Unloading Forms.

[viperbyte]

Hello everyone.

I have winforms app with a login form in which the user enters a user Id and a password. After the correct user id and password is entered, the main form is displayed. When the main form is closed the Login form is still there. I need to get rid of the login form. I haven't been able to figure out how to do this. How do I get to the the Main Form's closing or unloading event? And when I am able to get to this event what do I type to close the login form?

When do you show the "Login" form.? Post some code please.

Normally, I would do it like this in the main form Initialization code, or in a controlling class.

dim fLogin as new frmLogin
fLogin.ShowDialog();
isLoggedin = fLogin.WasSuccessfulLogin;
fLogin.Hide();
fLogin = null;

Hi Sotoasty.

I was so messed up that I didn't have any code to show. What I ended up doing was hiding the login form. But that alone wasn't good enouh becuase when I closed the main form Visual Studio had the Blue square (stop debugging) icon lit up. The program was still running. So I added a Form_Closing event by using the lighting bolt and added Application.Exit. So that took care of the running program. It all works now. Thanks.

in the login form

private void cmdLogin_Click(object sender, EventArgs e)
        {
            if (txtUserID.Text.ToLower() == "guest" && txtPassword.Text.ToLower() == "password")
            {
                frmMain frmObj = new frmMain();
                frmObj.Show();
                this.Hide();
            }
            else
            {
                MessageBox.Show("Login incorrect: UserID = guest and password is password");
                txtUserID.Text = "";
                txtPassword.Text = "";
                txtUserID.Focus();
            }
               
        }

in the main form

  private void frmMain_FormClosing(object sender, FormClosingEventArgs e)
        {
            Application.Exit();
        }

To me, this is the correct way to do it.
