form1 my_form=new form1();
my_form.show();

Except you should NEVER do this. If you want to show a modeless form, make sure it's a member variable, so you can work with it if you need to and so that pushing the button that creates it doesn't create a stream of them (or keep them in a list if this is what you want.)
