I have a class which inherits from CollectionBase. My version adds events to
notify client whenever items are added or removed from the collection. I
wrote it in VB.NET.
If I have a class which creates an instance of the collection and adds
handlers to the events it raises, and then try to serialize the collection I
get an error about the client not being marked as serialized. This is
because of the reference the collection maintains...

I have a class (settings, etc.) which is derived from CollectionBase and
contains a number of fields and a few events. When I create an instance of
this class in my app, and serialize it, it works. If I add an event handler
in my app (for one of the events in my settings class), I get an exception
that my app class is not marked as Serializable. If I mark the app class as
Serializible, I get an exception that Type System.Windows.Forms.Form...

Hi everyone
I have a problem with events.

than it fires the...

I am using C# in Visual Studio 2003.
I would like to serialize a class that contains, amongst other things,
public delegate void DocumentsPreferencesChange(object env, Documents e);
public event DocumentsPreferencesChange OnDocumentsPreferencesChange;
However, as it stands, the classes containing any methods/delegates that have been added to OnDocumentsPreferencesChange also have to be serializable: this I do not want.
I do not actually...

Hi All
If I have a type that contains an event, then serialization tries to
serialize the delegate and its invocation list - not good.
In C#, I can write code like this (follows) - note the use of the
NonSerialized attribute with the field qualifier .
Without the field qualifier I get a compile time error.
In VB.NET, I don't seem to have an equivalent - I can't do

I have a custom collection which derives from Collection<which stores
a number of objects. Before each item is added to the collection - an
event which it exposes is hooked by the collection and the re-fired to
its parent.

Just looking to compile a list of "all the ways to implement events".
I'm NOT looking to get into the merits or mechanics of each in this
thread... just want to identify them all - good, bad, and ugly.
Here's what I have so far
1. Implement via the 'event' keyword (with associated delegate, etc)
2. Expose a private delegate via a public property (really a "roll yer own"
version of the 'event' keyword method).

Hi There.
I'm working on a application with a multiple level object structure.
Object type "Cproject" holds an arraylist of "Csystem".
A "Csystem" contain custom events i listen for in "Cproject"
When i add items to the lists of "Csystem" i also add eventhandlers for the above events.
When the object structure is serialized to an xml-file, and then deserialized, my event handlers are lost, since at the deserialization of "Cproject",...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
