Answer 1

When you instantiate the second form, set the ShowInTaskbar property to False to prevent it from showing up in the Windows task bar.

You don't show the code where you instantiate and display the form, but something like this should work:

var secondForm = new Form2
                     {
                         ShowInTaskbar = false,
                         StartPosition = FormStartPosition.CenterParent
                     };

secondForm.ShowDialog();
