Does anybody know how to remove whitespace from a memo?

Blank lines being whitespace
and also any blank spaces like this "the cat                              sat on the mat, have                   a nice day"

Thanks

There is a lot to go through in that link, so I put together a function for you to do what you asked for:

procedure StripWhiteSpaces(AMemo: TMemo);
var p1,p2: pchar;
    s: string;
    i: integer;
begin
  s:= AMemo.Lines.Text;
  if s = '' then exit;

  p1:= pchar(s);
  p2:= p1;
  while p2^ <> #0 do
  begin
    if (p2^ = ' ') AND ((pchar(p2+1)^ = ' ') or (pchar(p2-1)^ in [#13,#10]))
      then Delete(s, p2 - p1 + 1,1)
      else inc(p2);
  end;
  AMemo.Lines.Text:= trim(s);
  for i:= AMemo.Lines.Count-1 downto 0 do
    if AMemo.Lines[i] = ''
      then AMemo.Lines.Delete(i);
end;

Regards

that will teach me to choose a function and not just give a link to the list of functions. though it should have been more correct to at least mark my resonse as assisted.
whatever.
