Hi, I'm new to this forum but im not new to C++. I currently program for Windows Using C++. This is my problem, I've learned how to use the language and create ADT's like graphs and binary trees, but I don't know where to start with application of my knowledge. I want to be able to apply my programming knowledge to my current computer, I want to make window applications and I want to understand how to use functions that come from the operating system like something as simple being able to tell my computer to shutdown or drawing a window and being able to sort through my file system. I know it sounds silly, but does anyone have any ideas?
