Introduction
The COIS 350 class is based on the Visual Basic program to give the students the opportunity
to open their minds to start writing programs. Although is being said that Visual Basic is a program for
“beginners”, it is a great program used by many professionals to develop many applications, games
and excellent visual graphics used by many educators to teach their curriculums in many universities
around the world.

History of Visual Basic
Visual Basic was born “BASIC” (Beginners All Purpose Symbolic Instruction Code)
created on its original prototype version in Dartmouth College on 1978. VB 1.0 was introduced
on 1991 by Alan Cooper and his company called Tripod. Cooper contracted with Microsoft to
develop it into Windows 3.0 under the code name Ruby. Ruby was an interface generator that
produced the visual part and was combined with Microsoft Omega data base and later became
the VBX interface. In September of 1992 Microsoft introduced it as Microsoft Visual Basic
Version 1 for MS-DOS until the end of its useful life in 1994. Version 2 was introduced in
November of 1992 for Windows base systems. Version 3 was released on 1993 with added tools
to control data bases and came in Standard and Professional versions. Visual Basic 4 was
released in 1995 with the new Windows 95 family of 32 bit operating systems. Visual Basic 6
was introduced in a package called Visual Studio 6.0 including Microsoft’s Visual C++
development systems and many organizations use this version today and Version 7 .NET was
introduced on February of 2002.

Components of Visual Basic
The Visual Basic IDE is made up of a list of components. These are; the Menu Bar, the
Tool Bar, the Project Explorer, the Properties Window, the Form Layout Window, the Toolbox,
the Form Designer and the Object Browser.

Algorithm
An algorithm is an effective list of well-defined instructions used for calculations, data
processing and automated reasoning. Beginning with an input, the instructions describe step by
step the process of execution proceeding through a number of successive states eventually
producing an output and terminating at an ending state.
Program
A computer program is a sequence of instructions written to perform a specified task in a
computer’s processor written on a specific language to enable a programmer to read it, study it
and develop it as necessary.
Programming Language
A programming language is design to express computations that can be performed by a
computer. It can also be used to create programs that control the behavior of a machine, express
algorithms precisely or as a mode of human communication.
Hardware
Hardware is the general term given to physical devices of a technology like the metal
parts and components of a computer.
Software
Software is a collection of computer programs and related data that provide the
instructions telling a computer what to do and how to do it.

Compiler
A compiler is a computer program that transforms a source code written in a high level
programming language into a lower level computer language or code to create an executable
program.
Logic Error
In computer programming, a logic error or a semantic error is a bug in the program that
causes it to operate incorrectly producing unintended or incorrect output but it does not to crash
or terminate abnormally.
Syntax Error
In computer science a syntax error refers to an error in the syntax of a sequence of
characters or tokens that is intended to be written in a particular programming language.

Sequential files
With sequential files, each element must be processed in turn. If you want to process a
particular record, you must read every record in the file in turn until you get to the one you want.
Sequential files are appropriate when you want to process most of the records in a file every time
you run your program. The mechanics of using sequential files are very similar to the mechanics
of using text files:
file variables declared
open, close files
file variable is first argument in I/O
Unlike text files, sequential files cannot be created or viewed with a text editor. They must be
created and displayed under program control.
Menu control
Menu control enables you to add functionality to your Web pages that is often used to
provide navigation. The Menu control supports a main menu and submenus, and allows you to
define dynamic menus sometimes called "fly-out" menus. This section includes information on
how to work with the Menu control to create navigation using static items and data from various
sources.

Crystal Reports
Crystal Reports for Visual Studio provides a highly productive way to create and
integrate interactive, presentation-quality reports into your Windows, Web or XML Web
Services applications. The embedded graphical designer lets you to easily create reports from
within your IDE and minimizes the intensive coding normally associated with report
development.

Conclusion
The Cois 350 class was one of its kind. The professor threw everything at us and we still
came out with a solution to her many challenges. I personally absorbed a lot of knowledge doing
my own research, watching many tutorial videos, trying over and over with Microsoft programs
that were not compatible with each other and even at the end having to replace my own home
computer starting from scratch again. I appreciate the Professor and some of our class mates
sharing their advance knowledge and guidance with me to make the process easier to complete.
It has been a lot of stress and frustrations but it has also been a lot of fun. I am looking forward
to my next Cois class.
