Author(s): Shirley Wodtke ISBN: 1556225121 Publication Date: 01/01/97 Search this book: Table of Contents Introduction It is not necessary to learn the Windows API in order to begin using the Microsoft Foundation Class (MFC) Library of C++ classes; you do not even have to know more than a few basic C++ concepts in order to begin. I have been teaching extension classes through the University of California, Berkeley, since 1993. My students have ranged from expert to beginning Windows programmers. As an MFC teacher, I had to design a system that addressed the “common denominator” in the class, since so many of my students were put onto MFC projects and expected to “ramp up” in a matter of weeks, despite whatever their previous experience may have been. With the help of input from my students, I developed my simple one-idea-at-a-time approach to the MFC Library. I start with the most fundamental concept that a student needs to know and show the student how to master that one concept only. Then, I add the next concept. When exposed to a steady progression of clear ideas and exercises, my students have been able to truly master the fundamental concepts of MFC. This approach has worked for them, and I am sure that it will work for you. I adapted this book from my lengthy course notes, updating it for the new MFC compilers. But I use the same approach and the same examples. All of the examples have been student-tested for clarity and effectiveness in getting each concept across. All potential misunderstandings and errors have already been caught by my students and corrected. You can type in what you see and follow it line by line, because it will run on either Windows NT, Win3.1x, or Win95. Additionally, I have done my best to ensure that no code was “corrupted” during the production of this book and have included, as a backup (and so that you do not need to retype it), two diskettes with the original, typo-free code. My experience as a teacher has taught me that if you show a programmer effective, error-free code, the code explains itself; therefore, I Go! Keyword Go!
