PowerShell - Add text to ProgressBar (GUI)

I'm trying to put a text on a progress bar (percentage, etc) but it's not working. Progress bar text is based on this. Below is a simplified version of the code.

#Form
[void][System.Reflection.Assembly]::LoadWithPartialName("System.Drawing")
[void][System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
$Form = New-Object System.Windows.Forms.Form
$Form.Size = New-Object System.Drawing.Size (604,430)
$Form.Text = "Move User Files"
$Form.StartPosition = "CenterScreen"
$Form.MinimizeBox = $False
$Form.MaximizeBox = $False
$Form.WindowState = "Normal"
$Form.SizeGripStyle = "Hide"

#progres bar
$progressBar = New-Object System.Windows.Forms.ProgressBar
$progressBar.Name = 'ProgressBar'
$progressBar.Value = 0
$progressBar.Style = "Continuous"
$progressBar.Location = New-Object System.Drawing.Size (4,357)
$progressBar.Size = New-Object System.Drawing.Size (580,30)
$Form.Controls.Add($progressBar)

#This is the part that is not working
$gr = $progressBar.CreateGraphics()
$progressBarText = '0%'
$Font = new-object System.Drawing.Font("Bauhaus 93", 30, "Bold", "Pixel")
$Brush = New-Object Drawing.SolidBrush([System.Drawing.Color]::Black)
$PointF = [System.Drawing.PointF]::new($progressBar.Width /2 - ($gr.MeasureString($progressBarText,$Font).Width / 2),
    $progressBar.Height /2 - ($gr.MeasureString($progressBarText,$Font).Height / 2))
$gr.DrawString($progressBarText, $Font, $Brush, $PointF)

#Show The Form
$Form.Add_Shown({ $Form.Activate() })
[void]$Form.ShowDialog()

I Don't receive any error, but it simply doesn't show the text. What am I missing? any thoughts?

How I did it and it worked.

I put it at the beginning of my script like this:

$Font = New-Object System.Drawing.Font('Arial', 10, 'Bold', 'Pixel')
$brush1 = New-Object Drawing.SolidBrush([System.Drawing.Color]::Black)
$PBCG = $ProgressBar1.CreateGraphics()

I did a function that writes, like this:

function UpdateText([String] $text){
    $x = ($ProgressBar1.Width / 2) - ([int]$PBCG.MeasureString($text, $Font).Width / 2)
    $y = ($ProgressBar1.Height / 2) - ([int]$PBCG.MeasureString($text, $Font).Height / 2)
    $PointF = [System.Drawing.PointF]::new($x, $y)
    $PBCG.DrawString($text, $Font, $brush1, $PointF)
}

I hope it helped you

is there some reason the one in PowerShell won't work for you? Here's a snippet from a real script that I use multiple times per day. You might be able to tweak it to your needs. I realize it's not a GUI but it is 100% PowerShell.

       try {
           "Your Secret" | clip
            1..$Delay | % {
                if (-not ( [console]::KeyAvailable) ) {
                    write-host "$($_)`r" -NoNewline
                    Write-Progress -Status "Press Any Key to continue" `
                        -Activity "Paste password before it is removed from the clipboard" `
                        -PercentComplete ($_ * 100 / $Delay)
                    Start-Sleep -Seconds 1
                }
            }
        } finally {
            $null | clip

            if ([console]::KeyAvailable) {
                $x = [console]::ReadKey()
                Write-Information -MessageData $x -Tags "KeyStroke"
            }
        }

(How you really get a secure password into the clipboard is a separate task left to the reader.)

Shouldn't you be setting the text property on the progressbar

$progressBarText should be $progressBar.Text
