Hiya,
I'm setting up some code in the spirit of Design Patterns, OOP, etc. All
nice and well, it handles pretty much all OO style things and serves my
purposes well. There's one last final question remaining: How to properly,
simple and eleganty implement functions. The functions are encapsulated in
the objects, the objects themselves are stored in a binary tree and objects
contain 'methods' (functions) along with data. I don't want to...

I'm using inheritance more than I used to, and I find myself calling a lot
of base class methods. I generally call a base method from a dreived class
like this:
this.MyMethod();
I'm finding it somewhat confusing when I look at the code later, because I
expect to find a method called MyMethod() in the derived class.
I think C# would let me call a base class method from a derived class like

I'm running into an Invalid Cast Exception on an ASP.NET application that runs fine in my
development environment (Win2K server running IIS 5) and a test environment (also Win2K server
running IIS 5), but fails on IIS 6 running on a Win2003 server.
The web uses Pages derived from a custom class I wrote (which itself derives from Page) to provide
some common functionality. The Page_Load handler the failing webpage starts out like this:

I just read a blurb in MSDN under the C++ "ref" keyword which states that:
"Under the CLR object model, only public single inheritance is supported".
Does this mean that no .NET class can ever support multiple inheritance. In
C++ for instance I noticed that the compiler flags an error if you use the
"ref" keyword on a class with multiple base classes. This supports the above
quote. However, under the "CodeClass2.Bases" property (part...

Hi,
I have an existing VC 6 MFC application which communicates asynchronly with
a VC 2005 managed code dll.
I use an unmanaged base class with virtual functions to access methods in
the MFC application.
Furthermore, I use a pointer to an unmanaged function to jump back into the
managed dll.
The managed part is basically a remoting enhancement which asynchronly

Hello all. I have this class with a virtual method and a constructor
that calls this virtual method. A derived class overrides this virtual
method, so I expected that when the base's constructor is called, it
would call the derived version of the method. However, it does not, it
calls the base's version. An example:
class Base

public:
Base() {

You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it.

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:

Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

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...
