Visual C#.Net EventHandler Problem

Alper

Hi,i want to use pictureboxes in different eventhandler. Here are my codes:

private void buttonclick(object sender,EventArgs e) {
int i;
Form newform=new Form(); //creating form2
for (i=0;i<7;i++) { // loop that creates 6 picturebox
Picturebox newpicturebox=new picturebox(); //creating picturebox
newpicturebox.Name="picturebox"+i; //defining name
form2.controls.add(newpicturebox); //adding controls in form2
}
Timer newtimer=new Timer(); //creating timer to conrol pictureboxes that i defined in for loop
newtimer.interval=1000; //setting timer interval
newtimer.Tick+=new EventHandler(newtimer_Tick);//seting Timer's Eventhander

I want to control pictureboxes that i defined in for loop via newtimer_tick. How can i do this?

Compare this to your example and give this a shot in a form with a single button and a timer set to 250.

public partial class Form1 : Form
{

     public PictureBox[] pb = new PictureBox[6];
     public int seqNumber = 0;

     public Form1()
     {
          InitializeComponent();
     }

     private void button1_Click(object sender, EventArgs e)
     {
          Form newform=new Form();
          for (int i = 0; i < pb.Length; i++)
          {
               pb[i] = new PictureBox();
               pb[i].Name = "picturebox" + i;
               pb[i].Height = 20;
               pb[i].Width = 20;
               pb[i].Top = i * 25 + 10;
               pb[i].Left = 10;
               pb[i].BackColor = Color.Blue;
               newform.Controls.Add(pb[i]);
          }
          newform.Show();
          timer1.Enabled = true;
     }

     private void timer1_Tick(object sender, EventArgs e)
     {

          BlueAll();
          pb[seqNumber].BackColor = Color.Yellow;

          if (seqNumber < 5)
          {
               seqNumber += 1;
          }
          else
          {
               seqNumber = 0;
          }
     }

     private void BlueAll()
     {
          for (int i = 0; i < pb.Length; i++)
          {
               pb[i].BackColor = Color.Blue;
          }
     }
}
