"Always listen to experts. They'll tell you what can't be done and why. Then do it." [Robert Heinlein]
Criticism should be constructive - in general I try to show how things could or should positively be done. But during more than 20 years of Excel © practice I encountered some examples which could and maybe should be avoided. A positive list on Excel © VBA I have presented here.
Please look at this list as an intellectual challenge and take it with a grain of salt.
