textfile open -> blockwise

[dx111ge]

Hello,

normally a textfile will be opened line by line , with a large textfile, this takes a long time. I saw some tools, which are faster (1 sec compared to 3-5 min). Maybe this is more a block reading ? I don't know , but thanks for ponting me in the right direction !

Thanks
Sven

Hi,

If you want to read the contents of an entire file you would be better off using a TFileStream.

e.g.

var
  StrBuff: string;
  fsInput: TFileStream;
begin
  fsInput := TFileStream.Create(aFileName, fmOpenRead or fmShareExclusive);
  try
    SetLength(StrBuff, fsInput.Size);
    fsInput.Read(StrBuff[1], fsInput.Size);
  finally
    fsInput.Free;
  end;
end;

The contents of the file will then be held in StrBuff
