title: How do I set the properties of a DirectShow Filters
body: <p>Ok I have this 3d tv Transformation Filter. I can easily configure its properties by using GraphEdit, right click on its properties and set whatever I want.</p>
  
  <p>Now I want to set the properties automatically  by building a Filter Graph in C++.
  I've read up the Windows SDK documentation and find out that I have to use the IKsPropertySet function (correct me if i'm wrong).</p>
  
  <p>I have to use IKsPropertySet::QuerySupported to check whether it support this kind of property or not. And to do that, i have to know  the </p>
  
  <p>dwPropID</p>
  
  <p>[in] Identifier of the property within the property set. </p>
  
  <p>But how can I get that ID. Like this filter have the property of adjusting horizontal and vertical, but i cannot find the ID of that properties.</p>
  
  <p>Is there anyway to list down all the properties ID that a filter support ? </p>
