You might wish to consider starting your application using an
ApplicationContext object which can manage Application startup/shutdown and
the interaction between your forms. If you have state which needs to be
shared between forms then I would suggest you manage this state in another
class.

On a side note, it sounds like you are building a UI with multiple windows
but no main form. This design might prove confusing to your users.

Can anyone post the ideas about managing the forms using
ApplicationContext for my above scenario

Hi kh

Thanks for ur reply and my client has given design spec like that. So
FormA will act as main form.

OK, I've got a sample working. Create a normal VS2005 Windows Application
and add a second form. Then edit the Program.cs file as follows:

using System;
using System.Collections.Generic;
using System.Windows.Forms;

namespace WindowsApplication1
{
class MyApplicationContext : ApplicationContext
{
public MyApplicationContext()
{
Form1 f1 = new Form1();
f1.FormClosing += new
FormClosingEventHandler(form1_FormClosing);
f1.Show();
}

void form1_FormClosing(object sender, FormClosingEventArgs e)
{
Form f2 = new Form2();
MainForm = f2;
f2.Show();
}
}

static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MyApplicationContext());
}
}
}

Now when you run the application it displays Form1. When you close Form1 it
displays Form2. When you close Form2 the application closes.
