Seems like, to make sure that a pointer doesn't point to an object/function,
NULL (or simply 0) is good enough for both kind of pointers, data pointers
and function pointers as per 6.3.2.3:
3 An integer constant expression with the value 0, or such an expression
cast to type void *, is called a null pointer constant.55)
If a null pointer constant is converted to a pointer type, the resulting

Hi all.
I have a class which performs some tasks for which ever form it get s bound
to using a bindForm methods which accepts a form object.
I'd like to do away with this method as it only ever gets used like this:
BindForm(Me)
Is there anyway, that I can get the form object in the class, when it is
instatianted by the form?

Hi all,
i am pretty new to programming and have a (simple?) problem here:
I want to populate a Treeview with data from a table.
Table layout is:
ID, ParentID, Description
There can be infinite levels, the starting level for ParentID is 0

OK folks here is what I need help with. Lets assume I have a text field
that will contain AlphaNumeric data. There is no set pattern to the
field such that any given character can be either alpha or numeric. I
need a function that will return the requested 'part' of the contents of
the field. A 'part' would be defined as consecutive Alpha or Numeric
characters in the text field.
Examples:
Field Name = cFoo

it would map the
file system hierarchy.

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.

Now, this would greatly impact the work of software developers. The idea...
