I'm trying to add a binary filter to the file editor example that comes with Dev-C++. I'v added the option to select any file with the ".bin" extention. I'v been looking through the win32 api help file. I know i still need to tell the program how to read the file. I don't know win32 api. Does anyone know specifically what I should lookup in that help file that would help me add this filter?

thanks in advance
