Enable crossfading on Windows Media Player activex with C#

Question

 Hi all,
 
I am using Windows Media Player control v.12.0.9600.16384 on my Windows Desktop application which is actually a custom mp3 player. How can I enable Crossfading feature on windows media player control with C#? Also, I want to enable Auto Sound Leveling which I think it should be a relative process to Crossfading. I searched a lot of articles and forums but I couldn't find any C# code about using these two features.
 
Thanks a lot,
Peter
