What language is CleanUp! written in?

CleanUp! was originally written in an early version of Visual C++ (I can't remember what version now) using Microsoft Foundation Classes (MFC). Version 1 was developed under Windows NT 4.0 Server and Windows 95.

It has since "migrated" to Visual C++ 6.0. CleanUp! 3.0 was developed primarily under Windows 2000 Advanced Server and Windows 98.

CleanUp! 4.0 has been developed primarily under Windows XP (Home) and tested most heavily on Windows 98 and Windows 2000 (Professional).

I originally used Visual SourceSafe under Windows NT for version control until that machine crashed on me - big time. I have since migrated the source code into CVS hosted on a machine running Gentoo Linux. This setup has proven to be much more stable and reliable.
