o Looping allows us to run a group of statements repeatedly.

o Some loops repeat statements until a condition is False;

o Others repeat statements until a condition is True.

o There are also loops that repeat statements a specific number of times.

The following looping statements are available in VBScript:

• Do...Loop: Loops while or until a condition is True.
• While...Wend: Loops while a condition is True.
• For...Next: Uses a counter to run statements a specified number of times.
• For Each...Next: Repeats a group of statements for each item in a collection or each element of an array.

9.1 Using Do Loops

We can use Do...Loop statements to run a block of statements an indefinite number of times. The statements are repeated either while a condition is True or until a condition becomes True.

9.1.1 Repeating Statements While a Condition is True

Repeats a block of statements while a condition is True or until a condition becomes True

a) Do While  condition

    Statements

    -----------                 

    -----------

    Loop 

Or, we can use this below syntax:

Example:

Dim x

Do While x<5 x="x+1

            Msgbox "Hello G.C.Reddy"

            Msgbox "Hello QTP"

Loop

b) Do 

    Statements

    -----------                 

    -----------

    Loop While  condition

Example:

Dim x

x=1

Do  

 Msgbox "Hello G.C.Reddy"

 Msgbox "Hello QTP"

  x=x+1

Loop While x<5

9.1.2 Repeating a Statement Until a Condition Becomes True

c) Do Until  condition

    Statements

    -----------                 

    -----------

    Loop 

Or, we can use this below syntax:

Example:

Dim x

Do Until x=5 x=x+1

 Msgbox "G.C.Reddy"

 Msgbox "Hello QTP"

Loop

Or, we can use this below syntax:

d) Do 

    Statements

    -----------                 

    -----------

    Loop Until condition

Or, we can use this below syntax:

Example:

Dim x

x=1

Do

Msgbox "Hello G.C.Reddy"

Msgbox "Hello QTP"

x=x+1

Loop Until x=5

9.2 While...Wend Statement

Executes a series of statements as long as a given condition is True.

Syntax:

While  condition

    Statements

    -----------                 

    -----------                      

Wend

Example:

Dim x

x=0

While x<5 x=x+1

msgbox "Hello G.C.Reddy"

msgbox "Hello QTP"

Wend

9.3 For...Next Statement

Repeats a group of statements a specified number of times.

Syntax:

For counter = start to end [Step step]

statements

Next

Example:

Dim x

For x= 1 to 5 step 1

Msgbox "Hello G.C.Reddy"

Next

9.4 For Each...Next Statement

Repeats a group of statements for each element in an array or collection.

Syntax:

For Each item In array

Statements

Next

Example:

Dim a,b,x (3)

a=20

b=30

x(0)= "Addition is "& a+b

x(1)="Substraction is " & a-b

x(2)= "Multiplication is " & a*b

x(3)= "Division is " & a/b

For Each element In x

msgbox element

Next

Example:

MyArray = Array("one","two","three","four","five")
For Each element In MyArray
msgbox element
Next
