Hi
Could someone clarify for me the method parameter passing
concept?
As I understand it, if you pass a variable without
the "ref" syntax then it gets passed as a copy.
If you pass a variable with the "ref" syntax then it gets
passed as a reference to the object and any changes to

I have a bit of a problem with an overloaded operator that I'm writing that
I have distilled down to an example in the code below. Essentially, I have
an operator function (+=) that takes a reference parameter of class Poly.
If I use it with a named object (of type Poly), as in:
P1+=P4;
where P1 and P4 are both local variables of the class type, it works fine.
If I try to use an anonymous object on the right side, then I get an error...

Hi
Just read this article http://www.artima.com/intv/choices.html.
Towards the end of the dicussions, when asked "Did you consider
including support for the concept of immutable directly in C# and the
CLR?" Anders' reply included this comment: "The concept of an
immutable object is very useful, but it's just up to the author to say
that it's immutable."

Hi
What I have learned is that a variable is just a reference when dealing with Objects.
Are you supposed to use ByVal or ByRef in functions? They produce the same result or have I missed something?

One way of passing data to a thread is to encapsulate the thread inside a
class. However, I can't refer to my main form objects from within the
class/thread as it says "Reference to a non-shared member requires an Object
reference".
How do I refer to items such as Textbox1.text etc on my main form?

Hello fellow C# programmers,
This question is more about general practice and convention so here
goes:
I got into a discussion with a co-worker who insisted that as a general
practice all objects should be passed by reference using the ref
keyword generally speaking because as the writer of code you are
conveying your intentions that an Object should/can be modified by your
function.

Hello,
I'm writing a service using VS2005 and C#. I've found that only the objects
used as parameters in WebMethods get exported to proxy dlls and the Service
Description. I'd like my service clients to be able to use the objects I've
defined in messages to the service and send them as "object" parameters or as
embeded items in other objects.
I can work around the problem by declaring all of the objects as public
members of a dummy...

This may sound very elementary, but can you trap when your object is
set to null within the object?
I have created a class that registers an event from an object passed
in the constructor. When my object is destroyed, I want my object to
un-register this event. If I don't then the object would never be
destroyed until the object I passed in the constructor is destroyed.
I have implemented a Dispose(), Dispose(bool), and ~Finalize...

A quick sanity check, and I think I am correct, but just to make
sure: if you have a bunch of objects that are very much like one
another you can uniquely track them simply by using an ArrayList or
Array, correct? An example: create the object, create an array, the
stuff the object into the array. Later on, assume the object is
mutable, the object changes, but you can find it, if you have enough
state information to uniquely identify...

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,...
