var TextBuf   : PChar;
    Index,
    WordCount : Integer;
begin
  Memo1.SelectAll;
  GetMem(TextBuf, Memo1.SelLength + 2);
  try
    Memo1.GetSelTextBuf(TextBuf, Memo1.SelLength);
    TextBuf[Memo1.SelLength+ 1] := #0;
    TextBuf[Memo1.SelLength] := #32;
    Index := 0;
    WordCount := 0;
    while Index < StrLen(TextBuf) do
     begin
       if (Buffer[Index] = #32) and (Buffer[Index + 1] <> #32)
        then Inc(WordCount);
       Inc(Index);
     end;
  finally
    FreeMem(TextBuf, Memo1.SelLength + 2);
  end;
end;

Hi amigo,
   I've tried the code, but it gives me an unknown identifier at Buffer[index]. Any ideas?
Cheers.

oops, a little typo. replace the line
if (Buffer[Index] = #32) and (Buffer[Index + 1] <> #32)
with
if (TextBuf[Index] = #32) and (TextBuf[Index + 1] <> #32)

Hi again,

    Maybe I'm being thick, but how do I output the result in a messagebox? I've tried doing an IntToStr(WordCount), but the MessageBox command gives me a type mismatch. How do I output the result?
Points upa bit.
Cheers.

Application.MessageBox uses PChar strings. Declare a buffer string and typecast. e.g.
var MsgStr : string
begin
  MsgStr := Format('I have found %s words in this text', [WordCount]);
  Application.MessageBox(PChar(MsgStr), 'Note', mb_ok);
end;
