Consider the code below,

Hi all
I have been searching everywhere for this, but have not found a
solution, yet.
What I need is to create an object that is an instance of a class (NOT a
class instance!) of which I only know the name as a string. This what I
tried:

I want to ensure that there is only ever one instance of my app running on a
single PC at any time. I understand that I can achieve this by using a mutex
and, if I can't take ownership of the mutex, I know there is another
instance of my program running.
Problem is, how do I get the "new" instance to communicate with the "old"
instance? The new one will have been started with a command line parameter
that I want to pass to the old...

Here's wishing you MERRY CHRISTMAS and Festive seasons's greeting!!
Now this has been bugging me for quite a while and I seek your help in
setting my mind to peace.
As part of DB2 Instance creation on Unix, I issue this command (from
standard script):

I just ran across a case which seems like an odd exception to either
what I understand as the "normal" variable lookup scheme in an
instance/object heirarchy, or to the rules regarding variable usage
before creation. Check this out:
>>> class foo(object):
.... I = 1
.... def __init__(self):
.... print self.__dict__
.... self.I += 1

hi,
i want to know how does c++ compiler prohibits the creation of instance
of an abstract class?
i think it must be checking on the vtable entry if there is an entry
with zero(indicting abstract class) but exactly how it is done.
thanks in advance

Hi
I found that a type/class are both a subclass and a instance of base
type "object".
It conflicts to my understanding that:
1.) a type/class object is created from class statement
2.) a instance is created by "calling" a class object.

Hi I wonder if you can set what subclass a class should
have at instance creation.
The problem is that I have something like:
class CoreLang():
def AssignVar(self, var, value):
pass
class Lang1(CoreLang):

My project involves reading magstripe cards, capturing an ID number, then spinning off to do some other things including taking a photograph. 99% of this is done and good. All early phases of work went well... Until the final assembly and "beefing up" of the project.
The magcard reader is made by Magtek. They provide an ActiveX component as the sole means of communication with this RS-232 serial port device. It works great as long as it...

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