1. VB Script V B S

2. VB Scripting Basics B S V
VBScript stands for Visual Basic Scripting, is a
scripting language was launched by Microsoft in1996.
VB Scripting language is a lightweight programming
language.
VBScript can be used to write both client-side and
server-side scripting.
VBScript is a light version of Microsoft's
programming language Visual Basic
VBScript is only supported by Microsoft's browsers
(Internet Explorer) V B S

3. Data Types
VBScript supports only one data type called ‘Variant’.
The variant data type is a special kind of data type
that can contain different kinds of information.
It is the default data type returned by all functions in
VB Script.
A variant behaves as a number when it is used in a
numeric context and as a string when used in a string
context. V B S

4. VB Script Variables B S V
A variable is a "container" /Placeholder that refers to a memory location, that stores program information that may change at run time.
As with algebra, VBScript variables are used to hold
values or expressions.
A variable can have a short name, like x, or a more
descriptive name, like carname. V B S

5. Rules for VBScript variable names
Must begin with a letter 
Cannot contain a period (.)
Cannot exceed 255 characters
In VB Script, all variables are variant data type, that can
store different types of data. V B S

6. Declaring (Creating) VBScript Variables
Creating variables in VBScript is most often referred to as "declaring" variables.
You can declare VBScript variables with the Dim, Public or the Private statement. Like this:
- Dim x
- Dim carname V B S

7. VB Script Array Variables
An array variable is used to store multiple values in a single
variable.
In the following example, an array containing 3 elements is
declared:
Ex: Dim names(2)
The number shown in the parentheses is 2. We start at zero
so this array contains 3 elements. This is a fixed-size array.
You assign data to each of the elements of the array like
this:
names(0)="Tove“
names(1)="Jani" names(2)="Stale" V B S

8. VB Script has two kinds procedures:
VB Script Procedures
Ex:
Sub kumar()
msgbox "kumar"
End Sub
kumar()
VB Script has two kinds procedures:
1.) Sub procedure
2.) Function procedure
1.) Sub procedure:
Sub procedure is a series of statements, enclosed by the Sub and End Sub statements can perform actions, but does not return a value can take arguments. V B S

9. VBScript Function Procedures
Ex:
function myfunction()   myfunction=Date() end function
Is a series of statements, enclosed
by the Function and End Function
statements.
Can perform actions and can
return a value.
Can take arguments that are
passed to it by a calling procedure.
Without arguments, must
include an empty set of
parentheses ().
Returns a value by assigning
a value to its name.

10. Conditional Statements
Conditional statements are used to perform different actions for different decisions.
In VBScript we have four conditional statements:
If statement - executes a set of code when a condition is true
If...Then...Else statement - select one of two sets of lines to execute
If...Then...ElseIf statement - select one of many sets of lines to execute
Select Case statement - select one of many sets of lines to execute V B S

11. If...Then...Else
Use the If...Then...Else statement if you want to
Execute some code if a condition is true
Select one of two blocks of code to execute
If you want to execute only one statement when a condition is true,
you can write the code on one line:
Ex: Function greeting()
i=hour(time)
msgbox i
If i < 10 Then
msgbox "Good morning!"
Else
msgbox "Have a nice day!"
End If
End Function
greeting() V B S

12. Select Case
You can also use the "Select Case" statement if you want to select one of many blocks of code to execute:
Select Case d   Case 1    msgbox "Sleepy Sunday"   Case 2     .write("Monday again!")   Case 3     document.write("Just Tuesday!")   Case 4     document.write("Wednesday!")   Case 5     document.write("Thursday...")   Case 6     document.write("Finally Friday!")   Case else     document.write("Super Saturday!!!!") End Select V B S

13. VB Script Operators B S V
Operators are used to "do operations" or manipulate
variables and values.
For example, addition is an example of a
mathematical operator and concatenation is an
example of a string operator.
The plus sign "+" is the operator used in
programming language to represent this
mathematical addition operation. V B S

14. Math Operators
When you want to perform addition, subtraction, multiplication, and other mathematical operations on numbers and variables use the operators listed below. V B S

15. B S Comparison Operators Comparison Operators V
When you want to compare two numbers to see
which is bigger, if they're equal, or some other
type of relationship use the comparison operators
listed below.
Common uses of comparison operators are within
conditional statements like an If Statement or the
condition check in a While Loop. V B S

16. Logical operators B S manipulate and create logical
Logic operators are used to
manipulate and create logical
statements. For example if
you wanted a variable
shoeSize to be equal to 10 or
11 then you would do
something like: V B S

17. String Concatenation Operator
When you have
various strings that
you would like to
combine into one string
use the concatenation
operator. V B S
