   // Create a new DateTimePicker
   DateTimePicker dateTimePicker1 = new DateTimePicker();
   Controls.AddRange(new Control[] {dateTimePicker1});
   MessageBox.Show(dateTimePicker1.Value.ToString());

   dateTimePicker1.Value = DateTime.Now.AddDays(1);
   MessageBox.Show(dateTimePicker1.Value.ToString());
}

Public Sub New()
   ' Create a new DateTimePicker
   Dim dateTimePicker1 As New DateTimePicker()
