My question concerns the documentation for Control.BeginInvoke(). At one
point is says:
"Executes the specified delegate asynchronously with the specified
arguments, on the thread that the control's underlying handle was created
on."
later in that same documentation page it says...

Is The following Code valid it is like a mini thread pool(a friend at
work wrote it)?
I have cut down the code a bit but kept the essential parts.
The main part that I am would like explainedis when the async callback
gets called and the the line
m_WaitCallback.EndInvoke(AsyncResult);
How does it know which method has ended. i.e. does the AsyncResult
identify it?? Is it accepable to have one member variable used for all

Hi guys 'n' girls,
I want to use callback methods when using BeginInvoke on some events. So far
no problem, but know I thought about what could happen (if I'm not completly
wrong).
Lets say an event is triggerd with BeginInvoke and a callback funktion which
is part of the instanze which is also holding the event. So the call looks
something like this:
public class MyClass {

I'm not entirely sure what the difference is between these two approaches.
In order to avoid reentrant code, I was using Control.BeginInvoke in my UI
to cause an asynchronous activity to be done on the UI's message loop. I
began to get System.ExecutionEngineException errors so (on the theory of do
something different if what you're doing isn't working) I switched to using
delegate.BeginInvoke with the appropriate EndInvoke and the problem...

Hi,
I've omitted a large chunk of the code for clarity but the loop below is how
I'm calling a delegate function asynchronously. After I start the each call
I'm incrementing a counter and then making the main thread sleep until the
counter gets back to zero. The call back function for each call decrements
the counter. Is there a better way to make the thread wait until all calls
are complete besides using the counter? I've seen some things...

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:

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,...

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...
