Visual Basic .NET - English

Visual Basic .NET Forms

In the Visual Basic NET design time environment, the first thing to concentrate
on is that strange, big square in the top left. That’s called a form.
It’s actually the pretty bit of your programme, the part that others
will see when they launch your masterpiece. Granted, it doesn’t look
too attractive at the moment, but you’ll soon discover ways to lick
it into shape.

Running your VB Forms

To run the form, try this:

  • From the menu bar, click Debug
  • From the drop down menu, click Start
  • Alternatively, press the F5 key on your keyboard
  • Your programme is launched

Congratulations! You have now created your very first programme. It should
look like this:

A VB NET Form Running as a Programme

Click the Red X on the form to stop it from running. You will
then be returned to the software environment.

If you look at the bottom of the screen, you’ll see an Output Window:

The Output window in Visual Studio Express 2012

You can get rid of this by clicking the pin or the cross on the right-hand

Close the Output window

If you compare the form when you create a new project with the one above
when its running, you’ll see that they look very similar. But the one above
is actually a real programme, something you could package and sell to unsuspecting
village idiots.

So what’s going on? Why the two different views? Well, Visual Basic has two
distinct environments, a Design environment and a Debug environment.
Design Time is where you get to play about with the form, spruce it up, add
textboxes, and buttons, and labels (and code, of course ); Debug is where
you can test your programme and see how well it performs. Or doesn’t perform,
as is usually the case.

But don’t worry about the terminology, for the time being. Just be aware
that there’s a two step process to VB programming: designing and debugging.

So, let’s get on and do some designing! Before we can start designing a form,
though, we need some tools. And where are tools kept? In a toolbox!
