I have a gazillion C++ (6.0) and VB (6) projects, many of them creating COM+ objects. How do I get an overview of who calls who? Anyone knows of a tool which can do that?
The code is not mine, and those who made it several years ago have all left the company...so it's not easy (and documentation as to who calls who and why is of course non-existent).

I hope someone can give me an idea. It's difficult to change things and make sure that everything is tested and nothing is broken without overview.
