How do you use bitmaps, wav files, and midi files?

[sandmann999]

Mostly interested in the bitmap loader.

What I'm really looking for (besides the code) is how the code works.

I have two bitmap loaders, one is about 5 lines long and the other is about 200 lines long. The 200 line code works pretty well and the 5 line code doesn't work at all (even though they swore they used it all the time.) But for some reason, the loader that was 200 lines long could only load bitmaps of certain dimensions, like an 80 pixel by 60 pixel. If these dimensions were off, the picture would become distorted.
Does anyone have a short bitmap loader? And please (more interested in this than getting the code), how does it work?

And if you have time, can you give me the code for wav files and midis? I use QB45.

Thanks a ton!
