So You've Inherited a VB6/VBA Project!

Congratulations! You've inherited a large, complex, Visual Basic 6 or VBA
project written by another programmer. In terms of transmissible conditions...
well, at least it's not AIDS.

[Sidebar: why "Visual Basic 6 or VBA"? Well, in 2000-something, Microsoft
 introduced the .NET platform. This is a managed runtime in the vein of the
 Java virtual machine, and one of its selling points was the ability to
 compile multiple source languages to .NET assemblies. Visual Basic was chosen
