Перехват вывода консольного окна, запущенного другой программой - VB

Формулировка задачи:

Привет всем барсикам и заглянувшим в тему ! Есть программа, которая создает консольное окно, выполняет в нем команды и сразу закрывает это окно. Как прочитать весь текст из такого окна. Допустим, я отслежу таймером изменение хендла по GetForegroundWindow, найдя окно консоли. А как дальше? Чем считать текст? Структура STARTUPINFO еще имеет влияние на поведение процесса, если внести в нее модификации уже после запуска процесса?
