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...

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

Hi, I have a COM control / server I'm trying to get events from in my c#
applications.
1) I'm trying to get events in both c# console apps and in c# winform apps.
2) I can call methods on the COM control / server ok, I just don't receive
any events. The method calls are definitely successful.
3) I have got events and communicated ok with other COM controls from c# -
it's just this one I have a problem with.

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?

What are reasons to create your own events? Why not just call a class
method/function instead?

Hi all!
Sorry for the cross-post, I really have a difficult problem and need
some help badly.
I have a VB6 ActiveX component (dll) that listens to a real-time data
feed of stock quotes (built in an OCX) and then passes them on using
events.
The consumer of these VB6 events is a C# dll using .NET 2.0

I am involved with development of a Portal solution using ASP.NET 2.0
and WebParts. The WebParts framework use the default personalization

Everything works like a charm, with the following exception:

Hi everyone,
I've got a strange one here. There are two datagrids on my page, one nested
within the other. I'll refer to them as the topmost and secondary
datagrids.
In the topmost datagrid's OnItemDataBound() method we check for the row in
which it's appropriate to add the secondary datagrid. Exactly one row in
the topmost grid will contain the secondary grid.

Hello:
Is there a way to prevent one event from firing while another event is
already being fired?
I have a tool that extracts media from web pages and it has multiple
events firing when the status of the download changes.
Some of the events are used to tell the next file to download while
others manager other resources. However, on occasion, one event will

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.
Here is my compilation command:
