Access the object of one form from another form

Question

The window application has two forms. First is the login form "Login", containing the usual login details, username and password. The username and password are entered in the textboxes- txtUser and txtPassword. After authentication the second form "Form1" opens. How do I access the username entered in txtUser in "Login" so that I can display in "Form1"?
Please help.

If you're using .NET 2.0 or later and there's a label on Form1(called 'lblUser' say) for displaying the user's name then you can do this from the log-in form: Form1 frm1 = (Form1)Application.OpenForms[Form1]; frm1.lblUser.Text = this.txtUser.Text; The label does of course need to be declared as either public or internal to be accessible from the log-in form.
