Back when the new J2SE1.5 features were announced, there was a
JavaLive community chat
(http://java.sun.com/developer/community/chat/JavaLive/2003/jl0729.html)
in which Neal Gafter explains the Sun stance on lack of support for
delegates:

I’m just starting to learn delegates. I’m at the very beginning. If I understand correctly, delegates are for when you want to pass a function as a parameter. For example the client provides a custom function to be called in a provider class. My confusion is that you can already achieve this by interfaces and objects without delegates (which...

I am trying to understand Delegates and where/when to use them.
I can see one potential use of a delegate (on form closing, set the cancel
property in the event arguments.)
Does anyone have a link to a site that describes delegates using VB.Net in a
manner that doesn't require rocket science to become enlightened.
TIA

Hi All,
I recently worked on delegates. But I have a question regarding
Multicast delegates. The scenario is as follows:
I have a delegate myDelegate with object dlgt, and two methods
myMethod1(), and myMethod2().
Using multicast delegates definition I can write as follows to add the
two methods to my multicast delegate:

I am looking to make something like a delegate that i can use in my
projects but am having a hard time getting started.
The behavior I am most interested in is how a delegate changes it's
Invoke method dynamically to match the arguments supplied to it when it
is defined. For example...
public delegate void MyDelegate(string myString,...

My question is regarding the use of delegates in C#. I see how .Net uses
delegates to wire event handlers to events. It’s an object created by a
single line of code by the system and that makes perfect sense to me. I
understand that there is a lot of code underneath that the system has created
that makes it all work, thereby making it...

I'm studying the book "Microsoft Visual Basic.NET Language Reference" and I
would like some clarify the difference between events and delegates. On page
156 I see a WinForms example of timer that uses the "WithEvents" and events.
There is another example on page 124 that shows how to use delegates to sort
an array.
I don't understand the...

They usually don't teach you in most textbooks I've seen that
delegates can be used to call class methods from classes that are
'unaware' of the delegate, so long as the class has the same signature
for the method (i.e., as below, int Square (int)).
Here is an example to show that feature. Note class "UnAwareClass"
has its methods Square...

Hello all—
I’m trying to get the below to work and cannot get the format right.
It’s from this example: http://msdn.microsoft.com/en-us/library/8627sbea(VS.71).aspx
What it is: I’m trying to store multicast delegates in a hash table,
and then fire the delegates one of two ways (after registering/
creating the delegates, etc).

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. ...
