I have a login form, that if successfully answered, launches another
form. The problem is that the login form remains even after I show the
main form. How do I get rid of the login form? 5 1803
JPSutor,
You could just set the visibility of the form to false, but I don't
think that is a good idea. Rather, you should do the following:
// Declare any variables you need to pass to your main form here.
// Create your form here.
using (LoginForm loginForm = new LoginForm())
{
// Run the login form.
Application.Run(loginForm);
// Set the variables which you will pass to your main form here.
// You need to do this because your form will be disposed after the
// using statement block is exited.
}
// Call your main form now.
// Pass in any parameters you might need to the constructor.
// A using block is not needed here because it is assumed
// that your program is exiting after this line (or
// shortly after that).
Application.Run(new MainForm());
Hope this helps.

Hi,
Just Hide() it, you cannot close it, as this is probably your main form (
the one you call from Application.Run )
Just hide it and use ShowDialog, after that just close the login form,
A piece of code will help:
void Login_Click( object sender, EventArgs e)
{
if ( CheckLogin() )
{
this.Hide();
Form newForm = MyNewForm();
newForm.ShowDialog();
this.Close()
}
else
{
MessageBox.Show("Incorrect login");
}
}
cheers,

I don't know if I like that. That's keeping around a window and all of
its associated controls for a pretty long period of time that you really
don't need to.
I'd rather show it, dispose of it, then show the main form. It leads to
better program design as well.

Hi,
You are right, but most probably the form will consist of two pairs of
textbox/label and two buttons, it would have almost no impact in the system.

I indirectly create a login form via "onload" of main, gather required info
then dispose of the form.
public bool getProfile(Form myForm) // Method of Class Instanciated by
Main_Onload
{
frmLogin myLogin = new frmLogin();
if(myLogin.ShowDialog() == DialogResult.OK){
ArrayList pal = new ArrayList(myLogin.sParameters);
if(pal.Count !=RequiredNumber)return false;
param1 = (string)pal[0];
param2 = (string)pal[1];
etc....
myLogin.Dispose();
return true;}
}
Hope this helps,
