Text parameter not working with Powershell Progress Bar

I've been looking around for the past half hour on how to show the text inside of a GUI ProgressBar in Powershell, and everything I've tried has failed. I've even been referencing MSoft docs on it.
Am I doing something wrong? How do I add in the text?
This isn't my full script or exactly how I'll be using it - I just made an example so I could try to get it working.
Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName System.Drawing
$form = New-Object System.Windows.Forms.Form
$form.Size = '500,300'
$form.StartPosition = 'CenterScreen'
$form.Topmost = $true
$computerList = 'server01', 'server02', 'server03', 'server04', 'server05', 'server06', 'server07', 'server08', 'server09', 'server10'
$progressbar1 = New-Object System.Windows.Forms.ProgressBar
$progressbar1.Size = '300, 20'
$progressbar1.Location = '20,60'
$progressbar1.Text = "Processing..."
$progressbar1.Maximum = $computerList.Count
$progressbar1.Step = 1
$progressbar1.Value = 0
foreach ($computer in $computerList){
$progressbar1.PerformStep()
}
$form.Controls.Add($progressbar1)
$form.ShowDialog()
I guess the easiest way is to have a Label control above the progressbar and update the text in there:
$progressLabel = New-Object System.Windows.Forms.Label
$progressLabel.Size = '300, 20'
$progressLabel.Location = '20,40'
$progressLabel.Text = "Processing..."
$form.Controls.Add($progressLabel)
foreach ($computer in $computerList){
$progressLabel.Text = "Doing stuff on computer '$computer'.."
$progressbar1.PerformStep()
# perform your action on $computer here
}

PowerShell Add_Click in foreach loop

What I am trying to accomplish is to create buttons that launch exe files in a certain directory when clicked, but when I try using a foreach loop to create a few buttons, all of the buttons just launch the file the last button is supposed to launch.
Add-Type -AssemblyName System.Windows.Forms
Add-Type -AssemblyName System.Drawing
$form = New-Object System.Windows.Forms.Form
$form.Text = 'Main Window'
$form.Size = New-Object System.Drawing.Size(600,400)
$flp = New-Object System.Windows.Forms.FlowLayoutPanel
$flp.Location = New-Object System.Drawing.Point(0,0)
$flp.Height = $form.Height
$flp.Width = $form.Width
$form.Controls.Add($flp)
$files = Get-ChildItem "$home\Downloads" -Include *.exe -Name
foreach ($file in $files){
$button = New-Object System.Windows.Forms.Button
$flp.Controls.Add($button)
$button.Width = 100
$button.Height = 50
$button.Text = $file
$button.Add_Click{
Start-Process -FilePath "$home\Downloads\$file"
}
}
$form.Topmost = $true
$form.ShowDialog()
Whatever I'm doing is probably pretty stupid, so I was just looking for any alternatives or solutions to this other than to just hard code everything.
It is likely that you need to use .GetNewClosure() ScriptBlock method so that each script block (button click event) holds the current value of the $file variable at the moment of enumeration.
Example of what this means:
$blocks = foreach($i in 0..5) {
{ "hello $i" }
}
& $blocks[0] # => hello 5
& $blocks[1] # => hello 5
$blocks = foreach($i in 0..5) {
{ "hello $i" }.GetNewClosure()
}
& $blocks[0] # => hello 0
& $blocks[1] # => hello 1
In that sense, and assuming this is the issue, the following should work:
foreach ($file in $files) {
$button = New-Object System.Windows.Forms.Button
$button.Width = 100
$button.Height = 50
$button.Text = $file
$thisEvent = {
Start-Process -FilePath "$home\Downloads\$file"
}.GetNewClosure()
$button.Add_Click($thisEvent)
$flp.Controls.Add($button)
}
A nice alternative to having a need to use .GetNewClosure() can be seen on this answer. The .Tag property of the Button can be used to store the information of the file's path which then can be used on the button's .Click event:
foreach ($file in $files) {
$button = New-Object System.Windows.Forms.Button
$button.Width = 100
$button.Height = 50
$button.Text = $file
# Store the file's path in the Tag's property of this Button
$button.Tag = "$home\Downloads\$file"
$button.Add_Click({
Start-Process -FilePath $this.Tag
})
$flp.Controls.Add($button)
}

