Nothing that can't be bypassed by a determined cracker. You could have
your DLL look in the registry for something, look for another
preexisting file, require a password (either fixed or determined by
something within the user's system), etc. - basically, do the same
things that commercial programs do - but again, crackers bypass this on
a daily basis. (Although they usually crack apps to use the app, not
just one specific file.)

I don't usually store forms in DLLs but I would assume that it can be
easily done; others here will have that answer.
