Week #18 vb.net



Introduction
Let me begin by differentiating vb.NET from vb.
It is true to say that the vb in both does stand for Visual Basic and that they share a similar looking syntax, but they are very different. The most important difference is in how they are implemented.

vb (that's without the .NET) is compiled into a native executable
vb.NET (that's with the .NET) is compiled into a CIL which is then interpreted by the .NET Framework.

Where to download vb.net?
There are several editions of the vb.net out in the wilds;-
Visual Basic 2005 (aka VB8), Visual Basic 2008 (aka VB9)
But I suggest you uses the latest version
Visual Basic 2010 Express Edition (aka VB10)
Which has the latest version of the .NET Framework, .NET 4.0.

Useful Links

A couple ideas to get you started.
Note: Yes we are aware that some one following Code Samples do break the Syntax Highlighter of the code tags.

• Disable the Legacy Support for vb6
  Its a great way to learn the new stuff.
  Yeah a I know it takes a little getting used to, something you could do before you can't do Now.
  Eg Control Arrays.
  
  
• Discover some of the benefit of Using Object Orient Design by Create your own class object.
  
  
• Create DLL of useful bits. (Extension Methods)
  The following one is on I use lot.
  
  Spoiler

  
  Title: IsntNull
  
  

  Imports System.Runtime.CompilerServices
  Public Module Exts
  
   <Extension()>
   Public Function IsntNull(ByVal Source As Object) As Boolean
    Return (Source IsNot Nothing)
   End Function
  
  End Class
  
  

  
  
  Its much easier to write & read.
  

  If  SomeObj.IsntNull Then
   ' Code '
  Else
   Throw SomeException
  EndIf
  

  
  
  
  
  
• Investigate Generics
  For you don't know it a way of sharing and simplifying your code. The (Of T) Stuff
  
  
  Spoiler

  
  A good example of this is the Generic Collections.
  
  

  Dim StringList as New List(Of String)
  Dim Numbers as New List(Of Integer)
  Dim Dic1 as New Dictionaty(Of Integer, String)
  Dim Dic2 as New Dictionary(Of MyMadeUpClass, OtherClass) 
  
  

  
  
  
  
  
• Play with LINQ
  It more powerful than you think.
  Try combining LINQ wirh some Extension Methods

  I have of a bit of it to write the 99 Bottles of Beer Song.
  I could have had instead number using words instance, but would be showing off.
  99 Bottles of Beer
  
  

  Module Module1
  
    Sub Main()
      Dim Bottle = (From Bottles In Enumerable.Range(0, 100).Reverse).ToList
      Dim GreenBottlesSong =
        Bottle.Select(
          Function(Bottles As Integer)
            Return Bottles.OfBeer & " on the wall, " & Bottles.OfBeer & Environment.NewLine &
              If(Bottles > 0,
                 "Take one down and pass it around, " & (Bottles - 1).OfBeer & " on the wall.",
                 "Go to the store and buy some more. " & 99.OfBeer & " on the wall.") &
               Environment.NewLine
          End Function).AllTogether
      Console.Write(GreenBottlesSong)
  
  
      ' Wait for a key press before exitting
      Console.WriteLine("Press Any Key to exit")
      Console.ReadKey()
  End Sub
  
    <System.Runtime.CompilerServices.Extension()>
    Public Function OfBeer(ByVal _Bottles As Integer) As String
      Return If(_Bottles > 0, String.Format("{0} Bottle{1}", _Bottles, If(_Bottles > 1, "s", "")), "No More Bottles") & " of beer"
    End Function
    <System.Runtime.CompilerServices.Extension()>
    Public Function AllTogether(ByVal Strings As IEnumerable(Of String), Optional ByVal j As String = vbCrLf) As String
      Return String.Join(j, Strings)
    End Function
  
  End Module
  
  

  
  
  
  
  So far I been only showing Console Programs, which is great for testing out ideas with hassle dealing with challenges that an Asynchronous MultiThreaded Graphical Interface. It lets you focus on the core language. Learn the language features, controls and Forms are way easier user. It easy to change the project type to a Windows Forms application later on.
  
  Any How.
  
  
• XML Literals
  
  One feature if VB.net and not yet available ro C# Programmers, (Who are calling out for them.)
  Even as especially in VB10 since they (Microsoft) have included the XML-to-Scheme Template (Express Edition Too)
  Previously it was an extra download. What it does is allows add Intellisense support over an XML document, it has the schema of.
  
  
  Spoiler

  
  

      Dim xml_Literal =
      <Stuff>
        <Example Number="1">
          <Title>Example 1</Title>
          <Content>
             This is example
           </Content>
        </Example>
        <Example Number="2">
          <Title>Example 2</Title>
          <Content>
             This is an another example
           </Content>
        </Example>
      </Stuff>
      Console.WriteLine(xml_Literal)
  

There is an Periodic Table Example somewhere on my blog The Madman Scribblings that uses a lot of the above (of not all.)

Ain't RSS feeds xml based? What about the Google APIs?

Now you are starting to seeing the power of them.

You, sir, need some capitalization.

Hmm, and that had to be posted why exactly? Please keep posts in this thread related to the Challenge for the week listed

[SwiftStriker00]

Wow I didnt even know we had a spoiler tag until your post. I want to try this challenge since its so close to C# / .NET, and i've worked with the vb syntax before. Im busy this week so it might get back logged but, thanks for the detailed post, more info always helps.

I daring, double daring you to try vb.net and not to have fun exploring it.

What do I get if I win?

In all seriousness, I have to agree with him. I mean, he even formatted the title of this thread wrong. Let's be consistent.

And before you're forced to reiterate the ol' "shut up" routine, I'll save you the trouble and not post here unless I have input related to the challenge.

Peace and harmony. <3

Seeing that nobody seems to be trying this one.
For any who's interest here mine first entry.

For a bit of fun messing around a console app, come with a DSL that allow the draw pictures (sort of).

I wonder why. Remember this thread?

[Dogstopper]

I've been messing around with VB.NET the past week or so (no clue about this challenge), but I think I'll make the second contribution: a notepad clone (No printing functionality yet). I'd say the most interesting part is the persistent settings (like Font and word wrap settings stay even after application closes and reopens). I used My.Settings!

Comments?

Some of the code was written with help from the tuts here and other spots took a couple of weeks of banging my head against the wall. Right now I've been trying to figure out the savefiledialog and how to save a picture image because I'm also working on a picture viewer. But I just can't find a really good tut on the savefiledialog.

VB IS FUN!