Anyone can give me idea please. Really appreciate for your help. Thank you.
Can you try like this? Put your background operation in place of Start-Sleep -s 2 and the gif file still show moving.
$Form = New-Object system.Windows.Forms.Form
$Form.Location= New-Object System.Drawing.Size(100,100)

Using PowerShell For Developing A Notification For An RSS News Alert

I have this basic code that works fine for simple text message alert. Now, it would be handy to connect this script to alert the user whenever there is a new RSS feed from our ITS alert system.
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
$objNotifyIcon = New-Object System.Windows.Forms.NotifyIcon
$objNotifyIcon.Icon = [System.Drawing.SystemIcons]::Information
$objNotifyIcon.BalloonTipIcon = "Info"
$text = 'This is just a text'
$objNotifyIcon.BalloonTipText = $text
$objNotifyIcon.BalloonTipTitle = "Tip Title"
$objNotifyIcon.Visible = $True
$objNotifyIcon.ShowBalloonTip(30000)
Here is an idea for auto-close:
Function Get-BalloonTip {
[CmdletBinding()]
Param (
[Parameter(Mandatory=$true)]$Text,
[Parameter(Mandatory=$true)]$Title,
$Icon = 'Info',
$Timeout = $10000
)
Process {
Add-Type -AssemblyName System.Windows.Forms
If ($PopUp -eq $null) {
$PopUp = New-Object System.Windows.Forms.NotifyIcon
}
$Path = Get-Process -Id $PID | Select-Object -ExpandProperty Path
$PopUp.Icon = [System.Drawing.Icon]::ExtractAssociatedIcon($Path)
$PopUp.BalloonTipIcon = $Icon
$PopUp.BalloonTipText = $Text
$PopUp.BalloonTipTitle = $Title
$PopUp.Visible = $true
$PopUp.ShowBalloonTip($Timeout)
Start-Sleep 5
$PopUp.Visible = $false
} # End of Process
} # End of Function
Get-BalloonTip -Text "Hello" "Check This out"

Don’t display Cancel in PowerShell script result

I have the following PowerShell script which displays file dialog to select a txt file. If user cancels dialog then provide a multiline text box
function GetDetails() {
Add-Type -AssemblyName System.Windows.Forms;
$browser = New-Object System.Windows.Forms.OpenFileDialog;
$browser.Filter = "txt (*.txt)|*.txt";
$browser.InitialDirectory = "E:\";
$browser.Title = "select txt file";
$browserResult = $browser.ShowDialog();
if($browserResult -eq [System.Windows.Forms.DialogResult]::OK) {
$nfoFile = $browser.FileName;
if([string]::IsNullOrWhiteSpace($txtFile)) {
return GetFromForm;
}
$txtFile = [System.IO.Path]::ChangeExtension($nfoFile, ".dac");
$txtFile = $temp + [System.IO.Path]::GetFileName($txtFile);
$exeArgs = "-f -S `"$txtFile`" -O `"$txtFile`"";
Start-Process $anExe -ArgumentList $exeArgs -Wait;
$result = Get-Content $txtFile | Out-String;
$browser.Dispose();
return $result;
} else {
return GetFromForm;
}
}
function GetFromForm(){
Add-Type -AssemblyName System.Windows.Forms;
$form = New-Object System.Windows.Forms.Form;
$form.Width = 800;
$form.Height = 600;
$txtBox = New-Object System.Windows.Forms.TextBox;
$txtBox.Multiline = $true;
$txtBox.AcceptsReturn = $true;
$txtBox.AcceptsTab = $true;
$txtBox.Visible = $true;
$txtBox.Name = "txtName";
$txtBox.Width = 760;
$txtBox.Height = 660;
$form.Controls.Add($txtBox);
$form.ShowDialog();
 
