Let me introduce: (1) Applicable to Visual C++ version 6.0; (2) Compiled by Taiwan’s “Bit Culture Research Laboratory”; (3) The characteristic of this book is that it does not directly introduce the use of MFC's Wizard, but starts with manually writing simple window programs, step by step, and is suitable for VC beginners to get started and advance; (4) It’s just the source code of the book. I haven’t scanned the electronic version of the book yet. (5) Many key positions in the source code are accompanied by Chinese explanations, which is a key point. (6) I upload these things that I regard as treasures with gratitude to CSDN. From here, I downloaded a lot of precious information and answered a lot of doubts. I don’t have anyone studying VC around me. Fortunately, I can find good teachers and helpful friends here. (7) I hope the information is helpful to everyone or has value for collection.
