A cool graphics and sound engine with examples, very cool.

A whole graphics engine and a sound engine with a full sample program. graphics engine has: Animatition with 1 picture, animation with array of pictures, bitblt, move sprite over background and Pixel manipulation; Sound engine has: Make a trackerbar from a picturebox 9that works), Play and stop wav file, Play and stop midi file, Play short wav file, Stop all sound and get Short File name. A midi and a wav file included for testing. The engines are in a seperate module each so you can make a copy of them and keep them seperate from the sample. the sample is fully commented but the engines are not.
