So you want only a single instance of the form to be available at one time,
unlike say Word opening multiple document windows in the MDI parent?  If
this is the case just check to see if the form is Nothing when the user
click the button.  If it is nothing, it hasn't been created.  Create and
show it.  If it isn't nothing just show it.
