Declaring C# like Class type

Basically, if you are familiar with C# programming language, you will find it quite straight forward to do this in Powershell.

The following sample code explains the basic of declaring class in PowerShell:

# references:
#  https://devblogs.microsoft.com/scripting/powershell-5-create-simple-class/
#  https://xainey.github.io/2016/powershell-classes-and-concepts/

# declare a new object type - the same way like C#
class MyObject {

    # instance fields
    [string]$name
    [string]$code
    [int32]$age
   
    # static fields
    static [int]$objCount


    # constructor
    MyObject ([string]$n){
        $this.name = $n

        # increase the number of instance that has been created.
        [MyObject]::objCount++;
    }

    [string]ToString() {
        #return $this.name
        return "Hello {0}!" -f $this.name
    }

}

# instantiate new instance

##$o = New-Object MyObject "tester"
$o = [MyObject]::new("tester")

##$o.name = "mike"
$o.code = "m001"
$o.age = 38

#show the contents
$o

Write-Host "instance count=$([MyObject]::objCount)"

$s = $o.ToString()
Write-Host "$s"

$j = $o | ConvertTo-Json
Write-Host $j

Scheduled task in Windows Task Scheduler - part 3

This is the last part of Task Scheduler - security context which is created using New-ScheduledTaskPrincipal. Usually, we are using S4U logon type for any server scheduled task + Highest Run Level. S4U details as per MS documentation: Use an existing interactive token to run a task. The user must log on using a service for user (S4U) logon. When an S4U logon is used, no password is stored by the system and there is no access to either the network or encrypted files. You can find more information in this page:     https://docs.microsoft.com/en-us/windows/win32/taskschd/principal-logontype For any user ID that you specified to run the scheduled task, it requires "Log on as a batch job" or "Log on as a service". You can find the details here:     https://docs.microsoft.com/en-us/windows/security/threat-protection/security-policy-settings/log-on-as-a-batch-job     https://docs.microsoft.com/en-us/windows/security/threat-protection/...

Create scheduled task in Windows Task Scheduler

Windows Task Scheduler is a utility that helps to execute any process periodically. For example, you want to sync your working files on daily basis, scanning virus, process some data, etc. A task has the following components: Action or multiple actions - which is the process that you want to run periodically. We use New-ScheduledTaskAction to create new action object. Trigger - which is the time to run the process and it can have multiple timing. We use New-ScheduledTaskTrigger to create new trigger. Security context - any process must run in a valid security context. We can set the context using New-ScheduledTaskPrincipal. The following script creates an on demand task which requires user to manually trigger the task. $task_folder = "\myTasks\" $task_name = "myTask2" # this can be any Powershell script. $ps_script_file = "d:\temp5\test-script.ps1" ## The first line will show err if $task_folder does not exist. ## The second line will not...
