Using the TreeView control and Mixer Services


The MIXTREE sample demonstrates how to use a TreeView control and the mixer 
services. If a mixer device is present, then the TreeView control and text 
displays reflect actual components of the mixer device. If no mixer device is 
present, then simulation data will be used to generate the TreeView control 
and text displays.

This sample is based on the INITREE sample. It is a 32-bit only sample.
