Class 8 - Introduction to Visual Basic

Visual Basic

Visual basic was derived from the language BASIC.

BASIC has its own limitations., it is a simple programming language but used only in a text based environment. But visual basic is

User friendly

Supports Graphical User Interface(GUI)VB

VB is an Event- driven programming, which means the flow of the program is determined by an Event.

An Event is an action performed either by mouse click, double click or pressing keys on the keyboard.

Integrated Development Environment describes the interface and the environment we use to create our own applications.

Class 7 : Introduction to HTML

HTML

HTML (Hyper Text MarkUp Language) is used to create web pages. The codes are called tags. The tags are given within < and >.

There are two types of tags ,

i. Container Tag : It has both opening and closing tags.
e.g : <html> </html>

ii. Empty Tag : It has only a opening tag.
e.g :

The basic structure of a HTML document is

<html>

<head>

<title>

</title>

</head>

<body>

………

……..

</body>

</html>

Whatever is typed between <title> and </title> will be displayed on the title bar not in the web page.

<html>

</head>

<body>
Your text goes here.

</body>

</html>

Example 1 :
<html>
<head><title> My Page BCBS</title>
</head>
<body>
Bishop Cotton Boys' School
</body>
</html>

The output will be :

The data entered between <body> and </body> only will be displayed in the web page.
Line break tag :
It moves the cursor to the next line.
Paragraph Tag :
It leaves a blank line.

Example 1 :
<html>
<head><title> My Page BCBS</title>
</head>
<body>
BCBS 
Thomas House 
Pope House 
Elphick House 
Pakenham Walsh House 
Pettigrew House
</body>
</html>

The output will be :

Class 8 - Repetition Programming(For)

Loops

If we want to repeat a set of statements , looping statements are used.

There are two types :

For ... Next
Do ....Loop

For ... Next

Probably this is the easiest of the looping statements. The general form is given as

For variable=initial value to final value step value
--------------
-------------
Next variable

1. Display the numbers from 1 to 10.

Dim a as integer
For a=1 to 10
Print a
Next a

Note :

Step value is used to increment or decrement . In the above program it should have been Step 1, since the difference between two numbers is 1. But Step 1 is the default value so no need to write it.

2. Display the even numbers from 5 to 50

Dim a as integer
For a=6 to 50 step 2
Print a
Next a
3. Display the following numbers:
     100
     90
     80
     ....
     ....
     10

Dim a as integer
For a=100 to 10 step -10
Print a
Next a
Note :
Here the numbers are in descending order , therefore step -10.
