$datePickerLabel.Text = “date”
$datePickerLabel.Location = “15, 10”
$datePickerLabel.Height = 22
$datePickerLabel.Width = 90
$mainForm.Controls.Add($datePickerLabel)
# MinTimePicker Label

$datePicker.Width = “150”
$datePicker.Format = [windows.forms.datetimepickerFormat]::custom
$datePicker.CustomFormat = “dd/MM/yyyy”
$mainForm.Controls.Add($datePicker)
# MinTimePicker
$minTimePicker = New-Object System.Windows.Forms.DateTimePicker
$minTimePicker.Location = “110, 42”
$minTimePicker.Width = “150”
