Do you need something to let your end-user know what’s going on? Don’t want your end-user to see the program running? Well, PowerShell has the ability to use the system windows notify system. AKA, the message box that pops up on the right of the screen.
The first step to make this happen is we need to add the assembly, system.windows.forms. We do this by the amazing command add-type.
add-Type -AssemblyName System.Windows.Forms
Now we have the assemblies loaded into ram, we need to create an object from those assemblies. This way we can command the object later. We do this using the New-object cmdlet. We want the notification tray icons. So we want the system.windows.forms.notifyicon.
$global:balloon = New-Object System.Windows.Forms.NotifyIcon
You know that notifications have icons. Yep, It’s from the application itself. So, if you have this function in another application, it will show that the application’s icon. We call upon the System.Drawing.Icon to do this. But First, we need to know which app we are currently using. We do this with Get-Process with the ID and the current Pid.
$path = (Get-Process -id $pid).Path
$balloon.Icon = [System.Drawing.Icon]::ExtractAssociatedIcon($path)
What’s cool about this is we are extracting the icon of the application itself with that extract associated icon. We push it into our notify icon object. Next, we want to add the Tip Icon. That’s the ! ? so on and so forth. We do this by using the system.windows.forms.tooltipicon function. Believe it or not, we can use a validate set in the parameters to get the exact naming input as well. The property of the object is BalloonTipIcon.
$balloon.BalloonTipIcon = [System.Windows.Forms.ToolTipIcon]::$Messagetype
Now the message itself. At this point we have an icon, the notification icon and that’s it. This is the meat of the notification. The propriety in the balloon object is, BalloonTipText.
$balloon.BalloonTipText = $Message
Just a quick note, to much text is ugly.
Next is the title, I like to use just the word attention as it brings the users eyes to it. The balloon’s propriety for this is BalloonTipTitle.
$balloon.BalloonTipTitle = "Attention"
Finally, we want to make this thing visible. An invisible tooltip is as useful as invisible ink without a black light. As you have guessed by now, Visible is the balloon’s propriety.
Now the drum roll, please! It’s time to show our masterpiece that will be enjoyed by the end-user for a split second. The ShowBalloonTip(). Yes, let us do it! This is a method and will show the balloon tip for x time. This is set up in milliseconds. So, every 1000 milliseconds makes a second.
$balloon.ShowBalloonTip($Time)
Lets put it all together shall we. Behold the script of the balloon tip.
The Script
Function Invoke-SHDBallonTip {
[cmdletbinding()]
param (
[string]$Message = "Your task is finished",
[int]$Time = 10000,
[validateset("Info", "Warning", "Error")][string]$Messagetype = "Info"
)
#Adds the reqruired assembly's for the ballon tips.
Add-Type -AssemblyName System.Windows.Forms
#Creates the notifiy icon that will appear in the notification tray.
$global:balloon = New-Object System.Windows.Forms.NotifyIcon
$path = (Get-Process -id $pid).Path
$balloon.Icon = [System.Drawing.Icon]::ExtractAssociatedIcon($path)
$balloon.BalloonTipIcon = [System.Windows.Forms.ToolTipIcon]::$Messagetype
$balloon.BalloonTipText = $Message
$balloon.BalloonTipTitle = "Attention"
$balloon.Visible = $true
$balloon.ShowBalloonTip($Time)
}
That’s it, folks. Such a simple thing. Here are a few things you can do. You can change the $path to $Path = Get-Process -id $PID. Then in the balloon.icon, use $path.path. In the balloon tip title, you can put $path.description and now you have the description as the title. Other than that, it’s pretty straight forward.
I would love to hear back from yall. Let me know if there is anything you would like for me to write about.

This will seem dumb, but do you need a message box in your script? Normally no, but when you are using a script for an end-user, you might need it. So, let us take a look at how to do it real quick.
