Variable Declaration and Scope

In PowerShell, variables are declared with a $ prefix, and their scope can be defined explicitly. In VBScript, variables are declared using the Dim, Public, or Private keywords without a prefix.

PowerShell Example:

$myVariable = "Hello, World!"

VBScript Example:

Dim myVariable
myVariable = "Hello, World!"

Function Definitions

PowerShell uses the function keyword to define functions, while VBScript uses the Function keyword. The return value handling also differs.

PowerShell Example:

function Get-Greeting {
    return "Hello, World!"
}

VBScript Example:

Function GetGreeting()
    GetGreeting = "Hello, World!"
End Function

Error Handling

PowerShell uses try, catch, and finally blocks for error handling, while VBScript uses On Error Resume Next and checks the Err object.

PowerShell Example:

try {
    # Code that may throw an error
} catch {
    Write-Host "An error occurred: $_"
}

VBScript Example:

On Error Resume Next
' Code that may throw an error
If Err.Number <> 0 Then
    MsgBox "An error occurred: " & Err.Description
End If

Object Manipulation

PowerShell is built on .NET and has rich support for object manipulation, while VBScript has limited support for objects.

PowerShell Example:

$person = New-Object PSObject -Property @{ Name = "John"; Age = 30 }

VBScript Example:

Set person = CreateObject("Scripting.Dictionary")
person.Add "Name", "John"
person.Add "Age", 30

Array Handling

PowerShell arrays are more flexible and can hold different types, while VBScript arrays are more rigid.

PowerShell Example:

$array = @(1, "two", 3.0)

VBScript Example:

Dim array(2)
array(0) = 1
array(1) = "two"
array(2) = 3.0

Conditional Statements

PowerShell uses if, elseif, and else, while VBScript uses If, ElseIf, and Else.

PowerShell Example:

if ($condition) {
    Write-Host "Condition is true"
} elseif ($otherCondition) {
    Write-Host "Other condition is true"
} else {
    Write-Host "Condition is false"
}

VBScript Example:

If condition Then
    MsgBox "Condition is true"
ElseIf otherCondition Then
    MsgBox "Other condition is true"
Else
    MsgBox "Condition is false"
End If

Loop Constructs

PowerShell supports various loop constructs, including foreach, for, and while, while VBScript has For, For Each, and Do While.

PowerShell Example:

foreach ($item in $array) {
    Write-Host $item
}

VBScript Example:

For Each item In array
    MsgBox item
Next

Cmdlets vs. Built-in Functions

PowerShell uses cmdlets for command execution, while VBScript relies on built-in functions. This leads to significant differences in how tasks are performed.

PowerShell Example:

Get-Process

VBScript Example:

Set objWMIService = GetObject("winmgmts:\\.\root\cimv2")
Set colProcesses = objWMIService.ExecQuery("Select * from Win32_Process")
For Each objProcess in colProcesses
    MsgBox objProcess.Name
Next

String Manipulation

PowerShell has rich string manipulation capabilities, including string interpolation, while VBScript has more limited options.

PowerShell Example:

$name = "John"
$message = "Hello, $name!"

VBScript Example:

name = "John"
message = "Hello, " & name & "!"

File I/O Operations

PowerShell provides cmdlets for file operations, while VBScript uses the FileSystemObject.

PowerShell Example:

Get-Content "C:\path\to\file.txt"

VBScript Example:

Set fso = CreateObject("Scripting.FileSystemObject")
Set file = fso.OpenTextFile("C:\path\to\file.txt", 1)
Do While Not file.AtEndOfStream
    MsgBox file.ReadLine
Loop
file.Close
