Question

       foreach (KeyValuePair<int, int[]> item in replay)// count should be more than 2
        {           
            makeSelfMoves = replay[item.Key];
            codeFile.ExecuteAll(makeSelfMoves[0], makeSelfMoves[1], makeSelfMoves[2], makeSelfMoves[3]);
            PrintPieces(codeFile.PieceState());
            // MessageBox.Show("rowStart: " + makeSelfMoves[0] + ". rowEnd: " + makeSelfMoves[2] + ". columnStart: " + makeSelfMoves[1] + ". columnEnd: " + makeSelfMoves[3] + "____a is: " + a);

        }

i want to execute this whole iteration, that i responsible for a game replay, in 1 second intervals. i put a timer in my form and set it to 1 second (this should make the pieces to be moved at 1 second intervals). i made an event, and before the loop i put the statement, timer1.enabled=true. The iteration will reach the end in a quick manner.. how do you use a timer to set iteration to execute each second using the timer?

  public void ReplayGame()
    {
        Class2.replayIsOn = true;
        replay=serializeMeh.giveBackDictionary();
        int[] makeSelfMoves=new int[4];


        //Timer t = new Timer();
        //t.Interval = 1000;
        //t.Tick += timer1_Tick;
        //t.Enabled = true;
        //t.Start();
        if (backgroundWorker1.IsBusy != true)
        {
            // Start the asynchronous operation.
            backgroundWorker1.RunWorkerAsync();
        }

        //foreach (KeyValuePair<int, int[]> item in replay)// count should be more than 2
        //{


        //    makeSelfMoves = replay[item.Key];
        //    codeFile.ExecuteAll(makeSelfMoves[0], makeSelfMoves[1], makeSelfMoves[2], makeSelfMoves[3]);
        //    PrintPieces(codeFile.PieceState());


        //    MessageBox.Show("rowStart: " + makeSelfMoves[0] + ". rowEnd: " + makeSelfMoves[2] + ". columnStart: " + makeSelfMoves[1] + ". columnEnd: " + makeSelfMoves[3] );

        //}


    }

The above method is activated if i want a replay.

        private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
    {
        BackgroundWorker worker = sender as BackgroundWorker;

        int[] makeSelfMoves = new int[4];

        foreach (KeyValuePair<int, int[]> item in replay)// count should be more than 2
        {
            makeSelfMoves = replay[item.Key];// delivers an array of a single move location startrow,startcolumn,endrow,endcolun
            codeFile.ExecuteAll(makeSelfMoves[0], makeSelfMoves[1], makeSelfMoves[2], makeSelfMoves[3]);
            PrintPieces(codeFile.PieceState());// prints the code on the board

            System.Threading.Thread.Sleep(1000);
        }

    }

it does the work, but the problem that i had is after the loop finishes, the pieces that existed disappear. is it because of the background worker, cause without it , i have no pieces disappear at the end of the process. The second time that i activate the method, it happens

Run it in a background thread and put Thread.Sleep(1000) in the loop.

This way it will be time based and not freeze your app.