$form.Dispose();
return $txtBox.Text;
}
$desc = GetDetails;
cls;
Write-Host $desc;
Here I have two issues:
In Write-Host $desc, prints also Cancel hereiswhateverstrimg string if user chose to cancel dialog. How to avoid that?
If I run script in ISE, the generated form (in second function) will be always behind ISE even I call ShowDialog(), I expected to behave as modal dialog. It’s normal or there is a fix for this ?
Ok, there are a few changes that I made for efficiency and a few for functionality. Read the comments in the script for the explanations.
# Just add types once. There is no need to add the types in each function.
Add-Type -AssemblyName System.Windows.Forms;
Add-Type -AssemblyName System.Drawing
function GetDetails() {
$browser = New-Object System.Windows.Forms.OpenFileDialog;
$browser.Filter = "txt (*.txt)|*.txt";
$browser.InitialDirectory = "E:\";
$browser.Title = "select txt file";
$browserResult = $browser.ShowDialog();
# Combined the if statements
if($browserResult -eq [System.Windows.Forms.DialogResult]::OK -and [string]::IsNullOrWhiteSpace($txtFile) -ne $true) {
$nfoFile = $browser.FileName;
$txtFile = [System.IO.Path]::ChangeExtension($nfoFile, ".dac");
$txtFile = $temp + [System.IO.Path]::GetFileName($txtFile);
$exeArgs = "-f -S `"$txtFile`" -O `"$txtFile`"";
Start-Process $anExe -ArgumentList $exeArgs -Wait;
# The Raw flag should return a string
$result = Get-Content $txtFile -Raw;
$browser.Dispose();
return $result;
}
# No need for else since the if statement returns
return GetFromForm;
}
function GetFromForm(){
$form = New-Object System.Windows.Forms.Form;
$form.Text = 'Adding Arguments'
$form.Size = New-Object System.Drawing.Size(816,600)
$form.StartPosition = 'CenterScreen'
# Added a button
$OKButton = New-Object System.Windows.Forms.Button
$OKButton.Location = New-Object System.Drawing.Point(585,523)
$OKButton.Size = New-Object System.Drawing.Size(75,23)
$OKButton.Text = 'OK'
$OKButton.DialogResult = [System.Windows.Forms.DialogResult]::OK
$form.AcceptButton = $OKButton
$form.Controls.Add($OKButton)
$txtBox = New-Object System.Windows.Forms.TextBox;
$txtBox.Multiline = $true;
$txtBox.AcceptsReturn = $true;
$txtBox.AcceptsTab = $true;
$txtBox.Visible = $true;
$txtBox.Name = "txtName";
$txtBox.Size = New-Object System.Drawing.Size(660,500)
$form.Controls.Add($txtBox);
# Needed to force it to show on top
$form.TopMost = $true
# Select the textbox and activate the form to make it show with focus
$form.Add_Shown({$txtBox.Select(), $form.Activate()})
# Finally show the form and assign the ShowDialog method to a variable (this keeps it from printing out Cancel)
$result = $form.ShowDialog();
# If the user hit the OK button return the text in the textbox
if ($result -eq [System.Windows.Forms.DialogResult]::OK)
{
return $txtBox.Text
}
}
$desc = GetDetails;
cls;
Write-Host $desc;
You can see reference material here: https://learn.microsoft.com/en-us/powershell/scripting/samples/creating-a-custom-input-box?view=powershell-6
You need to suppress output of $form.ShowDialog() in GetFromForm:
$form.ShowDialog()|out-null
Powershell will add to a return value everything that was outputted to host within a function/commandlet.
Regarding your second issue - see this answer
And please do not use semi-colon at an end of line. This is not C# and will confuse you into thinking that the line is ended here but it's not quite true.
