This line of your code is wrong:
*********
dwStyle|=LVS_EX_FULLROWSELECT| LVS_REPORT|LVS_ICON ;
*********
LVS_EX_FULLROWSELECT is the eXtended style and you may not no mix it with
"usual" styles. It only may be set with CListCtrl::SetExtendedStyle
method.

No, if you looked at commctrl.h file you would see:
********
#define LVS_SORTDESCENDING 0x0020
.....
#define LVS_EX_FULLROWSELECT 0x00000020 // applies to report mode only
********
So, you just set LVS_SORTDESCENDING style again after you tried to remove
it! :))

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
