Hi, I am developing an application in Visual Studio 2010 for this is have created Login form which takes credentials from SQL server 2008 and log in. Everything goes right till here. I wish that when user login with correct credentials login form should be closed and MDI parent form should be open. For this i wrote below code in MDI load event.

private void Main_Load(object sender, EventArgs e)
{

login login = new Login();
login.MdiParent = this;
login.Show();

}

and below code in Login forms Login butten

C#

private void LogBtn_Click(object sender, EventArgs e)
        {
          //Login logic here.

            int count = ds.Tables[0].Rows.Count;
            if (count == 0)
            {
                MessageBox.Show("Invalid password or Username", "Attention", MessageBoxButtons.OK, MessageBoxIcon.Warning);
            }
            else
            {
                Main main = new Main();
                main.Show();
            }

When I run this Application and enter the correct credentials on login form Login form expected to close but it won't close. When I close the Login form manually both MDI parent and Login form gets closed.

Please help me to resolve this issue.

Thanks in advance.

Solution 2

You have to close the login form when you show the main form. Check this.
Winforms: Close your form during Load event[^]
