10
Class Goals (continued)

1. Will work with a number of method attributes such
   as WebMethod, Serializable, Synchronization,
   Locking, etc.
2. Some exposure to advanced subject like
   multi-threaded applications, tree controls,
   remoting, etc.

Course Notes

• While students will write a simple windows
  console application using a text editor the
  course will primarily focus on programming
  windows desktop and web based applications using
  the Visual Studio.NET IDE (Interactive
  Development Environment).
•  

12
Course Notes (cont)

• The course will use Visual Basic.NET, version
  1.0, although the student will still be able to
  complete the class using the new released version
  of Visual Basic.NET 2003, version 1.1.
•  

13
Course Notes (cont)

• Each class will open with a time for questions
  and answers. Questions from a previous class or
  questions emailed to the instructor will be
  addressed. Other questions will either be
  answered or captured for a future response.
  Questions should be as specific as possible.
•  
• The only dumb questions are the ones not asked!

Effective Learning

• First is Doing
• Class exercises
• Coaching
• Helping each other
• Homework
• Second is Discussing
• Class discussions
• Asking questions
• Sharing ideas and information
• Last is Listening

17
You have my permission, if what I'm doing is
boring or just not working, let me know and we'll
try something different.
18
Class Attendance

• Class attendance is important.
• While missing a class is sometimes unavoidable,
  it can put you behind for the rest of the course.
• Class Material tends to build on prior lessons.
• All class material is available on the web.
•  

19
Grades

• Average of Homework Assignments (probably seven)
  and a Web Services Class Project.
• I tend to grade by developing a grade matrix for
  an assignment and then assigning grades based on
  completeness, so please follow the directions.

20
Late Homework

• While late homework is sometimes unavoidable, but
  my experience is that it comes with a price.
•  
• While incompletes are allowed with prior approval
  of the instructor they are clearly not a good
  idea.
•  

21
Every attempt will be made to provide each
student with a level of instruction and material
able to insure a successful learning
experience.If you are having any difficulty
with the material or the instructor please
contact the instructor or the Office of
Continuing Education for assistance.
22
Your Introductions

• A bit about yourself, why you are here
• Your programming background (operating systems,
  languages, ?)
• Any exposure to .NET ? Other .NET courses ?
• Your expectations for this course

23
Tonight ? HelloWorld in three flavors

1. Creating a Visual Basic.NET program without using
   Visual Studio.NET (use Notepad instead)
2. Writing a console Hello World using the IDE
   (Integrated Development Environment) ? Visual
   Studio.NET
3. Writing a Windows Form Hello World using Visual
   Studio.NET

24
Creating a Visual Basic.NET program without using
Visual Studio.NET
25
Steps to Creating a Non-Visual Studio.NET Program

1. Open a Command (MSDOS) Window in the target
   directory
2. Select or create a directory to work in
3. Use Notepad (or someother text editor) to write
   the code and save it in the target directory
4. Run an Frameworks SDK provided batch file to
   setup the environment
5. Compile your program
6. Correct any errors
7. Execute your program

26
Step 1 - Open a Command (MSDOS) Window in the
target directory

• Under the start menu
• Programs ? Accessories ? Command Prompt

27
Step 2 - Select or create a directory to work in

1. Open a Command Window
2. C\Documents and Settings\Chipgtcd k\
3. K\gtmkdir VBClassConsoleApp or whatever...
4. K\gtcd VBClassConsoleApp

28
Step 3 - Use Notepad (or some other text editor)
to write the code and save it in the target
directory

• Enter the following code
• Module HelloWorld
• Sub Main() System.Console.WriteLine("Hello
  World")
• End Sub
• End Module
• Save the file it in the target directory with the
  name followed HelloWorld.vb

29
Step 4 - Run an Frameworks SDK provided batch
file to setup the environment

• Microsoft Provides Several Batch Files to Set Up
  a Command Window Environment for the .NET
  Frameworks SDK
• vsvars32.bat (..SDK\Common7\Tools\..)
• corvars.bat (..FrameworkSDK\Bin\..) for Version
  1.0
• sdkvars.bat (..SDK\V1.1\Bin\..) for Version 1.1
• Probably the easiest way to do this is to copy
  the file to your target directory and then
  execute it (i.e. type filename and hit return) in
  the Command window.

30
Step 5 - Compile your program

• Within the command window
• Type vbc program name
• K\VBClassConsoleAppgt vbc HelloWorld.vb

31
Step 6 - Correct any errors

1. Identify the error
2. Return to the Notepad window and correct the code
3. Save the program
4. Try Step 5 again

32
Step 7 - Execute your program

• Within the command window
• Type the program name
• K\VBClassConsoleAppgt HelloWorld (.exe is
  optional)
• You should see something like this
• K\VBClassConsoleAppgt HelloWorld
• Hello World
• K\VBClassConsoleAppgt

33
A Few Comments About the Code

• Module HelloWorld
• Sub Main() System.Console.WriteLine("Hello
  World")
• End Sub
• End Module
• Module and matching End Module
• Sub or Function (functions return a value) and
  End Sub
• Method called main (every console application
  includes a main method)

34
System.Console.WriteLine("Hello World")

• System is the Namespace
• Can be nested
• System.Windows.Forms
• Namespace can be referenced using an Imports
  statement
• Console is the Class in the Namespace
• WriteLine is a method in the class

35
Try Using the Imports Statement

• Two Differences in this Code
• Addition of the Imports Statement
• Remove of the System before Console
• Imports System
• Module HelloWorld
• Sub Main()
• Console.WriteLine("Hello World")
• End Sub
• End Module
