Still have issue getting it to compile under VS2015. I see three options. 1. Install and go back to VS6.0 2. Install and go back to VS2012 3. Stay with VS2015 and rework code. I am looking at doing option three. I will write tests based on the current code and write new code to make those tests pass. Results should be code that is functionally the same as old code, but compiles under VS2015. Let's see how this works for just the Q3.
