Timer (Amateuerfrage)

[Klaus01]

Delphi-Quellcode:

procedure Delay(Milliseconds: Integer);
var
  Tick: DWord;
  Event: THandle;
begin
  Event := CreateEvent(nil, False, False, nil);
  try
    Tick := GetTickCount + DWord(Milliseconds);
    while (Milliseconds > 0) and
          (MsgWaitForMultipleObjects(1, Event, False, Milliseconds, QS_ALLINPUT) <> WAIT_TIMEOUT) do
    begin
      Application.ProcessMessages;
      if Application.Terminated then Exit;
      Milliseconds := Tick - GetTickcount;
    end;
  finally
    CloseHandle(Event);
  end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
        max:=100;
        i:=1;
        ProgressBar1.Max:=max;
        while i < max do
        begin
                IdIcmpClient1.Host := Form1.Edit1.Text;
                IdIcmpClient1.Ping();
                If IdIcmpClient1.ReplyStatus.BytesReceived > 0 Then

                ListBox1.Items.Add(IntToStr(i) + ' ' + IdIcmpClient1.Host+' erreichbar '+ IntToStr(IdIcmpClient1.ReplyStatus.BytesReceived))
                else
                ListBox1.Items.Add(IntToStr(i) + ' ' + IdIcmpClient1.Host+' nicht erreichbar');

                i:=i+1;
                delay(StrToInt(Edit2.Text));  // <----
                ProgressBar1.Position:=i;
        end;

end;

procedure TForm1.Timer1Timer(Sender: TObject);
begin
        Timer1.Enabled:=False;
        Form1.Refresh;
        Application.ProcessMessages;
        Timer1.Enabled:=True;
end;
