Listbox

[SteveCRM]

Sorry about all these question but I'm stuck at the end of my media player, the playlist and the timer. So what I need to know is how to use a listbox? Sorry this is kind of broad, but the main functions, like add and subtract, and is there something like "index" or any other way to grab its information?

Here are many useful listbox functions
You will need to include the <windowsx.h>
