I'm trying to send a random PictureBox to the timer1_tick but I'm having a problem with it...

This is my code by now.

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

using System.Threading;

using System.IO;

using System.Drawing.Imaging;

using System.Drawing.Drawing2D;

using System.Collections;

using System.Globalization;

using System.Resources;

namespace Move_the_Block_Project

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

PictureBox Arrow_S;

int n;

List Arrows = new List(3);

Arrows.Add(A_Up);

Arrows.Add(A_Right);

Arrows.Add(A_Left);

Arrows.Add(A_Down);

n = SelectRandom();

Arrow_S = Arrows[n];

timer1.Interval = 10;

}

public int SelectRandom()

{

Random random = new Random();

int a = random.Next(0, 3);

return a;

}

private void timer1_Tick(object sender, EventArgs e)

{

Arrow_S = ????

Arrow_S.Location = new Point(Arrow_S.Location.X, Arrow_S.Location.Y + 1);

}

private void Start_B_Click(object sender, EventArgs e)

{

bool press= true;

if (press == true)

{

timer1.Start();

}

else

{

timer1.Stop();

}

Hi Gabriel ,

Solution is to use System.Timers.Timer timer1=new System.Timers.Timer instead of System.Threading.Timer obj.

and should be like this.

private void timer1_Tick(object sender, EventArgs e)
{
   Arrow_S = ????
   Arrow_S.Location = new Point(Arrow_S.Location.X, Arrow_S.Location.Y + 1);
   timer1.Stop();
}
private void Start_B_Click(object sender, EventArgs e)
{

   timer1.Start();

}

and make sure   Arrow_S = Arrows[n]; line code works as expected or not.
Let me know if any other concerns are there

Thanks

Did your program got compiled? You are putting List to an picturebox control. Moreover, you haven't put any stoppage in tiner tick event, as it will initialize and put the picturebox to that location.
