In VB 6, the loop iterator v in the following code must be a variant.
dim v as variant
dim c as new collection
for each v in collection

next v
What is the general translation in VB 7.1 and VB 8 Beta 1? Also, is there
an easy way to force "v" to be an early bound variable. In VB 6 this can be

Hi,
I need to make a strongly typed collection of x, and the simplets way is to
inherits list(of x). With that I can bind to a list-control. However - i
don't need all the methods from list(of x).
If I make a private list as list(of x) in a class and implements IList(of x)
I can control what methods to be public. I works - but now I can't bind the
collection to a listbox og grid (it says something about complex datatype).

Here is my first attempt at a deterministic collection using Generics,
apologies for C#. I will try to convert to C++/cli.

I need to create arrays of a custom data type (which is composed of
various strings, ints, the usual). The original was built using
CollectionBase. I was thinking about redesigning to use generics, but
I realized that DataSets may also work here.
I do need to display and edit lists of the items at various places.
In the previous version I used a custom ListView for most display
purposes.
Given that DataSets in VS2005 have so many...

Hi,
the msdn documentation provides an Dinosaurs example that uses the
objectmodel.collection class. Just have a look on the help page for this
class.
I don't understand what happens here. Or I cannot find more detailed
documentation for this behavior. What I mean is the invocation of the
Dinosaurs.Add method which is derived from Collection(of String). The method
seems to invoke the overridden InsertItem method. Can this method be...

Hello,
I'm hoping to do something using Generics, but I'm not sure it's possible.
Let's say I want to have a bunch of business objects and a data access class
cooresponding to each business object. For each business object, I would
have something like below:
public class Apple
{
//apple stuff

I have a design question. I am creating a custom collection of products.
The unique key for the products is productId which is an integer.
By default, IndexOf(object obj), when obj is an int, would return the value
of obj because it returns the index of the item at position obj.
Thoughts I had were to let the default method perform the default behavior
and then create an overload as IndexOf(int index, ProductSearchCriteria
criteria)...

I'm pretty new to OOP and I'm just starting looking at generics and
collection classes. I understand why I might want to create a business
class, but can somebody please explain to me the reasons behind creating
collection classes?
Many thanks,

Can someone explain a few things about collections to me.
In C# 2 generics, you can create a collection class by inheriting from
System.Collections.ObjectModel.Collection. Using this you can iterate through
the collection and use "foreach" on the collection.
public class Cars : System.Collections.ObjectModel.Collection<Car{ }
So, could someone explain to me why you would want to create a GENERIC
custom collection class.

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...

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...
