c# - debugging contacts deletionStvar je sledeća:
Imam listview ispunjen kontaktima koji se čuvaju u XML file-u. Uzmimo za primer da tamo imam 5 ljudi. Ako pokušam da izbrišem svih 5 - nakon ponovnog startovanja programa - svih 5 će ponovo biti tamo, dakle, kao da ih nisam ni brisao. Moguće je od tih 5 obrisati samo 4 (ako ih imam 100, moguće je obrisati 99) - jedan će uvek ostati. Desi se i da nakon brisanja nekog kontakta, kada pokušam sledeći - ne uspevam ni da ga izbrišem, dakle pokušam da ga selektujem i javi se sledeći error:
Ključne stvari ovde su:
