why memo.loadFromFile takes so long time?

Question

I use TMemo to display long strings. I was very surprised that method : Memo1.loadfromfile('mem.txt') [mem.txt = 111 kB] took about 35 seconds, what is really really long time.

How can I make TMemo load strings in real time?

thanx

Answer 1

Because WordWrap property was true...

Answer 2

:-) And you can try

try
  Memo1.Lines.BeginUpdate;
  Memo1.LoadFromFile('mem.txt');
finally
  Memo1.Lines.EndUpdate;
end;

Answer 3

You did not say which version of Delphi you are using. In Delphi 2009 and later, TStrings is now Unicode aware, and thus has to perform additional processing when non-Unicode (Ansi/UTF) encoded files are being loaded.
