Loading a new form + using objects on other forms

[robcarr2]

Well like the title says I want to know how to interact with objects / controls that are on other forms.

e.g. if i had a text box on one form, i want to be able to change its text from another form.

I am using this code to load new forms :

            frmMain main = new frmMain();
            main.Show();

Is there a better way of going about doing this?

Thanks!
