CListCtrl LVS_ICON, want to drag an icon to another icon before

But the MSDN display LVS_ICON order is not in order of the index,
This caused me insert drag the icon to release the mouse button icon,

InsertItem (m_nDropIndex, item. The pszText, item iImage); Return was successful, but does not display properly

If is LVS_AUTOARRANGE that there is no change,
If not LVS_AUTOARRANGE mode, this insert images are displayed in the back,

Icon mode is the CListCtrl LVS_ICON how to solve the problem of display after insert sorting? It is not according to the index sorting,

//this function drops an item from a CListCtrl to a CListCtrl 
Void CListCtrlView: : DropItemOnList (CListCtrl * pDropList) 
{
//unhilite the drop target 
PDropList - & gt; SetItemState (m_nDropIndex, 0, LVIS_DROPHILITED); 

Char szLabel [256]. 
LV_ITEM lvi; 

ZeroMemory (& amp; Lvi, sizeof (LV_ITEM)); 
Lvi. IItem=m_nDragIndex; 
Lvi. Mask=LVIF_IMAGE | LVIF_TEXT; 
Lvi. PszText=szLabel; 
Lvi. CchTextMax=255; 
//get the item that was dragged 
VERIFY (m_List. The GetItem (& amp; Lvi)); 

//insert item into CListCtrl 
Lvi. IItem=(m_nDropIndex==1)? PDropList - & gt; GetItemCount () : m_nDropIndex; 
VERIFY (1!=pDropList - & gt; InsertItem (& amp; Lvi)); 
//select the new item we just inserted 
VERIFY (pDropList - & gt; SetItemState (lvi) iItem, LVIS_SELECTED LVIS_SELECTED)); 
//delete the the original item (move operation) 
VERIFY (m_List. Called DeleteItem (m_nDragIndex));
