Как узнать, когда завершилось запущенное
приложение
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.

Exit Function
End If
RunAndWait =

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