Hello,
We have a C#.NET app which is calling a Java webservice. We use the wsdl
file exportted from the java webservice to create our web-reference in Visual
Studio. We are able to create the parameter classes and call the webservice
just fine.
Our problem is, within our .Net app, we have some value objects ( like
floats, for instance ) which are meant to be null. Since there is no null
float, we use float.minvalue to indicate a...

How are people handling NULL values for value types.
Descriptions of problem
Say you have a typical method with the signature:

Now say you only want the firstName and lastName parameters to be

Hi,
I've created a UserControl-derived class called MyUserControl that is
able to persist and subsequently reload its state. It exposes two methods as
follows:
public void Serialize(Stream s);
public void Deserialize(Stream s);
Within the MyUserControl class, there is a field of type MyInnerClass

Back in C++, I had a type that looked something like this (entering
from memory so this might not quite compile):
template <class T>
class NotNull
{
private:
T* value;
public:
NotNull(T* ptr)

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...

I wonder if there's a simple way to specify the default
values so that when i call a function designed to receive
an int and a double, i can specify the first but not the
latter. Something like:
int foo (int i, double d) {...}
but invoked by
int a = foo (5);

As explained in "Using pointers vs. references"
http://groups.google.ee/group/borland.public.delphi.objectpascal/browse_thread/thread/683c30f161fc1e9c/ab294c7b02e8faca#ab294c7b02e8faca ,
the pointers are allowed to be null, while references must refer an existing
variable of required type. The null is normally used for making optional
parameters. But there is no way to pass null reference in C#. Something is
missing.

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...

Overview:
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,...
