Powershell DISM Progression bar - powershell

Question

I have a problem, I am building a powershell script to restore / save wim images using the DISM command.
So I use a winform interface, with a progress bar.
However, I can't find a way to send the% information for my progress bar.
Currently I have done tests with my DISM command in fact for example >> c: \ test and I manage to recover the% but I cannot do them simultaneously.
Here is the code, do you have any idea?
Foreach ( $line in "c:\test.txt" )
{
$content = Get-Content -Path 'c:\test.txt'
$content
$count = ($content | Select-String -Pattern '%' -AllMatches)
$PCcomplete = $count.Count-1
}
Dism /Capture-Image /ImageFile:$chemin /CaptureDir:$choixlettre\ /Name:$nom /Compress:max /LogLevel:4 >> c:\test.txt

Answer 1

Finally, it's work ! But my progression bar stop at 96...97 the count forget some number..
$sb = [scriptblock]::Create("dism /apply-image /imagefile:$chemin /index:1 /applydir:t: /LogLevel:4 >>t:\test.txt")
$job = Start-Job -ScriptBlock $sb
#
$pccomplete = 0
$pccomplete1 = 0
# Boucle
while((Get-Job | Where-Object {$_.State -ne "Completed"}).Count -gt 0)
{
$content = get-content -Path 't:\test.txt'
$count = ($content | Select-String -Pattern '%' -AllMatches)
$PCcomplete = $count.Count
start-sleep -Second 2
if( $pccomplete1 -ne $pccomplete )
{
$pccomplete1 = $pccomplete
$richtextBox_history.AppendText("$PCcomplete`n")
$progressBar1.Value = $pccomplete
}
