Hello Folks,

I'm working on a C++ project that requires me to unmount and remount volumes on a flash drive, and from what I can tell, the system services I need to access are implemented using COM.

http://msdn.microsoft.com/en-us/library/cc227526(v=PROT.10).aspx[^]

I believe that I am supposed to create an IVolumeClient object using CoCreateInstance, and then use that object to communicate with the Disk Management server.

My confusion comes when I try to find any kind of interface to IVolumeClient on my development machine. Where would I find a C++ header file for the IVolumeClient interface, and where would the proper CLSID and IID values for CoCreateInstance be found?

Thanks for your time,

Ron Aldrich
