While I haven’t looked extremely hard for it, I have finally found a copy of Extending MFC Applications with the .NET Framework in a store, MicroCenter of all places. The first thing I did was take a picture of page xxvi.
I put the book back on the shelf, then my dad asked me if I wasn’t going to buy it. Not at full price! Especially when Amazon has it for $35. When he pointed out that it was 30% off, I reconsidered and now own a copy of my first massively produced acknowledgment 😀
