I'm using the following syntax to loop through a list collection:
For Each PropertyActor As JCPropertyActor In MyProperty.PropertyActors
i = IndexOf(PropertyActor)
Next
How do I get the index of the current object within the loop? I'm using IndexOf(PropertyActor) but this seems inefficient as it searches the collection when I alr...
I'm trying to create a Quicksort base class using VB.NET, taking it an array of IComparable elements. The signature looks like this:
public shared sub Sort(ByVal values() as IComparable)
However, when I pass in an array of doubles, the compiler is giving me errors.
Dim numbers(100) as double
Dim random as new Random(0)
for i as in...
Are there any classes in the .NET framework I can use to throw an event if time has caught up with a specified DateTime object?
If there isn't, what are the best practices when checking this? Create a new thread constantly checking? A timer (heaven forbid ;) )?

I am trying to use a class from a C# assembly in vb.net. The class has ambiguous members because vb.net is case insensitive. The class is something like this:
public class Foo {
public enum FORMAT {ONE, TWO, THREE};
public FORMAT Format {
get {...}
set {...}
}
}
I try to access the enum: Foo.FORMAT.ONE

I'm not too familiar with generics (concept or the syntax) in general (short of using them in collections and what not), but I was wondering if the following is the best way of accomplishing what I want. Actually, I'm not entirely positive generics will solve my problem in this case.
I've modelled and mapped a few dozen objects in NHibe...

We have a service that runs methods used for data import/export at specified intervals. To test these methods we have a little application with a single button that, when clicked, instantiates the import/export class and invokes the desired method. Nothing fancy. I would like create a more robust test application that can receive debu...

When .NET was first introduced, it was common (and an obvious choice) for people coming from a VB6 background to jump into the .NET world with VB.NET rather than C#. Today, we use C# for over 90% of our projects, but occasionally we will provide support or services to organizations that have standardized on VB.NET.
Today, there several ...

If I have a VB.Net function that returns an Int32, but uses an unsigned int (UInt32) for calculations, etc. How can I convert a variable "MyUintVar32" with a value of say "3392918397 into a standard Int32 in VB.Net?
In c# if I just do a "return (int)(MyUintVar32);", I get -902048899, not an error.
I've tried several different method...
The scenario: 2 user controls (foo.ascx and fum.ascx)
foo has a method that would really like to access a property from fum. They live on the same page, but I can't find a very simple way to accomplish this sort of communication.
Any ideas?

I need generate thumbnails for a bunch of jpegs (200,000+) but I want to make sure all of my thumbs have a equal height and width. However, I don't want to change the proportions of the image so I need to add empty space to the shorter dimension to "square it up". The empty space's background color is variable.
Here's the code snippe...
