Hello Sanjay
you can use program.cs for managing this like
Supose Form1 is a login form and Form2 is mdi form.
now you can write code in program.cs like:
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Form1 login = new Form1();
login.ShowDialog();
if (login.DialogResult == DialogResult.OK)
{
Application.Run(new Form2());
}
else
{
}
}
and write code for login check on the click of button1_Click event of Form1 like:
private void button1_Click_1(object sender, EventArgs e)
{
if (LoginCheck)
{

DialogResult = DialogResult.OK;
this.Close();
}
}

check this

thanks
