This will be your first Visual Basic Application. I will try to explain everything in as much detail as I can. This Simple program features a button. When you click on the button, a MessageBox pop's up and displays, "Hello World." Any Questions about this tutorial, please visit vbProgramming Forums.

Starting Up
When you open up Visual Studio. NET, there will be a "Start Page." This displays either your most recent programs, or your "profile." In the start page, select, 'My Profile' (to your left). Make the first list box, "Visual Basic Developer." Now, VS. NET is now arranges itself to make it more resourceful for VB.NET developers.  The next thing you have to do is create a new project, go to File | New | Project. Select Windows Application and name the project "Hello World".
You will see a blank window, this is known as the form. You can drag and drop components from the toolbox (look to the left of the form). Once you do that, you will set their properties such as Name, Height, Width, Position, and Text.

Creating Objects
First, create a new button on the form, drag and drop the button control from the toolbox (or double-click it) and place it on the form. The button's default text should be "Button 1".

Modifying Properties
Click the button on the form, go to the properties window (bottom-left) change the Text property to "Click Me". The button will now say, "Click Me" instead of "Button1."Set the name property to MyButton. The name property is important, because when you code, you must specify what object you are referring to (like MyButton and MyTextBox). Its just like creating Robots. They all look alike, you just need to name them in order for them to know that you are talking to them. (OK, maybe this is a far-fetched but.. anyway, a name is a name.)

Coding and Creating Events
Coding is obviously an important aspect of programming! Our program doesn't do anything yet, we need to code in order to tell the button what to do. If we don't code, our button will not do anything. So, open up your code (View |Code or press F7). You will notice (up at the top), 2 drop down menus. The first one is the object Menu and the one next to it is the events menu. In the objects menu, select: MyButton. In the events Menu select Click. For future references, I will say "MyButton.Click" from now on. When you selected MyButton and Click, VB.NET generated some code for you. This is to save a LOT of time writing code! All you need to worry about are the first 2 words (Sub MyButton_Click) and the last 2 words (End Sub). Well, that should be self explanatory, lets take a look at what it generated for us. The area in green is what I have typed in, read it thoroughly.

---------------------------------------------------------------------------------------------------------------------------------------------------

'In Between these 2 lines are the code that will be executed when MyButton is clicked. 
'This line is a comment, its not real code, its just there so that people can understand the code
'A comment is preceded by an apostrophe ( ' ). It is a really helpful way of making sure you don't get confused by your code

End Sub
---------------------------------------------------------------------------------------------------------------------------------------------------

In between both lines, type in:

MessageBox.Show("Hello World!")

Running your Program
Everything in between MyButton.Click and End Sub Executes when you click MyButton. In this case, when you click MyButton, a 'MessageBox' appears, saying Hello World. Run your program. Try it out! Press F5 to run your program. An alternative way to run your program is to go to Debug | Start. This is your first Visual Basic program (I think)!
