Hi all
I am creating a basic control to perform some tasks, and I want to declare
some events to be raised so they can be handled from the form that the
control is on. I can create my own Event Handler class and use that, but I
would like to use the System.EventArgs class so that my event can be handled
by different controls.
For example:

What advantages do I reap by following the EventArgs pattern in defining
custom event delegates?
For example...
public delegate void CustomEventHandler(object sender, CustomEventArgs e);
public class CustomEventArgs : System.EventArgs
{
int index = 0;
public CustomEventArgs(int Index)

I added the following script to a simple form with a button.
<Script>
public event EventHandler DoThis;
static void Main()

I have a 3rd party object that fires an itemchanged event when someone edits
some data on a form. This event has a custom eventArgs that has a field
called ActionCode. In the code of the event, if you set this ActionCode to
various values the control will respond in various ways (reject, reject
change field, accept, etc). I am trying to understand exactly how that
works as I am trying to extend the control and add more processing s...

Hi,
When we create customEventArgs, we also derive the classes from
eventArgs( ) and I dont understand the advantage of this inheritance.
This is neither an interface nor applied as attribute.
I have seen similar stuff in remoting also where we derive from
marshallByRef object in SAO to create transparent proxy. I don't know
how it creates transparent just by inheriting from base class.

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...
