How can I write a simple HH:MM:SS counter to time a procedures duration ?. The counter does not have to be very accurate just a start/stop counter to the nearest second or so. I would like a coded answer without using any components.

Thanks
Paul.

procedure ProcedureName;
var
  TotalTime, StartTime: Cardinal;
begin
  StartTime := GetTickCount;
  // Here your code
  TotalTime := GetTickCount - StartTime;
  ShowMessage('It took ' + IntToStr(TotalTime) + ' msec.');
end;

DeNavigator,
 Sorry, maybe my question was not very clear. I was hoping for say a TLabel caption to update in real time as the procedure executed e.g. '00:00:01' - '00:00:02'... etc.

Thanks
Paul.

Drag a TLabel and a TTimer onto your form. Then the following code will update the label with the time.

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, ExtCtrls, StdCtrls;

type
  TForm1 = class(TForm)
    Label1: TLabel;
    Timer1: TTimer;
    procedure Timer1Timer(Sender: TObject);
  private
    { Private declarations }
  public
            { Public declarations }
            Clock : integer;
      end;

var
      Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Timer1Timer(Sender: TObject);
begin
      Inc(Clock);
      Label1.Caption := Format('%2.2d:%2.2d:%2.2d', [(Clock div 3600) mod 24, (Clock div 60) mod 60, Clock mod 60]);
end;

end.

PS - if you are doing a processor-intensive procedure, you may want to call Application.ProcessMessages every now and again (at *least* once per second) to allow the timer to trigger.
