There is no shorthand for Visual Studio 2008 or prior for VB.NET. 

In Visual Studio 2010 and beyond, you can use the following shorthand:

    Public Property FirstName as String

This will be handled as your short version in C# is - I think they call it &quot;Auto Property&quot;

See also: [Auto-Implemented Properties (Visual Basic)][1]

In Visual Studio 2008, after typing just the keyword `Property`, press the &lt;kbd&gt;Tab&lt;/kbd&gt; key. It&#39;ll paste a template snippet for you which you can fill very quickly.

But yeah, there is not a replacement of a Visual Basic 10-type shortcut in Visual Basic 9.


Unfortunately, Visual Basic 9 (which ships with .NET 3.5/Visual Studio 2008) does not have automatic properties.

My understanding is that a hash code and checksum are similar things - a numeric value, computed for a block of data, that is *relatively* unique.

i.e. The probability of two blocks of data yielding the same numeric hash/checksum value is low enough that it can be ignored for the purposes of the application.

So do we have two words for the same thing, or are there important differences between hash codes and checksums?

In my class design, I use abstract classes and virtual functions extensively. I had a  feeling that virtual functions affects the performance. Is this true? But I think this performance difference is not noticeable and looks like I am doing premature optimization. Right?

Is there a VB.NET equivalent to the C#:

    public string FirstName { get; set; }

I know you can do 

    Public Property name() As String
       Get
          Return _name.ToString
       End Get
       Set(ByVal value As String)
           _name = value
       End Set
    End Property

But I can&#39;t seem to google up an answer on a Visual Basic shorthand.

Is it possible to deploy a Windows Service using ClickOnce? If so, how do you achieve this?

Currently we have to use a Deployment project, and the installation process could be simplified greatly by using ClickOnce.

I am currently writing a small framework that will be used internally by other developers within the company.

I want to provide good Intellisense information, but I am not sure *how* to document thrown exceptions.

In the following example:

    public void MyMethod1()
    {
        MyMethod2();

        // also may throw InvalidOperationException
    }

    public void MyMethod2()
    {
        System.IO.File.Open(somepath...); // this may throw FileNotFoundException

        // also may throw DivideByZeroException
    }

I know the markup for documenting exceptions is:

    /// &lt;exception cref=&quot;SomeException&quot;&gt;when things go wrong.&lt;/exception&gt;

What I don&#39;t understand is how to document exceptions thrown by code **called by** `MyMethod1()`?


* Should I document exceptions thrown by `MyMethod2()`
* Should I document exceptions thrown by `File.Open()` ?


What would be the best way to document possible exceptions?

I&#39;m looking for a function that will convert a standard IPv4 address into an Integer.  Bonus points available for a function that will do the opposite.

Solution should be in C#.

How to convert an IPv4 address into a integer in C#?

I&#39;m making a call:

    myResult = MakeMyCall(inputParams, out messages);

but I don&#39;t actually care about the messages.  If it was an input parameter I didn&#39;t care about I&#39;d just pass in a null.  If it was the return I didn&#39;t care about I&#39;d just leave it off.  

Is there a way to do something similar with an out, or do I need to declare a variable that I will then ignore?

In .Net (C# or VB: don&#39;t care), given a file path string, FileInfo struct, or FileSystemInfo struct for a real existing file, how can I determine the icon(s) used by the shell (explorer) for that file?

Is there a way to convert a `List(of Object)` to a `List(of String)` in c# or vb.net without iterating through all the items? (Behind the scenes iteration is fine – I just want concise code)

**Update:**
The best way is probably just to do a new select

    myList.Select(function(i) i.ToString()).ToList();

or

    myList.Select(i =&gt; i.ToString()).ToList();

I know VB.Net and am trying to brush up on my C#. Is there a `With` block equivalent in C#?


With block equivalent in C#?

For the following block of code:

    For I = 0 To listOfStrings.Count - 1
        If myString.Contains(lstOfStrings.Item(I)) Then
            Return True
        End If
    Next
    Return False

The output is:

**Case 1:**

&lt;!-- language: lang-none --&gt;

    myString: C:\Files\myfile.doc
    listOfString: C:\Files\, C:\Files2\
    Result: True

**Case 2:**

&lt;!-- language: lang-none --&gt;

    myString: C:\Files3\myfile.doc
    listOfString: C:\Files\, C:\Files2\
    Result: False

The list (listOfStrings) may contain several items (minimum 20) and it has to be checked against a thousands of strings (like myString).

