You can check to see if any form is active in your windows application. If form is active, then you can check which TextBox in the form has focus:

FormCollection fc = Application.OpenForms;

        foreach (Form frm in fc)
        {
            if (frm != null)
            {
                foreach (TextBox txt in frm.Controls)
                {
                    if (txt.Focused)
                    {
                        txt.Text = "your text";
                    }
                }
            }
        }
