PowerShell Script To Generate an Input Box

# PowerShell Read-Host Input Box
Clear-Host
$YearCalc = Read-Host "When were you born?"
$Now = (Get-Date -uformat "%Y") -$YearCalc
$Maybe = $Now -1
Write-Host "You are $Maybe or $Now years old "

Input Box Read-Host

Note 1:  $YearCalc is the variable that holds the value you enter into the input box.

Note 2: I am sure that you can do better with the math and with the logic.

Guy Recommends: Free WMI Monitor for PowerShellSolarwinds Free WMI Monitor for PowerShell

Windows Management Instrumentation (WMI) is one of the hidden treasures of Microsoft's operating systems.  Fortunately, SolarWinds have created a Free WMI Monitor so that you can discover these gems of performance information, and thus improve your PowerShell scripts.

Take the guess work out of which WMI counters to use when scripting the operating system, Active Directory, or Exchange Server. Give this WMI monitor a try - it's free.

PowerShell's Read-Host Parameters

# PowerShell Read-Host Parameters
Clear-Host
Get-Help Read-Host -full

If you want a more secure input box, try -AsSecureString this will displays asterisks (****) in place of the characters that the user types in the box.   You could also experiment with -prompt.

Creating a Pop-up Message

Here is a technique where PowerShell creates a ComObject, which in turn, has a method to produce a pop-up message.

$WshShell = New-Object -ComObject wscript.shell
$Time = Get-Date -UFormat %R
$Message ="Test for $Env:computername at: " + $Time
$PopUp = $WshShell.popup("$Message",0,"Task Scheduler Pop-up",1)

This freeware monitor is great for checking whether your network's load-balancing is performing as expected, for example, are two interfaces are getting about equal traffic?

It's easy to install and straightforward to configure. You will soon be running tests to see how much network bandwidth your applications consume.

The GUI has a lovely balance between immediate network traffic data in the middle, combined with buttons to seek related data and configuration settings. Give this monitor a try, it's free!

Here is PowerShell Script to Check for a Process

The concept is to produce a message box if a named process (iExplore) is actually running as reported in Task Manager.

# PowerShell script to test if a program is running.
Clear-Host
$i =1
$Victim = "iExplore"
# PowerShell function to produce the payload function
function Output-MsgBox
{
$WshShell = New-Object -ComObject wscript.shell
$Message ="$Victim is running "
$PopUp = $WshShell.popup("$Message",0,"Your Alert ",1)
}

# Test if a list of processes contains a particular item
For (1..1000) {
$Alerty = Get-Process
if($Alerty.ProcessName -Contains $Victim) {
Output-MsgBox; Start-Sleep 100}
Else {Write-Host "No $Victim $i";Start-Sleep 10} $i++
}

Note 3: I recommend you change this line in your script:
$Victim = "iExplore"

Note 4: This script is ripe for modifying, particularly in finessing the 'If.. else' logic.

You may already know about Write-Host and Clear-Host (cls), but there is also Out-Host.  PowerShell -Noun or -verb research always throws up at least one surprise.
