Obtaining data value with memory address

[RonF]

I am working on a project to dynamically gather audio information from my sound card and process it real-time. I can successfully create and fill a buffer with audio information, but the API I am using only sends back a beginning address of my data buffer. This buffer contains data values I need to read individually as bytes (magnitude of volume). With only the beginning buffer address, how can I read the value of the first byte, the second byte, .... the last byte? I am using VB(5) and running under Win98.

Any help in cracking this question, along with example snipets of code, would be greatly appreciated.
