Hi All!
I have noticed a strange behavior when using a constant identifier to
initialize an instance list variable in a base class and then trying to
modifying the list in subclasses by using either the list.extend method or
even by having the subclass create a whole new list in the variable.
The following example illustrates the situation.

Hi guys. I've come across a problem when I tried to serialize a class into
xml, only to discover that the parent class's XML Serialization properties
weren't included in the output xml.
Actually, the class I'm serializing is two steps down in the inheritance
ladder. It's got a parent class which also has a parent class :( All those
classes in the hierarchy are Xml Serializable, and I'd think that it should
be obvious that all...

Can anyone please explain to me why the code below throws an exception?
It seems to occur when deserializing an instance of a subclass, whose
base class holds a struct, where said struct holds an instance to a
reference type (but not System.String).
The commented out code are lines that when enabled (and any conflicting
lines disabled) stop the exception from being thrown.
Thanks kindly,
Andrew.

Hi,
This seems to me like a problem that has a simple solution but I can't
for the life of me work it out.
Suppose I have a base class Employee
Public Class Employee
Public FullName As String

Can you create an instance of a subclass using an existing instance of
the base class?
Such things would be impossible in some languages or very difficult in
others. I wonder if this can be done in python, without copying the
base class instance, which in my case is a very expensive object.
Any ideas?
Thanks,

hi, there. i have a problem writing a program which can obtain ip
addresses of machines running in the same local network.
say, there are 4 machines present in the network; , , and
and if i run my program on , it should be able to find "host names"
and "ip addresses" of the other machines; , and ?
i have read some threads posted on this group, however, they only work
for localhost, not the entire network.

I understand how to create a property like this:
class RC(object):
def _set_pwm(self, v):
self._pwm01 = v % 256
def _get_pwm(self):
return self._pwm01
pwm01 = property(_get_pwm, _set_pwm)

Hi,
How Do I create an instance of a derived class from an instance of a
base class, essentially wrapping up an existing base class with some
additional functionality. The reason I need this is because I am not
always able to control/create all the different constructors the base
class has. My problem can be described in code as follows ...
/* This is the base class with a whole heap of
constructors/functionality*/
public class Animal

I'm trying to display my array of objects in a GUI. How do I get JLabel to refer to the data in my objects? I've read my textbook and some tutorials online I just cannot get this. Plus all the examples I've seen are creating the information that will be displayed from scratch, while I have to use my previously created classes and add a GUI to it. I'm trying to do this GUI using JLabels but it won't let me refer to my CD class methods that...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
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...
