object reference not set to an instance of an object

[Dakkar]

I have a code like this

using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.Drawing;
using System.Data.Odbc;
using System.Text;
using System.Data;
using Microsoft.Win32;
using System.IO;
using System.Diagnostics;
using System.Net;



public class sylagent : Form
{
private Process[] myproc;
private Timer t1;
private FileVersionInfo myinfo;
private int count;
private System.ComponentModel.Container components = null;
private String program;

public sylagent()
{
myproc = Process.GetProcesses();
count = 0;
this.Size = new Size(300, 300);
this.Location = new Point(100, 100);
this.Visible = false;

this.t1 = new Timer();
this.t1.Interval = 1000;
this.t1.Start();
this.t1.Tick += new EventHandler(t1_tick);

}

protected override void Dispose(bool Disposing)
{
if (Disposing)
{
if (components != null)
{
components.Dispose();
}
}
Process[] procuo = Process.GetProcesses();
for (int i = 0; i < procuo.Length; i++)
{
if
(procuo.ProcessName.Equals("client"))
{
procuo.Kill();
}
}

base.Dispose(true);

}

public void t1_tick(object sender, EventArgs e)
{
for (int i = 0; i < myproc.Length; i++)
{
if (this.myproc.MainModule.FileName !=
null)
{
this.program =
this.myproc.MainModule.FileName.ToString();
}

if (this.program[0] == 'C' ||
this.program[0] == 'D' || this.program[0] == 'E' ||
this.program[0] == 'F' || this.program[0] ==
'G')
{
this.myinfo =
FileVersionInfo.GetVersionInfo(this.myproc.MainModule.FileName.ToString());
}

if
(this.myinfo.OriginalFilename.ToString().Equals("connector.exe"))
{
this.count++;
}

}
if (this.count != 1)
{
this.Close();
}
this.count = 0;

}

public static void Main()
{
Application.Run(new sylagent());

}
}

Its not showing the line

Er, step through your code until you get to the line which throws the
error...

how can i instance the object

When you find which object is trying to be called, instantiate it...

put in a try-catch block. In the catch statement, write out the exception as
Console.WriteLine(exc.ToString())

When you do this, you get a complete dump of the location of the error.

Why does the timer's event handler rely on the Process[] myproc
created in the c'tor while the Dispose method creates its own
Process[]?

<HelpFile>
GetProcess - Overloaded. Creates an array of new Process components
and associates them with existing process resources.
</HelpFile>

If an existing process is killed, its associated component in the
array will still exist. The array element will have an object
reference set to an object that no longer exists.
