Arrays VBScript:

Arrays are two types – Static Array & Dynamic Array

ARRAY:

Array is a collection of data with different types of data type.

Syntax:
1
Dim ArrayName(size)

Where, “ArrayName” is the unique name for the array and “size” is a numeric value that indicates the number of elements in the array dimension within the array.

Example:
1
Dim arrayvalue(3)

It stores 4 values. The array always starts from 0.

Assigning values to the array:

1
2
3
4
arrayvalue (0) = 1
arrayvalue (1) = 2
arrayvalue (2) = 3
arrayvalue (3) = 4

There are two types of arrays: 1. Static Array, 2. Dynamic Array.

Static Array:

It has a specific number of elements. Once assigned, size of a static array can’t be modified at runtime.

Dynamic Array:

Size of a dynamic array can be modified at runtime.

Lower Bound & Upper Bound of Array:

1
2
3
Dim arrayvalue(3)
Msgbox lbound(arrayvalue)
Msgbox ubound(arrayvalue)

Size of the Array:

1
2
Dim arrayvalue(3)
Msgbox “The array size is ”& Ubound(arrayvalue) + 1

Another way to assigning Array:

Syntax:
1
array(arglist)
Example:
1
2
3
4
5
6
7
Dim arrayvalue
Arrayvalue = array(91,92,93,94)
Msgbox Ubound(arrayvalue)
Msgbox Arrayvalue(0)
Msgbox Arrayvalue(1)
Msgbox Arrayvalue(2)
Msgbox Arrayvalue(3)

REDIM:

It recreates the array and erases all the old data

PRESERVE:

Preserve should be used along with redim. It will retain the old data.

SINGLE DIMENSION ARRAY:

1
2
3
4
5
Dim arrayvalue(1)
arrayvalue(0)=10
arrayvalue(1)=20
msgbox arrayvalue(0)
msgbox arrayvalue(1)

MULTI DIMENSION ARRAY:

1
2
3
4
5
6
7
8
9
Dim arrayvalue(1,1)
arrayvalue(0,0)=10
arrayvalue(0,1)=20
arrayvalue(1,0)=30
arrayvalue(1,1)=40
msgbox arrayvalue(0,0)
msgbox arrayvalue(0,1)
msgbox arrayvalue(1,0)
msgbox arrayvalue(1,1)
