memo1.Lines.EndUpdate;
Application.Processmessages;
What you did makes no sense whatsoever. The whole point of
beginupdate/endupdate is to mark a list of changes, and to prevent the
UI from updating while you do the changes.
The use of Add() is easier to understand.
Michael.
But this way you wouldn't see the progress.
Including only
Memo1.Lines[Memo1.Lines.Count-1] := '#### LAST LINE
---'+IntToStr(i)+'-----------------------------------------------------------';
will also include all calculations of TMemo so you prevent flickering
and see the progress. This makes sense to me.
Your solution of course is mutch faster but I thought seeing the
progress is important for Jürgen.
