How can I pass, by ref or out parameter values when calling DynamicInvoke
Method.
e.g. Here is my Delegate:
public delegate int BinaryOp(int x, int y, out double z, ref bool overflow);
Here is how I am creating a delegate object for "Subtract" method.
BinaryOp op2 = (BinaryOp) Delegate.CreateDelegate(dt, tt,"Subtract");
Here is how I am creating parameters object. Notice t and ret are

Hi,
I used to use the following code to play sound in VB6:
Public Declare Function sndPlaySound32 Lib "winmm.dll" Alias "sndPlaySoundA"

Greetings,
I am trying to understand the rational for Raising Events
instead of just calling a sub. Could someone explain the
difference between the following 2 scenarios? Why would I
want to raise an event instead of just calling the sub?
Scenario1 -- Using Events

I have an ASP.NET application in which I would like to call my button click
event (imgSubmitSearch_Click) on the page load if certain criteria are met.
Is this possible?
What is the correct syntax to be able to programmatically have my
imgSubmitSearch button clicked? I tried the obvious, Call imgSubmitSearch,
but intellisense doesn't like that due to the sender / e arguments.
Private Sub imgSubmitSearch_Click(ByVal sender As...

Jon Skeet wrote in the .NET general newsgroup 11/17/2005:
"The difference between Invoke and DynamicInvoke is that the parameters
to Invoke depend on the delegate itself - the method has the same
signature as the delegate. DynamicInvoke has a "fixed" signature, and
it dynamically calls Invoke with the appropriate parameters."
So far I have seen DynamicInvoke only used in conjunction with generics
event arguments. Is there any other...

I've just discovered DynamicInvoke methods while reading Jon's
threading article. And my question is how it's different from a
regular invoke method?
In this method:
/// <summary>
/// Invokes the wrapped delegate synchronously
/// </summary>
static void InvokeWrappedDelegate (Delegate d, object args)

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...
