I'm following this example: http://www.codinghorror.com/blog/2005/12/getting-started-with-indexing-service.html However, the conversion to dataset shows empty columns for my custom properties. If I use path or filename for the columns I get data back. I have set the properties to be cached, have tried both levels, and have rescanned full. I've tried this example on my desktop (windows vista 32bit) and on a Windows 2008 R2 server with the same results.
