Example: Let's say, I have a c++ project, and in it's Debug configuration I put a preprocessor definition like MAKUMBA_OBA=0x13 Then I add custom pre-link step which exec...
I'm creating a line chart control, and I need to write (or better say draw) the axis names and axis values.

I've got as far as telling VC++ to generate ASM files during compilation, which I never really used before. But it seems quite limited, like they are just extra files thrown out during the compilation. I'd thought maybe the ASM/C++ code might be linked, so I can jump from C++ directly to the generated ASM code? Or could set breakpoints i...
