DirectShow - Setting Webcam Properties

[antonybates]

Hi everyone,
Hope you might be able to help me. I'm using DirectShow with Visual C++ and capturing video from a webcam. What I wanted to know is how can I set up the webcam's properties from inside the program e.g. turning on/off auto gain control or setting brightness levels. The user can do this from the filter's property pages but I want to be able to do it in the program itself.

Cheers,
Tony.
