In the solution explorer double click Program.cs (or right click and "View Code")

There you will find:

Application.Run(new Form1());

now change it to:

Application.Run(new Form4());

ereruh's post would mean the application closes when Form4 closes.

If the login dialog is only required at the start of the application then one solution is to open the login form before the Application.Run in program.cs as below.

DialogResult result;
using(Form4 loginDialog = new Form4())
{
    result = loginDialog.ShowDialog();
}
if (result == DialogResult.OK)
    Application.Run(new Form1());

Another solution is to open the login form in Form1.Load

private void Form1_Load(object sender, EventArgs e)
{
    DialogResult result;
    using(Form4 loginDialog = new Form4())
    {
        result = loginDialog.ShowDialog();
    }
    if (result != DialogResult.OK)
        this.Close();
}

Note: the above samples assume that Form4 is a dialog and returne DialogResult.OK if the login is OK. You will need to adjust the code to suit how your Form4 works.
