Zadatak je da napravim "MFC aplikaciju" u koju unosim ime prezime i broj indeksa,program to upisuje u txt fajl a imam i taster i za citanje pa mogu da citam podatke iz tog txt fajla.Vecinu stvari sam rjesio ali sam zapeo kod iscitavanja podataka iz fajla, uspjevam da iscitam samo prvi red iz fajla. Treba mi da mogu zasebno da iscitavam svaki red u polje ispis.Bilo bi super i ako bi mogao da radim pretrazivanje na osnovu broja indeksa, tj. pretragu na osnovu jednog djela stringa. Unapred hvala.
