A couple of questions there. Are you running your application on XP? Do you
have Comctl32.dll version 6.0? Do you have a manifest file that specifies
that?
See remarks section of this link
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/shellcc/platform/commctls/listview/messages/lvm_setinsertmark.asp

I am assuming that you are using a CDropTarget class as the base class of
CCustomListCtrl and your OnDragOver actually looks like this

DROPEFFECT OnDragOver(CWnd* pWnd,COleDataObject* pDataObject, DWORD
dwKeyState,CPoint point );

If you are planning on running your application on other platforms older
than XP see this:

Hi,

I was trying to show insertion mark while user draging an item in

CListCtrl,

but I didn't managed. Could you help me what I did wrong?

CCustomListCtrl::OnDragOver( CPoint point )

{

    LVINSERTMARK lv; lv.cbSize = sizeof(lv);

    lv.dwFlags = LVIM_AFTER;

    lv.dwReserved = 0;

     lv.iItem = -1;

     nt nInsertPoint = InsertMarkHitTest( &point, &lv );

     if( lv.iItem != -1 )

        SetInsertMark( &lv );//return error everytime

}

Thanks in advance
