this is the code to the graphics tutorial on the main site and to be honest IM COMPLETELY CONFUSED

if someone could explain it a little better that would be great i jsut blantantly dont get it...i see the you can edit the color and location part and that char string part is the text but outside of that im pretty lost.

could anyway maybe summarize this a little better cause id like to know graphics somewhat sooner or later lol

since for a simple hello world program this is rather giant lol and since ive never done graphics programming before this is scarey looking

sorry if this is a little vague of a question but just general clearing up is what is needed so thats why its vague sorry but thanks anyway

LOL if your trying to learn Win32 Programming you should go here www.winprog.org
