Hi Muthu!
I don't think you can close the main form when the Child form is alive.
Try it. If you are not done, follow this.
Hide the Form1 while activating the Form2.
When you close the Form2, You must explicitly close the Form1.
I don't know how feasible this solution be but it serves your problem.
The overheads in this approach are
1. You have to maintain the reference of the Form1 in some global area (like static variable)
2. Though Form1 is hidden, it will be in memory till you close Form2.

Try using window parent/child relation using a script.
Here it goes
Call a window close function on click of login button as follows.
private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
LoginButton1.Attributes.Add("OnClick","openWindow('child.aspx?login=true');");
}
and write the following script code in the login.aspx
<script language="javascript">
function openWindow(url)
{
window.open(url);
}
</script>
in the child.aspx i.e. the page where you want to redirect the user after login, write a small script on body load as follows.
<html>
<head>
<title>Successfully Logged in!!!</title>
<script language="javascript">
function MaximiseWindow()
{
x = screen.width ; y = screen.height
window.resizeTo(x,y);
window.moveTo(0,0);
window.opener.close();
}
</script>
</head>
<body MS_POSITIONING="GridLayout" onload="javascript:MaximiseWindow();">
<form id="Form1" method="post" runat="server">
You are successfully loogged in....
</form>
</body>
</html>
But you are likely to get a warning message in IE , to check whether you want to close the window.
If you want to avoid this , you can open the login form also in a window.
Hope this helps you..
Cheers
Rags

Hi!
Use Thread to open another Form!!! Check this sample code...
private void btnLogin_Click(object sender, System.EventArgs e)
{
this.Close();
Thread th = new Thread(new ThreadStart(myForm));
th.Start();
}
private void myForm()
{
Form2 f = new Form2();
f.ShowDialog();
}
Regards,
Zabi.

Hi Muthu
Try This....
1) create a Object for Form 2
2) Activate Form2
3) Hide the Parent Form
For an Example
Here Form 1 is Parent Page (Login Page ) and Form 2 is Next Page.
private void button1_Click(object sender, System.EventArgs e)
{
Form f2=new Form2();
f2.Show(); // This Activates Child Form
this.Hide(); // This Hides Parent Form (Login Form)
}
Please forward ur Feedback..............

[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Loginfrm = new Login();
frm.ShowDialog();
//make boolean property IsCloseAll and default it to true
//So that if user hit cross he can go out
//and dont forget it to set it false at the event where user want
// to close login form and come to MainForm
if (frm.IsCloseAll != true)
{
Application.Run(new MainForm());
}
}
