Please tell me how to make a button from scratch with Dev-C++. Most places I looked showed how to make one with the premade code, or required programs I didn't have. I have Dev-C++ 5.0 beta 9.2 (4.9.9.2) (9.0 MB) with Mingw/GCC 3.4.2. Please show me an example, the output, and explanation (optional).
I think you need to be more clear on what you mean by a button. If you mean graphics, then standard C++ doesn't support that, and you will need to look into graphic libraries.
It's been some time since i last used DevC++, but IIRC, there is a Win32 project template. You can follow the guide below, there are explanations on making different kinds of buttons in under Windows. Of course, you can start with an empty project, too.
