Error in msvc in building inheritance.obj to build hello.pyd
Hello,
I am trying to build the boost 1.31.0 sample extension hello.cpp.
I can not compile the file inheritance.cpp because the two
files containing some templates: adjacency_list.hpp and mem_fn.hpp can
not compile.
Does anyone have any solutions?

I have an application that is composed of a set
of "Content" dlls and a viewer application. The viewer
calls a standard set of functions that are present in all
the dlls. I maintain this by making my contnent dlls
implement an interface created in vb6. The viewer
application is bound to this interface. This way, I am
able to add Content without redeploying the dlls (I just
have to add the new dlls). I want to write new content

Hello!
What does this mean.
"The use of inheritance to provide various implementations of a single
abstraction tightly binds these implementations to the abstarction. Therfore
it, is difficult to update the client's code and reuse the abstraction, In
C++, the complete class definition, including the private and protected
sections, is needed to compile the client's code; this leads to a tight
coupling between the abstraction and its...

Hello experts!
I have a small program that is using multiple inheritance.
There are 4 classes involved
I get 4 compile error that I can't figure out why.
It's this row which is located in the main program see below that is causing
these compile errors.
cout << p->getName() << endl;
Here is the first compile error the other might be a consequesce of the
first one.

Recently, I tried and did a poor job explaining an idea I've had for handling
a particular case of implementation inheritance that would be easy and obvious
in a fully OOP language, but is not at all obvious in VBA which lacks
inheritance. I'm trying the explanation again now.
I often find cases where a limited form of inheritance would eliminate
duplication my code that seems impossible to eliminate otherwise. I'm getting

I'm writing a family of classes which all inherit most of their methods and
code (including constructors) from a single base class. When attempting to
instance one of the derived classes using parameters, I get CS1501 (no method
with X arguments). Here's a simplified example which mimics the
circumstances:
namespace InheritError {
// Random base class.
public class A {
protected int i;

Hello,
I have code that I wish to use in many web applications. Basically
sort of stand utility stuff. So from Visual Studio Project I select
add a component and chose Component Class. Lets say I enter code at
the end of this question in to the code section.
How then would I reference this in a new Web Application (or in the
same web application for that matter?)

Here is the problem. I built LibA and LibB as class library projects in the
same solution as my web application HelloWorldWebApp. Wherever necessary I
added project references. Everything compiled nicely and ran smoothly.
After I finished my development, I wanted to use LibA across multiple
projects so I removed LibA from the solution and copied the LibA.dll to a
common location and added it to HelloWorldWebApp as a file reference. Now,...

I remember reading on parashift recently, that "Composition is for code
reuse, inheritance is for flexibility" see
(http://www.parashift.com/c++-faq-lite/smalltalk.html#faq-30.4)
This confused me somewhat as I have always thought you get code reuse
"for free" with inheritance. Am I missing something?. Will someone care
to explain ??

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...
