Tomasz Kornacki · Answer

Try this code: public partial class MainForm: Form { LoginForm f; object customData; public MainForm() { f = new LoginForm(); f.ShowDialog(this); objectCustomData = f.CustomProperty; InitializeComponent(); } } And after succesfull login you should call this.Close() inside LoginForm. To collect data from LoginForm (like login information) define as many properties as you need. Cheers Tomek K.

You can write like this also:: private void button1_Click(object sender, EventArgs e) { this.Hide(); Form f = new Form(); f.Show(); f.FormClosed += new FormClosedEventHandler(f_FormClosed); } void f_FormClosed(object sender, FormClosedEventArgs e) { Application.Exit(); } Regards, D.M.R.Santosh

Hi, You can do like this :: this.Hide(); Form f = new Form(); f.Show(); under the button click then the form1 will hide and shows you the new form, when you want to close the form then you can write as Application.close(); Regards, D.M.R.Santosh

if login will be successful then hide the login form. or you can do onething. in main form( means page which opens after successful login). you can take one bool variable loggedin. in that form_load you can check whether the user has logged in or not using loggedin variable. if not then open login window. and if user entered valid username and password then assign one variable "loggedin = true " in the main form. if user entered wrong password then ask user to enter valid password or you can exit from the application. --------- dont forget to accept answer, if it helps you.

You can use the Hide() and Show() methods of Form class for this purpose. Hide the login form, display the second form. Finally, when you want to exit, use Application.Exit(). -Mamta
