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:

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?

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'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 ?

I have an application that needs to perform some background work, i.e.
Logging, wich must not block the main thread. How would I basically
design such a scenario? It is obvious that I should do that on an extra
thread but I think it is a bad idea to spawn a new thread everytime a
log-message is written and let it die once the message was written. But
how do I keep a thread alive and trigger the log-messages and pass the
string to that...

I have put together this article to give people starting Swing an awareness of issues that need to be considered when creating a Swing application. Most of the Swing tutorials that I have seen just help people display some nice widgets quickly without explaining some issues that need to be tackled when a full application needs to be developed. This article does not go into full implementation details because those can be found by reading the...

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...
