Marty,
The way I understand it Events are to Delegate fields that Properties are to
other fields.
The event encapsulates & protects the underlying delegate value.
Chris Sells' book "Windows Forms Programming in C#" from Addison Wesley has
a chapter explaining the relationship. The story is also available on Code
Project: http://www.thecodeproject.com/csharp...te_bedtime.asp
Hope this helps

Marty,
I just found the story on Chris Sells web site itself, where I was
originally looking for it. http://www.sellsbrothers.com/writing...=delegates.htm
Same story, different location & formatting.
Hope this helps

The garbage handler in the .NET framework is handy. When objects fall out of
scope, they are automatically destroyed, and the programmer doesn't have to
worry about deallocating the memory space for those objects. In fact, all
the programmer has to worry about is the total sum of objects loaded into
RAM at any known point. Memory leaks are not a problem.
.... So one would like to think. The reality is that delegates and event...

Hello!
I am still transitioning from VB.NET to C#. I undertand the basic concepts
of Delegates, more so of Events and somewhat understand AsyncCallback
methods. But I need some clarification on when to use one over another? If
anyone could provide any additional info, your comments, best practices, any
good articles, specific examples, etc.

Hello,
I'm studying a book on VB.net Win apps, and I'm reading a section on
events and delegates and raising events.
Is it just me, or is this not just subs dressed up as something else?
I mean, for one, delegates point to subs, so when you call a delegate,
why not just call the sub dierectly and not bother adding the extra
code involved adding the delegate?

There are a set of clients who need to be notified of certain events. I have
used events and delegates (publisher-Subscriber model) for the
notification mechanism. All the clients register with the event publisher
and subscribe for the events that they are interested in. When a certain
event happens, the subscribers are notified about it.
I want the clients to return a value after their callback method is called.
If any of the client...

Hi,
I am new to C# (with long year experience in C++) and I am a bit confused by
the language construct of events. What is it I can do with events that I
cannot do with delegates? At the moment it seems to me that Microsoft has
developed similar functionality via two keywords. I do understand that an
event offers better encapsulation as the underlying delegate is private, but
is that all ?

I understand delegates (static and non-static) and I agree they are
very useful, and that the "Forms" used in the Windows .NET API could
not work without them. That said, I'm curious as to how many heavy
duty pro programmers in this newsgroup have actually used a delegate
in their code, say in the last year of coding. By "use" I mean
constructed a delegate and using it in an Event Source class and an
Event Receiver class.

There is another example on page 124 that shows how to use delegates to sort

I don't understand the difference between events and delegates. Are they
redundant features? How do I decide which to use?

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
