Visual C + + 6 Add-in Programming instance

Recently I spent some time learning how to write Add-in for Visual C + + 6.0. This is an interesting question, but overall, documentation and sample procedures are still scarce (more rare in Chinese). So I decided to write out some of my own learning process, and share with you.

Frequently asked questions about Visual C + + add-in
