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 try at generics. This creates a collection that implements
IInvoke and IDisposable and Adds types that implement IInvoke and
IDisposable. When the collection goes out of using scope dispose is
called on all members of the collection. Calling Invoke on the
collection calls Invoke on each member of the collection.

I'm in the process of expanding my knowledge and use of Class Modules.
I've perused MSDN and this and other sites, and I'm pretty comfortable
with my understanding of Class Modules with the exception of custom
Collection Classes.
Background: I'm developing an A2K .mdb to be deployed as an .mde at my
current job-site. It has several custom controls which utilize custom
classes to wrap built-in controls, and add additional functionality....

I am developing a new management system for my company, and with it have 3

put in a userCollection class for all my users. There are many other classes
like this on as well. However, what is the best way to do my collections? I

Dear All,
I am trying to decide on to create a collection object for a project that I
am working on. I am fairly new to OOP so this may be on the basic side. I
have looked on the groups, but can't seem to find the answer I am looking for
- just more questions!
I want an object to hold Case details, one of the properties of this Case
class will be RequestedBy. I ideally want this property to be a collection
of User Objects (which...

I hope someone can shed some light on an error I've been experiencing for
sometime now, but can no longer continue to ignore :-(
I've created a custom entity class which implements IEditableObject. I have
then created a custom collection for this custom entity which naturally
inherits CollectionBase and implements IBindingList.
When I bind my custom collection to a DataGridView and started editing, it
works correctly only up to the...

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

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

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,...
