What is VBScript?

 VBScript is a scripting language.

As with algebra, VBScript variables are used to hold values or expressions.

Rules.

• Must begin with a letter

• Cannot contain a period (.)

• Cannot exceed 255 characters

Basic Functions:

VBScript MsgBox Function

The MsgBox function displays a message box and waits for the user to click a button

and then an action is performed based on the button clicked by the user. 

Example: MsgBox("Welcome") 

VBScript InputBox Function

The InputBox function displays a dialog box, where the user can write some input

and/or click on a button. If the user clicks the OK button or presses ENTER on the

keyboard, the InputBox function will return the text in the text box. If the user clicks

on the Cancel button, the function will return an empty string (" ").

dim fname

fname=InputBox("Enter your name:")

MsgBox("Your name is " & fname)

VBScript Operators.

In VBScript, operators are used to perform an operation. For example, an

operator could be used to assign a value to a variable. An operator could also

be used to compare two values. 

Artithmetic Operator

Operator               Description

+                            Addition

-                             Subtraction

*                             Multiplication

/                              Division

\                              Integer Division (divides 

                               two numbers and returns 

                               an integer result)

Mod                        Modulus (remainder of a 

                               division)

^                             Exponentiation (raises the 

                               number to the power of 

                               an exponent)

Operator Description

=             Assign

Comparison Operators

Operator Description

=              Is equal to

<>            Is not equal to

>              Greater than

>=            Greater than or equal to

<              Less than

<=            Less than or equal to

Logical Operators

Operator                           Description

And                                   Performs a logical 

                                          conjunction on two 

                                          expressions (if

                                          both expressions 

                                          evaluate to True, 

                                          result is True. If

                                          either expression 

                                          evaluates to False, 

                                          result is False)

Or                                      Performs a logical 

                                          disjunction on two 

                                          expressions (if

                                          either or both 

                                          expressions 

                                          evaluate to True, 

                                          result is True).

Not                                    Performs logical 

                                          negation on an 

                                          expression.

Xor                                    Performs a logical 

                                          exclusion on two 

                                          expressions (if

                                          one, and only one, 

                                          of the expressions 

                                          evaluates to True, 

                                          result is True. 

                                          However, if either 

                                          expression isNull, 

                                          result is also Null).

Concatenation Operators

Operator           Description

&                       Concatenate (join two strings 

                          together)

+                        Adds two numbers together
