That code is copyrighted and can't be republished without the author's
permission. The Access Developer's Handbook is certainly well worth the
investment if you're a serious developer.
I believe Ken Getz has made some code available on his website:
There are samples that will show him how to resize his own forms. All he
needs to do is set a reference to the MDE (it's not really an add-in, but
works like one) for the version of Access he needs, and use the same code in
his forms that is used in the sample forms. The code in the sample
applications can almost be imported directly with little if any changes.
There's also a large PDF with an explanation of how everything works.
