  Вопрос: Проблема Win2K Добавлено: 03.04.03 14:57  

Автор вопроса:  Sernij

Этот пример я нашёл тут на вашем сайте, всё отлично работает под Win98/Me, а мне к сожалению нужно выключить комп в Win2k/WinXP как бы это сделать и что нужно переделать или легче написать новый код??

Пример : под Win98/Me Выглядит так:

'КОД ФОРМЫ

Private Sub mnuCompOff_Click()
Call ShutDown(EWX_SHUTDOWN)
End Sub

Private Sub mnuCompReboot_Click()
Call ShutDown(EWX_REBOOT)
End Sub

Потом вызываешь нужную тебе процедуру

Padre ты бы не мог прокомментировать свой ответ и вооще пояснить в чём фишка отличий программирования для Win2K/NT/XP .Плыыз. Это для того чтобы и я мог делать это сам а не попрошайничать тут. Заранее спасибо

Фишка в том, что при выключении компьютера под ХР надо иметь на это необходимую привелегию, которая по умолчанию выключена даже у администратора, и вся эта дополнительная галиматья в коде как раз и призвана для получения твоей программой необходимой привелегии.