The Script
function Invoke-SHDMessageBox {
[cmdletbinding()]
param (
[Parameter(HelpMessage = "Message Title", Mandatory = $true)][Alias('Title', 'header')][string]$MessageTitle,
[Parameter(HelpMessage = "Message Body", Mandatory = $true)][Alias('Boby', 'Information')][string]$MessageBody,
[Parameter(HelpMessage = "Message Buttons", Mandatory = $true)][Alias('Buttons')][validateset("YesNo", "YesNoCancel", "OK", "OKCancel")][string]$MessageButtons,
[Parameter(HelpMessage = "Message Image", Mandatory = $true)][Alias('Image')][validateset("Asterisk", "Error", "Exclamation", "Hand", "Information", "None", "Question", "Stop", "Warning")][string]$Messagetype
)
Add-Type -AssemblyName PresentationCore, PresentationFramework
$ButtonType = [System.Windows.MessageBoxButton]::$MessageButtons
$MessageIcon = [System.Windows.MessageBoxImage]::$Messagetype
$Results = [System.Windows.MessageBox]::Show($Messageboxbody, $MessageboxTitle, $ButtonType, $messageicon)
Return $Results
}
The Breakdown
Lets break this guy down. First thing first, the parameters.
- MessageTitle – What will be presented as the title of the message box.
- MessageBody – The message itself.
- MessageButtons – What types of buttons.
- YesNo
- YesNoCancel
- OK
- OKCancel
- MessageType – The type of image will be presented.
All the parameters are mandatory. None can be passed by the pipeline. All are single strings instead of my normal list of strings. It’s far easier that way.
Next, we need to add the assembly for the box. These are PresentationCore and PresentationFramework.
Add-Type -AssemblyName PresentationCore, PresentationFramework
Next, we just add items to the variables we will be using. The input from the parameters and their validate set. For the buttons themselves we call upon the power of the assembly we added earlier. [System.Windows.*] In the button case, the * becomes MessageBoxButton.
$ButtonType = [System.Windows.MessageBoxButton]::$MessageButtons
Then the message box image will be the same way, but with messageboximage.
$MessageIcon = [System.Windows.MessageBoxImage]::$Messagetype
Then we put it all together with the messagebox itself.
$Results = [System.Windows.MessageBox]::Show($MessageBody, $MessageTitle, $ButtonType, $messageicon)
The first part of the show is the body followed by the title, then followed by the buttons, and finally the image. Notice I pipe it into Results. I do this because we want to return those results.
That’s it! Once you return the results, you can test them with an if statement. Come back Monday for a ballon notification function.

I wanted to share a little script that has changed the world at my current company. It’s a simple password email notification script. What it does is grabs the users’ whos passwords about to expire. Then it emails that user with instructions on how to reset their password. Then it sends an email to the user’s manager with a list of when the user’s password will expire. Then finally it sends an email to another person with a complete list of all expiring users and when they will expire. After the user hits zero, the script no longer cares about that person. This is to prevent lots of headaches in the long run with on leave and whatnots. The best thing to do is to set up a scheduled task on a server with rsats. The computer will also need a relay setup on the exchange server.
The Script
param (
[parameter(Helpmessage = "Return Email", Mandatory = $true)][string]$ReturnEmail,
[parameter(Helpmessage = "Email Sent to IT", Mandatory = $true)][string]$ITEmail,
[parameter(Helpmessage = "Mail Server", Mandatory = $true)][string]$MailServer,
[parameter(Helpmessage = "Employee Organizational Unit", Mandatory = $true)][string]$EmployeeOU,
[parameter(Helpmessage = "Training Link", Mandatory = $true)][string]$TrainingLink,
[parameter(Helpmessage = "Training Link", Mandatory = $true)][string]$DaysWithinExpiration
)
$MaxPwdAge = (Get-ADDefaultDomainPasswordPolicy).MaxPasswordAge.Days
$expiredDate = (Get-Date).addDays(-$MaxPwdAge)
$emailDate = (Get-Date).addDays( - ($MaxPwdAge - $DaysWithinExpiration))
$ExpiredUsers = Get-ADUser -Filter { (PasswordLastSet -lt $emailDate) -and (PasswordLastSet -gt $expiredDate) -and (PasswordNeverExpires -eq $false) -and (Enabled -eq $true) } -Properties DisplayName, PasswordNeverExpires, Manager, PasswordLastSet, Mail, "msDS-UserPasswordExpiryTimeComputed" -SearchBase "$EmployeeOU" | Select-Object DisplayName, samaccountname, manager, PasswordLastSet, @{name = "DaysUntilExpired"; Expression = { $_.PasswordLastSet - $ExpiredDate | Select-Object -ExpandProperty Days } }, @{name = "EmailAddress"; Expression = { $_.mail } }, @{Name = "ExpiryDate"; Expression = { [datetime]::FromFileTime($_."msDS-UserPasswordExpiryTimeComputed") } } | Sort-Object PasswordLastSet
