In the first part of my manifesto, I outlined why I think we should really change the way we code.

A little while ago, I made a blog post on why I think we no longer need Hungarian Notation. Truthfully, it’s not the first time I’ve advocated for doing something against the grain.

Continue readingIt’s time to say “Goodbye,” to Hungarian Notation
Most of us code using the Hungarian notation style when writing VBA code. Basically, that’s when you prefix an abbreviated description of a variables’ type or class in front of its name.
