If I have multiple threads running a Sub as below then a number of threads
can be held up at the SyncLock. When it becomes free which thread goes
first. Is it just by chance which thread goes first or do the threads queue
in a FIFO or perhaps a LIFO bases.
Thanks

Ok, I have done a lot of reading(of the newsgroup answers, help files and
MSDN articles) of synclock.
I understand what you are saying in the newsgroup, and it is very helpful.
It does, however, directly contradict what the VS 2003 help file says, and
it seems that various posters to my original questions on Synclock disagree
with each other. It seems, that the best practice is to use sysnlock to
protect code, not variables. That...

Hey,
I have about 5 Shared variables, that I want to be locked for access when
they are written to.
I'v read in the MSDN about the SyncLock statement, and I'm prety sure that's
what I'm looking for,
But the SycLock statement requires a statement in it's decleration:
SyncLock <Statement>
MySharedMember=NewValue
End SyncLock
What the statement's supposed to be?

Specifically, I don't understand the parameter that Synclock accepts. How
is a reference type a lockable entity? What -is- a reference type? Is it a
number? Is it a value at a specific memory location? Does synclocking a
reference type put an entry in a catalog somewhere in the system, and it's
removed on the "end synclock" statement? Are there any guidelines for
creating synclock objects?
I've found a surprisingly small amount of...

Hi all,
I am trying to develop a Producer thread that listens for UDP packets on a
socket and store then in an ArrayList.
The consumer should read data from list and block when no element is in
list.
When producer inserts a message in list, it should make the consumer aware
of the item and consumer should process the item as soon as it is available.

I have a buffer that needs to be locked sometimes, because 2 processes
update it.
So I made the buffer into a class and whenever there is code that
affects it, I sandwich the code between

End Synclock
My question is, what is Synlock protecting? Is it just protecting

I have tested that using locks for sinchronize calls to a web service
does not work correctly. Surely I am doing something wrong.
I have a "global" object for the "semaphore":
public object oLockOfWebService = new object();
And we have two concurrent libraries (one in c# and another in vb.net)
that realize calls to a webservice with this code:

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...
