Delphi-Quellcode:

    if TryStrToFloat( s , w) then
    if w >= 200 then
        begin
         ( sender as TStringGrid).Canvas.Brush.Color := clred;

         ( sender as TStringGrid).Canvas.FillRect(Rect);

         ( sender as TStringGrid).canvas.TextOut(Acol,Arow, ( sender as TStringGrid).cells[Acol,Arow]);

        end;
