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:

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.

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....

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...
