I've been working on some COPP related code sample on Vista, I could not see the graph I had built. Was this because I was using the EVR instead of the VMR9 as I was on XP?
Well no. I read Loading a Graph From an External Process and registered Proppage.dll.
This was still not working.
As usual when using developer tools, I launched graphedt.exe as an administrator and voilà!
