Hi List,
I have a question on collection synchronisation. For example I have an
ArrayList called myList and the code is like this:
lock (myList.SyncRoot)
{
// do update on myList
Monitor.PulseAll(myList.SyncRoot);
}

Hi
I often use Queue.Synchronized method to create a queue for multithread writing. I also know I could use SyncRoot and lock to write Queue. Could anyone here please explain to me the pros and cons between those two approaches
Thanks a lo

Hi,
I am converting an existing native C++ program making heavy use of STL
to C#2.0 with STL usage replaced by the new generic collections. The
conversion has gone well to the point where I am replacing an STL map
instance by a System.Collections.Generic.SortedDictionary instance. In
need the collection to be ordered, and to have o(log(n)) look up - that
is fine so far SortedDictionary.TryGetValue does the job. I also need

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,

What is the recommended pattern for implementing a synchronized
(thread-safe) class that inherits from Collection<T>? For example, I want
to implement a SyncRoot property . I do see where I can override
(protected) the methods InsertItem, RemoveItem, ClearItems, and SetItem.
However, I do not see an override for GetItem.
Kindest regards,
Michael

Hi,
I want to create a collection of objects that will be used as a
property of another object. So for example if I had a Customer object,
I would like to have an AddressCollection property within that object.
That AddressCollection property would contain one to many Addresses for
each Customer and the Address object would have properties such as
Street, City, State, etc.
I am struggling with what interface to use to do this. I've...

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...
