Also, I would try using a different index to insert. For example, if iPos
is 1 and you insert at one it will return 1 then if you do it again it
should push the other '1' down. That should be easy to check in the
debugger. Also, why are you make the image index by -1?

Hi,
I have a SDI application in which one of the panes is CListView derived.
The list view is in report mode
I am inserting the items in the list but some items doesn't get inserted
in the position I am inserting.

I have over-ridden the create member of the CListView like this

BOOL CMyListView::Create(LPCTSTR lpszClassName, LPCTSTR lpszWindowName,
DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID,
CCreateContext* pContext)
{
dwStyle ^=LVS_SORTASCENDING;
dwStyle ^=LVS_SORTDESCENDING ;
dwStyle|=LVS_EX_FULLROWSELECT| LVS_REPORT|LVS_ICON ;

return CWnd::Create(lpszClassName, lpszWindowName, dwStyle, rect,
pParentWnd, nID, pContext);
}

and I am inserting the items like

LVITEM item;
memset(&item,0,sizeof(item));
item.mask = LVIF_TEXT |LVIF_PARAM | LVIF_IMAGE;
item.iItem = iPos;
item.iImage = -1;
item.lParam = lTAG;
item.pszText = (LPTSTR)szItemText;

int nPos = GetListCtrl().InsertItem(&item);

the value of iPos starts at 0 and increments for subsequent items and then
inserting the subitems using SetItemText. I have also tried passing 0 for
item.iItem for all items. In either case the items should be inserted
either at top or end of the list, but some items goes and anywhere.

What could be the reason for the item not getting inserted at the
requested index?

Thanks & Regards
Ashutosh
