Hi all,

I have a listbox with a list of items.

Some lines in the listbox have the word "NULL"

I need to get rid of any of this but I don't want to take it off and leave a blank line.

I need to search all items with "NULL" and Take them off but NOT leave a blank line either.

Is this possible please?

Thanks

var i: integer;
begin
 for i := ListBox1.Items.Count - 1 downto 0 do
  if ListBox1.Items[i] = 'NULL' then
   ListBox1.Delete(i);
end;
