I've done some C++ and Java in the past, and have recently learned
a fair amount of Python. One thing I still really don't get though
is the difference between class methods and instance methods. I
guess I'll try to narrow it down to a few specific questions, but
any further input offered on the subject is greatly appreciated:
1. Are all of my class's methods supposed to take 'self' as their
first arg?
2. Am I then supposed to call...

Hi,
I am working on an application that can use functionlity in some sort of
plugins. I have implemented this by using Assembly.LoadFrom and
MethodInfo.GetMethods.
The calling of the plugins is handled in threads.
All works fine, but when I call a method that processes for some time, the
mainthread (my form) becomes unresponsive.

Hi,
I'm trying to figure out how to dynamically load an assembly and get
an IClientPlugin interface to a class. I can get an "Object"
reference to it after doing an "Activator.CreateInstance" call, but is
there any way to get an IClientPlugin reference to it?
Trying to do a "CType(obj, IClientPlugin)" throws an exception.
Here's the code that loads the assembly and calls a method called

I used WSDL.exe to generate a client side web proxy for a web service, called
the web service, got the results but an array returned by the web service is
not in the results.
However if I use "Add Web Reference" for the same service the same function
works appropriately.
Here is the client proxy generated from WSDL.exe

This post was originally in the C# Corner site, but their server is
down. I'd like to see if this group can answer.
I program in C++ and am learning C#.
The issue is: why should anybody bother in C# with pass-by-reference
using the "ref" keyword or "out" for objects in a method parameter
list, when, after all, it appears in C# that for all intents and
purposes a reference is always being passed, rather than the real
object (with, it...

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:
