Question

我在while（$ true）循环内运行选择日期日历功能。因此，它不断运行。

但是，如果用户单击表单上的退出按钮（不在对话框中），我想杀死它。我该怎么办？

Query:["DELETE FROM old_post WHERE id = ?"], Params:[(1)]
Query:["delete from post where id=? and version=?"], Params:[(1, 1)]

Answer 1

您不需要

 while($true) {}

只要写

[void][System.Reflection.Assembly]::LoadWithPartialName("System.windows.forms")
Function Pick-Date {
  $Cal = New-Object System.Windows.Forms.MonthCalendar
  $Cal.ShowWeekNumbers = $true
  $Cal.MaxSelectionCount = 1
  $Cal.Dock = 'Fill'
  $Form = New-Object Windows.Forms.Form
  $Form.text = "Colocar fecha que desea enviar. Y presiona Enter"
  $Form.Size = New-Object Drawing.Size @(656,620)
  $btnSelect = New-Object System.Windows.Forms.Button
  $btnSelect.Size = "100,100"
  $btnSelect.add_Click({ $Form.close() })
  $btnSelect.Location = New-Object System.Drawing.Point(530,480)
  $btnSelect.Text="ENTER"
  $Form.Controls.Add($btnSelect )
  $Form.AcceptButton = $btnSelect
  $Form.Controls.Add($Cal)
  $Form.Add_Shown({$Form.Activate()})
  [void]$Form.ShowDialog()
  return (Get-Date($Cal.SelectionStart))
}

$fecha = Pick-Date
write-host $fecha

除非您希望即使用户输入了单击日期也打开日历表单？当用户单击退出或输入日期时，以上版本将关闭。

您可以在FormClosing事件中检查关闭表单的原因，并设置脚本范围的变量以防止重新打开：

如果我单击表单上的退出按钮，是否退出脚本？
