Как узнать, когда завершилось запущенное приложение

Askhat Urazbaev

В статье о скрытом форматировании дискеты я предложил один способ ждать, пока запущенное приложение завершится. Вот какой прием прислал Askhat Urazbaev.

Пример не адаптирован, но его легко исправить.

Как узнать, когда завершилось запущенное приложение?

Использование:
If RunAndWait("smth.exe", "c:\windows", vbNormalFocus) Then
    MsgBox "Registry backuped!"
