Overview of VB.NET
• .NET is a new platform for building
distributed applications
– Focus on Web Integration
– CLR – Common Language Runtime
Starting VB.NET
• First Time
– “My Profile” will be displayed
• Successive Times
“Get Started” tab will be selected
• Open Project
– From “My Projects” Directory
• New Projects

What’s New – VB6 to .Net Help
Online Community – Newsgroups
Headlines – Latest MSDN News and Info
Search Online – Search MSDN
Downloads – Add-ons, Service Packs and
product Upgrades
• XML Web Services – Available external
sources
Other IDE Sections
• Solution Explorer (Ctrl+R)
• Toolbox (controls or text) available for
project.
• Server Explorer – work with server
resources.
• Properties Window – View or modify the
properties of a selected object
Other IDE Sections
• Dynamic Help – Help topics related to
current object.
• Output – Displays information about
current IDE operation when compiling.
• Debug – Used to view the value of watch
variable.
List of Objectives:
Let’s Get Started:
• Create an application using VB.NET
• Start getting familiar with all of the various
functions in the IDE.
• Use the Code Editor and Object Browser.
.NET Categorization
• Application – a software program that runs
(executes) on a computer.
• Project – a set of files (e.g. VB.NET source
code, graphic files, Icon files) that are used
to build an Application.
• Namespace - Namespaces organize the
objects defined in an assembly

Assemblies
For a .Net application assemblies form the fundamental
unit of
– Deployment
– Version control
– Reuse
– Activation scoping
– Security permission
Assemblies take the form of
– an executable (.exe) file
or
– a dynamic link library (.dll) file
Assemblies provide the common language runtime with
the information it needs to be aware of type
implementations.
Assemblies are different from .exe or .dll files because
they contain all the information you would find in a type
library, plus information about everything else necessary
to use the application or component.
They are similar to Project References in VB6.

HELP!!!!
• How do I get Help?
– F1 will get display context
sensitive help for the currently
selected object/word.
– Select Help from the menu
– Call your instructor at 1:00 a.m.
Initial Form Code
• You now have access to all of the code used to
create a Windows form (in the Windows Form
Designer generated code section).
• *** DON’T Mess around with it! ***
Initial Form Code
• Each Class, Subroutine or Region (an area you
define using #Region Name / # End Region) has
collapsers and expanders.
Microsoft Development Environment
Integrated Development Environment or IDE
VB 6 programmer -- VB.NET
Best to think of VB.NET as NEW language
with familiar syntax
.NET Framework Classes
Changes affect almost every aspect of .NET
Creating & working with forms & controls
arrays - string - etc….
