Hello all,

Thanks Jonas your dynamic listview is faster but not as fast as I'd care to have
it be.

"Dont get me wrong Jonas method is really fast,  I just have several thousand
records to list"

Could someone check this code to make it faster..

sequence data, subdata
integer item, subitem
atom LVITEM, VOID

for ix = length(data) to 1 by -1 do
     item += 1
     subitem = 0
          for xi = 1 to length(data[ix]) do
               subdata = data[ix][xi]
               subitem += 1
               LV_ITEM = struct_LVITEM(lvitem_MASK, item-1, subitem-1, 0, 0,
subdata, 0, 0)
                    if subitem = 1 then
                        VOID = sendMessage( LV_id, LVM_INSERTITEM, 0, LV_ITEM )
                    else
                        VOID = sendMessage( LV_id, LVM_SETITEMTEXT, item-1,
LV_ITEM )
                    end if
                    release_mem(LV_ITEM)
          end for

         -- FASTER THAN >
         -- lParams[ix] = addLVItem( LV_id, 0, data[ix])
 end for

My guess is (and I'll keep working on it) that I'll need to get away from the
win32libs mem functions
and poke in each subdata myself only to achieve nominal speed increase..

Any Suggestions?
