Hello,
I'm a 20 years experienced VIsual C++ Specialist.
Used to porting all kinds of C++ coe bases, to newer versions of Visual Studio/C++ and newer versions of WIndows.
If you're wanting to build this using VS 2015, presumably, you're OK with it being done on WIn 8.11 or Win 10?
I have both - on VMs, and have only just heped a gentleman on this site, port a VC++ 6 based Active-X control(20 years old code) to Windows 10.
Can I help u?
