Hi everyone,
Here is my problem:
I have the following classes:
- DataNode - this class is designed to hold some data and will be contained
in a tree like data structure DataTree. When DataNode is changed, it raises
"Changed" event. The class has a reference to the DataNode it is being
contained in:
- DataTree - tree like data structure that contains DataNodes; When

Hi!
How can I unregister all the events registered to a control?
I have seen a piece of code in another thread, which gets all the registered
handlers for a specific event.
Let's say I have a CustomTextBox : TextBox, which has quite a lot of
events...
Do I put unregistering code for all the possible events in the Dispose
method? Or is there another way?

Hi
I use the following syntax to have events inherited from base to child classes which works nicely (virtual and override keyword on events). But I am wondering if it is a "supported" way of using events since I never saw it used anywhere in MSDN documentation/samples?! Or it will just break when I upgrade to .NET Framework 2.x in the coming years
namespace MyNamespac
public delegate void MyDel()
public class MyBase
public virtual...

I have the following code, which appears to be working. However it doesn't
look right. The part I am wondering about is the logic in
DisconnectEvents(). This logic creates a new delegate and then expects to
find that delegate in the list of event handlers.
What is the proper way of writing this?
Regards,
Bob Rundle

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.
Thank you

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?

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 ?

Hi,
Here I mean "User" in the Programmer or Javascript sense. I merely wish to
programmatically trigger an Event. It would be absolutely fantastic if there
was a (Form level?) ONUSEREVENT() and a setEvent() function but, in the
absence of this, is it not possible to use DOM to change an object's
properties resulting in a state-change event?
I have tried with ONCHANGE() and that only seems to work if the
"interactive" user changes the...
