}
else {
Write-Host "close"
}
No big problem, just place the switch condition directly inside the OK Button-Click Event and do "not" set AcceptButton Property (which would normaly close the form automatically), then the form remains open until you either close the form by the x or the cancel button.
Finally please mark the thread as "solved", thanks.
