I'm working on a simple program. It will compile,but whenever I press the delete button a message pops up and says it needs to close. I looked at the error details and It's error code was 0xc0000005.
This is where I think the problem is:
for(i= 0; i < NumOfItems; i++)
{
ListView_GetItemText(hWndListView, i, 0, text, 256);
ListView_GetItemText(hWndListView, i, 1, text2, 256);
string s = text;
ListViewText[i][0] = s;
string s2 = text2;
ListViewText[i][1] = s2;
}This is the whole code. I'm sorry for posting all of it, but the problem might be somewhere else.
