I was introduced to Microsoft Visual Basic back in 1995 (version 2.0!). I was already pretty proficient in FORTRAN and QBASIC, so it wasn't too hard to pick up. The flexibility of VB is substantial, and I have used it over and over again to build "tools" for various jobs, both "as an employee" and for "fun".
I've included some here. They are mostly "unsupported", meaning: my intent is to provide some tools for insight or time savings, not to become an application house. Certainly, if you find an error, let me know so I can fix it. If you have suggestions for extension or ease-of-use, by all means let me know...but no guarantees.
