Stworzyłem aplikacje która (teoretycznie) ma nagrywać a później odtwarzać konkretną akcje. skorzystałem z haków WH_JOURNALRECORD i WH_JOURNALPLAYBACK. Program się kompiluje i faktycznie nagrywa i odtwarza. Ale jak próbuje odtworzyć nagrany ruch myszką to wyskakuje mi po chwili bluescreen. Wie ktoś może jak zaradzić takiemu problemowi? Pracuje na Windowsie 7. Program korzysta z dll stworzonych przeze mnie. O to sam kod:
dll (.cpp)

break;

break;
}

return TRUE;
}

if(delta > 0) return delta;
else return 0;

Przy okazji może ktoś poleciłby książkę taką troche bardziej zaawansowaną do nauki i najlepiej książkę z ćwiczeniami z programowania (najlepiej zawierającą głównie programowanie obiektowe + struktury danych)
