This code is correct, but a form becomes invalid as soon as it is deleted.

frm.Show() should show the form modeless, except if a modal window is already 
displayed. Then it is shown modal. So it may be destroyed when frm.Show() 
terminates.

If you want to have public variables in the form to return some information, 
make them static. Static variables don't need any object to be valid.
