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

Hi,
I am developing ASP.NET pages using VS.NET 2003 in windows XP.
I dragged and dropped a dropdownlist on the form. The listitem of the dropdownlist was generated based on database reading. The autopostback was set to TRUE.
The first time the page loaded fine. But when I change the selection in the dropdownlist, I got an IE error. The error basically says that the '_EVENTTARGET' is null or not an object.
The error appears with a little...

Hi!
There is a system where 0x0 is a valid address, but 0xffffffff isn't.
How can null pointers be treated by a compiler (besides the typical
"solution" of still using 0x0 for "null")?
- AFAIK C allows "null pointers" to be represented differently then
"all bits 0". Is this correct?
- AFAIK I can't `#define NULL 0x10000' since `void* p=0;' should work
just like `void* p=NULL'. Is this correct?

Hi,
In some cases when my function returns, I need to return a object of
null state. This is when I return object by value.
(Just like for by pointer, I can return a null pointer ).
It has to be equivalent to null (or uninitialized state) , just
like null iterator (or end iterator) .
has someone worked with the concept of a generic null object , i.e
any object with a null object trait can be treated as null object or
like that, with...

Do you prefer malloc or calloc?

Which of the following two is right to get same storage same as the

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...

Is that a non-conformance?

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...

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....