Is there a better (more efficient) way to write this code?


Check if a string contains an element from a list (of strings)

In JavaScript, there are two values which basically say &#39;I don&#39;t exist&#39; - `undefined` and `null`.

A property to which a programmer has not assigned anything will be `undefined`, but in order for a property to become `null`, `null` must be explicitly assigned to it.

I once thought that there was a need for `null` because `undefined` is a primitive value and `null` an object. It&#39;s not, even if `typeof null` will yield `&#39;object&#39;`: Actually, both are primitive values - which means neither `undefined` nor `null` can be returned from a constructor function, as both will be converted to an empty object (one has to throw an error to proclaim failure in constructors).

They also both evaluate to `false` in boolean contexts. The only real difference I can think of is that one evaluates to `NaN`, the other to `0` in numeric contexts.

So why is there both `undefined` and `null` if this just confuses programmers who are incorrectly checking for `null` when trying to find out whether a property has been set or not?

What I&#39;d like to know is if anyone has a reasonable example where it&#39;s necessary to use `null` which couldn&#39;t be expressed using `undefined` instead.

So the general consensus seems to be that `undefined` means &#39;there is no such property&#39; while `null` means &#39;the property does exist, but holds no value&#39;.

I could live with that if JavaScript implementations would actually enforce this behavior - but `undefined` is a perfectly valid primitive value, so it can easily be assigned to existing properties to break this contract. Therefore, if you want to make sure if a property exists, you have to use the `in` operator or `hasOwnProperty()` anyway. So once again: what&#39;s the practical use for separate values for `undefined` and `null`?

I actually use `undefined` when I want to unset the values of properties no longer in use but which I don&#39;t want to `delete`. Should I use `null` instead?

Why is there a `null` value in JavaScript?

So lets say I have this interface:

    public interface IBox
    {
       public void setSize(int size);
       public int getSize();
       public int getArea();
      //...and so on
    }

And I have a class that implements it:

    public class Rectangle implements IBox
    {
       private int size;
       //Methods here
    }

If I wanted to use the interface IBox, i can&#39;t actually create an instance of it, in the way:

    public static void main(String args[])
    {
        Ibox myBox=new Ibox();
    }


right? So I&#39;d actually have to do this:

    public static void main(String args[])
    {
        Rectangle myBox=new Rectangle();
    }

If that&#39;s true, then the only purpose of interfaces is to make sure that the class which implements an interface has got the correct methods in it as described by an interface? Or is there any other use of interfaces?


Is there more to an interface than having the correct methods

I have written a little bit of C, and I can read it well enough to get a general idea of what it is doing, but every time I have encountered a macro it has thrown me completely. I end up having to remember what the macro is and substitute it in my head as I read. The ones that I have encountered that were intuitive and easy to understand were always like little mini functions, so I always wondered why they weren&#39;t just functions.

I can understand the need to define different build types for debug or cross platform builds in the preprocessor but the ability to define arbitrary substitutions seems to be useful only to make an already difficult language even more difficult to understand.

Why was such a complex preprocessor introduced for C? And does anyone have an example of using it that will make me understand why it still seems to be used for purposes other than simple if #debug style conditional compilations?

Edit:

Having read a number of answers I still just don&#39;t get it. The most common answer is to inline code. If the inline keyword doesn&#39;t do it then either it has a good reason to not do it, or the implementation needs fixing. I don&#39;t understand why a whole different mechanism is needed that means &quot;really inline this code&quot; (aside form the code being written before inline was around). I also don&#39;t understand the idea that was mentioned that &quot;if its too silly to be put in a function&quot;. Surely any piece of code that takes an input and produces an output is best put in a function. I think I may not be getting it because I am not used to the micro optimisations of writing C, but the preprocessor just feels like a complex solution to a few simple problems.

What are C macros useful for?

Python&#39;s inner/nested classes confuse me. Is there something that can&#39;t be accomplished without them? If so, what is that thing?

This came up at the office today.  I have no plans of doing such a thing, but theoretically could you write a compiler in SQL?  At first glance it appears to me to be turing complete, though extremely cumbersome for many classes of problems.  

If it is not turing complete, what would it require to become so?

Note: I have no desire to do anything like write a compiler in SQL, I know it would be a silly thing to do, so if we can avoid that discussion I would appreciate it.
