How do I switch a VC6 project to Unicode

Question

I need to switch a VC6 project to Unicode. In VS2008 there's a very convenient combo box that lets me choose between ANSI and Unicode build, but in VC6 I couldn't find such an obvious way to switch to Unicode.

Answer 1

I'll post the solution as an answer. I needed to define _UNICODE as Hans said, and then I also needed to change the entry point function to wWinMainCRTStartup.
