Pred kakšnim tednom sem na faksu uspešno zagovoril preprosto seminarsko nalogo Budilka (Alarm clock). Ker bo kakšna funkcija komu koristila bom program objavil tudi tukaj na blogu.

Vse skupaj sem zapakiral še v zanimivo grafično podobo, tako da je v kakšnem pogledu lahko tudi uporaben program.

Samo uporabnost programa lahko stestirate tukaj.

To je sama koda, če bi pa kdo želel še sam program za Visual Studio 2008:
