Programming involves the study of computer languages like Visual Basic (VB), which is a tool created by Microsoft to build graphical user interface (GUI) applications. VB uses flowcharts, algorithms, variables, operators, and loops. Basic VB methods include activate, click, and load. Common data types are integers and strings. Variable functions include inputbox, messagebox, msgbox, DIM, print, and Val. Basic VB operations can be demonstrated using an example that activates a form, gets input using inputbox, performs addition, and prints the result.

1. Introduction to programming
What is programming ?
Programming – deal with the study of
computer language
What is a visual basic ?
Visual Basic (VB) – is a tool created by
Microsoft to build a computer
application in a user – friendly
environment that supports Graphical
User Interface
GUI - Graphical User Interface
Flowchart – A graphical representation
of step by step instructions to solve a
problem
Algorithm – a set of step by step
instruction to solve a problem

2. Operator – An erqine used to perform
logical and mathematical operation
Variable – A Memory storage / container
Loop – An action that reqeatedly and
continuously perform until a certain
condition is done
Operator:
1) Arithmeti cope rators
+  Addition
-  Subtraction
*  Multipication
/  Division
2) Relational Operatior
>  greater than
<  less than
>=  greater than or equal to

3. <=  less than or equal to
=== or==or=  equal to
<>or!=  not equal to
3) logical operators
Il  OR &&  and
flowchart algorithm variables
Preparation 1)x=5 2)x=5
Y=6 y=6
Z=x+y z=x+y

4. Is Z less than
100?
Is ? less than
100?
Yes or no
If true , re-start
the operation
Else if false

5. Basic Method in Visual Basic
1. Activate
2. Click
3. Load
Basic Data Types
1. integer -1,2,3,4,5,6,7,8,9,0
2. String – a-z and other characters
Variable functions
1. inputbox
2. messagebox
3. msgbox
4. DIM
5. Print
6. Val

6. Basic Operation Visual basic
programming
Ex. 1. Activate Method
Library or
storage
Private Sub Form Activate []
--------------------------
X = inputbox [“”]
Y = inputbox [“”]
Z = x+y for Conditional
Statement

7. Print z
End Sub
