Question

There is a program that creates a log file.

This is an example of the log file it creates:

This program loads this log file into a TStringGrid. The log file is tab delimited. A cell can has a space ” “.

How can I use TStringGrid or an alternative to load such a log file into it like this program?

Thanks!

Answer 1

This procedure loads the log into a string list. For each line in the log, it assigns the CommaText property of the corresponding row in the grid control. That property automatically splits comma- and space-separated tokens in a string. If you have a newer Delphi version, you can use the DelimitedText property instead, which will be more appropriate if the log might ever contain unquoted commas.

procedure LoadLogFile(const FileName: TFileName; Grid: TStringGrid);
var
  LogFile: TStrings;
  i: Integer;
begin
  LogFile := TStringList.Create;
  try
    LogFile.LoadFromFile(FileName);
    Grid.RowCount := LogFile.Count;
    for i := 0 to Pred(LogFile.Count) do
      Grid.Rows[i].CommaText := LogFile[i];
  finally
    LogFile.Free;
  end;
end;
