchronized functionality missing from
System.Collections.Generic.Queue? Putting it another way can I
safely replace a
System.Collections.Queue.Synchronized(myUnSynchronizedQueue) with a
System.Collections.Generic.Queue while porting a working 2003 project?
Thanks,

I ran into a problem a while back when attempting to convert existing .NET
1.1 based code to .NET 2.0 using Generic collections rather than Hashtable,
ArrayList, etc.
I ran into an issue because the old code allowed me to do what basically was
the following assignment:
class SomeClass
{
private Queue q;
SomeClass(Queue q)

Hi all,
I would like to make a generic Queue arrry in C# like below.
Queue<int> queue = new Queue<int> ();
But the compiler keep complaining about the part and honestly I don't know
how to make it right.
Can you give me a tip on how to do it?

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...

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...
