Getting User Feedback and Using Edit Boxes
There are two different programs which come in this *.zip file. One of them is about User-Feedback. The other code is about using edit boxes. This also comes with a really great e-book on: “Writing your first dialog based application using Visual C++.” I strongly recommend you read this e-book if you are just starting to program in Visual C++ (Uses MFC).
